Quality control

IWATSU believes that customers useIWATSU instruments with confidencebecause of their high quality. In order tomaintain that quality, IWATSUinstruments are thoroughly tested atevery stage of the production process —from designing to manufacturing — toensure that they meet IWATSU qualitystandards.

TRACEABILITY

A major reason why IWATSU instrumentshave such a high reputation is that theyare fully compliant with the Japanesenational standards set by theElectrotechnical Laboratory. Accordingly,they also comply with internationalstandards. The chart below illustrates IWATSUtraceability.

1. Frequency bandwidth1-1. What is frequency bandwidth?Iwatsu’s lineup includes 20, 40, 100, 200, 250, 400, and 500 MHz bandwidth oscilloscopes.Selecting the most suitable bandwidth:For example, a 100 MHz oscilloscope displays a 100 MHz 1V (p-p) input signal on the screen with an amplitude of approximately 0.7V (-3 dB). Fig. 1 The displayed amplitude depends on the input signal frequency. The higher the frequency input, the smaller the amplitude display.The relationship between frequency and 0.7 times amplitude can be expressed as

f=1/ (2 πR C)Then what about a 33 MHz input signal?The ratio between 33 MHz to 100 MHz is equal to 3 times.

A = 31+32

310

= = 0.949

Tr = 3.52+102 = 10.59ns

Tr = A2+B2+C2+D2 ···· N2

A = R1+R2

In this case, a 5% error is included.Normalized expression for formula (1): R = RATIO A = Amplitude

The displayed pulse has a rise time about 5% slower than the original 10 ns.Normalized expression for Formula (3): A is scope, B is pulse, C is amplifier, D is cable.

Fig 4 shows the relationship between rise time ratio vs. displayed error.For example, if scope rise time and pulse rise time have the same value, then theTr ratio is 1.In this case, a 41% error is included.If the ratio is 3, the error is only 5%.

1-2. The rise time of an oscilloscopeFormula (2) shows the relationship between the rise time (10% - 90%) Fig. 2 and the frequency bandwidth.

f = 0.35 / Tr (2)

With Formula (2), the rise time of a 100 MHz oscilloscope is calculated as 3.5 ns.The value 3.5 ns is the displayed rise time on the 100 MHz scope screen when 0 ns rise time pulse isapplied to input terminal. Fig. 3How much rise time (Tr) is displayed on the 100 MHz oscilloscope screen when a 10 ns rise time pulse isapplied to input terminal?The calculation is as follows.

(1)

Fig. 1

Fig. 2

Fig. 3

(3)

Fig. 4

Use this rule of thumb when selecting an oscilloscopeThe oscilloscope bandwidth should be at least 3 times the test circuit bandwidth or the rise time should be less than 1/3 of the test circuitswitching time.

Oscilloscope bandwidth > 3 x Circuit bandwidthOscilloscope rise time < 1/3 Circuit switching time

2. ANALOG and DSO (Digital Storage Oscilloscope)There are basically two types of scope — analog and digital storage.This section explains the differences between these scopes so you can better understand which type is best suited to your needs. Iwatsu offersboth types.

ANALOGREAL-TIME Does not have storage capability

SS-78 seriesSTORAGE Stores waveforms on the screen of a special CRT

TS-8500DIGITALStores waveforms as digital data in a semiconductor memory. Uses an A/D converter.

Differences between Analog and DSO are follows.DSO Advantages2-1 Single shot captureAnalog oscilloscope needs trace recording camera.Advanced skill required for capturing.DSO can store a single shot waveform in memory.

2-2 Pre-triggerAnalog oscilloscope can display a waveform only about 20 ns before the trigger point.DSO can display a waveform up to the memory length.

2-3 Low speed motion (low frequency) recordingAnalog Spot beam moves from left to right and disappears.Digital Stable display remains after waveform disappears (same as recorder).

2-4 Analysis and data outDSO can calculate the captured data and output the data to a printer or PC.

Analog Advantages2-5 Easy operation with unknown signals.Even if you have no idea what type of signal is being sent to your checking circuit, you can easily obtain the waveform with an analog scope.With DSO you have to know the signal frequency, amplitude and shape, then set the DSO to the proper range to prevent a aliasing errors.

2-6 No aliasingAliasing occurs when the input signal frequency is higher thanhalf the sampling frequency.Signal frequency (1 MHz) > 1/2 sampling frequency (2 MHz) Aliasing shows a lower frequency waveform with a waveformshape similar to the original waveform.Fig. 5 shows an aliasing waveform.The original waveform is sampled by a sampling pulse. Sampleddata (Dots) are connected to make an aliasing waveform.To avoid aliasing with a DSO, the sweep rate has to be setproperly.An analog scope, on the other hand, can display the waveformwithout aliasing regardless of the sweep rate.

2-7 Fast display update rateA DSO normally captures data at a maximum rate of about 100 times/sec.Fig. 6An analog scope, however, can display a signal waveform at rates of 200kto 1 million times/sec max.With a sweep rate range above 1 ms/div., a DSO may fail to capture anunknown anomalous signal.With a very fast sweep rate of 1 µs/div. or higher, a common analog scopecan capture unusual anomalous signals.In some cases, the waveform may not be visible or may be too dark tosee.In this case, an analog storage scope such as the TS-8500 can be used toview the waveform. The TS-8500 can capture a single shot waveform at500 ps/div.

2-8 Brightness informationAnalog scopes display a signal histogram for brightness information.Frequent signals are displayed in the bright portion and infrequent signalsin the dark portion.A DSO displays any waveform with the same brightness points.Recently, some DSOs have been introduced capable of displaying brightness in the same way as an analog scope.

2-9 Low costFor example, the price of an analog scope capable of displaying a 100 MHz signal at 2 nsec/div. is less than half that for a DSO with higher V, Hresolution.

Analog Storage Oscilloscope TS-8500

TS-8500DC – 500 MHz, 4 CH

m Ultra-high speed storage capabilityNewly-developed scan converter tube allows capture of single shotphenomena even at the highest sweep rate.For instance, it can display the leading edge of a 6.25 div amplitude,1 nsec rise-time pulse or any part of a 3.2 div amplitude, 500 MHzsine wave in a single shot sweep.

m Maximum writing speed for all rangesand guaranteed wide bandwidth fromDC to 500 MHz

Unlike a digital storage oscilloscope, the TS-8500’s waveform displaycapability and frequency bandwidth are not dependent on the sweeprange. As a result, aliasing does not occur.

m “Burn-free” because waveforms arestored by the CCD

Ultra-High Writing Speed AnalogStorage OscilloscopeThe TS-8500 ultra-high writing speed analog storageoscilloscope allows precise observation of high-speedsingle shot phenomena and sporadic noise (glitch). A newly-developed scan converter tube makes itpossible for this scope to capture noise which appearsin repetitive signals as well as high-speed single shotphenomena.Featuring the same high levels of operability and basicperformance as our popular 470 MHz/400 MHz analogoscilloscopes (SS-7840H/SS-7840), this scope requiresno special training or operation, making it an idealsolution to the common problems encountered everyday in electronics engineering.

m Time base dual delay functionTwo independent delay time settings are provided for B sweeps,allowing delay magnification of two signals.

m Examples of observed waveforms

Constellation waveformShows phase and jitter of a 256QAM signal. This is one of themodem evaluation methods. Jitter can be checked by the sizeof the spot waveform while the phase can be evaluated by theshape of a square formed by four spots.

m Easy-to-save panel setup Panel setup conditions can be saved via front panel operation with nospecial knowledge required, unlike when using GP-IB commands.

m Quick and direct readout requiring no m interface

When used together with an optional Manual Box, setup conditionscan be recalled or saved quickly and easily.

The new Programmable Oscilloscopes SS-7840P/ SS-7811P/SS-7804P have been developed exclusivelyfor manufacturing line use. With a built-in CPU,programming functions are made simple, and the setupdata can be up loaded to the oscilloscope from apersonal computer. This greatly reduces the re-programming procedures that are inevitably requiredwhen the product on the line is changed.Quicker response (when compared with the control viaGP-IB interface) also contributes to improvements inproductivity.Iwatsu's peripheral components (optional accessories),developed using our long experience and waryachievements, also simplify the re-configuration of yourmanufacturing line.

• Quick and direct readout requiring nointerface

• Easy-to-save/recall panel setup• Flexible Bank setting capability• Bulk of panel setup data can be saved in

and loaded from a personal computer

m Concurrent loading of setup conditionsWhen personal computers (IBM PC/AT and compatibles) are used,panel setup data can be downloaded onto the floppy disk or uploadedto the oscilloscope together. This feature greatly reduces setupprocedures required for re-programming two or more SS-7800PSeries oscilloscopes.

m 12-character comment input capabilityfor each setup data

Up to 12 characters can be input as a comment about eachmanufactured product (name, etc.), allowing effective use of setupdata.

m Compatible with 8-bit BCD binary codein conventional automatic control line

The 8-bit BCD (binary coded decimal) binary codes that are used forcontrolling the other equipment in the manufacturing line can be usedfor controlling the bank and program step numbers of the SS-7800P .

m Flexible bank settingThe 255-step memory area can be used in various configurations,from a single bank with 255 steps to 63 banks with 4 steps each. Thisis convenient when 1 bank is used for each manufacturing product.

Soft magnetic parts made of ferrite play important rolein electric components as they are used in a broadscope of applications ranging from lower frequenciessuch as yokes for micromotors, to high frequenciessuch as flyback transformers, deflecting yokes, high-frequency transformers and magnetic heads.In actual operation, these magnetic parts displaycharacteristics different from direct current magneticcharacteristics or characteristics measured with anLCR meter.

IWATSU’s Ultrawide-bandwidth B-H Analyzers are designed to meethigh-performance requirements for various applications related tothe research, development and inspection of soft magnetic materials.

n Core loss measurementHigh-frequency transformers used in switching power supplies andDC-DC converters suffer current leakage, which increases as thehandled frequency increases. The causes of the leakage includehysteresis loss and eddy-current loss. The heat generated by lostcurrent causes the temperature of the equipment to rise, making itdifficult to reduce the size of equipment. Measuring core loss of softmagnetic parts provides the best solution to minimizing loss andenabling further reductions in equipment size.

n B-H curve measurementRapid progress has been made in production of magnetic heads andthin-film sensors. However, no systems for measuring the B-H curvein the high-frequency domain have been available. Until now,measurement of thin-film materials has been done using DC B-Hcurve measurement by VSM or µ-measurement by LCR meters. TheSY-8232 and SY-8217 B-H analyzers are equipped with a thin-filmmeasurement function for use in measurement of high-frequency B-Hcurves of thin films. As a result, more accurate analysis of thin-filmmaterials is now possible.

n Permeability measurementYoke materials used in motors, actuators and relays are usually madeof silicon steel, soft iron, permalloy and stainless steel. However,these materials tend to cause differences in magnetic characteristicsaccording to the processing and heat treatment.The B-H analyzers are capable of measuring the magneticcharacteristics of these parts, providing data that will facilitateimprovement of these materials.As for ordinary ferrite cores, the B-H analyzer can measureinductance characteristics (SY-8232) and m-characteristics.

<Development system>All IWATSU’s magnetic characteristic measurement instruments aredeveloped using our original analog technologies, extensive fieldexperience, and by anticpating and responding to user demands.

The SY-8232 high-frequency B-H analyzer is theflagship of IWATSU’s line of B-H analyzers. It has ahigh-frequency B-H curve tracing capability over anultrawide-range measurement frequency from 10Hz (optionally 1 Hz) to 10 MHz.The SY-8232’s compact design makes it ideal fordesktop use. It incorporates features required formeasuring high-frequency magnetic characteristics,including an oscillation circuit, power amplifiercircuit, high-speed digitizer, operation control circuitand a printer.The built-in 25 VA power amplifier allows directmeasurement of small specimens such as magneticheads, while use of an external power amplifierenables measurement of large amplitudecharacteristics and saturation characteristics ofpower ferrite or ultrathin amorphous materials. Thelower limit frequency is as low as 10 Hz (optionally1 Hz), permitting the measurement of near DCmagnetic characteristics of soft magnetic materials.As the analyzer allows both near DC and AC, themeasurements of coercive force (Hc) related tomagnetic wall production, migration and extinctioncan be more effective and research and testing inmaterials development can be performed morequickly.

The SY-924 measurement pod has been designedfor high-frequency, high-magnetic field measurementof thin film samples (> 100 kHz, 100m Oe to 10 Oe).In the pod, an excitation winding and acompensation coil-system detection winding are builtin.Measurement can be performed easily by insertingrectangular samples, which are vacuum-evaporatedon a glass plate (or a non-magnetic substrate), intothe sample insertion hole on the SY-924.

Thin Film Measurement Pod SY-924 Option for B-H analyzers

<Major applications> Thin film materials for magnetic heads

Measurement of high-frequencysaturation characteristics (Magnetic field > 100m Oe)

Measurement of high-frequencypermeability characteristics (Magnetic field > 100m Oe)

The SY-942 measurement pod has been designedfor low-frequency, high-magnetic field measurementof thin film materials with thickness around 500 Å (> 1 kHz, 100m Oe to 10 Oe). In the pod, anexcitation winding and a compensation coil-systemdetection winding are built in.Measurement can be performed easily by insertingrectangular samples, which are vacuum-evaporatedon a glass plate (or a non-magnetic substrate), intothe sample insertion hole on the SY-942.Low-frequency measurements (1 kHz to 100 kHz)are required to provide high sensitivity in detectionbecause the induced voltage level is about µV atthese frequencies. The S-942 pod features inducted

Measurement of high-frequency saturationcharacteristics (Magnetic field > 100m Oe)

Measurement of high-frequency permeability characteristics (Magnetic field > 100m Oe)

High accuracy is difficult to achieve when measuringlow-frequency magnetic characteristics such assaturation B-H curves of small soft magneticsamples or low-permeability samples because theamount of voltage induced by magnetization is small.The induced voltage detection sensitivity of the SY-926 pod is increased 100 times (compared to thestandard pod) for low-frequency magneticcharacteristic measurement. By combining it with theS-8232 B-H analyzer, it can be used with excitationfrequencies from 10 Hz to 100 Hz.

Rod or rectangular board materials (metallic, ferrite, etc.)

Effective permeability measurement

The SY-927 is the optimum choice for measuringand estimating the AC initial permeability andinductance in high frequencies for ferrite cores, dustcores and magnetic head materials.This pod was developed by enhancing the detectionsensitivity of the standard pod (SY-921) in order todeal with measurement in low magnetic fields andlow magnetic flux density. The excitation anddetection windings of the sample to be measured areconnected to four terminals on the pod. In the pod,an excitation current detection circuit for ±1 mA to±200 mA and an induced voltage detection circuit for±50 mV to ±50 V are built in.

n Core loss measurement in high-frequency power transformers (using an optional external poweramplifier)

The core loss characteristics of ferrite cores used in high-frequency power transformers can be measured easily by usingan external power amplifier (optional). When the continuousmeasurement function is used, frequency characteristics (Pcv - f) of the core loss can be quickly obtained.

By changing the display mode, the hysteresisloss and eddy-current loss can be approximatedusing the least square method, permittingestimation of the differences in composition andconstruction of materials.

Furthermore, the frequencycharacteristics of amplitude permeability(µ - f) can be shown by changing thedisplay mode.

n B-H curve measurementn Measuring the high-frequency

amorphous coreSmall-amplitude to supersaturating B-H curves can bemeasured and the results can be overlapped by using anexternal power amplifier (optional). This is suitable for theanalytical measurement of magnetic cores foroversaturating reactors.

By changing the display mode, a permeability curve (µ -Hm) or magnetization curve (Bm - Hm) can be obtained.This ensures much more stable results with high-frequencymaterials than can be obtained with conventional DCmagnetization measurement.

n Measuring the low-frequency B-Hcurve by substituting the DC-BHcurve tracer

The SY-8232 is optionally capable of measuring 1 Hz, so itcan be used to estimate static characteristics (instead ofusing the more complicated DC-BH curve tracer). Withordinary size samples, it can effectively be used for thestable measurement of Bms and Hc.

n Permeability measurementIn general, tan s is used as the loss factor for magneticmaterials used in inductors. With the SY-8232, complexmagnetic permeability (µ’, µ’’ ) can be measured toestimate loss.

In addition, the SY-8232 can measure permeabilitywith either the primary coil or secondary coil method.This makes it possible to estimate the winding loss(copper loss) separately.

n Thin film material measurementThin film materials can be measured with the B-H curvemeasurement and permeability measurement. The thin filmmeasurement pod (optional) is required for thesemeasurements.

n Measurement of magnetic headmaterials

Magnetic heads are measured in the toroidal shape beforemachining and in the head assembly stage after machining.As the SY-8232 can perform excitation at max. 10 MHz andmin. 10 Hz (optionally 1 Hz), the unit can estimatecharcateristics ranging from static to high-frequency on itsown.

n Measurement of magnetizationdynamic characteristics ofelectromagnetic parts

Electromagnetic parts such as relays, solenoids and valvescan be estimated using the optional pulse excitationmeasurement function.

(Example with MnZn sintered ferrite)

(Example of MnZn ferrite)

(Example of processing by PC)

Example ofmeasurement ofbcc-Fe-Hf-C thin film(40 mm x 3 mm)

Low-Hc materials can beestimated with excellentreproducibility because themeasurement results areobtained in quantitative figures.

(Example of measurement of the magnetization-frequencycharacteristic of relay)

n Inspection of high-frequency powertransformer core

More accurate inspection must be performed onthe core of a SWPS transformer, in order todecrease core loss. The B-H analyzers havebeen specifically developed as optimummeasurement tools for manufacturing andinspection. They can perform stable core lossmeasurement quickly and simply.

n Saturation B-H curvemeasurement of MnZnpower ferrite cores

The results of measurement at 50 Hz present agood correlation with the DC-BH curve tracermeasurement, and offer highly stable results. Itcan be applied to the inspection of the Hc value.

n Measurement of metallic materials using pulseexcitation

When metallic materials used in step motors and actuators are measured byapplying pulse excitation, magnetic characteristics close to what would bedisplayed in actual operation can be identified.

(Example of measurement of low-loss MnZn ferrite)

Note) Both the DC curve tracer and B-Hanalyzer excite Bms at 1000 A/m and Hcat 100 A/m.

1. OverviewThe key measurement method used by oscilloscopes is probing. When measuring a circuit, a small amount of energy is taken out throughthe probe. The less energy taken out, the less effect on the circuit. It is necessary to consider the influence of the probe on the circuit beingtested (Loading effect). Even if you have a high bandwidth scope, improper probing can result in low bandwidth measurement and low fidelity.

2. Classification of ProbesProbes are categorized as passive probes, simple resistance dividers, and active probes, which require an external power supply (such asFET probes). These categories are further divided into voltage probes and current probes.

Probe Passive Voltage 1:1 Probe 10:1 Probe High voltage Wide bandwidth

Current

Active Voltage FET probeDifferential, etc.

Current

3. Reasons For Using ProbesWhat problems will occur if a wire is connected directly from the input terminal of the oscilloscope to the circuit being tested?1) Easily affected by noise.2) The frequency bandwidth is reduced.3) Loading effect is greater.

Problem 1): Can be mitigated by the use of coaxial cable or shielded wire. However, this solution does not work for problems 2) and 3).

Problem 2): When a wire is directly connected, the frequency bandwidth is limited by the inductance and stray capacitance of the wire. The use of a 10:1 probe, however, can eliminate this influence.

Problem 3): If the wire is connected directly when the oscilloscope input is viewed from the side of the circuit being measured, thecapacitance and inductance constitute a load as is the case in problem 2). In this case, there is still a high load even if a shielded wire is used for connection.

Then, what will happen when a 10:1 probe is used?Let's compare the 10:1 probe and shielded wire.Probe: 1.5 m 10:1 probe with an input capacitance of 15 pF

Shielded wire: 1.5 m total capacitance 150 pF(unit capacitance 100 pF/m)Oscilloscope : Input capacitance of 30 pF

Conclusion: Loading effect of the capacitance will be reduced from 180 pF (150+30) to 15 pF.

But the amplitude will be attenuated to 1/10.

4. How to Use Probes4-1 Probe compensationBefore starting the probing, it is necessary to compensate the probe. Probe compensation means compensation for the probe frequency characteristics. Fig. 1Adjust C3 so that the following relationship can be obtained:R1 x C1 = R2 x (Cc + C2 + C3) : Cc = Cable capacitanceIf measurement is performed with no probe compensation, an extreme error in signal amplitude may occur around 10 kHz.

4-2 Input capacitanceInput capacitance can be reduced to 15 pF by using a probe as described in Section 3. This section looks at the influence of the inputcapacitance. (Loading effect).

p78-83 00.9.28 4:39 PM ページ 78

5. Special purpose probes

5-1 FET ProbeThe prime feature of the FET probe is that it has a low input capacitance of approx. 2 pF.

5-2 Wide bandwidth probeThis probe is most suitable for measuring a 50 Ω signal system, etc.Although the input resistance and capacitance are lower than other passive probes (500 Ω and 0.7 pF for 10:1 and 5 kΩ and 0.6 pF for100:1), the values are high enough for a 50-ohm system.At the same time, these probes maintain a high impedance of 100 MHz or more.

5-2-1 Comparison of probe specifications and input impedanceThe input impedance and frequency characteristics of these three types of probes and 1:1 probe are as shown in Fig. 8. Input impedance ofthe 10:1 probe is lower than that of the FET probe when the frequency exceeds 10 kHz. The input impedance of 10:1 and 1:1 probes is lower than that of the wide bandwidth probe within the range of 10 MHz to 1 GHz.

5-5 Current ProbeCommon probes pick up voltages, but a current probe is used to directly measure currents by clamping a wire without cutting.

Insertion impedanceCurrent probes can affect a circuit with insertion impedance.The value of insertion impedance depends on the individual model, but as a rule of thumb, the value is normally less than 0.1 ohm.

Fig. 9 shows the measurement of the ripple current that flows into a smoothing capacitor in a power circuit.

Isolation voltageThe isolation voltage of a current regulator is 300 V. Be careful when measuring a switching regulator circuit (Fig. 10).

Point 1 is best, point x is worst. (1 > 2 > 3 > x)Point 2 is slightly affected by voltage interference.Point 3 is equal to the rating limit (300 V).Point x is over the rating limit, and is greatly affected by voltage interference.
