Figure 3. Output Noise versus Source Resistance Figure 4. Spectral Noise Density

Figure 5. Burst Noise Test Circuit

Unlike conventional peak reading or RMS meters, this systemwas especially designed to provide the quick response timeessential to burst (popcorn) noise testing.

The test time employed is 10 sec and the 20 V peak limitrefers to the operational amplifier input thus eliminating errorsin the closed loop gain factor of the operational amplifier .
