$ rtl_test -hrtl_test, a benchmark tool for RTL2832 based DVB-T receivers

Usage: [-s samplerate (default: 2048000 Hz)] [-d device_index (default: 0)] [-t enable Elonics E4000 tuner benchmark] [-p[seconds] enable PPM error measurement (default: 10 seconds)] [-b output_block_size (default: 16 * 16384)] [-S force sync output (default: async)]
