20. Subtract the greatest negative fidelity error from the greatest
positive fidelity error for calibrated amplitude steps from -10 dB
to -70 dB. The results should be SO.6 dB.
21. Subtract the greatest negative fidelity error from the greatest
positive fidelity error for calibrated amplitude steps from -10 dB
to -90 dB. The results should be 1.1.5 dB.
