Level and distortion measurement
Using HP8903B low distortion source
distortion is measurable down to -80dB at levels from 0.6 to 6.0v, from
20Hz to 20KHz.
From 20KHz to 100KHz this deteriorates to -65dB.
Source output (50 or 600 ohm)
is from 7mV to 6V flatness within 4% over 20Hz to 100KHz.
Level measuring capability,
within +/- 2 % from 20 Hz to 20KHz deteriorating to +/- 4 % at 100KHz.
