4. On the analyzer, press:
Marker, More 1 of 2, Function
Marker Noise, Single
Marker, Delta
Sweep, 1 ms
Single
5. If the marker delta (∆ Mkr1) amplitude readout (the second line) is
not expressed as a percentage, subtract 1 from the marker delta (∆
Mkr1) amplitude (ignore the “X”) and multiply the result by 100 to
obtain the amplitude error in percent:
6. If the marker delta (∆ Mkr1) amplitude readout is expressed as a
percentage, subtract 100% from the marker delta (∆ Mkr1) amplitude
reading to obtain the amplitude error in percent:
7. Record the Amplitude Error as Test Record entry 1 in the
performance verification test record.
