17. Press MARKER A. Step the frequency synthesizer output
amplitude from + 10
to -80
in 10
steps, noting
the MARKER A amplitude (a negative value) at each step and
recording it in column 2 of
5-2. Allow several sweeps after
each step for the video filtered trace to reach its final amplitude.
18. Subtract the value in column 1 from the value in column 2 for
each setting to find the fidelity error.
19. Subtract the greatest negative fidelity error from the greatest
positive fidelity error for calibrated amplitude steps from -10
to -70
The result should be
20. Subtract the greatest negative fidelity error from the greatest
positive fidelity error for calibrated amplitude steps from -10
to -90
The result should be
5-l.
