7. Perform the following steps for each row listed in Table 17-4:
a.Set the synthesized sweeper amplitude to the value listed in the
Nominal Source Amplitude column in Table 17-4
b.Set the Mech Atten as indicated in the Attenuation column in Table
17-4
c.Set the Span as listed in the Span column of Table 17-4
d.Record the source amplitude, as measured by the power meter, in the
Power Meter Amplitude column of Table 17-4
e.On the signal analyzer, press Restart.
f.Wait for the signal analyzer to finish averaging.
g. Press Peak Search.
h. Record the signal amplitude, as measured by the analyzer in the
Measured Amplitude column of Table 17-4
i. Calculate the signal amplitude accuracy error using the following
equation, and record the results under the Amplitude Accuracy
Error column:
Amplitude Accuracy Error = Meas_amp − Power_meter
