Amplitude Accuracy at 50 MHz
Procedure
h. Record the signal amplitude, as measured by the analyzer in the
Measured Amplitude column of Table 5-1
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
