f) Set the modulation source to internal.
g) Set the modulation phase deviation to 5 rad.
h) Set the modulation rate to 1 kHz.
i) Set the modulation waveform to Sine.
j) Turn on the modulation output switch Mod/on.
3. Configure the signal analyzer:
a) Set the center frequency to 1 GHz.
b) Set the span to 200 kHz.
c) Set the reference level to 0 dBm.
d) Set the input attenuation to 10 dB.
e) Set the resolution bandwidth to 1 kHz.
f) Set the video bandwidth to 1 kHz.
g) Set the sweep time method to accurate.
h) Select ØM analog demodulation.
4. Press Meas Setup  Auto Scale on the signal analyzer and read the results of the
demodulated signal in the ØM analog demodulation test interface of the signal analyzer.
Record the measurement results of (Pk - Pk) / 2 and Distortion.
Note: (Pk - Pk) / 2 represents the peak of the low frequency signal after ØM demodulation.
5. Calculate the Modulation Accuracy = |(Pk - Pk) / 2 - 5 rad|, Distortion = Distortion
Value. Then, compare the calculation results with the specifications.
