c) Set the reference level to 10 dBm.
d) Set the input attenuation to 20 dB.
e) Set the resolution bandwidth to 30 Hz.
f) Set the video bandwidth to 10 Hz.
g) Set the sweep time method to accurate.
Note: Modify the center frequency of the signal analyzer accordingly each time the output
frequency of DSG800 is changed (the center frequency of the signal analyzer corresponds to
output frequency of DSG800).
4. Press Single and wait for the instrument to finish a sweep; press Peak Search to find the
maximum peak. Then, press Marker  Delta to set the cursor type to Delta. Set the center
frequency to 2 × F0, press Single and wait for the instrument to finish a sweep; press Peak
Search and record the delta result A1.
5. Calculate the Second Harmonic Distortion = Delta A1 and compare the calculation result
with the specification.
6. Press Mode Preset to reset the signal analyzer to the factory setting. Set the output
amplitude of DSG800 in step 2 to 10 dBm.
7. Configure the signal analyzer: set the input attenuation to 30 dB, set the reference level to 20
dBm and the settings of the other parameters are the same with those in step 3.
8. Repeat steps 2 to 5 to measure the second harmonic distortion when the output amplitude of
DSG800 is 10 dBm and record the result.
