5.
After the spectrum analyzer finishes a sweep, use Peak and the cursor function
to measure the maximum spurious signal (except harmonics) and record the
measurement result as A. Calculate the non-harmonic spurious signal (A-0dBm)
and judge whether it is within the specification range.
6.
Keep the output impedance of CH1 of DG1000Z at 50Ω. Set the output
waveform of CH1 as a sine waveform with 10MHz frequency, 0dBm amplitude
and 0V
DC
offset.
7.
Keep the reference level, input attenuation, resolution bandwidth, peak offset
and sweep mode of the spectrum analyzer as 10dBm, 20dB, 1kHz, 3dB and
single respectively. Set its start frequency to 0MHz and stop frequency to
50MHz.
8.
Press Sweep/Trig
Single to perform a sweep.
9.
After the spectrum analyzer finishes a sweep, use Peak and the cursor function
to measure the maximum spurious signal (except harmonics) and record the
measurement result as A. Calculate the non-harmonic spurious signal (A-0dBm)
and judge whether it is within the specification range.
10.
Keep the output impedance of CH1 of DG1000Z at 50Ω. Set the output
waveform of CH1 as a sine waveform with 20MHz frequency, 0dBm amplitude
and 0V
DC
offset.
11.
Keep the reference level, input attenuation, resolution bandwidth, peak offset
and sweep mode of the spectrum analyzer as 10dBm, 20dB, 1kHz, 3dB and
single respectively. Set its start frequency to 0MHz and stop frequency to
100MHz.
12.
Repeat steps 8 and 9.
13.
Keep the output impedance of CH1 of DG1000Z at 50Ω. Set the output
waveform of CH1 as a sine waveform with 30MHz frequency, 0dBm amplitude
and 0V
DC
offset.
