3. Set the signal generators:
Set the output frequency of Signal Generator A to 50 MHz; set the amplitude to -20 dBm.
Set the output frequency of Signal Generator B to 65 MHz; set the amplitude to 0 dBm.
4. Press Channel on the power meter and set the frequency of Channel A to 50 MHz.
Enable the output of Signal Generator A and disable the output of Signal Generator B. Observe
the measurement value of the power meter. Adjust the output amplitude of Signal Generator A
until the readout value of the power meter becomes -20 dBm.
5. Press Channel on the power meter and set the frequency of Channel A to 65 MHz.
Disable the output of Signal Generator A and enable the output of Signal Generator B. Observe
the measurement value of the power meter. Adjust the output amplitude of Signal Generator B
until the readout value of the power meter becomes 0 dBm.
6. Disconnect the power divider and power sensor; connect the power divider and spectrum
analyzer, as shown in Figure Figure 2-7 (b).
7. Enable the output of Signal Generator A and disable the output of Signal Generator B.
8. Configure the spectrum analyzer:
a) Set the center frequency to 50 MHz.
b) Set the span to 100 kHz.
c) Set the reference level to 0 dBm.
d) Set the input attenuation to 0 dB.
e) Set the resolution bandwidth to 1 kHz.
f) Set the sweep time mode to Auto; set the sweep time rule to Accuracy.
9. Press Single and wait for the instrument to finish a sweep. Press Peak to measure the current
peak, record the measurement result as A1.
10. Enable the outputs of the two signal generators. Press Single and wait for the instrument to
finish a sweep. Press Peak to measure the peak at 50 MHz, record the measurement result as
A2.
11. Delta = A1 - A2. Record the delta result.
