Configure the power sensor with the following settings:
•
Power measurement: continuous average
•
Path selection: automatic
•
Averaging: automatic
•
Averaging resolution: 4 (0.001 dB)
•
Aperture: 20 ms
9.
Configure the signal generator to generate a sine waveform with the following
characteristics:
•
Frequency: the
Test Point Frequency
Power Splitter Characterization
table
•
Amplitude level: 2.0 dBm
10. Configure the power sensor to correct for the
Test Point Frequency
value using the power
sensor frequency correction function.
11. Wait 0.1 second for settling.
12. Use the power sensor to measure the power in dBm.
