17. Configure the signal generator to generate a sine waveform with the following
characteristics:
•
Frequency: the
Test Point Frequency
value from the
Power Splitter Characterization
table
•
Amplitude level: 2.0 dBm
18. Configure the power sensor to correct for the
Test Point Frequency
value using the power
sensor frequency correction function.
19. Wait 0.1 second for settling.
20. Use the power sensor to measure the power in dBm.
21. Repeat steps 17 through 20 for each configuration in the
Power Splitter Characterization
table, recording each result as
splitter output 1 power
, where each configuration has a
corresponding value.
22. Calculate the splitter balance for each frequency point using the following equation:
splitter balance
=
splitter output 2 power
-
splitter output 1 power
23. Calculate the splitter loss for each frequency point using the following equation:
splitter loss
=
signal generator amplitude level
-
splitter output 2 power
