13. Repeat steps 9 through 12 for each configuration in the
Power Splitter Characterization
table, recording each result as
splitter output 2 power
, where each configuration has a
corresponding value.
14. Disconnect the power sensor and 50 Ω BNC terminator (f) from splitter output 2 and
splitter output 1.
15. Connect the power sensor to splitter output 1.
16. Connect the 50 Ω BNC terminator (f) to splitter output 2.
The following figure illustrates the hardware setup.

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.
