Designating the Power Splitter Reference Output
Designate one of the two outputs of the power splitter as the reference output. Consistently use
the same output as the reference output throughout the characterization and verification
procedures.
Zeroing and Calibrating the Power Sensor
1.
Connect channel A of the power meter to power sensor A.
2.
Connect channel B of the power meter to power sensor B.
3.
Zero and calibrate the power sensors using the built-in functions in the power meter.
Characterizing the RF Source 1 Power (Direct)
Note
Zero and calibrate the power sensor using the procedure in the
section prior to starting this procedure.
1.
Connect the RF source 1 output directly to the power sensor B input.
2.
Connect power sensor B to channel B of the power meter. Figure 1 shows the completed
equipment setup.
