NI PXIe-5693 Calibration Procedure
Characterizing the RF Source Power (with Splitter and
Attenuator)
Note
Zero and calibrate the power sensor and define the power splitter reference
output using the procedures in the
Designating the Power Splitter Reference Output
and
Zeroing and Calibrating the Power Sensor
sections prior to starting this
procedure.
1.
Connect the RF source 1 output to the power splitter input using the SMA (m)-to-SMA (m)
cable.
2.
Connect power sensor A to the reference output of the power splitter.
3.
Connect power sensor B to the other output of the power splitter using the
SMA (f)-to-SMA (m) semi-rigid cable and the 6 dB attenuator. Figure 3 shows the
completed equipment setup.
