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 shows the 
completed equipment setup.
