24. Disconnect the 50 Ω BNC terminator (f) from splitter output 2. Refer to the remaining
assembly as the
power sensor assembly
.
Note
Do not disassemble the power sensor assembly. The power splitter
amplitude balance and loss characterization is invalid if the power sensor
assembly has been disassembled.
The power sensor assembly will be used in the following procedures:
•
Verifying 50 Ω Bandwidth
Verification
The performance verification procedures assume that adequate traceable uncertainties are
available for the calibration references.
Verification of the PXIe-5113 is complete only after you have successfully completed all tests
in this section using the
As-Found Limits
.
Refer to the following for the names, locations, and functions of the PXIe-5113 front panel
