10. Disable the calibrator output.
11. Connect the calibrator test head to channel 1 of the PXIe-5113 and repeat steps 2 through
9 for each configuration listed in the
12. Disable the calibrator output.
Verifying 50
Ω
Bandwidth
Follow this procedure to verify the 50 Ω analog bandwidth accuracy of the PXIe-5113 by
generating a sine wave and comparing the amplitude measured by the PXIe-5113 to the
amplitude measured by the power sensor.
Before performing this procedure, complete the
calculate the
splitter balance
and
splitter loss
of your power splitter.
