29. Compare the calculated calibration signal amplitude accuracy values to the verification test
limits in Table 17.
30. Close the NI 5693 session.
If the calibration signal amplitude accuracy verification procedure determines that the NI 5693
is outside of its limits, refer to
Worldwide Support and Services
for information about support
resources or service requests.

Note
Zero and calibrate the power sensor using the procedure in the
section prior to starting this procedure.
1.
Connect the RF source 1 to the power splitter input using the SMA (m)-to-SMA (m) cable.
2.
Connect power sensor A to channel A on the power meter and to the reference output of the
power splitter.
3.
Connect the other output of the power splitter to the NI 5693 RF IN connector using the
SMA (m)-to-SMA (m) adapter.
4.
Connect power sensor B to channel B on the power meter and to the NI 5693 RF OUT
connector using the SMA (f)-to-SMA (m) semi-rigid cable and the 6 dB attenuator.
