© National Instruments Corporation 15 NI PXI-5600 Calibration Procedure
15. Compare the result from step 14 to the specifications in Table 5 to
determine absolute accuracy.
16. Calculate the difference between the result from step 14 and PWR100.
17. Compare the result from step 16 to the specifications in Table 6 to
determine the relative accuracy.
18. Repeat steps 4 through 18 for the remaining calibration iterations for
this frequency, changing the signal generator amplitude and the
Reference Level and Mixer Level settings as listed in Table 4.
19. Repeat steps 4 through 19 for each of the test frequencies.
20. Call

You have completed the verification procedures for the NI PXI-5600.
Adjustment Procedures
If the results you obtained in the Verification Procedures section indicate
that the NI PXI-5600 does not meet its specifications, complete the
adjustment procedures described in this section.
Note Refer to the Connections section for a diagram of how to set up the test instruments
for these adjustment procedures.
Caution Always complete the adjustment procedures in the order specified in this
document. Varying the order of the procedures can cause inaccurate results.
