NI PXIe-5601 Calibration Procedure
16. Compare the
Absolute Gain Accuracy
to the verification test limits in Table 7.
17. Repeat steps 8 to 16 for all the settings in Tables 2 and 3.
Note
NI recommends keeping your RF signal generator enabled when repeating
steps unless making a connection change. Keeping the signal generator enabled
reduces the wear on the RF signal generator relays. After making a connection
change and enabling your generator, wait 5 seconds for the system to settle.
18. Close the NI 5601 session using the niRFSA Close VI or the
niRFSA_close
function.
