15. Repeat steps 5 to 14 for all frequencies in Table 10.
16. Close the NI 5601 session using the niRFSA Close VI or the
niRFSA_close
function.
LO Output Power Verification
1. Connect the RF source to the power splitter input through the 3.5 mm-to-3.5 mm cable.
2. Connect the power splitter reference output to power sensor A.
3. Connect a 50 Ω terminator to the NI 5601 IF OUT connector.
4. Connect the other power splitter output to the NI 5601 LO IN connector through the
3.5 mm-to-3.5 mm adapter.
