Non-Input-Related Spurs (Residual Spurs) Verification
Table 12 shows the test limits.
Refer to Appendix A: Non-Input-Related Spurs Test Frequencies for the NI 5663 tuned
frequency and the equivalent RF frequency for the spurs.
1.
Connect the NI 5652 to the NI 5601 if it is not already connected.
2. Connect a 50 Ω termination to the NI 5601 RF IN and LO OUT connectors. Figure 6 shows
the completed equipment setup.

3. Create a new session for the NI 5663 using the niRFSA Initialize VI or the
niRFSA_init
function.
4. Perform an internal self-calibration on the NI 5622 using the niRFSA Self Cal VI or the
niRFSA_SelfCal
function.
