Figure 2-37 Connections for a Mixer RF Feedthrough Measurement
8. Connect the external LO source to the mixer's LO port.
9. The measurement results show the mixer's RF feedthrough.
NOTE You may see spurious responses on the analyzer trace due to interference caused by LO to IF
leakage in the mixer. This can be reduced with averaging or by reducing the IF bandwidth.
