Making Mixer Measurements (Option 089 Only)
Isolation Example Measurements
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.
Figure 2-38 Example Mixer RF Feedthrough Measurement
You can measure the IF to RF isolation in a similar manner, but with the following
modifications:
• Use the analyzer source as the IF signal drive.
• View the leakage signal at the RF port.
