Making Mixer Measurements (Option 089 Only)
High Dynamic Range Swept RF/IF Conversion Loss
NOTE
Because power meter calibration requires a longer sweep time, you may want
to reduce the number of points before pressing
to reduce the number of points before pressing

power meter calibration is finished, return the number of points to its original
value and the analyzer will automatically interpolate this calibration.

Once completed, the analyzer should display

Set the Analyzer to the RF Frequency Range
You can find the RF frequency range by using a simple calculation or using the mixer
measurement diagram on the analyzer display.
measurement diagram on the analyzer display.
Using the Calculation
Add the LO frequency to the IF frequency start and stop values. If using an LO frequency
of 1500 MHz, the RF start frequency would be 1.6 GHz (1500 + 100 MHz) and the stop
frequency would be 2.5 GHz (1500 + 1000 MHz).
of 1500 MHz, the RF start frequency would be 1.6 GHz (1500 + 100 MHz) and the stop
frequency would be 2.5 GHz (1500 + 1000 MHz).
