Perform the High Dynamic Range Measurement

1. Return the analyzer to the IF frequency range. Press
.
G/n
2. Make the connections shown in
3. Set the LO source to the desired CW frequency of 1500 MHz and power level to 13 dBm.

4. Set the analyzers LO frequency to match the frequency of the LO source by pressing:
System INSTRUMENT MODE
FREQUENCY: CW
5. To select the converter type and low-side LO measurement configuration, press:
RETURN DOWN CONVERTER
In this low-side LO, down converter measurement, the analyzer's source frequency
range will be offset higher than the receiver frequency range. The source frequency
range can be determined from the following equation:
receiver frequency range (100 – 1000 MHz) + LO frequency (1500 MHz) = 1.6 − 2.5 GHz
