Making Mixer Measurements (Option 089 Only)
Measurement Considerations
Figure 2-7 Down Converter Port Connections
• In an up converter measurement where the softkey is selected, the
notation on the setup diagram indicates that the analyzer's source frequency is labeled
IF, connecting to the mixer IF port, and the analyzer's receiver frequency is labeled RF,
connecting to the mixer RF port.
Because the RF frequency can be greater or less than the set LO frequency in this type
of measurement, you can select either or .

Frequency Offset Mode Operation This mode of operation allows you to offset the analyzer's source by a fixed value, above or
below the analyzer's receiver. That is, this allows you to use a device input freq uency range
that is different from the receiver input frequency range.
