In an up converter measurement where the '%I$ ~~~~ softkey is selected, the notation
n
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 .RF );5' LO or I@+&%0 .
