Agilent 8719ES, 8720ES, and 8722ES Option 089

Option 089 adds frequency offset mode, allowing
the receiver to be offset from the source frequency.
This allows direct conversion loss measurement of
mixers without need for a reference mixer. RF and
IF frequencies must be within the specified operat-
ing range of the instrument. This test set modifica-
tion adds an internal reference channel switch and
deletes the reference channel output. Firmware
guides the user through the test setup. When not
in frequency offset mode, the system operates as
a standard system and meets standard instrument
specifications.
