Description
The SWPOUT command selects the sweep-related signal that is
available from connector J8 (labeled LO SWP|FAV OUTPUT) on the
rear panel.
FAV (frequency analog voltage) provides a voltage nominally
equal to 0.5 V/GHz of the tuned frequency when in
internal mixing.
FAVA (frequency analog voltage attenuated) provides a
voltage nominally equal to 0.25 V/GHz of the tuned
frequency when in internal mixing. For Agilent
8564E/EC and Agilent 8565E/EC only.
RAMP provides a 0 to 10 V ramp corresponding to the sweep
ramp that tunes the first local oscillator (LO). In
multiband sweeps, one sweep ramp is provided for each
frequency band.
When configured to use preselected external mixers, the 0.5 V/GHz
signal is automatically selected. The 0.5 V/GHz signal is increased to
1.5 V/GHz and the external mixer preselector DAC value is summed
with it before it is output. This means that with preselected external
mixers, the 0.5 V/GHz output provides a signal of approximately 1.5
V/GHz of LO frequency to control the mixer.
