MULTIPLE SOURCE
CONTROL
The Multiple Source Control mode permits independent control of the
37XXXC source, receiver, and an external ANRITSU synthesizer
(67XXB, 68XXXB), without the need of an external controller (Figure
8-27).
Operation in this mode requires Option 11. Removing the reference
loop lets you isolate the receiver from the source. This permits testing
of frequency converters such as mixers.
The software lets the frequency ranges and output powers of the two
sources be specified. A frequency sweep can comprise up to five sepa-
rate bands, each with independent source and receiver settings for
convenient testing of frequency translation devices such as mixers. Up
to five sub-bands (harmonics) can be tested in one sweep.
Control Formula
Multiple Source control is specified as a displayed frequency range
partitioned into from one-to-five consecutive bands. For each band
Source 1, Source 2, and receiver frequencies may be interdependently
specified per the formula:
