The HP 11729C creates a series of comb line frequencies based on a
640 MHz reference. These comb lines have specified band pass filters
centered on multiples of 640 MHz up to a 17.28 GHz comb line. If non-
standard filters are configured in the HP 11729C, they can be specified
in the System Configuration Table under 11729C Specs. The 640 MHz
reference can be provided externally or internally (self oscillation). Self
oscillation mode is an unspecified reference source without voltage control.
Typically the HP 11729C uses the specified 640 MHz output of the
HP 8662A Option 003 or the HP 8663A Option 003 as a reference for
the comb line generator. The HP 8662A/63A used with the HP 11729C
provides a low noise, specified microwave VCO reference.
HP-IB address switches are located on the rear of the HP 11729C and are
typically set to 06 (706).
