HP 70311A Clock Source

The HP 70311A and HP 70312A modules are synthesized clock sources designed to operate from 16 to 3300 MHz and 16 to 1500 MHz respectively. Both modules are part of the Hewlett-Packard Modular Measurement System (MMS) and may be used as a clock source for the HP 71600B Series of error performance analyzers and pattern generators, or any other MMS system with a suitable display (for example HP 70004A).

The clock source contains a non-volatile memory store which can be used to store
and recall 10 user-definable instrument setups.
