[time-nuts] HP 105B Problem?

[gsteinba52 at aol.com]

My impression is that the 10811 update to the 105A/B is just the OCXO. HP apparently decided to standardize on one oscillator for frequency units and therefore created the three-board assembly (one to condition power, one to divide and condition the signal, one to hold everthing together) as a 'plug compatible' drop-in replacement unit for the older 5MHz oscillators (similar size, same push-on connectors, same alignment of the coarse freq control).

This 10811 assembly is also used in the Cesium standards.

Specs for output: Voltage levels: => 1V rms into 50 ohms.
