Time and Frequency Measurement

I maintain several high-precision Hewlett-Packard Z3801A ovenized quartz oscillators for Time & Frequency Measurement.
These units use a double oven precision quartz oscillator which is locked to GPS for long term stability.

Relevant data is gathered from these units continuously using the GPSCon Software package, which you can see here:
