[time-nuts] Lucent KS-24361, aka HP/Symmetricom Z3812A

[Gregory Beat]

It has been five years (2014) since the Lucent GPSDO units, used in the cellular industry,  appeared on the surplus market.  The REF-0 units are still on the surplus market.

Dan Watson explored modifications (August 2015) for the REF-0 boxes to operate as a stand-alone GPSDO.  Including an updated GPS receiver to emulate the Oncore UT+ timing receiver.

Thomas Petig (Germany) built upon Dan’s work and explored the SCPI commands available on this KS-24361.

Has anyone taken “The Next Step”, replacing the Motorola Oncore 8-channel receiver (VP or UT+) with the Synergy Systems’ SSR-M8 Multi-GNSS Precision Timing Receiver?

This receiver features u-Blox LEA-M8 series miniature GNSS timing module (72-channel, SBAS enabled); a Motorola binary message emulation; and User Configurable PPS Output Rate.
