2 Lucent/Symmetricom Time & Frequency Modules 1 OMR X72 Rubidium 1 OMQ LPN OCXO

Description

This Auction is for two Lucent Symmetricom Time and Frequency Modules. One is rubidium and one is quartz.
The auction includes one of each module detailed below:
1. One Lucent OMR  S3:05 408645968 Symmetricom 108830-002 OMR rev N which is built around a Symmetricom X72 Programable Rubidium Oscillator.  The X72 rubidium oscillator output is 10MHz and the OMR module front panel output is 15MHz but could be modified to 10MHz.
There is a small dent on the X72, but does not effect performance (see photos).
2. One Lucent OMQ
S3:07 40865984
Symmetricom 108830-001 OMQ rev N which is built around a Symmetricom 106824-001 5MHz Low Phase Noise Digital EFC Ovenized Quartz Oscillator. The OMQ front panel output is 15Mhz but could be modified to 5 or perhaps 10 MHz
With a bit of work t
his pair would make nice Time and Frequency Standard/Reference. Or applications in other Time and Frequency hobbyist/experimenter projects.
Both cards utilize the same circuit board with almost identical component population.
I have marked the rows of pin to apply the required 15VDC, the fuses make tracing the power easy, and by tracing pin-outs it should be fairly simple to discipline.
My guess is these are disciplined to 1PPS, but that is just an educated guess. If so the addition of a GNSS module would complete the system.
If I find more information I will list it.
Over the years I have not seen much documentation on these Lucent OMI Time and Frequency Modules, and would be interested in any information anyone would share. My best guess looking at the boards, they appear have some interesting features, such as Power regulation, Buffer Amplifiers,
ability to lock to an external reference, 1PPS 10MHz (which would allow the addition of a GNSS Timing Module),
and the circuitry to convert the 10MHz to 15MHz output on the rubidium board which should be easy to by pass to provide two 10MHz outputs from the front panel. And 5MHz to 15MHz on the Quartz board. I have a number of these and would entertain a quantity purchase. Please check my other Time and Frequency auctions.

Our Company and Philosophy:
We Want your purchase to exceed your expectations.
The first question is whether this is the right piece of equipment to meet your needs,

another eBay seller, dealer, or manufacturer who has exactly what you are looking
.
The second question is condition. In this case "As Is" "No Returns". We have done our best to describe the issues, but please ask questions before you bid.
We view others with a passion for Test and Measurement as part of a very special community whether a hobbyist or Noble Price level Physicist and will do our very best to treat any buyer the way we would like to be treated ourselves. All we ask is you treat us fairly and we will always go the extra mile even beyond eBays requirements and our stated warranty to take care of any legitimate issue - whether a performance issue or simply not the instrument that best serves your needs. Again we encourage you to contact us before you bid with any question on the capabilities, condition, and perhaps most importantly if it is the right product to meet your specific needs.
