Please help me w/ a connector for my Rubidium EFRATOM FRS - EEVblog

Hello everybody, I'm the proud owner of a Rubidium 10MHz reference BALL-EFRATOM FRS . All nice and dandy, except for the ridiculous connector, a unholy bastard child between a DB15 and a coaxial connector, that has the designation: Cannon DAM11W1S I found some on the usual suspects sites, but unfortunately got lost into the ordering, it seems that each and every part must be ordered ...

KA7OEI - 10 MHz Rubidium Reference

Top Left: Inside the enclosure containing the 10 MHz Rubidium frequency reference. The Efratom LPRO-101 unit is partially visible in the background, mounted to the lid. The LM2577-12 19 volt up-converter can be seen soldered to the circuit board mounted to the wall of the box. A closer view of the voltage converter may be found here.

Rubidium Frequency Standard Repair | Hackaday.io

Starting with the EFRATOM PRFS-102 module, it is a pretty basic case, likely a generic one and put together by EFRATOM. The front panel has isolated BNC connectors for sinusoidal 10Mhz and 5Mhz outputs, and a TTL output with selectable frequency. A rotory switch selects between 1, 5 and 10Mhz.

PRS10 - Rubidium Frequency Standard

The interface connector and device form-factor are compatible with Efratom's Model FRS rubidium frequency standard. In its default configuration, the PRS10 uses pins #4 and #7 for the RS-232 interface to provide a complete set of systems diagnostics and control. Internal hardware jumpers allow these pins to be configured as analog outputs to ...

A homebrew rubidium oscillator clock - vaxman.de

The rubidium oscillator: The LRPO-101 rubidium oscillator is a completely self contained unit requiring only minimal external circuitry to be used in a generator/counter/clock circuit. Since the device gets quite hot it is important to mount it onto a heat sink or metal frame to get rid of the excess heat (read the respective section of the ...

Rubidium Frequency Standard ... from the Bay

The current then reduces to less than 500 mA, when the cavity is heated. (The lcd draws approx 100 mA). After some minutes, the lamp voltage reaches its final value of approx. 8 V (depends on age of device, some others show 6 V) and the bite goes low, indicating a "locked" status. With the maximum gate time of 100 s, we could not measure any ...
