USB RTL SDR 28.8 MHz Reference: VCXO | SimonsDialogs

One of the shortcomings of the USB RTL SDR devices is the build-in oscillator. It is actually very stable and sufficient for all kinds of everyday uses, but I am using these SDR devices for narrowband applications, with down-converted microwave signals.

DIY rubidium clock construction - Stack Exchange

If it's a 10 MHz square wave, just about any digital system will do. Ignacio's suggestion of directly clocking a microcontroller is a good one. You could also divide down the 10 MHz clock to 1 kHz and connected it to an MCU's external interrupt pin. One interrupt per millisecond should be easy to handle without any perceptible delay. (For that matter, so would one interrupt per second.)

87Rb Stratum 1 NTP Server – HARDWARE – Delta²

2015-03-08· First operative test of the RB Stratum 1 Server Following Poul-Henning Kamp project to modify a 4501 router to build a Stratum 1 NTP server, i've decided to build my own using instead a Rubidium Frequency standard source of 10 Mhz to clock the Elan processor inside the Soekris. . It requires some hardware…

Rubidium Clock | Audiogon Discussion Forum

2016-10-12· I have a G-Os Rubidium clock and it makes a pretty big difference in the quality of the sound - I agree with Randy above. The amount of change you hear is system-, room-, music- and listener- dependent, however.

Building a bench 10MHz reference: part 1 - Whatever

Many electronics test equipment need an accurate time base. Most often, it's build on a 10MHz base. For quite a while now, I have a used rubidium frequency and time reference (Efratom Model LPRO-101) waiting for a nice enclosure.

Frequency standards, GPS-synchronized, stand-alone, and ...

Optional outputs include 1,5 and 10 MHz outputs for metrology purposes, E1/T1 clock and data outputs for telecom and 13 MHz output for radio base station test. An external 1-pps disciplining input is another option. The ultra-stable, built-in Rubidium atomic clock oscillator offers excellent frequency and time stability, whether in GPS-disciplined mode, or in hold-over mode. Configurable ...
