Its before breakfast for me now, but you could set up a transmitter on a ISM frequency at 5 GHz or 60 GHz, where you have plenty of bandwidth (where plenty means 160 MHz or 2 GHz) and transmit your own clock signal. Either you roll your own by modifying some ham radio open source designs, or try

Hi, about getting time from the Internet to a clockwork: Have a look at the ESP8266, which you can get from china for as low as 4€ in the embodiment of a AMICA board: Its a controller with some GPIOs and WLAN enabled, freely programmable (Either with the ARDUINO IDE, or with a LUA or BASIC Fi

[time-nuts] HP5334A Option 010 replacement connector J8

2014-12-10 Thread Hendrik Dietrich
Hello list, same guy who direct-wired a STP2390C into a HP5334A earlier this year back here again. As a christmas holidays nano-project I made a little PCB to have a nice plug-in module instead of a snake nest. Today the boards arrived from the factory, and it was a lesson in "dont try to des

[time-nuts] KS-24361 Output spectrum to 100 MHz

2014-12-01 Thread Hendrik Dietrich
Hi List, here is my example spectrum taken with a Rigol 815, due to inpatience only up to 100 MHz. (I don't know if this was posted yet, but still then it would be a 2nd, 3rd example.) This shows what is meant by "clean 15, dirty 10 MHz." I always use insane pre-attenuation as every beginner

[time-nuts] RFTG-u REF 0 Z3812 as cleanup module for FEI5680A

2014-11-17 Thread Hendrik Dietrich
Hello List, having not looked at the spectra yet as I am confined to mobile phone instead of PC often, I had the idea to marry those two well-known devices to get a nice clean reference oscillator. I remember the spectrum of the FEI as not so nice, and the MTI sounds better. My understandin

Have a look at Bluetooth low energy. I am working with some nice Modules from Bluegiga (BLE112), they just announced a long-range version. Although they are already very conservative with power and will run for a while even with a button cell, a mercury switch (sorry) could trigger them upon mo

2014-05-21 Thread Hendrik Dietrich
Dear group, as I just yesterdays implanted a non-original OCXO (C-MAC STP2390C) into a recently ebayed counter, I wanted to share my experience: Swapping C8 to C100 position as per 5334B Service Manual (the B) is fine. J8, the connector for Option 010, is not in the 10811 layout as in the B.

Good morning Paul, First: I almost spilled my coffe as you bear a similar last name as a guy at a national research lab who does exactly such things :) Even when it makes your ECG preamplifier free for other things, I advise you to use another sensor and put a lot of decoding and interpretation t
