[time-nuts] Trimble "UCCM" GPSDO adevs

2017-02-23 Thread Mark Sims
Yes, if your TICC reference oscillator is of lowish quality you should run the TICC in time interval mode and it can analyze one device. To analyze/compare two devices with one TICC you really need a very high quality reference oscillator... I have a couple of FTS oscillators that have

Hi I agree with their premise that to be useful you need transportable clocks. I’m not quite sure that something the size (and weight) of a pickup truck is really transportable. Yes one can move it around (unlike a small mountain) …. Transporting something like that from here to Europe and

This is very, very cool, Mark. I've been concerned for a long time that people take way too seriously what you properly call "bogo-ADEV" that's self-generated from the GPSDO. Integrating a counter that compares against an external source is a huge win. But I want to remind everyone that as

I just added the capability of Heather to monitor and control a GPS device while simultaneously calculating ADEVs from an external time interval counter like the TAPR TICC (it can also work with the time interval analyzer only). This mode lets Heather calculate true adevs instead of

If your counter is showing up in the NI device tree, you should be pretty close to getting it working. I haven't used a 5328A, but I suspect the command you have shown above is sample code for a basic program, the actual HPIB command may just be a 'T'. On Thu, Feb 23, 2017 at 1:37 AM, James

Lady Heather has detected a GPS week rollover event... 10 seconds of consecutive years less than 2016. When this happens Heather adds 1024 weeks to the receiver date until it is past 2016. This can happen when Heather is connected to a receiver that is starting up and sending invalid dates

Perhaps something just went wonky in my setup but just noticed that the date that LH 5 (TSIP) is displaying with my Nortel is very wrong. Any idea how to correct. Could have happened after I did a cold reset a couple weeks ago. -=Bryan=- ___

Does anyone have experience using older HP equipment with the NI GPIB-ENET/1000 GPIB to ethernet box? Is this even possible with such an old piece of equipment? I'm very familiar with using SCPI commands over telnet but not so familiar with HPIB. So far I've installed the NI 488.2 software which
