All voltage levels are fine and I have 5MHz as well as 15MHz on the

I have no idea where how the 10MHz is generated. I do not see any

I suspect the key to your issues are the FPGA error codes. It’s likely that a
lot of the “work” is done in the FPGA. If it is not setting up properly, you
will get all sorts of problems.
Try:
1) Unplug the memory chips and plug them back in. Sockets can have issues …
2) Look for tin

Hi
If you *need* portability, an internal oscillator is a good thing. If you want
to fire something up fast, an OCXO is not a good choice. That’s a bit of a
problem.
A few real choices:

The packaging for the previous generation of Lucent RFTG gear was a box with
no vent holes and lots of fins. It was anodized aluminum with that pale
metallic yellowish color.
SO, I just connected my third LTE-Lite unit.
By the time the software drivers were installed, and I selected U-center
to the new COMM port, it had a fix. Even with the survey LED still
blinking.
I looked at the GoogleEarth view, and the fix is within six feet of
where the antenna really is.
There has recently been comments on the COM port allocation in relation to the
LTE-Lite project which reminded me that I have seen an issue trying to run
multiple instances of the uCenter software in order to monitor/configure
multiple uBlox receivers at the same time. Unfortunately only one

Do not trust Google Earth data for any precision work. The mentioned six

Sorry. Couldn't resist.
I like the idea of having multiple GPSO's to compare with each other. If they

Hi
As has been mentioned, there are a variety of HP boxes, each with their own
pluses and minuses. Compared to a T Bolt:
1) They all are bigger
2) They all pull more power
3) None of them work with Lady Heather (which is a big deal to me)
4) None of them have coefficients you can modify

OK so it was not as hard as I thought getting all of teh screws out. The

Just started to trace out the 15 Mhz signal internal to the ref1. Top of
board side near oven and rs422 connector are the power amplifiers and

So will need to take the board out to trace further.

Best to remove the front panel and take it out the front. Still, it's tight

I think I have a flaw in my understanding of this.
How can something like an SR620 measure the ADEV of an oscillator, if the
oscillator is of a similar or better than the reference fed into the SR620?
I see plots of ADEV for hydrogen masers, but I can't understand how this
can be measured from
