Bob,
You are correct. I am using HP 5386A. And its only HP counter I have. I
set Gate time equal to 10sec. May be this gate time is an issue ? The
other settings is .1s, and 1s.
Meantime, I did switch ref signal source from Trimble TB to Oscilloquarz
8663-SX OCXO and connected MV89A to
Hi
*IF* I’m understanding you correctly, you are measuring this data with an HP
5386.
That’s only a 4 ns counter. I agree with Tom that there is something weird in
your setup, but that
still does not help the basic limit of the counter’s resolution. You will need
to be out around 1,000

Hi
You *could* do other things. Some form of switched attenuator is still the best
bet.

Absolutely a good answer. You could mess with lots of things. But the fact
is they are pretty much a mess. You have to linearize and right size etc.
So why mess with a great answer?

Thees units were made for the phone company, and phone companies
are big on hot-swapping modules. The shorter pins are shortened
to make sure that their circuit doesn't make contact until the
longer pins have made contact. Don't fix them!

Hi Ulli,
I heard some comments that the short jumper cable between the two units
would make an intermittent connection. You will notice that some of the
pins in the connector are shorter than the others and hopefully that is the
problem. I don't know if the plugs are wired 1 to 1, 2 to 2 and so
Sounds like very poorly to me...

Hi
I think that looks about as good as your counter can do. The slope down at
the start is the resolution of the counter. The slope up on the right is the
actual stability of
the oscillator.

Ok, when the interconnect cable goes out, the boxes simply do not boot up or
they boot to some strange pattern of LED’s. I have not seen the 15 pin cable

The traditional approach was to seal the unit up at the base. You
then baked it out (possibly at 125C) for some period of time (maybe 24
to 48 hours). After that you sealed off the magic hole in the package.
In some cases there was indeed a magic pot under the solder hole that

somewhat better manuals, the instruments are still not repairable by the

Though, Ulrich's program is still showing no more than two satellites.

Typically the pins are two or three lengths.
The longest pins are ground, the next are power, then signal pins. Quite often
used for things that are hot swapped. Take a look at a USB cable for example.

I’m not sure I can be of much help. I typically run several dozen serial ports

3) Get the drivers straight from FTDI

If its really number of USB devices, directly connected to the PC, then
it could be issue with overload of 5V bus on USB hub. It has certain
limitation.
As a workaround, you could try to use external USB hub with its own PSU.
