They were a competitor to minicircuits and others. Tried to win by being very
inexpensive.

I'm drawing a blank on a blank on a pile of R&K devices I just found in a few
boxes I had forgotten about. They look like relays or filters (2x4 pin,
non-hermetic metal case, 10x10x20mm), internally it looks like an active device
with a balun on both sides under silicone. I remember R&K, but I
Have you tried terminating it with 50ohms? That was the trick for mine.

Hi All,
I got a Trimble Thunderbold from Ebay and I am having trouble triggering the
HP 53131A. The 1PPS output shows a 10us pulse of 1 Volt into a high
impedance probe. This seems low to me. Should it be 5 volts? Maybe the
output 74AC04 is toast?

Hi Bill,
You're right there are two US stations on the HF band, WWV and WWVH. I was

of WWVH per se. In either case neither WWV or WWVH were not there in any
recognizable strength.

I've moved my 5370 over to a UPS, along with the Prologix and the

I'm not familiar with any GPIB bugs on the 5370A, but I moved your code over
to C and ran it on my 5370B via a GPIB-LAN adapter. The test app failed
after ~6 hours with a Winsock timeout error. I'm thinking that was caused
by a power glitch, though, because I actually had to power-cycle the count
Chuck,
Could I get a copy of the yellow sheets change pages?

Hi Scott,
I have the last manual made, it was prefix 1908A, and there are yellow sheets
up to 2816A.
My copy was bought directly from HP, in the late 1980's(IIRC).
