Hi You can do a lot better than 5 ns these days if you want to spend some money. Some low(er) cost alternatives: 5335 counter running GPIB. The counter should be below $150 and it should get you to 1 ns or so. 5334 counter also running GPIB. A bit smaller / cheaper - should be around 2 ns.

Hello Frank, I appreciate the reply. The version of TimeLab that I am using is latest I guess based on the info in the help box. But I was running TimeLab with this same Prologix converter a couple years ago. Maybe I need to find an old version of TimeLab. I didn't realize there was a conflic

Hello, I'm currently working on the small DMTD system. The mixer modules and DDS are working, but the noise floor is still more than an order of magnitude higher than published in W. Riley's paper. Also, I'm having troubles to get the PICTIC's working. For the time being, I'm running the mixer

Check the DIP switch on the back of the 5370B to see if it's in talk-only mode. (Which is fine, but you'd need to use the Talk-Only selection on the Acquire menu, rather than the 5370-specific driver.) -- john, KE5FX Miles Design LLC > -Original Message- > From: time-nuts-boun...@febo.co

I love that title, nothing Atomic about it but the Marketing types love it. What I am looking for is a way to display Local Time (MST) and Zulu (GMT) time in a small (6" X 8" or similar) package. There must be two displays and both lock up to NBS. Has anyone seen such a thing ? Thanks, Dick

It will work. NTP has clock drivers for t-bolts. The name is "pasiside" or something like that. Find it in the drivers folder in the NTP reference distribution. Have you tried to see if two processes can read from the same serial port. I think they can. Normally it is bad idea. It would not
