Re: [time-nuts] Pulse generator recommendation
A Systron-Donner / Datapulse 101 or 101A is an old, but well performing pulse generator. Most pulse generators are not particularly precise, but many have an External Trigger function that can be connected to a precise timing source. I'm doing exactly that, using a crystal oscillator at 1 MHz and a set of Tek DD501s to simolate LORAN-A. I can easily set 40,000 uS to 1 uS. -John = All, I've been wanting to buy an older pulse generator, but want an accurate one, and probably one that I can connect to my GPSDO. I would like one settable to 10 nS, but don't want it variable to there, but switched between the different pulse rates. I looked at the older HP generators, and they look to have slide pots to control everything, including the time, and that killed them for me. I also looked at EH and Phillips/Fluke, but am unsure on what would be the best for what I'm looking for (certainly not new). Do any here have any thoughts on this, or what to look for?

Hi Will: The Stanford Research DG535 may be what you're looking for. See: http://www.prc68.com/I/TandFTE.shtml#DG535 seconds to picoseconds stability, external 10 MHz input.

Re: [time-nuts] Pulse generator recommendation
FWIW, I used to build and test Systron Donner 101s at their UK subsidiary in the early 70's. Nice little box!
