FWIW, I used to build and test Systron Donner 101s at their UK subsidiary in the early 70's. Nice little box!

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.
