Hi guys, I seem to recall that someone on this list mentioned that he's using a Thurlby-Tandar TF930 or 960 Frequency counter. As I'm considering to buy such a unit for some experiments at my workplace, I figured I'd better ask around here for some suggestions.
Has someone already used one of these gadgets in a computer-controlled fashion, with some luck using some Linux environment? Judging from the manual, I probably ccould hack some shell script to repeatedly perform frequency readings and write that to a file, but if someone already has done that I'd be much too lazy to reinvent the wheel... The actual setting I'd plan to use it in is to monitor some ring oscillators (frequency drift) and/or delay lines (output pulse length) sort-of-continuously over extended periods of time. I'd be interested in frequency drifts due to device aging and/or radiation effects, and as especially device aging tests can take quite some time (a few months each...), some sort of stability would be needed. This is not strictly a time-nuts application where one might chase the 10th digit, and I figure I probably could tolerate (and wouldn't even notice without cross-checking) an constant offset in frequency readings even of a few percent, but it would bite me quite a bit if the readings wander around too much when the input frequency doesn't... Any suggestions? best regards, Florian _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
