Then I simply use Win Hyperterm (yuk) to capture the data to a file, and analyze that later. Works great with frequency counters, power meters etc. Have not tried SRQ. One interesting aspect about this "Abdul" card is that it has a built-in GPIB connector that plugs into the instrument directly. It's a curse and a blessing: it hangs out of your instrument without any mechanical support etc, and extends your instrument length, but at the same time it saves you a >$50 GPIB cable. BTW: the card is now being sold on Ebay again. One other factoid: the SMD chips seem to be soldered by hand, my card had a lot of solder flux on it. It's best to clean this off with Flux remover (Acetone type etc) for long term reliability. bye, Said _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
