The performance is about the same, I never noticed that one interface is faster than the other. The performance is probably more driven by the pea-brained microcontroller in the box. The 53131/2 are pretty well behaved boxes, I found them to be very reliable and easy program without too much fiddling. Sometimes GPIB equipment can be pretty badly behaved, but the 53132A is great. jeff _______________________________________________ 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.
