Hi "anonymous", the 53132A only does that for a couple of nanoseconds. Then it jumps to a stupid value such as: 0.004 us -0.002 us 0.999,999,993 s It get's even better when the counter decides it doesn't have enough resolution in frequency mode: 2,3** u Absolutely horrible to parse, these guys should have heard of scientific notation. Not sure who programmed that unit, or if there is a firmware upgrade that gives proper numbers. bye, Said In a message dated 12/13/2012 15:07:50 Pacific Standard Time, timen...@triplespark.net writes:
Counters like the Agilent 53230 actually WILL output negative delays in this case as long as the delta is still small. This is a quite useful feature in such cases... _______________________________________________ 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.
