Since the lowest sample rate contemplated (except for my $25 DATAQ) is 44 kHz, that's 20-25 microseconds maximum offset, even if you use different digitizers, once you've figured out the alignment (which you could do with a single sync pulse fed to all channels) _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
