I'm not sure what the Z3801A uses for EFC range. Heather uses the EFC relative command to report the EFC setting. That command reports values from -100% to 100%. There is a command that reports the DAC input in counts, but nothing documented that shows volts/count.
Since the DAC is at -2V with a 99+% DAC setting, it looks like the DAC circuit has issues, or power supply problems. I think the DAC circuit is a 16 bit DAC with 4 more bits of resolution created by dithering the DAC inputs. _______________________________________________ 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.
