Hi Joe, In a case like this, where you're playing around with a GPSDO, you might want to log everything it has to output. Otherwise we play 20 questions about your antenna, your reception, your temperature, your cables, your neighbor, etc...
For these receivers I usually send a sys:stat? and diag:rosc:efc:abs? command every 30 seconds and log it to a file. Then if you notice anything odd happening in your 1PPS or 10 MHz performance, you just go back to the log file and have a look. It's only 5 MB per day. /tvb ----- Original Message ----- From: "Joseph Gray" <[email protected]> To: "Discussion of precise time and frequency measurement" <[email protected]> Sent: Monday, May 02, 2016 5:58 AM Subject: [time-nuts] Crazy PPS > After replacing the GPS module in Z3801A #2, I fired it up and let it > run.
