Nigel, thanks for the detailed response. I noticed the password option in the advanced menu as well. I ran it overnight locked to a 1-PPS feed and it seemed to stay witin +-200ns. Not spectacular, but within spec according to the older datasheets. I am mainly interested in the card as a timecode generator. However it looks like it might be more convenient to just feed the card an external 10mhz and not use the internal oscillator. Also, the RTC battery is toast, so it looks like I'll be replacing that at some point.
