I see this on the TSC 5120 but not the 5110. Same for you? When in "single DDS" mode the 5110 phase is absolute. But when in the "dual DDS" mode the raw phase output is scaled by "B/A frequency", which is displayed at the lower right side of the screen. I don't recall this value changing over time so I'm curious about your fcounter comments.
I only have the 5120 as a reference point, and it doesn't have the single vs. dual mode or show the frequency scaling.
I was referring to the frequency counter screen on the 5120, which you can dump via ethernet. I wrote a program to poll the box, capture the dump, and parse the data into a logfile.
The fcounter screens (for 1, 10, 100, 1000 second averaging) seem to update every few seconds. I usually log every ten seconds and that seems to give reliable results.
