Hi At least according to page 20 in:
https://www.thinksrs.com/downloads/pdfs/manuals/PRS10m.pdf the “raw” PPS output from the PRS-10 is just a CMOS gate output. There is nothing suggesting it is designed to drive a 50 ohm load or a coax cable. Page 59 suggests that the “boardlet” does nothing but pass the signal to the connector on the board. Best guess: It’s doing what it’s supposed to, but not quite what you expected it to do.
