I couldn't find any information in the manuals as to why this resistor
is there. Why is it? To avoid ground loops?
561B (mentioned by keantoken) manual page 3-5 bottom left: "R183, which is about ten times the resistance of the braid of a 42-inch coax cable, cancels any ground loop current that may exist between the CAL OUT connector and some other instrument chassis." I didn't look in other manuals.
