[Test-Equipment] Does my 141T have a terminal illness?

[Gary Schafer]

Hi Carl,

Did you change RF modules? Some of the modules route the scan trigger
through the connectors on the back and some don't. For those that route the
trigger through the connectors you need to have in place the
jumper/terminator on the back. If you don't have one you can make up a
single wire jumper for the proper line to do the job.  It does sound like a
trigger problem.

By the way, without the jumper sometimes the trigger will still work and
sometimes it won't if using a module that requires the jumper/terminator.
