Many thanks for all the replies. Nigel, thank you for the link. I did have this pdf, but was not reading it correctly.
It has been suggested that perhaps the counter main board was "set up" (modified) for a 12GHz channel 3. That would have required some mods to the actual main board, but I am not sure what they would be to check them out. The FW is 3703, so the counter is pretty current. I have a second 53132A with a 3.0GHz channel 3 installed which works properly. I will try some swapping of boards to see if the issue is with the new channel 3 board or with the new counter's main board.
