While I had the 5372a apart today to replace the battery, I noticed that there is an SMA for channel C on the events board and diagram showing a cable from there to the front panel.

This suggests to me that the upgrade is a cable and a key, jumper, or memory setting.

Anyone ever done the upgrade?

Hi Bob,

There is also the A20 board for the C-channel consisting on a series of
attenuator, amplifiers/limiters and a divide by 4 before reaching that
SMA connector. You then flip the option switching on the motherboard.

I got the C-channel on mine, but you should be looking into
05372-90016.pdf which is the service manual, chapter 12.

If you have a replacement board that does the same operation, you can
enable the C-channel without too much effort as you install it.

Cheers,
Magnus

According to the service manual, the upgrade kit contains:

05372-60020	C-Channel Board
05372-60224	Front panel cable (semi-rigid)
[8 more lines of mechanics and cables]
