Hi John
Thank you for your suggestion, however, the fault in the 8648B is not in the RF portion but in the uP display/control circuitry which is totally different between the 8920A and the 8648B.
I appreciate your input.

George,
Some of the boards in the 8648 are very similar to those in the 8920. The Component Level Information Packet Manual Part Number: 08920-90107, has schematics. It is (or was) on Keysight.com.

Hi Don
I now understand your email, having looked at the available HP manual, I will probe around the display connector and the RPG connector.
However I suspect that without component level information I will be unable to get very far. Every search comes back to the same document, HP part number 08648-90048 which as you are aware has no component level information.
Many thanks for your efforts
George G6HIG
