[time-nuts] 8713C Network Analyzer Circuits

[Martyn Smith]

Hello,

Has anyone out there circuit diagrams for a HP8713C network analyzer?

The generate port is fine, but the transmission or RF IN port is faulty
below about 1.5 GHz.  It's response is all over the place.  Above 1.5 GHz it
seems to be fine.

I suspect the A5 receiver especially the RF input circuitry.

Any help would be much appreciated.

Regards

Martyn
