Powered-up on a Variac and all seems to be working ok. A friend sent me the Operating and Service Manual so will carry out performance tests next. Also need the correct scale for the 8620C, part number is 86222-90029.

Testing a 8620C Sweep Oscillator revealed a problem with the 86222A loading the Marker pulse. This was shorting out to an adjacent 0V pin in J2, an IDC (Insulation Displacement Connector) and has probably been a fault since first manufactured! This required a new wire and a cut track to bypass the problem. Operator's Checks and Performance Tests have now been completed satisfactorily.

All the 8407A & 8410C based Network Analyser System, including the 86222A, has now been Sold.
