I've obtained bare Wavetek 1175 Benchmark scalar analyzer without any probe and manual.
The problem was in power supply, now is ok, and problems persist without probes ( for Ch A and Ch B) and manual.
Wavetek description for probe is: Power sensor with dual balanced, zero bias, low barrier schottky diodes.
I cannot find original probes, but I will make probe, I have some experience with GHz milivoltmeter probes (HP3406A , TF2603 Marconi).
System have message : Absent probe, and probes is detected with 3 pins of microcontroller 87c196 on AD board.
I need service manual or the schematic diagram for original Wavetek probe.
Any help and advice is welcome.
