Hi All, First time post. Repairing 3 X 4032 units. Regards Gerald vk3gm

Hi Everyone. Sorry about the mixed posts, access now sorted. Regards Gerald VK3GM

There is some 4032 files here: https://xdevs.com/doc/Wavetek/

Thanks, Have that already. My initial posts are not in order. I managed to get options plugin sorted, autodetect. Just replacing SMD electros where needed. Regards Gerald VK3GM

Hi Gerald, It is a good idea to note all cards from all machines with their numbers and revisions. The Option Card from the picture is not a problem, you can put it in any unit you like, unless the

Repair tip for these units: Swap all SMD Electrolytics as long as they have the grey-ish black polarity marking. If they have a glossy dark black marking they are already new. The grey-ish are leaking

Hi Alan, have a look at the pics from a board adjacent to the one with the faulty cap. Both wire ends of the cap go into sockets, they are not soldered. On the left its the power distribution board,

Hi Martin, Wavetek had a very bad run with, in particular tantalum capacitors, the moulded ones. So, I'd suspect those in orange blocks, the ones marked 16V +22.? In the 3002 0 - 520 MHz sig-gen,

Hi Alan, but this shorted through capacitor is a ceramic one, according to the parts list. I find that very strange... As I said, the unit worked fine once I replaced the through cap by some wire, at

After an hour or so measuring around the power supply, following the diagram in the service manual, I ended up at the circuit where the suspect eletrolytic cap is. And indeed, it has a total short.

Hi Ulrich, Thanks for the feedback. Onto the second unit. Unit 1 complete, powers up and passes all tests/spec. 10MHz internal ref has aged, external 10MHz ref works well. ?1991 build. No. 1 CRT

Hi Everyone, Found swapped rf connection on added FEX RF PCB. Now have 4032 with FEX running. I had the impression with FEX you also get Spectrum analyser extension. To my dissatisfaction, no, only to

Hi Gerlad, if you could make a list of options (additional modules) this 4032 has installed, I can send you the wiring for the RF harness. Ulrich

Hi Ulrich, Just swapped options modules, now have fairly advanced 4032. option installed are as per photo, plus GSM. No analyser option or tracking unit. Interesting comment you made about wiring

Hi Ulrich, Looking at manual, section 12, Stabilock 4032 Lifeline, my host-mcu is at 6.10, would need 6.13 and up. I may copy all my EPROMS for safe keeping and share. There does not appear to be much

Hi Ulrich, Can you share your excel sheet, a pm is fine. vk3gm@.... Regards Gerald vk3gm

Hehe, no I meant the types of RF modules installed. Duplex and such? I do have a 4031 with almost all-in configuration including FEX. I am still searching for the correct analyzer option as mine is

Hi Ulrich, Not sure if the picture below tell you the modules fitted. That last module, slot 5 is quite different to both my other units.

Oops, Added photo.

Another wiring config. Non FEX units and no GSM.
