In Germany if you need spare parts there is absolutely nothing left, you can't even get the 49.9 ohm resistor anywhere, these days you have to order everything from somewhere abroad, it's a shame and you then wait for these parts for weeks, It's no fun anymore to repair any device. Just buy and use everything and throw it in the electronic waste.

Is that also the case in your countries? Or can you get parts better here, Mauser Elektronik has pretty much no idea where they get these parts from, but you don't really want to order everything for 20 euros or so much that you don't need in order to save on shipping do it.

Have you looked at the pictures, a super clean layout, but beware of something broken like mine is currently, then good advice is very expensive.

TurboTom:
My approach for initial fault finding would be to remove U70 (Hittite / Analog H1118) and to jumper pads 14 and 3 on the pcb with a wire as short as possible. If the output signal is re-established at the proper level, replace U70 and you should be ready to go.

The tricky part will be removal of U70 since it's got an exposed pad, the board appears to be at least a hybrid composition, maybe Rogers, and the "white" (RF) side of it isn't typically known for its rigidity... Traces are easily pulled off if the solder isn't completely liquefied. Lead-free solder that Siglent used for assembly doesn't simplify things either. You need a decent SMT rework setup and some experience to get it right. At least, I wouldn't approach the job with single-sided heating of the PCB, due to the multiple layers of copper inside.

I hope that the "dump switch" U70 has saved the rest of the circuitry!

All the best,
Thomas

Yes, I'll do that as soon as the 1118 is delivered. Mauser has withdrawn the order because only certain companies can order it but not on my Company  |O, I have now ordered it via Farnell. It should supposedly arrive tomorrow, if it is true, I will be surprised.

Soldering and unsoldering is no problem for me, hot air and very good flux, I do these and BGA almost every day, just don't drink coffee beforehand!

I'll do the connecting of the input and output after it's outside, I measured it again yesterday with the Speci, which comes out at the back with the 2.2V set (10-12µV), so to speak, nothing

As soon as I have the new one, I measured it without the IC and then with the new one back in, I'll report back.

markus_jlrb:
Dears,

I would not like to open a new thread, as my question is partially related to the SDG6kX device
in combination with the SSG3kX.

I would like to ask if someone of you had already tried to pass a IQ signal generated by the SDG6kX
to the internal ports available in the SSA3kX (without IQ HW option)?

See the internal SSG3kX pic's listed few postings above.
