Siglent SSG3000X and SSG5000X series RF Signal generators

Won't work...unfortunately  :-//

If you follow the traces around J1 and J2, you will find two two-way switches U18 and U22 that either link the RF signal internally (via C122, R40 Jumper, C124) or externally to J1 (output to the I/Q modulator module) and from J2 (input from the external I/Q modulator module) towards the AM modulator section. Without this module, the SSG3kX won't do I/Q modulation.

Hi...

After I was contacted by a forum member, I have now understood it and am of the opinion that this is indeed still a bug:
Screensaver function...
You set it to say 1min, then it actually runs - but not after a restart.
Even if you set the power-on state to "last", it does nothing.
According to the menu, the system then remembers that the screensaver was set from "off" to 1 minute, but it is no longer activated.
Only if you change it back to "off" and then again - and then it only works for the current "session", after a restart the screensaver is no longer executed as described above.

The H1118 was delivered just one day after ordering.

Apparently I burned the first IC while soldering it in, but I didn't use the second IC again with hot air but used it conventionally and so far everything is working as before.

The problem with soldering in and out is the circuit board, so much heat is drawn off via the circuit board that you can't actually solder it in here without a heating plate on the underside and I don't have a heating plate, all the other ICs do So far in my life I have only replaced it with hot air, but this... and at a maximum of 280 degrees, which this IC can handle according to the specifications, you don't really get very far when soldering in, even if the tin is included Its melting point is 185 degrees, the board eats it like nothing.

The main thing is that the generator is now running again inside, what more could you want.

But I don't want to remove or solder this IC again without bottom heat!

@TurboTom,

according to the UI, an external IQ signal could be enabled in the SSG3kX.

That's  what confusing me. But on the other hand no external IQ Input BNC
are available, but the case is already prepared for this purpose.

Btw the UM claim that external IQ modulation via a SDG6kX is possible, but
Siglent support decline this statement written in the manual.

Martin72:
The whole IQE story stands or falls on whether you have an IQE model.
This requires the board inside and the two BNC sockets on the rear panel.
If you don't have such a model, you probably don't need to think about it any further.
