I'm going to build the Elenco AMFM108CK radio kit, and in the manual we can see several figures like this:
There is a capacitor between the function generator and the DUT.
So guess this is to block DC entering the generator when sending a signal into the middle of a circuit. Is this common, and a good way to protect the generator?
Full manual available here: https://www.elenco.com/wp-content/uploads/2017/10/AMFM-108CK_low-res-2.pdf
If you are using a high-end sig-gen, where you are sure that the signal has no DC component you could leave the capacitor out.
Hi all, I'm considering buying a SDG2042X any way of getting a copy of 17R5? Any help would be appreciated.

Available in Siglent web side 2.01.01.23R3 is most old.
I believe it is so that if someone have SDG with version what is below 2.01.01.17R5 then he need first update to 2.01.01.17R5
2.01.01.16R2
2.01.01.15R2
2.01.01.12R1
And as we know, after 2.01.01.17R5 or later then can not anymore go back to older versions than 2.01.01.17R5.
I have these old versions. Btw, these older versions are not packaged to .ZIP, they are .RAR
(I will send 2.01.01.17R5 to @tautech )

Found the issue to be U41 which is 3.0 Regulator AF7230M to be faulty. U41 supply 3.0V to external modulation ADC. Regulator has been replaced with alternative and issue is solved.
I own a SDG2042X from quite a few years, but some how today is the first time I needed to AM modulate with an external Signal. I just can't get it work. I have plugged External signal to Aux BNC with level of 12Vpp.

Have you tried modulating with a lower amplitude? According to the manual, an external modulation of +/-6Vpp corresponds to a depth of modulation of 100% (the maximum 120%).
+6V to -6V is 12Vpp, but also specifies that the expected modulation signal must not have DC offset. Thats something else to check. 0V - 12V would also be 12Vpp but violate the given constraint.

Would you mind going back to your first post and adding: Solved, it was a HW fault.
Do you have any idea why U41 may have failed ?

I really have no idea, I have been looking for quit some time. Scratching my head, is it a software issue or hardware issue ?
Anyone come across an issue where the frequency drifts when burst is enabled?
