@F6FLT: I'm agree with you, it is a good investment. Have you a link for the firmware ?

The firmware I installed is SDG2000_eevblog_23R7.ads. I don't know if there is an update since this time. It is available in a zip file, in reply #846 here (you will need an account and be logged to download):
https://www.eevblog.com/forum/testgear/the-siglent-sdg2042x-thread/825/

You must first update the Siglent with this software but it's not enough. You have then to delete the licence information. Only this alternative firmware allows telnet connection to do it.

I respect the author of the firmware who didn't provide the password but said it is easy to find. Yes, it's right, I guessed it. Remember your are on the "eevblog" site  :D.

Then see the "Guide for Dummies" in reply #353 here:
https://www.eevblog.com/forum/testgear/the-siglent-sdg2042x-thread/350/

You will have to connect a PC to the Siglent via ethernet (not USB) and execute some telnet line commands (Under Windows I used "putty" utility).

Thanks, I will try, not these days because I can't. In one forum, a guy said the signal above 100 MHz has a distorsion so I don't think it is the same hardware but it could help to have more than 40 Mhz. Strange, that Siglent limits their devices.

I didn't notice distorsion above 100 MHz up to 120 MHz. It's possible to exceed 120 Mhz by providing a sin(k*x) function as arbitrary waveform, with k=10 in practice but there is aliasing: we get a superposition of F and 150-F (for example 130 + 20 MHz), so in this case the signal is distorted but we are out of the specifications.
A possible reason that Siglent limits their devices (and possibly organize leaks for the hackers) is to create buzz from the (not rich) enthusiasts while the big companies pay the right price ?
