Hi all,
Thank you so much for your inputs. Here more details on what i am looking for:
1) 4 channel
3) 350Mhz at least + probes with same or higher BW
4) digital decoding (I2C, UART, SPI CAN)
5) FFT ( I do like the dedicated RF channel of the Teks...)
6) 10 inch screen will be nice
7) LAN interface
Well, that's not really a lot more information and still leaves you with scopes from some $2k to > $15'000.
FFT is standard on pretty much every scope, but there are differences in resolution capability (oh, and that Tek dedicated RF channel is nothing more than a separate input for scope FFT) and processing speed.
Decoding for I2C, UART, SPI and CAN has also been more or less standard (either included or as option) except for a few really low cost scopes.
Probes, well, pretty much all scopes come with only passive probes which don't go over 600MHz, and which in reality are only good for signals up to 250MHz-300Mhz. Anything better will be at extra cost, and very likely be expensive.
You still haven't told us the important bit, which is what you want to do with the scope and what your budget is.
2 channels waveform generator
As Tautech wrote, get a standalone one. It's a lot more cost effective and you get a lot more for your money than with any of the buildings-in AWGs.
9) affordable compatible current probe
As a general rule, current probes from scope manufacturers are not cheap, and what is áffordable'to you depends on how much you want to spend (which goes back to the question about your budget).
I have a Siglent sds1102 but not really happy with the speed and user interface, I guess the new 5000 series is much better...
SDS1102 what (There's a whole decade of various SDS1102xxx scope models)? CL? CML? CNL? CFL?
In any case, as Tautech said if it's one of the older scopes then a lot has happened since then, and the current Siglent scopes have improved a lot since then.
