You gotta love...

... your wife, obviously. But you gotta love her just that little bit more when she gives you permission to buy a scope Oh happy days.

I’m thinking Siglent SDS1104x-e. Should be more than adequate for my purposes for quite some time and not overly expensive.

Hi Frank, That's a good point, if 4-chan use is going to be low (which it often is), if the cost difference is high, a 2-chan 'scope could be better value for money. Even protocol decoding sometimes isn…

You will enjoy your new scope I am sure. I have the Siglent SDS1102 CML which is a 2 channel version of that scope as well as a Rigol DS1054Z upgraded to 100 MHz which is an entry level 4 channel scope…

I think my first stop will be "how not to blow up your oscilloscope"! And after that, I expect there will be some videos/screenshots of debugging the power supply I'm building. I did think about the 2…

That's great news!
It looks like a nice modern 'scope, so you've got the flexible trigger types, lots of memory, USB for screenshots, and future expansion option capability. Also it has a large decent res screen + clean-looking layout with the buttons and soft-buttons, which is great for usability.

I have the Siglent SDS1102 CML which is a 2 channel version of that scope as well as a Rigol DS1054Z upgraded to 100 MHz which is an entry level 4 channel scope I bought used. My Keysight DSOX1102G (thanks again e14!) arrives tomorrow so I am thinking of doing a quick comparison post on the three after arrival. The Siglent is a competent scope and is the one I have primarily used up until now. There are things about the Rigol I like better but I keep returning to the Siglent because I have had it longer and have familiarity through use, plus I very rarely have need for 4 channels. I am anxious to see what benefits the Keysight might have.

Hi Frank,

Even protocol decoding sometimes isn't necessary, it depends on how much control there is over the device under test sometimes.
I used to just visually+mentally decode I2C, without software assistance, and force the device under test to repeat stuff if needed, or to toggle a line deliberately, to trigger on that instead. I had a CRT-based analog scope with storage at the time (Hitachi), which was a nice interim technology before full DSO.
Similarly with SPI, sometimes there is enough information to not need to capture all lines, to do a mental decode.

Lacking your ability to decode serial with my mushware I have been using sigrok and an inexpensive Chinese logic analyzer :-).

Congratulations Andrew, You will have to give us a little demo when it arrives.

I did think about the 2-channel version but the extra 2 channels isn't that more expensive. I really quite fancied a Keysight but can't justify the cost really; I think that Siglent will keep me happy for some time. I shall look forward to the comparison though Frank.

The Siglents are great value and very capable...

Make sure you update the firmware on your DSOX1102GDSOX1102G when it arrives. When I got mine, it was loaded with an older firmware that lacked some of the FRA features.
