How long have you owned the SDS2504X+? I would say I am gentle, but I guess some equate to how fast I was turning the knob to using an electric drill.
I'm not apposed to buying another low cost product from Siglent to try it out. My only concern is if it does have similar problems, their higher end products may behave completely different. I had asked if their higher end Arbs would have the same problem. I don't think I ever got an answer.
I've had the SDS2504X+ over 3 years, as it's out of warranty now. I've never had any problems with it.
Things that annoy me:
1. I don't like confirmation dialogs, the confirmations should be optional (in settings) but for both Auto set and Default, you have to either multi-hit the button, or click the confirmation. Not terrible, but annoying to me.
2. Until the last firmware update (which needs to be rereleased) there was a persistent confirmation after screenshots that needed to be clicked away (it's corrected / option in fw 1.6.2+).
3. I want to be able to change the trace color for XY mode, but it's currently stuck on an annoying blue, that at the very least, should be a brighter hue.
4. A common problem with Siglent Bode plot (nit picking) the Bode plot system is completely separate from the main system, so it's a little weird going back and forth and there's some options I wish that were persistent. Not a big deal, the Bode plots are great, but some minor improvements would be nice.
I've owned the SDG2122X for longer than that, and I never had issues with that either. The rotary on the SDG does not feel as nice as the rotaries on the scope, but it has never failed me either. Full disclosure though, I use that specific SDG rotary less than I use the numeric keypad and other buttons.
My guess would be that your issue is more likely QC than anything else. Thousands of parts go out, some of them suck. But like I said, it doesn't feel as nice as the scope rotaries.
I agree with you, getting a lower end scope probably doesn't give you a good comparison of the hardware; I don't know if they use the same encoders or not, but I assume not until somebody says otherwise.
I think you should contact Siglent for a loaner so you can properly put it through its paces. Or ask if you can purchase it with an extended return period (60 or 90 days?) so you can properly test it, review it, and decide if you want to keep it.
Getting the 800 series stuff would probably still be fun, but I don't think it's remotely close to a taste of the 7000 series. I have absolutely no need for another scope, but I still had to stop myself from ordering the 800 a couple times. Stupid TEAS. 🙄
Thanks,
