Thanks again for your good suggestions!

Hi Steve
 
    The guy's suggestions are  good. I very like this kind of feedback. I will remember his name,Leonerd
 
    The suggestion of improve the control way of setting knob, we had implemented the similar way as he suggesed in new SPD3000X power supply.
    About suggestion of display the set value and actual output value in the screen at same time, we think it is a good idea. I had discussed with Owen and our enigneer , and we will implement it in the next SPD3000X firmware.
 
    Very thank you for monitoring the EEVblog and forward this kind of feedback and some review video and  big issues to us. It is a very good commnication way with customer, and can help we improve our products.

Hi there,

Thanks for taking the time to look into this. I have one question though - would this feature only be added on the X version of the PSU, or will it be available on the D as well?

Siglent America:
Leonerd,

The C/D/S models use different FW than the new X/X-E models.
Your suggestions will only be implemented in the new X/X-E models for now. If there is enough demand for the change on the C/D/S versions then we will certainly look at doing it on those as well.

Because the new X-Series power supplies are only a few dollars more than the C/D/S models then then the D/S models will probably fade away. The LED version (C) is less expensive so I anticipate it will be around for a while. Of course, it doesn't hacve the larger LCD display so it cannot display as much information at once as the other models.

Thanks again for your suggestion!
Steve

It's understandable that the different series use different FW - I understand the X version has ethernet, so probably a different MCU inside, could be all sorts of other internals changed. But given the UI looks so similar in both cases, the idea itself should work fine either way.

You say "a few dollars more" - I see on siglent.eu the D version for €299 vs the X-E at €370 - that's not "a few dollars", that's nearly a third more. For the 1mV version, the S costs €399 vs the X at a massive €509. That's quite the difference there.

If you're saying you won't be further maintaining the D and S versions, then you may lose out on a portion of the market like hobbyists such as myself, who don't care about ethernet connection. If you are intending to discontinue the D/S versions, then I'm a little disappointed at having only just bought myself a new one.

Siglent America:
I don't have the international pricing handy, but only that for North America.

SPD3303C: $289
SPD3303D: $369
SPD3303S: $529

New SPD3303X: $539 ($10 more than the SPD3303S)
SPD3303X-E: $389 ($20 more than the SPD3303D).

And you are correct on why we changed the MPU, Leonerd.

With so many new products having just come out and more new ones coming soon then the Engineering manpower has to be considered, where to spend the Engineering resources. If enough customers with the D/S versions want the upgrade then we will certainly look at doing so.

if you would like to send me a PM with where an when you purchased your unit then I will pass that on to our appropriate people.
Steve
