Siglent SPD3303D review

<< < (28/35) > >>

Helix70:
Charles from the Siglent dealer here in Australia, Trio Test and Cal dropped in yesterday and picked the suspect unit up.

The problem was intermittent (of course), and seemed to be mainly to do with the LEDs behind the buttons. They would just not operate when the buttons were pushed, or they would stay on when the buttons were pushed. Other functions all worked as expected, despite the indications of the LEDs. There was also one instance of freezing when left on after entering screen save, so perhaps a faulty connector or solder joint.

My new unit should arrive shortly. Thanks for the great response!

We are about ready to release the new FW that shows both the programmed settings as well as the actual output values.

We'd like your opinion on which screen User Interface you prefer. Please see the three attached screen shots and let us know which one you prefer (UI-1, UI-2, UI-3) and we will use that one in our new FW.
Thanks
Steve

Glad to see Siglent is listening, well done. There are probably more customers to be had than just the ones that post on the forum  ;)

I like UI-2 but, why not make them all available and let the customers decide? Asking for a friend.

Thank you. 

Happy to oblige ;)

I am in two minds about posting in this thread or creating my own - well I guess this won out

Have been thinking I need a bench power supply better than my dodgy $10 ebay thing that runs off a wall plug and even with the quirks the Siglent seems to come out on top of the lower priced bunch.  Well except perhaps for the banana plug thing; that's pretty unforgiveable really. 

Anyway, the SPD3303C and D caught my eye because they're in a "comfortable" price point. Justifying more than the AU$440-$500 that they would turn out to be is harder to do to the financial controller - after all I am only a hobbyist, so it's probably hard to convince myself to go higher too!  So that's why I came to you all, to convince me why I should go up the scale.  :)

Here's Trio's (inc GST) pricing at the moment.....
C $439
D $481
S $655
X-E $720
X $974

I won't need 1mV or 1mA resolution, 10mV/10mA is fine.  The graphical display of the D and X-E are nice, but for me not essential, so I totally can get away with the C.  Since the price delta of the C and D is so minimal, and the benefit also so trivial, I can't see any compelling reason to go for the D version, EXCEPT if the UI changes noted earlier are also coming for the D because if the D is also getting the UI tweaks, then I'd opt for it.  Given the X and X-E firmware was out a few weeks ago, and the D and S models haven't seen an update since early 2015, I guess I know the answer (but I'm hoping the Siglent team watching these threads step in and say different).

So, anyone point out logic flaws in the above?  I can't really see the value in stepping from a sub-$500 unit to a $720 unit just to get both the setpoint and actual readings (as much as I would want that)....

One final thing, has anyone seen a vid of the C unit in action adjusting values?  I'd be interested in seeing how quickly it goes from setpoint to reading as that might make it seem laggy when using it. Or if anyone has one and wants to video it, youtube awaits :)
