Siglent SPD3303D review

<< < (8/35) > >>

FrankBuss:
There is a "Customer Service" navigation on their webpage http://www.siglent.com/en , but looks like they screwed it up, at least in Firefox and Opera it is not click-able. Last time I just wrote to sales@siglent.com (the only eMail address I could find on their webpage) with the request to forward it to technical support.

psycho0815:
it's clickable on chrome, but there's only links for msn-messenger and skype in the menu, no email. There is however an emailform on siglent.eu when you click on "contact us" right at the bottom of the page.

Personally i'd propably take the rigol over this one, but that's more of a gut thing than anything else.
Also, never heard anything bad about batronix (including own experiences), which is kind of a big point for me.

Zbig:
My gut feeling was more towards Siglent and I'm very glad I made that decision. Have you seen the massive thread dedicated to problems with Rigol? Well, my Siglent had only some issues with CH3 which are now fixed. Comparing to the Rigol, Siglent has:


* Each of the three channels properly isolated from each other
* No power-on/off spikes of any kind on the main CH1 and CH2 from the get go
* Parallel and serial modes do actually make the connections internally with relays hence no need for a shorting bar (yes, it matters to me)

Anyway, are you sure that's really the gut feeling? Or is it because Siglent's PSU didn't get Dave's attention? ;)

EDIT:
Oh, after reading some updates on the Rigol thread and how they "solved" the overheat issue: the fan on my Siglent is idling under no load conditions, I can barely hear it.

psycho0815:
Nah, believe it or not, but dave's not a factor here.
The overheating issue with the rigol seems to be fixed. I don't think anyone has actually tested yet, whether or not the overshoot issue is still an present in the newest rev.
As for the siglent fix. I don't want to solder in some bodge myself. I want the manufacturer to fix it. So if i can find a retailer, who can guarantee to deliver the newest rev. without the issues than maybe.
Also:
I really don't like the fact that i can't set a current limit on the 5V channel. I know i can use ch1 or 2 at 5V but still. Just doesn't seem thought through.
Also i want a number pad. I like knobs as well as the next guy, but i like being able to just punch in a value, too. It's digital anyway so there's really no excuse. Especially for stuff like the timer it would be alot more convenient. Sure the keypadlayout on the rigol is ridiculous, but at least it has one.

All that said, a 3 channel psu is more of a want than a need for me anyway so maybe i just wait a couple months and revisit the market than to see if the newest revs. ironed out all the kinks on either unit. 

Zbig:
Fair enough, the "auxiliary" nature of the CH3 and lack of the numerical keypad, while not being the issues for me personally, are perfectly valid points.
