Siglent SPD3303D review
<< < (29/35) > >>
Helix70:
In Dave's review a while back, he noticed some loose 4mm sockets. This was rightly critisiced by him, and in here.

On our power supplies (recently purchased SPD3303X and SPD3303X-E *2) all of the 4mm plugs that I tried fit normally. That includes the shrouded to non shrouded adapters, our stackable 4mm leads from Jaycar, and a some other random ones. None of them feel loose. Perhaps they fixed this?

They are still non standard spacing, but this isn't all that important to me to be honest.

With the new firmware, the display makes much more sense, and can set the set points independently of the measured output. It is also worth noting that the 2.5/3.3/5V channel is overload protected, but the current limit is not adjustable. A pity, but you do have 2 other channels with full control.

This PC software is functional, but not great (being kind here - come on Siglent, it needs more than a day's work).

Overall, happy.

Thanks. You haven't tried to convince me on sending more cash Trio's way.... but you have watered the seeds already planted.  Its unlikely that D and C models will get any love since they're "old", that may also include being manufactured with older stock posts etc and so the issue may be evident....  but if I am going to hand out $720 then that brings back into play some of the GW-Instek models into the decision, and maybe even the Rigol.... sigh, more research needed.  Or just buy the C and be done with it :)

I too am looking at the Siglent SPD3303 models, but would only consider sending cash Trio's way if they were a bit more realistic on price. In the US the SPD3303X-E is about 15% cheaper than the Rigol DP832, but from Trio the SPD3303X-E is actually priced higher than the DP832 from Emona. AU$720 doesn't compare favourably against US$389 for the SPD3303X-E, even taking the low exchange rate and GST into account...

I have to agree, the DP832 went to the forefront of my list once I started to convince myself that spending that amount of cash made sense.... although I've bought a few parts on ebay to get me out of the immediate need I had (plus I'm a cheapa$$, and it'll probably be100% better than the collection of dodgy transformers I have today)

If you are serious, give Trio a call. You never know...
