Rigol Power Supplies
« on: July 04, 2020, 11:13:05 pm »
I’m looking for a triple output bench power supply and was set on getting a Keysight model until I noticed that a Rigol PS with similar specs is 1/3 to 1/2 the price of the Keysight.

I’ve always believed in getting what you pay for... What will I be sacrificing by going with a Rigol? Performance? Reliability? Quality? Nothing?
Complexity is the number-one enemy of high-quality code.

I really like the low current measurement feature on the Keysight E36313A I have. But if I had to buy a PSU again I'd take a long look at the more recent GW Instek PSU: GPP-4323 (review: https://www.electrobob.com/gpp-4323-power-supply-review/ ). It ticks all the boxes: fully isolated outputs (which the Rigol DP832 doesn't have) and a numeric keypad (which the Siglent in the same price class doesn't have).
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Rigol/Siglent/GWI

Cant really go wrong with any of them, anything with a fat torrid in it is easily a winner.  Just look over each one and see what fits best for you

Siglent can be networked which is handy for scpi

Not to hijack the thread but I'm in the same boat, looking for my first supply, want to buy something decent, doesn't have to be the top of the line, I'm not inventing time travel over here but I know crappy supplies can kill things they are connected to when you turn the outputs on and stuff. I was looking at either the Siglent SPD1305X or the SPD3303C, I would really love to have more than 1 output you know, just in case I need it but I saw Dave's old teardown on eevblog and was wondering if there is something with better internal components around the same price? And have they fixed the issues with the knobs being too far apart and jiggly? Or which Rigol would be around the same range? I could up my budget if needed, I don't want to buy something with crappy parts about it haha.

Also do the Rigol's come with all of the features unlocked now? I know there is a website out there that will generate keys to unlock them, does that still work with the newest models if they don't come with everything unlocked?

It has a uncontrollable jolt upon powering on. That alone disqualifies it.

How about the GW Instek GPE-2323 ? It has the 1mA/1mV resolution the SPD1305X has and 2 channels like the SPD3303C has. And it is cheaper compared to both (at least in the shop I checked).

What is the price difference between both (identical) units? :)

I would suggest possibly the then both the Lecroy and Instek are the same as the Siglent case wise  ;)

What were they thinking?
Keeping the 'GND' point centred between CH1 and CH2, as they're the two channels that can be set to Series / Parallel operation.

Then, to make the connections mirrored, shift one channel to the left.

It seems fine, as the buttons are (thankfully) in the same physical orientation as the outputs.

Maybe better to shift the 'GND' to the far left or right, but I guess it's a convention to centre it like this.

They will surely issue a revised edition when the "woke left" discovers that they still have "Master" & "Slave" printed on the face plate...

... and it seems impossible to order via keysight's website unless I'm missing something. I only see options for the resellers, none of which seem to take the 25% off code... perhaps one has to *gasp* call them.
