Lab bench power supply - Keysight or Rigol or GW Instek ??
(1/5) > >>
PavelKCZ:
Hello,

I am trying to select my (most probably) last power supply for my cave.
I already read tons of marketing materials, datasheets etc. I already saw really a lot of YT videos about various power supplies.
After all this, it seems that my selection is limited to one of those three types:

1. Keysight EDU36311A (nice, compact, but a bit limited when it comes to remote communication with PC).
2. Rigol DP832A (plenty of features, but incredibly long - 42 cm and also noisy)
3. GW Instek GPP-4323 (hidden gem, which is sold rebranded as a LeCroy for twice the price)

If you must choose one of those three, please write me :)
I really would like to know the pros/cons from peoples, who already have and use one or more of those three.

Thx PavelKCZ

Have you considered Rohde & Schwarz?  We have a very wide range of power supplies with different performance, feature sets, and price points.

I have used (and produced a short video on) every single power supply we make, so if you have any questions, please let me know!

Edit :  Některé z našich napájecích zdrojů jsou vyráběny v České republice :)

I have the GWW-instek, with LAN connection. It is indeed a gem; you get a good working PS with low DC ripple and constant load functionality. It was my best buy of 2023. But in the end, the intended use case at your side / budget is the determining factor.

Rigol DP832. I have 10 of them since almost 10 years and they all still work. SCPI per USB works as well. OK, they are loud. But my Keysight spectrum analyzer and VNA make alot more noise, so ...
