content: 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?

content: 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).

content: Rigol/Siglent/GWICant 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 youSiglent can be networked which is handy for scpi

content: Quote from: hmjgriffon on July 12, 2020, 03:30:38 pmHow 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).
