Integrated uCurrent in new Rigol DP2031 lab power supply?!
(1/6) > >>

Just saw this pop up today: https://www.rigol.eu/products/dc-power/dp2000.html

Rigol has added a low-range current readback mode where the resolution is improved by factor 100x. Programming is still in mA level.

The programming and readback accuracies are slightly improved compared to the DP800 series. Readback is 0.15%+5mA (was 0.2%+5mA) and now also has a low-current range (up to 10mA) with 0.25%+28uA spec. The EEVblog's uCurrent does +/-0.1%+50uA in 1mV/mA range or +/-0.05%+50nA in 1mV/uA range, with a max +/-2.25A or +/-2.25mA measurement range, respectively..

I suppose it's not a bad addition, but it doesn't look like it's going to beat the uCurrent in pure accuracy.  28uA offset is still quite high if you're targeting <100uA applications. It could be OK if the offset remains reasonably consistent across output voltage changes (high CMRR), and/or it's possible to zero the instrument's offset as you may typically do before starting a low current measurement..

Other improvements are a (much) shorter processing time and dwell time.

There are also seems to be a new DP900 series, but that doesn't come with an uA current range and output/sense terminals on the back.

Looks like they copied this feature from the Keysight E36xxx series. Burden voltage, the distinguishing feature of the uCurrent, is not an issue for current sensing inside a power supply, because the sense lines will have been connected past the current shunt.
mikeselectricstuff:
Auto-ranging low-current readout is a feaure I find really useful on my Keithley 2280S.
On a bench supply doing development it's a really useful feature - it doesn't really need to be that accurate most of the time, as long as offset isn't too bad.
switchabl:
I wonder if they actually have the bandwidth to back up the 7.5ks/s sampling. It doesn't look like they have decreased the output capacitance (programming speed similar to DP832). If I remember correctly the fast-sampling Agilent PSUs used to have a separate high-frequency measurement path (current transformer?) to get around that.

If they are actually serious about it, the analysis functions may need some work as well. It looks like there is no way to trigger measurements (just real-time/trend display) and statistics are very limited. But maybe they will improve on that with future firmware updates.
uski:
It is really unfortunate that they kept the same crappy user interface, with the circular numbers and everything... just give me a normal keypad already
