Hi mini, I have decided to go with the DHO series and I am just figuring out which power supply I will need, although there are good power supplies from keysight, but gosh the isolated one cost $2400 CAD, from Tequipments( A distributor) I could get the E3620A for $1100 but it is way outdated, it does not have any features rather than providing basic power supply https://www.keysight.com/ca/en/product/E3620A/50w-dual-output-power-supply-two-25v-1a.html now this comes with a price of around $1500 CAD, Keysight is going to discontinue this version and the new version that they have replaced this with is E36300 series, the E36311A is having +25 volt and -25 volt on both output but they share the same common ground, lol. https://www.keysight.com/ca/en/product/E36311A/80w-triple-output-power-supply-6v-5a-25v-1a.html It comes with a price of $2000 CAD I can't believe that decent power supply having separate electrically isolated supply doesn't come within a cost of $2k, the one they have the isolated outputs is E36312A which have so many features that I guess I do not need https://www.keysight.com/ca/en/product/E36312A/80w-triple-output-power-supply-6v-5a-2x-25v-1a.html Power Output: 80WDC output:One: 0 to 6V, 0 to 5ATwo: 0 to 25V, 0 to 1AThree: 0 to 25V, 0 to 1A4.3-inch color LCD displayColor-coded channelsIndividual knobs for voltage and currentUSB/LANDigital I/O portIndividual on/off on all channelsElectrically isolated channelsFront and rear output terminalsData LoggingOutput SequencingOutput LISTAuto series/parallel connections2-wire or 4-wire remote senseOver Voltage, Over Current and Over Temp ProtectionIncludes BV0003B Power Supply app there are some features that are really useful like remote sensing, individual on/off on all channels, USB option, preset of voltage and current option, but most of them I dont think I need.Image Now, there is Keithley 2231A-30-3 which comes with a decent price range of around $1300 which seems pretty good
