R&S PSU number of channels needed

salomonander:
Hey,
I often need voltages like +-15v and +-18v. Will i need to get at least a two channel psu? Or can the r&s supplies do it with one channel?

Thanks
tautech:
Split rail designs normally need a 0V reference where a 2ch PSU in Series mode/configuration is the normal solution although a on-board voltage divider or LM78**/79** regulators are sometimes also used.

18V spit rail will require 36V or more with is a value beyond what is normally considered the 'industry safe' of ~30V.

Best versatility will be provided with a 2ch PSU providing 30V/channel.

Thanks!

Pretty much all R&S supplies can output at least 20 volts, and several go up to 32, 64, or 100 volts

We also sell a four-quadrant SMU (the NGU) that directly supports -20 volts to +20 volts.  If you want to do it all with one channel on one supply, that would be the easiest way to do it.

you have many who track rails IE   adjust them simultaneously ... 1 master the other channel as slave

unless you go with fixed ones too ... ?  it depends of your current requirements

0-30vdc (per channel) models are the most common, some have switches to do single/ separated, in serial or in parallel,  but  a positive and negative one at the same time,  haven't seen a lot

as Tautech wrote,  you need a ground reference and isolated supplies from each other ....  and you put them as attached image, nothing fancy,  but you need to adjust them separately ...
