Hi, I have a qestion regarding this Rigol DP-932E power supply. Can I connect up the two 0-30V output to have +30V-0-(-30V) and whether the output voltage of one rail (say -30V) can synchronize with the other rail (+30V)? Also, in this configuration, can I adjust the current of each rail independently?
Thanks

Hi Wing, Welcome to the forum!
You absolutely can! The two isolated 0–30 V channels on the Rigol DP-932E can be placed in series (called external mode), with their junction used as 0 V. That gives up to approximately +30 V / 0 V / −30 V.
In the built-in series mode (internal), CH1 and CH2 voltage settings track together, so adjusting one should adjust both rails by the same magnitude.
It is also worth remembering that the centre point is only your circuit’s 0 V reference, and looking through the docs for this DC supply, requires using the external mode.
