Back in the day that supply was made, symmetrical power supplies were common. e.g. +-12 and +-15 for Op amp circuits and 5V was a common logic supply.
Today you still see 5V, but you also see .8, 1.8, 3.3. and 5V
We also see a fair amount of OP amps that operate on 5V.
Supplies like the Tek have a "tracking mode" where one knob adjusts th epositive and negative voltages. "tracking" means more than that. but for now, that's what it means. The Tek is three power supplies, not one.
So, the question is: What do you intend to use the supply for?
