Rigol's own figures, as its documents state them; each links to the page it is on.
Supplies steady, adjustable DC voltages to power a circuit, with a current limit to protect it, and shows how much current it draws.
Powers the boards and instruments under test from a script: sets the voltage and current limit, switches each output and records the draw, so a whole test, power included, runs end to end without anyone at the bench.
It powers the boards and instruments under test from a script, with a current limit, and its own voltage and current readback is a reference for the scopes' power readings: with the current probe on its output lead, a channel in amps times a channel in volts should agree with the supply's own volts times amps.
The tests we will run with it when it arrives; the results will appear here.
Back to the bench: everything NovaOS is developed and measured with.
