Bug Fixes
- Multi-output power supplies now apply every command to the selected channel. On Keysight E363xx and Rigol DP800 series supplies, the channels of a single instrument share one USB session, and the shared driver stayed bound to whichever channel was opened first. Commands that don’t name a channel — setting voltage or current, enabling/disabling the output, and reading state — were applied to that first channel instead of the one you selected. On the Keysight E36312A this looked like a limits problem: a voltage setpoint above 6V on CH2 or CH3 (25V channels) was rejected, because the write was actually reaching CH1 (6V max). Each command now targets the correct channel.
