Something is happen in some of recent builds that settling time for output enable/disable when channels are in tracking mode is slowed down for many hundred of times. Initially that time was about 120us:
... and now is about 100 ms (rising, output enable):
... or 60 ms (falling, output disable):
The same results I got with SCPI commands OUTP. Also on start-up I got 100 ms, therefore enabling both channels output has to be done sequentially as the latest task when everything else is already set up (voltage, current, etc.)
100 ms delay also exists when channels are coupled. Although that is not so critical as in case of tracking, it possibly has the same root.
