I have three Agilent 6813B single phase power supplies, I want to form three phase out of them.
I know that it is possible to use the signal TRIG IN (back panel), but it is only for an event (step voltage, surge). The synchronization may be by delay or by phase. There is a button to change the phase output is the blue button or SHIFT + PHASE: enter the value in degrees. However this phase change will be compared to the internal reference which unfortunately is not synchronizable by the external. So we could have three 6813B to do the tri-phase, but after a few seconds, there would be lag between outputs, I do not advise to do this experiment with a LOAD. I tested setting of phase with my 6811B and compare to power line 60Hz.
