5. cies of 0 06 and 0 2 respectively The load voltage and load cur rent readback results provide the same levels of accuracy so you can be confident you are sourcing accurate low noise voltages and currents to your device under test DUT Three Fully Independent Outputs Each output of the Model 2231A 30 3 is fully programmable and can be turned on and off inde pendently from the other channels it essentially provides three power supplies in one instrument You can power up both the analog circuitry and the digital circuitry of a printed circuit board or a complete device all with the same instrument All Outputs Are Isolated from Each Other and from Ground Each output can power a circuit on a different ground reference The low connection on each output is not connected to any of the other outputs That means one supply can test three separate circuits on three different ground references or can power circuits that are transformer or optically isolated from each other Furthermore all outputs are not referenced to ground so the Model 2231A 30 3 can power both floating circuits and grounded circuits Power Bipolar Circuits Because the Model 2231A 30 3 s outputs are isolated one output can be turned effectively into a negative source by connecting its high terminal to the common reference point of a bipolar circuit A second output can connect its low terminal to the same com mon reference point The result is a positive output an
