I have the E3640A DC power supply and I am attempting to do a voltage sweep from negative to positive however the instrument is not allowing me to do that.  Is the instrument capable of a negative voltage output?  Or do we need to purchase a different instrument?  I am trying to write the command to the instrument with the command VOLT -2
