For the BNC-2090A (rack mount), we are using the digital I/O signals as outputs. For the high state, can you set it to another voltage instead of 5V? Say 2.5 or 3.3V.
Or are the digital outputs confined to 0V and 5V only?
It would completely depend on the instrument capability you connect the rack mount accessory. In terms of Digital I/O signals, I believe the accessory just routes the signal from the input connector to the front panel terminals, unlike the analog lines which has place holders for resistors or capacitors.
