Hardware

  • PXI-6733

Issue Details

As the power-on state of PXI-6733 is stated as 0V (±200 mV), does it mean that the ±200 mV is the zero error, as it will have the possibility of the voltage to be output to 200 mV when power on the PXI first?
If yes, is there a way to ensure that power-on state to maintain at 0 V?

Solution

Yes, there is a possibility of the voltage to be output to 200 mV when power on the PXI first.
There is no way to ensure that power-on state to maintain at 0 V.
A common way to mitigate this is to use an external switch between PXI-6733 and the equipment and have the switch disconnect the circuit between PXI-6733 and the equipment during power on. 
After PXI-6733 is powered on and apply the 0V setting, then connect the switch.
