We have a test system with PXI-6541 digital waveform card that has never been used. I'm helping the test person debug the Labview program.
It appears the channels being used as inputs always have the 50 ohm driver active. In the product specification in the Generation Channel table, I see reference to "Data channel driver enable/disable control - Per Channel - Software Selectable". So does that mean if we need a DIO to be input only with high impedance the driver needs to be disabled? I am new to Labview so am not entirely clear on how the person is setting up the DIO as inputs and outputs but he described it as simply assigning a channel as IN will turn off the associated driver.
