Issues Measuring Demux with PXI M3300A Module - Zero Voltage Output

[AbrarAraf]

Hi everyone,

I am working with the PXI M3300A module to measure a demux circuit. I applied signals using the AWG and connected the outputs to the DAQs as intended, but I keep getting output voltages of almost 0V.

To troubleshoot, I also set up a simple voltage divider circuit with identical resistors, expecting to see half of the input voltage at the output. However, the output still reads 0V.

I have checked the connections and confirmed the input signal. Has anyone experienced similar issues when measuring low-level signals? Any insights or troubleshooting steps would be greatly appreciated.

Without the code and connection diagram, one could assume that you're doing something wrong but cannot provide any guidance on where.
