Multi-Function: Read Analog Input and then Write Signal on Analog Output

[David_A]

Overview
This VI will read in an analog input channel and then write that signal out on an analog output channel on the same device.

Description:
The example would shows you  how to generate a signal from the Analog Output pin of the DAQ hardware and sequently acquire the generated signal and shows what the signal is. It is a great simple way to verify both of the functions of the hardware.

Steps to implement or execute code
To implement this example:

1. Define the physical channel to be used for Input and Output
2. (Optional) Set the rest of the parameters as needed
3. Run the VI

To execute this example:

1. Install the required software.
2. Connect the DAQ hardware that supports the Analog Input and Output features
3. Confirm the connection with the MAX with TestPanel
4. Open the VI and refer the Implement Steps

Requirements
Software
LabVIEW 2012 or compatible
NI-DAQmx 16.0 or compatible

Hardware
cDAQ with C series Analog Input Output Module

When I run this vi using an external function generator, the ao and ai signal magnitudes (p-p) differ by several hundred millivolts. The difference appears to vary with ai magnitude and maybe even frequency. Any idea what gives? I'm using cdaq ai and ao modules.
