Solution
If the error does not indicate any valid choices, this means that your NI data acquisition device does not support analog triggers.
For users of the NI 9233 and NI 9234 modules, triggering acquisition works differently. For guidance on how to set up triggering with these modules, please refer to the following article: Can I Trigger an NI 9233 or NI 9234 Module?
It is important to note that if your device is a simulated device, triggering is not supported on any version of DAQmx.
