Set up threshold trigger on analog input for DT9837A or B

[daquser]

According to the user's manual of DT9837 series,  user can set up threshold trigger on analog input channel 0,  and can also program the threshold trigger value from 0.2 V to 9.8 V.  Is there sample code snippet on how to set up and modify the threshold trigger value in Matlab?

Hello @daquser.

Threshold triggering is not supported in Data Translation's DAQ Adaptor for MATLAB.  However, you could create your own custom code to analyze acquired data and only begin processing the data once a specific voltage level was reached.

When using Data Translation devices with MATLAB, the supported trigger option is an external TTL trigger, with trigger conditions for either rising edge or falling edge.
