Hello guys.
In order to perform voltage measurements with the PXI4464, I am writing a code in C using the LabWindows.
In a simple way, I have created the Task, the Voltage Channel and set the Timing. To do this, I used the following functions:
DAQmxCreateTask("",&taskHandle);
DAQmxCreateAIVoltageChan(taskHandle ,chan ,"", DAQmx_Val_Cfg_Default, min, max, DAQmx_Val_Volts, NULL);
DAQmxCfgSampClkTiming(taskHandle, clockSource, rate, DAQmx_Val_Rising, DAQmx_Val_ContSamps, 1000);
Sometimes I need to perform test using DC coupling mode; sometimes using AC coupling mode. However, I did not find how to set the coupling mode using the DAQmx functions.
Could anyone help me?
Regards,
Johann
