Specify DC offset of waveform


When using waveform function generation channels, Offset represents offsetting of a signal from zero, or the mean value of the waveform.


The waveform offset can be between –5 and 5. Ensure that Gain x Voltage + Offset falls within the valid rages of output voltage of the device.


Change the offset of the waveform function generation channel to 2 volts.

s = daq.createSession('digilent');
fgenCh = addFunctionGeneratorChannel(s, 'AD1', 1, 'Sine');
fgenCh.Offset = 2
fgenCh = 

Data acquisition sine waveform generator '1' on device 'AD1':
