Waveform output gain


When using waveform function generation channels, Gain represents the value by which the scaled waveform data is multiplied to get the output data.


The waveform gain 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 gain of the waveform function generation channel to 2 volts.

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

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