Digilent Function Waveform Generator Channels

Waveform function generator channels on a Digilent® device can generate both standard and arbitrary function waveforms. For more information, see Waveform Types. This diagram shows the pin configuration on a typical Digilent Analog Discovery™ device. The yellow and the yellow/white lines represent the waveform generator channels, marked as W1 and W2 on the device.

Digilent Analog Discovery device pinout

To test the Analog Discovery device, create the following connection to acquire the generated waveform, and use it with the corresponding code:

  • 1+ (scope channel 1 positive) to WI through a 1K resistor.

  • 1– (scope channel 1 negative) W2 to GND.

This diagram depicts these connections on a breadboard.

Circuit wiring for Digilent Analog Discovery example

Unlike analog input channels, the waveform generator channels control their own frequency. If your DataAcquisition contains both waveform generator channels and any other type of acquisition channels, the waveform generator channels will have their own frequency and all other channels will inherit the DataAcquisition scan rate. If you have analog input channels in the DataAcquisition with waveform generator channels, the analog input channels start first and act as a trigger for the waveform generator channels.
