Using the Digilent BNC Adapter Board is easy. First, connect it to your Digilent Analog Discovery 2. Then, you can attach standard BNC - terminated test leads and probes to start using your oscilloscope. To set the coupling for the oscilloscope channels, just adjust the jumper behind the BNC input connector. For the AWG channels, select the appropriate 50 - ohm or 0 - ohm termination according to your needs. When using it, make sure all connections are secure to avoid signal interference. Also, don't expose the board to extreme temperatures or moisture. For maintenance, keep it clean and free from dust. If you have any problems, refer to the reference manual or check the Digilent Resource Page.
