Digilent BNC Adapter Board

The Digilent BNC Adaptor Board is a simple add-on board intended to be used with the Digilent Analogue Discovery 2, which allows you to use standard BNC-terminated test leads and probes with your pocket-sized oscilloscope. The adaptor board provides BNC terminations to each of the two oscilloscope channels and enables you to AC couple or DC couple signals to the oscilloscope in the Analogue Discovery.

Each channel of the oscilloscope can be selected as AC or DC, coupled by adjusting the jumper that is located behind that channel’s BNC input connector. In addition, the two AWG channels are equipped with BNC terminations, and each channel can have either the 50-ohm or the 0-ohm termination selected. This enables the user to match the Analogue Discovery’s output impedance with standard 50-ohm test leads or to be directly tied to the lead.

• Allows the use of standard BNC-terminated test leads and probes on your Analogue Discovery
• Selectable AC and DC coupling to oscilloscope probes
• Selectable 50-ohm or 0-ohm output impedance on arbitrary waveform generator (AWG) channels
• With the Discovery BNC, the differential scope inputs of the Analogue Discovery become single-ended with the negative input connected to the ground
