The Digilent BNC Adapter Board is a simple add-on board intended to be used with the Digilent Analog Discovery 2, which allows you to use standard BNC-terminated test leads and probes with your pocket-sized oscilloscope. The adapter 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 Analog 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 Analog Discovery’s output impedance with standard 50-ohm test leads or to be directly tied to the lead. Additionally, the adapter board takes the oscilloscope bandwidth from 9 MHz (wire harness) to 30 MHz on the Digilent Analog Discovery 2.
Allows the use of standard BNC-terminated test leads and probes on your Analog 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 Analog Discovery become single-ended with the negative input connected to the ground
