The Discovery BNC Adapter Board is intended to be used with the Analog Discovery Tool to allow the use of standard BNC terminated test leads and probes. There are BNC connectors on the Analog Discovery for each of the two oscilloscope channels. Each channel of the oscilloscope can be paired as AC or DC by adjusting the jumper located behind the channel BNC input port. In addition, the two AWG channels are also equipped with BNC connectors, and each channel can have selected either the 50 Ohm or 0 Ohm termination. This allows the user to compare the output impedance of the Analog Discovery to either standard 50 ohm test leads or connect directly to the line.
