Overview
The Discovery BNC adapter board is intended
to be used with the Analog Discovery™ tool to
enable the use of standard BNC terminated
test leads and probes. The adapter board
enables the user to AC couple or DC couple
signals to the oscilloscope in the Analog
Discovery.
Features include:
• Standard BNC interface to BNC
terminated test leads and oscilloscope
probes.
• Selectable AC and DC coupling to
oscilloscope probes.
• Selectable 50-ohm or 0-ohm output
impedance on Arbitrary Waveform
Generator (AWG) channels.
Functional Description
The Discovery BNC adapter board has BNC
terminations to each of the two oscilloscope
channels on 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.
The two AWG channels are equipped with
BNC terminations for use with BNC style test
leads. Each of the two channels 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
either standard 50-ohm test leads or to be
directly tied to the lead.
All the remaining signals from the Analog
Discovery pass through the adaptor to a
female header located on the outer edge of the
board.
