V. Connecting to PulseBlaster Devices
Connector Information
BNC Header Connectors
The four bracket-mounted BNC connectors outputs the first four bits of the output word (bit 0 to bit 3).
BNC 0 outputs bit 0, BNC 1 outputs bit 1, etc. The figure below shows the location of the BNC connectors on
the mounting-bracket.
If using a high input impedance oscilloscope with BNC connecters to monitor the PulseBlaster's output via
the BNC connectors, place a resistor that matches the characteristic impedance of the transmission cable in
parallel with the coaxial cable at the oscilloscope input (e.g., a 50 Ω resistor with a 50 Ω transmission cable,
see Figures 8 and 9 below). When using an oscilloscope with an adjustable bandwidth, set the bandwidth to
as large as possible. Failure to do so may yield inaccurate readouts on the oscilloscope.
