LOGIC Switch: TTL
Connect a cable from the SYNC OUT/TRIG IN connector to the TRIG input of an
oscilloscope (preferably one rated for at least 2OMHz.) A second cable from the main
output should be connected to a male arm of a BNC T-connector. On a second arm of
the T-connector, a2W 50Q termination should be installed. The third arm is then connected
to the oscilloscope input. Alternatively, a BNC 50Q feedthru adapter may be placed
between the output cable and the oscilloscope input. Or, a 50Q resistor may be placed
across a BNC-banana plug adapter at the output, and a scope probe can the clipped onto
the resistor. Any of the three methods for terminating the ouput in 50Q can be used.
Set the oscilloscope to trigger externally. Then follow the instructions on the next page,
and compare what is seen on the oscilloscope to what is described. Only approximate
values are needed to confirm operation.
