Test system configurations
There are two test system configurations that can be used for Delta, Pulse Delta, and
Differential Conductance measurements and are shown in
panel stand-alone operation and the other is for remote programming (PC control system).
Both systems use serial communications (via RS-232 interface) between the Model 622x
and the Model 2182/2182A. The Model 622x sends setup commands to the
Model 2182/2182A, and the Model 2182/2182A sends Delta, Pulse Delta, or Differential
Conductance readings to the buffer of the Model 622x. Once the test is started, trigger
synchronization between the two instruments is controlled by the Trigger Link.
