Amplifier Use Case: GPS-Synchronized 3-Phase
System for End-To-End Testing
This example shows how the three current outputs of a CMC 256-3 test set are
led to the synchronization inputs IAC of three CPC 100 test sets to drive their
high-current outputs. This way, the CPC 100 high-current outputs represent the
"amplified" CMC 256-3 outputs and, in this example, are connected to three
CTs.
