Test System Synchronization Overview
Test System Synchronization Overview
February 14, 2000
Description
Typical test systems include an external controller with a GPIB connection to the test set, an RF (and possible
AF) connection between the test set and a mobile station under test, and a serial connection between the
mobile station and the external controller.
Synchronizing an external controller with the test set and a mobile station under test ensures that no device
does something before it is supposed to, which can cause errors, or does something well after it could have,
which wastes time.

Sequential versus overlapped commands
The test set uses both sequential and overlapped commands. Sequential commands are easiest to synchronize
