Theory of Operation

Theory of Operation

The theory of operation begins with a general description of the test set. This is followed by more detailed operating theory. The operation of each group is described briefly, to the assembly level only. Detailed component-level circuit theory is not provided.

System Theory

Refer to Figure 8-1 on page 8-2. The test set consists of three main components: a power supply, front panel display, and main switch board. The purpose of the power supply is to supply power to both the front panel display and the main switch board. The front panel display serves to indicate the switching paths to the user. Finally, the main switch board does the actual switching between the different ports.

A1 Power Supply Theory

The switching power supply provides regulated dc voltages to power all assemblies in the test set. A dc cable provides power to the main switch board. A connector from the main switch board to the front panel display provides dc power and control signals to the front panel. The power supply provides the following supplies: +24 V, +12 V, +5 V.

The power LED on the front panel indicates that the instrument is on and that the power supply is providing power.
