7.Operation

The PLS-345 offers three different methods for switching A/B paths:

1.Manual A/B Switching: The manual A/B Switches on the PLS front panel are used to initiate switching of one or more A/B Circuits.

2.Code Activated A/B Switching: ASCII commands are sent to the PLS to initiate switching of one or more A/B Circuits.

3.Automated A/B Switching (Monitor Mode): The PLS monitors a signal received via the Monitor Input Port, and switches one or more A/B Circuits according to user-defined parameters.

These methods are discussed in the sections that follow.

7.1. Manual A/B Switching

The most basic method for switching A/B paths is accomplished using the manual A/B switches on the PLS front panel. When performing Manual A/B switching, note the following:

￿The Master A/B Switch (Labeled "All") can be used to switch all three A/B Circuits.

￿When an A/B Circuit is switched, the corresponding LED indicators on the instrument front panel and back panel will light.
