Setting Pointers and Changing Timing This section describes how to generate pointer movements within the transmitted SDH signal. When stress testing a network, you may want to move pointers or introduce a frequency offset. The CTS850 SDH/PDH Test Set allows you to control this type of testing five ways. You can: H Make discrete pointer movements under manual control H Make repetitive pointer movements at a rate you determine H Generate sequences of pointer movements H Introduce a frequency offset in the internally generated AU H Introduce a frequency offset in the transmit rate Setting Pointers To set up the CTS850 to make discrete or repetitive pointer movements: 1. Specify the pointer mode as follows: Press Menu Select Menu Highlight Button Page Parameter Select Choice TRANSMIT POINTERS & Pointer / Timing Pointer TIMING Mode Movement The choices allow you to choose to move pointers using time parameters or with a frequency offset. Selecting Pointer Movements moves pointers utilizing time parameters. CTS850 SDH/PDH Test Set User Manual 3 195 Setting Pointers and Changing Timing 2. Specify the pointer type as follows: Press Menu Select Menu Highlight Button Page Parameter Select Choice TRANSMIT POINTERS & Pointer Type AU Pointer TIMING TU Pointer Manual Pointer Control You can move pointers under manual control using the POINTER ACTION button on the front panel. To set up for this type of control, use the knob to highlight the Pointer Control line. There are three types of manual pointer movements: Single, Burst, and Continuous (see Figure 3 75). The choices are described in detail below; some require additional setup. Figure 3 75:Manual Pointer Control Choices 3 196 CTS850 SDH/PDH Test Set User Manual Setting Pointers and Changing Timing Single Pointer Movements. With Single selected, each press of the POINTER ACTION button on the front panel of the test set moves the pointer up or down by one location. The first press increments the pointer, the second press decrements it, the third press increments it, and so forth. Burst Pointer Movements. With Burst selected, pressing the front-panel POINTER ACTION button starts a burst of pointer movements. Each burst consists of a series of one-location pointer moveme
