Chapter 3: Operation

Adjust LCD brightness: Use keys number 7 (BR+) and 9 (BR-) to adjust the LCD screen’s brightness.

B. Measure signal strength (Vpp) and attenuation:

Video signal strength (attenuation): With the tester displaying the video signal (see A), press the “1” (IRE) key. The following is displayed:

MAX Vpp: The peak-to-peak amplitude of the video signal. The larger the video signal, the brighter the picture. 1 Vpp is minimum.

AVERAGE Vpp: The average peak-to-peak amplitude of the video signal.

SYNC SIGNAL: A camera’s sync pulses synchronize the camera with the monitor.

NO VIDEO: No signal, “No Video” will be displayed.

Example of attenuation: If the Vpp at the camera is 1.25 Vpp, and the Vpp at the end of the cable is 1.15 V, the attenuation is 8%.

C. Testing and controlling the camera motion (PTZ):

Connection. Connect the camera to the tester as shown in Figure 3-2, diagram A. The camera’s PTZ wires plug into the T+ and T- ports on the tester’s RS-422/485 jack (use the terminal block/alligator adapter).
