SYNC level: Testing the amplitude of the video sync pulse to verify if the video level is correct.
For NTSC format, the SYNC level is 40 ± 5IRE
For PAL format, the SYNC level is 300 ± 35mV
If the level is too low, it will cause the image to not frame out properly. If the level is too high, it will lead
to a poor quality
COLOR BURST level: Testing the color burst level will determine if the burst signal is sufficient to
trigger the displays color producing circuit. Burst will diminish in amplitude over longer cable runs and
can get fall below the threshold for the video display to show a color image.
For NTSC format, the Chroma standard level is 40 IRE
For PAL format, the Chroma standard level is 280mV
If the Chroma level is too low, the color will not be as deep, and some details of the image will get washed
out. If the Chroma level is too high, there will be spots on the image. If the coaxial cable is too long, it
will reduce the chroma level
2.3.11 PTZ controller
Displays and allows for analysis of analog video and controls Pan/tilt/zoom function of PTZ analog
cameras. For PTZ testing, setup the controlling parameters from the meter to match those of the camera:
e.g. PTZ protocol (PELCO-D, etc.), communication port (RS-485, etc.), baud rate, PTZ camera ID and
pan/tilt speed.
2.3.12 Enhanced Color bar generator
The tester sends out color bars via its BNC output to the monitor. This is used to test for a problem in
the cable going from the camera back to the monitoring area
2.3.13 DC
1
2V 2A power output port and 5VDC 2A USB power port
The unit can power a camera with its 12V DC 2A power output. Also included is a built in 5V DC 2A
