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
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.
2.3.29 DC 12V 2A power output port and DC 5V 2A USB power port
The unit can power a camera with its DC 12V 2A power output. Also included is a built in DC 5V 2A
power output port used to charge USB devices. NOTE: This USB port is for charging only and has no
ability to transfer data.
Test the audio from mic level input devices. Connect the tester and mic level device with the audio
cable. Supports audio recording and output. to monitor and / or record audio.
Test LAN cable or telephone cable.
Connect LAN cable or telephone cable with the tester and cable tester. And then the connecting status,
cable type and the sequence of wires will be displayed, as well as display the serial number of the cable
tester kit.
