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 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 may be spots on the image. If the coaxial cable is too
long, it will reduce the chroma level.
2.3.3 PTZ controller
Displays and allows for analysis of analog video and controls pan/tilt/zoom functions of an analog PTZ
camera. 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.
2.3.4 Enhanced Color bar generator
The newly added gray-scale image test, allows the tester to test the monitor for optimal gray-scale
performance. 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
2.3.5 DC12V 1A output power
The unit can power a camera with 12V DC (1A) power output from the tester. It is helpful for
determining powerline issues or if power supply box is malfunctioning.
2.3.6 Audio testing
Test the audio input from pickup devices. Connect the tester and pickup device with the audio cable.
Consult your local laws and regulations on recording audio and using audio devices. In the
United States of America and all individual states thereof, there are federal and state laws that
limit your ability to monitor and / or record audio. These laws expose you to the risk of criminal
prosecution and potentially give an injured party a civil claim for money damages against you.
2.3.7 Cable tester
Connect a LAN cable from the ST-HDoC/MM unit to the included blue remote cable tester. The unit
will test for connection status, cable type and the status of each wires conductivity will be displayed.
