Color-Bar Generator (Tv Out) - Security Tronix ST-IP-TEST User Manual

Video signal PEAK to PEAK level: For NTSC format, the video signal level is 140±15IRE
For PAL format, the video signal level is 1000±200mV
If the level is too low, it will cause the image to lose quality and limit the distance it will travel over cable. If
the level is too high, it will distort the image.
SYNC level: Tests 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
image.
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 become lighter. If the
Chroma level is too high, there will be distortions on the image. If the coaxial cable is too long, it will reduce the
chroma level.

3.3.2 Color-bar generator (TV OUT)

Click on the icon to open the Color-bar generator (TV OUT). The IP BUDDY+ meter sends the color bars via its
VIDEO OUT BNC port. Click on the "PAL" button to switch between PAL or NTSC output formats. Select the different color
bar choices at the bottom. To make the color bars full screen, double tap on the image. This is used to test for a problem in the
network of cable, connectors, and active processing equipment going from the camera back to the monitoring area.
