2.3.8 Analog camera test
Displays an analog camera image on the 3.5 inch 480*320 resolution LCD screen. Supports PAL &
NTSC formats. The LCD screen's back light brightness, video image brightness, contrast and color
saturation are all adjustable.
2.3.9 Video level meter（* Optional ）
Perform NTSC and PAL video amplitude signal measurements for PEAK to PEAK, SYNC levels and
COLOR BURST Chroma level.
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 lead to wash out of the image
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
