patterns format and check picture content and sound quality accordingly:
Source Test signal (generator) Test pattern (format/image)
Analog /Digital Tuner RF cable Full Band (VHF/UHF) + CATV DVB-T
SCART1 (CVBS) Chroma/Fluke PAL Half Color & Gray bars

Audio tones can be defined by the factory (ie: 1KHz & 3KHz, sweep, …).
Picture video formats can be changed by the factory according to their own standard.
1.3. ADC Calibration
Two inputs require an ADC calibration for the time being, That are:
VGA
Provide a test signal 1024×768@60Hz with White Black squares.
Select the corresponding “Auto Color” submenu item from “Factory Menu”, then press ”OK” to
start.
When VGA channel is aligned, SCART-RGB is also aligned, so it is not necessary for RGB to be
separately aligned.
CMP
Provide a test signal 576i@50Hz with 100% 8 steps Color Bar.
Select the corresponding “Auto Color” submenu item from “Factory Menu”, then press ”OK” to
