Color Pattern Generator

TV color pattern generator creates color video signals for adjusting video signals of TV or monitor, classified by NTSC and PAL method.
A PAL method can be made differently depending on frequency by nations, which consists of sync signal, RF output, sound output, and video output.
It is hand held and conveniently portable. Power on/off, channel up/down, sound switch, band switch, and color pattern are on the front as a membrane type. Since both the internal charging battery and the external power can be used, power will be automatically turned off when the device is idle for a certain time. This protects against battery waste.
