YDC-868-6 NTSC/PAL Multi-standard TV signal generator - 868-6

YDC-868-Series TV Signal Generator

YDC-868-6 NTSC/PAL Multi-standard TV signal generator

868-6 multi-standard television signal generator, which is particularly suited to TV manufacturers and maintenance departments for detection purposes. With video, S-Video, sound, audio and RF output ports, which can be suit to different users. The machine consists of microcontroller and color coding, control circuit and other components, software produced by the two formats PAL and NTSC system, the ten test signals, the image clear and stable, independent of temperature, humidity, voltage.

12,1Vp-p video output: check the video channel.

Usage
Open the unit, connected to the closed-circuit antenna, the L segment with TV, press the switch L-band instrument; TV with Section H, the band switches the instrument H Press; TV in the U section, this instrument U-band switch button is pressed. Aligned band, the fine-tuning to adjust the frequency corresponding to the received channel, received signal to select the image on the panel.
Standard options: Key lift when PAL, audio 6.5MHz
Button is pressed for NTSC, audio 4.5MHz
Display: button raise when manually select image
Button is pressed to automatically select the image
