Color TV Signal Generator Audio Video Test Equipment - 1Vp-P/75Ω - Y, RY, BY

Color TV Signal Generator Audio Video Test Equipment - 1Vp-p/75Ω - Y, RY, BY


Product information:

AS305E color TV signal generator is a full-channel, multi-standard color TV signal generator. It uses an intermediate frequency vestigial sideband modulation and then frequency conversion radio frequency mode to ensure that the signal has consistent characteristics in the entire TV bandwidth, so it can be used as a standard-level TV signal source and a high-performance modulator. The channel, frequency, TV format, and output level of the signal source are all displayed on an LCD screen at the same time. Each video signal has independent key operation and instructions, so the operation and use are very convenient, and the display is intuitive. Audio Video Test Equipment

The signal generator Audio Video Test Equipment not only has video signal and radio frequency signal output (the output amplitude of video signal and radio frequency signal are both variable), but also has external video signal and audio signal input modulation function; color and brightness separation signal (S-VIDEO) can be added as needed , Video component signal (Y, RY, BY), synchronization, blanking pulse signal output. The signal generator is very suitable for scientific research institutions, schools, factories and other units.
