TV transmission systems such as TV transmitters, TV transposers and CATV systems are analogue or digital systems for the transmission of picture information. The signals are basically video amplitude and pulse modulated carriers, accompanied mostly by two frequency modulated sound carriers.

Transmission errors can occur because of imperfections in the total transmission path, such as bandwidth limitation, linear and non-linear distortions, as well as the actual vestigial sideband process itself. These errors can only be detected and measured by using suitable test signals.

A VF/RF test-signal generator provides all required signals for static, dynamic and step-function test measurement. By means of a separate demodulator the test signals can be analysed, evaluated and plotted.

All our products are measured, tested and estimated using this system.
