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
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
A VF/RF test-signal
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.
