generates four sub-carriers (image, sound, color and lateral
band), which are the main components of a TV signal, either
in IF, VHF or UHF bands. The level of every sub-carrier is
ajustable by step of 0.5 dB from the keyboard.
Associated to a spectrum analyser, it allows
to measure the main RF characteristics of a transposer in
UHF and VHF bands such as linearity, transmodulation, differential
gain, AGC efficiency, sensibility, signal/noise ratio.
The measurement sequences can be automated
through the build-in IEEE 488 (HPIB/GPIB) interface.
Thanks to its sturdiness and its easy setting-up,
it can be used as well for on-site application as for laboratory
us to get detailed specifications
