Description
Vega, RF Channel Simulator from TeamCast, is the right tool to test and qualify your and fix receivers for any kind of Digital TV standards. Thanks to
its powerful real time process, from your basic original signal, Vega can produce a realistic broadcast transmission to check the good behaviour and the
limits of your receiver on the field. With Vega, a wide panel of laboratories, chipsets and receivers manufacturers have the tool to secure time-to-market,
performance, quality assurance for their products and services. Dedicated to Tests & Measu?rement, Vega exists in two form factors (Rack form and Lab form)
for a better installation inside your facility (R&D, Production Lines,…).
High performance & Reliability
The VEGA RF Channel Simulator supports VHF band, UHF Band and S-Band signals (others frequencies band on request). Covering 1.5 MHz up to 10 MHz Channel
bandwidth signals, VEGA handles the terrestrial, salite and hybrid channels propagation modes. It’s compact and easy to use.
