the digitally controlled r&s®vk4190 power amplifiers are available in a standard version or a special version with built-in receiver input protection. this option reliably protects the receiver input from destruction in the presence of hf interference on the antenna (caused by nearby transmitters) up to 100 v (rms) (corresponding to a power of 200 w into 50 ω).
the r&s®vk4190 with built-in receiver input protection should be selected whenever undisturbed reception of useful signals is required under extreme conditions.
