The video bandwidth represents the ability of the power sensor and meter to follow the 
power envelope of the input signal. The power envelope of the input signal is, in some 
cases, determined by the signal's modulation bandwidth, and hence video bandwidth is 
sometimes referred to as modulation bandwidth.
