The VTDS 9563 pulse limiter is used to protect sensitive inputs of RF measuring instruments, e.g. measuring receivers or spectrum analysers.
The pulse limiter VTSD 9563 should protect the receiver input from excessive disturbance levels.
The pulse limiter can be used bidirectionally. The N plug and the N socket can therefore be connected to the signal source or to the display device to be protected.
If there are very high levels, they will be cut in the time domain. Cutting the signal in the time domain means – after a Fourier transformation – that additional spectral lines emerge in the frequency domain (intermodulation). In such a case the receiver input was successfully protected, however the measurement has to be rejected as invalid.
