Tuning range

The frequency range over which a receiver or other piece of equipment can be adjusted by means of a tuning control.

This definition does not completely cover the PMSE problem scenario. Therefore an improved definition was required:

Tuning range is the frequency range over which a receiver, transmitter or other piece of equipment (such as antennas) can be adjusted by means of a tuning control in consideration of required system performance.

Limiting factors for the system performance within the tuning range among others are

- varying large signal behaviour of the receivers caused by the variation of the receiver tuning components
- fast increase of oscillator phase noise and by extending the tuning range, the impact on the overall system performance.

In Spectrum ranges with TV broadcast allocations, the tuning range of some PMSE application relates to the bandwidth of one TV channel (6 to 8 MHz) and integer multiples of it.
