3  Intermodulation response rejection
 (1) In this instrument, intermodulation response rejection means the measure of the ability of a radiocommunications receiver to receive a wanted signal in the presence of two or more unwanted signals with a specific amplitude and frequency relationship to the wanted signal frequency.

 (2) An intermodulation response rejection greater than or equal to the following values for each out-of-band signal is required:

Receiver Occupied Bandwidth   Frequency offsets from the upper and lower frequency limit of the spectrum licence receiver  Intermodulation performance requirement (dB)
 20 MHz                      ≥ 5 MHz                                                                                      44 dB
≥ 20 MHz                      37 dB

Note: The values in the table above are the ratio between the received unwanted signal power at the defined frequency offset and the receiver's sensitivity level.
