b) Adjust the spectrum analyzer to give a maximum indication with a frequency scan width of 500 kHz.c) Remove any modulation from the interfering test signal source.d) Set the frequency of the interfering test signal source to within 50 kHz to 100 kHz above the frequency of the transmitter under test. The frequency shall be chosen in such a way that the intermodulation components to be measured do not coincide with other spurious components.e) Adjust the power output of the interfering test signal source to equal the carrier power level of the transmitter under test. This is the power level that was measured in 2.2.1.f) Record the largest third order intermodulation component from the spectrum analyzer as ILVL .g) Record the transmitter under test carrier power level from the spectrum analyzer as CLVL .h) Calculate the intermodulation attenuation as:Intermodulation attenuation = CLVL - ILVLi) Set the frequency of the interfering test signal source to within 50 kHz to 100 kHz below the frequency of the transmitter under test. The frequency shall be chosen in such a way that the intermodulation components to be measured do not coincide with other spurious components.j) Repeat steps e) through h).k) The lesser of the values recorded in steps h) and j) is the intermodulation attenuation.
