For calculating the image rejection ratio in ADS, we give two signals as system input, "original signal" and the "image signal + 10Khz ".

In my receiver I am down converting my signal to 20Mhz. So for calculating IRR, What i have to do ?
Shall i take peek difference of "20Mhz" and "20Mhz +10Khz" or 0Hz and 10Khz?
