An emissions mask function is always defined by a sequence of triplets (x, y = f(x), z) displayed in the emissions mask grid where f(x) stands for the relative emitted power (in dBc) at frequency offset x (expressed in MHz), measured in a reference bandwidth z (expressed in kHz). A full description of the calculation of total emissions is available in ANNEX 6:.

- Red curves: It shows the actual curve of the mask, for given reference bandwidth z, that is:

- Blue curves: it shows the curve normalized in a reference bandwidth of 1 MHz, that is:

The blue curve is aimed to detect potential discontinuities in the definition of transmission mask, and is also the one which is used in actual simulations when integrating the total power of unwanted emissions, in order to overcome possible differences of victim and interferer bandwidths.
