Spectral mask Sample Clauses

Spectral mask. Figure 12 shows Tx output spectrum with modulated signal. In this measurement, modulated signals are provided from digital baseband block. The center channel frequency is set to 60.48 GHz, which is a center frequency of channel number 2. Compared with a spectrum mask, which is shown in black solid line in Figure 12, the output signal of the 60 GHz module matches with the requirements specified in IEEE 802.15.3e. In IEEE 802.15.3d, the shape of the spectrum mask is same as defined in IEEE 802.15.3e with a difference of center frequency. So, we can expect that the output signal from the ThoR system will compliant with IEEE 802.15.3d specification with an appropriate up conversion.
