The measurement is split into two figures: in Figure 13 the unwanted spurious emission for

a frequency below 1 GHz is shown. The measurement is performed setting the instrument in

max. hold with a resolution bandwidth of 100 kHz, as requested in ETSI [2]. In Figure 14 the

unwanted spurious emission for frequencies from 1 GHz to 4 GHz is shown. The

measurement is performed setting the instrument in max. hold with a resolution bandwidth

of 1 MHz, as requested in ETSI [2]. In the two images the mask request from ETSI is also

reported.

The unwanted emissions in the spurious domain of SPIRIT1 comply with ETSI [2] subclause

7.8.
