6.2. AIM+: USING THE SPECTRUM ANALYZER TO

DETECT AND MITIGATE INTERFERENCE

6.2.1 Narrowband interference mitigation

Conﬁguring the notch ﬁlters

When the notch

ﬁ

lters are set to their default auto mode, the receiver performs automatic

interference mitigation of the region of the spectrum aﬀected by interference. In manual
mode, as shown con

ﬁ

gured for Notch1 in Figure 6-3, the region of the aﬀected spectrum is

speci

ﬁ

ed by a center frequency and a bandwidth which is eﬀectively blanked by the notch

ﬁ

lter.
