If a signature pops up for a few seconds then
disappears and never comes on again, it is quite likely
that this was a false positive.
Tracking Down Transmitters
Chanalyzer Pro’s waterfall view uses colors to map high amplitude points over time. This allows anyone with a
spectrum analyzer to track down devices by watching amplitude changes over time. While walking around, the
colors change to yellows and reds when a user is approaching the transmitting device.

In the image to the right we can see that the person
performing this site survey walked right by a
transmitting device. The amplitude levels of a
transmitter increase and decrease. In the waterfall
view, it looks like a bluish vertical line turning red.
