SECTION 5: DETECTING SOPHISTICATED TRANSMITTERS

PEAK DISPLAY EXAMPLES
Below are various examples of certain types of transmitters when viewed using the Peak
display options.
Pager Example
While a pager is certainly not a sophisticated transmitter, it is provided mainly to explain
the concept of the Peak Display mode. This is a simple paging transmission band with 3
primary channels. The channel in the middle is transmitting while the two outside
channels were temporarily silent. This difference Invert display was chosen as an example
because it provides an easy means of visually separating the Peak, the Real-time, and the
difference display.
