4. CHANNEL SELECTION
The FCC has allocated 83.5 MHz of spectrum in the 2.4 GHz band where the TRACER 6410 operates, and
125 MHz of spectrum in the 5.8 GHz band where the TRACER 6420 operates. Figure 1 and Figure 2
illustrates the bandwidth division.
Figure 1. 2.4 GHz Bandwidth Division
Figure 2. 5.8 GHz Bandwidth Division
To designate the utilization of the Industrial, Scientific, and Medical (ISM) bandwidth, there are two
different frequency plans, labeled A and B. The letter of each frequency plan setting is preset by the factory
and refers to the physical configuration of the diplexer filter inside the chassis. Each frequency plan is then
divided into three band plans (1, 2, or 3). The band plans must be the same for the local and remote
TRACER 64x0. For example, the transmitter at one end of the link will transmit in band plan 1 of frequency
plan A (the lower portion of the spectrum) and receive in band plan 1 of frequency plan B (the upper
portion). Consequently, the receiver at the other end should receive in band plan 1 of frequency plan A (the
lower portion) and transmit in band plan 1 of frequency plan B (the upper portion).
The letter of the frequency plan (A or B) must be different on both ends, and the number of the band plan (1,
2, or 3) must be the same on both ends. The default band plan configuration for the TRACER 64x0 is band
plan 1.
The frequency plan (A or B) of the unit may be changed in the field, if necessary, by rewiring the internal
diplexer. Contact Technical Support (see Warranty, Customer Service, Product Support Information, and
Training on page 7) for more information on this procedure.
