9.2.3.1 DESCRIPTION
The RFL 9508 Tx Filter is a plug-in module consisting of two PC boards and two air core inductors. It plugs
into the left side of the RF chassis as shown in Figure 9-2.
The function of the Tx Filter is to filter out harm
onics and noise that is out of the bandwidth of the filter. The
bandwidth of the filter can be set to either 8kHz or 16kHz using two program
m
able jumpers, J1 and J45. The
filter center frequency is tunable from 24kHz to 496kHz using programmable jumpers. The outer edges are
20kHz and 500kHz. The 8kHz bandwidth is used for one or two RF channel operation and the 16kHz bandwidth
is used for three or four RF channel operation.
