Figure 79: Advanced Menu, Sync Measured Bit Rate Selection
To apply the measured bit rate, scroll to the Sync Bit Rate option to highlight it. Then press the Enter key on the
front panel keypad. The displayed bit rate value will be set as the new bit rate.
Note:
The measured bit rate will be set whether it is accurate or not. For proper operation, ensure that the receiver
indicates it is locked (green padlock) prior to using the Sync Bit Rate function.
4.4.2.19.2 IF Filter
The receiver’s integrated
IF filter module, shown in Figure 80, includes eight (8) SAW filters, ranging in bandwidth
from 250 kHz to 40 MHz in approximately one-octave steps. The standard eight filters are 250 kHz, 500 kHz, 1
MHz, 2 MHz, 4.5 MHz, 10 MHz, 20 MHz, and 40 MHz. These filters serve as anti-aliasing filters ahead of the A/D
converter in the demodulator itself. In addition, they can provide an added measure of adjacent channel interference
rejection.
