Figure 84: Optional SAW Filter Responses for 14 MHz and 28 MHz
Based on the receiver’s high level of integration, the proper IF filter is automatically selected based on the current
mode and bit rate settings of the demodulator. Although manual filter selection is available via the IF Filter Menu on
the front panel LCD, as shown in Figure 85, manual selection is not recommended. In the case of a receiver with
diversity combining enabled, the two channels must have the same IF filter selected for proper operation.

4.4.2.19.3 Phase Noise Comp (PCM/FM Mode Only)
The Phase Noise Comp option, shown in Figure 86, is used to set the Phase Noise Compensation (PNC) value to
On, Off, or Auto. When set to Auto, the RDMS continuously checks and determines which mode (with PNC or
without) has a higher data quality value and automatically sets the unit to that mode. Refer to section 9, Appendix C,
for detailed information about Phase Noise Compensation.
