Figure 7-35 Frequency Hopping
As indicated in Figure 7-35, the frequency hopping function is set through “Hopping
Frequency Point+Frequency Hopping Range”. Specific frequency hopping is: Hopping
Frequency Point-Frequency Hopping Range, Hopping Frequency Point+Frequency
Hopping Range. Up to three frequency hopping ranges can be set. When their hopping
ranges are all set as 0, corresponding frequency function is disabled.
When the frequency hopping function is enabled and if the set frequency is in the
frequency hopping range, then the finally set frequency will be “Hopping Frequency
Point-Frequency Hopping Range” during the rising of the set frequency or will be
“Hopping Frequency Point+Frequency Hopping Range” during the decrease of the set
frequency.
Different frequency hopping ranges may be superposed (see the frequency hopping
ranges 1 and 2 in Figure 7-35) and the final frequency hopping range is (Hopping
Frequency Point 1-Frequency Hopping Range 1, Hopping Frequency Point 2+Frequency
Hopping Range 2)
