Select the frequencies to be used using the Flexible Hopping Definition menu 2. Define the method of generating the basic hopping sequence based on the set of selected frequencies, using the Scrambling Definition sub-menu.
Flexible Hopping Definition Mode Frequencies Selection and Basic Sequence Generation Using the Flexible Hopping Definition Menu The Flexible Hopping Definition menu includes the following options: Define Sub-Bands The Define Sub-Bands option enables defining a new list of sub-bands and/or discrete frequencies. Enter a list of the required sub-bands and/or frequencies, using either sub-bands (f1-f2) or discrete frequencies, e.g. 904-910,915,919-925.
Appendix D - Configuring Hopping Frequencies and Operational Sequences Standard Scrambling This mode is not recommended for sequences with 7 or more channels.
Flexible Hopping Definition Mode The scrambled basic sequence can also be calculated using the formula: Px (j)= {[(j-1)*X]mod(N)}+1 Where: X is the Spanning Factor N is the number of channels in the sequence (modulus) J is the sequence index Example: N=8, X=3 P1(5)={[(1-1)*3}mod8}+1=1 P2(5)={[(2-1)*3}mod8}+1=6 P3(5)={[(3-1)*3}mod8}+1=3 P4(5)={[(4-1)*3}mod8}+1=8 P5(5)={[(5-1)*3}mod8}+1=5 P6(5)={[(6-1)*3}mod8}+1=2 P7(5)={[(7-1)*3}mod8}+1=7 P8(5)={[(8-1)*3}mod8}+1=4 And the basic scrambled sequence is: 1, 4,
Appendix D - Configuring Hopping Frequencies and Operational Sequences Valid values: 1 to Number of Hopping Frequencies minus 1, provided it meets the GCD requirement as described above. It is not recommended to use spanning factors of 1 and N-1, as they result in hopping on consecutive channel (assuming that the available channels are consecutive). In these cases the advantage of using frequency hopping is not fully utilized, since narrow band interference may affect several consecutive hops.
