The “main” frequencies are defined by the Start Frequency and Main Step, using
the formula F(N) =Start Frequency + N*Main Step (F(0) = Start Frequency, F(1) =
Start Frequency + Main Step,...). End Frequency is the upper limit.
The Intermediate Step Mask can be used to define additional frequencies using a
finer resolution. The Intermediate Step Mask includes up to 8 entries that include
numbers from 1 to 8 (or none). The intermediate steps are defined as follows:
For example, the Scan step Mask 1,2,5 means that the scanned frequencies are:
Start Frequency, Start Frequency + 125 KHz, Start Frequency + 500 KHz, Start
Frequency +N*Main Step, Start Frequency +N*Main Step + 125 KHz, Start
Frequency +N*Main Step + 500 KHz (N=1, 2,...). End Frequency is the upper limit
for the scanned frequencies).
The Frequency Scanning menu includes the following options:

Table 4-6: Intermediate Step Mask
Number included in Mask Effect on scanned frequencies set
None Only Start Frequency + N*Main Step [F(1), F(2)....F(N)]
1 Start Frequency, Start Frequency + N*Main Step [F(0)F(1), F(2)....F(N)]
2 Start Frequency + N*Main Step + 125 KHz (Start + 125 KHz is scanned only if 1
is included in mask)
3 Start Frequency + N*Main Step + 250 KHz (Start + 250 KHz is scanned only if 1
is included in mask)
4 Start Frequency + N*Main Step + 375 KHz (Start + 375 KHz is scanned only if 1
is included in mask)
5 Start Frequency + N*Main Step + 500 KHz (Start + 500 KHz is scanned only if 1
is included in mask)
6 Start Frequency + N*Main Step + 625 KHz (Start + 625 KHz is scanned only if 1
is included in mask)
7 Start Frequency + N*Main Step + 750 KHz (Start + 750 KHz is scanned only if 1
is included in mask)
8 For a bandwidth of 3.5 MHz: Start Frequency + N*Main Step + 875 KHz (Start +
875 KHz is scanned only if 1 is included in mask)
For a bandwidth of 5 MHz: Start Frequency + N*Main Step + 1250 KHz (Start +
1250 KHz is scanned only if 1 is included in mask)
