The 9102 comes with preinstalled communication systems. For a listing
of all the channel systems preinstalled on the 9102 refer to “Prein-
stalled systems on the 9102” on page 359.
Setting up a new
communication system
A new communication system can be defined in terms of frequency
range, channel bandwidth and spacing, and channel numbering; chan-
nels can then be addressed easily by their channel number rather than
the carrier or center frequency. You can set up a new communication
system as follows:
1 In the main menu, select
Ch. System.
The Channel System menu appears.
2Press
First Channel and enter the first channel number in use by
the system, then close the input field by pressing E
NTER.
3Press
Last Channel to enter the number of the last channel in use
by the system; close the input field by pressing E
NTER.
4Press
Channel Width to change the measurement bandwidth;
ensure to select the right unit (e.g. kHz).
5 Select the
Channel Spacing softkey, enter the spacing between
channel numbers and close the input field by pressing the enter
key for the appropriate frequency unit.
6 Press the
1st Ch. Center softkey and enter the carrier frequency for
the first channel in use (channel number defined with the first
softkey). Close the input field using the enter key for the appro-
priate unit (e.g. MH
Z).
7 For occupied bandwidth (OBW) measurements, select
% OBW and
enter the percentage value. Confirm the value by pressing E
NTER.
8 Select
System Memory > Store System, enter a new name for the
system and press E
NTER.
NOTE
Apart from the channel width the parameters for preinstalled config-
uration systems cannot be modified.
NOTE
Existing systems cannot be overwritten; you must delete the old sys-
tem first.
If you delete a predefined system that is delivered with the 9102, it
can be restored as depicted in section “Undeleting default commu-
nication systems” on page 89.
