24-4.3.2 RF Zone
This zone contains general RF information
specifically related to the Project 25
Trunking mode of operation.
selection for both the control channel and the
voice channel is made in this zone. The RF
zone provides for user selection of the
channels and frequencies. A description of
each field contained within the RF Zone is as
follows.
Band
This entry allows the user to select the RF
Band for a particular test. These include the
following bands:
800 MHz
851.00625 MHz – 876.59375 MHz with a -
45 MHz offset. Channel plan #1.
700 MHz
762.00625 MHz – 787.59375 MHz with a
+30 MHz offset. Channel plan #2.
UHF/VHF
User defined channel plan. The channel plan
range is 1 thru 16. This can also be used to
define non-standard 700 MHz channel plans.
CCTx
Control Channel Generate Frequency
This parameter allows the user to enter the
control channel frequency in MHz.
Ch Control Channel Number
This parameter allows the user to enter the
control channel number. The 800 MHz band
allows for channel numbers 0 to 4094 which
correspond to a frequency range of 851.00625
to 876.59375 MHz respectively.
VCTx
Voice Channel Generate Frequency
This parameter allows the user to enter the
Channel
voice channel generate frequency in MHz.
Ch Voice Channel Number
This parameter allows the user to enter the
voice channel number. The 800 MHz band
allows for channels 0 to 4094 which
correspond to a frequency range of 851.00625
to 876.59375 respectively.
Mon
This field allows the user to select the
attenuation and port for the received signal.
Attenuation is softkey selectable and can be
set to 0, 20, or 40dB. The port is softkey
selectable to RF I/O or ANT.
Gen
This field allows output, level setting and
generate port selection. The output level can
be entered using the keypad or the tuning
knob. The port is softkey selectable to Gen
Out or ANT. The output level varies based on
the generate port selection as follows:
Gen out 0 - -80dB
RF/IO -50 – 130dB
24-4.3.2.1
The UHF/VHF allows the user to define a
channel plan that is different than the
predefined channel plans (i.e., 800/700 MHz).
This definition is used to determine channel
number mappings. A description of each field
in the UHF/VHF Config is as follows:
