Control Chnl TX Frequency (P25 Trunk submenu)
Set the base station control channel generate frequency directly in MHz using the ▲▼ (Up/Down), and
◄► (Left/Right) keys, numeric keypad, and spin knob. The Control Chnl field displays the closest
corresponding Control Channel number as determined by the Band Plan Table, which may result in a
negative channel number if the specified frequency is less than the Band Plan Table’s Base Frequency.
Note: The CCTx setting is updated accordingly, or can be used to enter the channel number instead.
Control Chnl TX Frequency = Radio Control Channel TX Frequency - Transmit Offset
CCTx Channel (P25 Trunk submenu)
Set the Control Channel number from 0 to 4095 using the ▲▼ (Up/Down), and ◄► (Left/Right) keys,
numeric keypad, and spin knob. The CCTx field displays the corresponding base station Control Channel
generate frequency as determined by the Band Plan Table. Note: The Control Chnl TX Frequency setting
is updated accordingly, or can be used to enter the frequency directly.
Radio Generate Frequency = Base Fre Transmit Channel Spacing * CCTx Channel #
Voice Chnl TX Frequency (P25 Trunk submenu)
Set the base station voice channel generate frequency directly in MHz using the ▲▼ (Up/Down), and
◄► (Left/Right) keys, numeric keypad, and spin knob. The Voice Chnl field displays the closest
corresponding Voice Channel number as determined by the Band Plan Table, which may result in a
negative channel number if the specified frequency is less than the Band Plan Table’s Base Frequency.
Note: The VCTx setting is updated accordingly, or can be used to enter the channel number instead.
Voice Chnl TX Frequency = Radio Voice Channel TX Frequency - Transmit Offset
VCTx Channe (P25 Trunk submenu)
Set the Voice Channel number from 0 to 4095 using the ▲▼ (Up/Down), and ◄► (Left/Right) keys,
numeric keypad, and spin knob. The VCTx field displays the corresponding base station Voice Channel
generate frequency as determined by the Band Plan Table. Note: The Voice Chnl TX Frequency setting
is updated accordingly, or can be used to enter the frequency directly.
Radio Generate Frequency = Base Fre Transmit Channel Spacing * VCTx Channel #
BER Test (P25 Trunk submenu)
Select Stop and Start for the BER test. Pressing Start displays a new P25 Trunk BER screen and submenu;
Stop ends the testing and restores the default screen/submenu. When running, trunking operation ceases
and BER specific setting and display fields are available. Modulation Type, Modulation Mode, and Test
Pattern settings are provided for testing receivers of base stations and radios that have been put into test
mode with RSS. Note: More in-depth BER testing of radio’s can be done in the R8100’s PROJECT 25
conventional test mode option. The Test Pattern setting, BER Test status, and calculated BER percentage
(see Figure 3.2.8.5-3) are provided for testing transmitters of base stations and radios that have been put
into test mode with RSS. Modulation Fidelity, Symbol Deviation, and Symbol Rate Error measurements
are also available for the transmission signal being tested; for explanations see section 2.2.7.3 for the
PROJECT 25 Test Mode (Conventional). BER test Monitor and Generate frequencies are specified via
the RF Zone rather than the Band Plan Table. The BER specific vertical soft keys are as follows:
