350-Watt Digital VHF LB Transmitter Chapter 3, Installation and Setup Procedure
DT325B, Rev. 0 3-13
Table 3-14: Menu 40-2 - Transmitter Set-up: Model Select Screen
This screen is used to specify which components are expected to be part of the system.
By specifying the model number, the transmitter control firmware knows which
components should be installed and it will be able to display faults for components that
are not properly responding to system commands.
Table 3-15: Menu 40-3 - Transmitter Set-up: Upconverter Channel Select Screen
The choices of this screen are to the standard UHF / VHF channels. The + and – buttons
change the desired channel of the transmitter. The PLL frequency is set for custom
Offsets within the upconverter frequency. Any change to the channel is immediately set
to the Upconverter Frequency Synthesizer PLL circuit.
Table 3-16: Menu 40-5 - Transmitter Set-up: Serial Address Screen
This screen allows the user to set the serial address of the transmitter. The default
address is 5. This value and all other set-up parameters are stored in non-volatile
memory.
Table 3-17: Menu 40-6 - Transmitter Set-up: System Forward Power Calibration
This screen is used to adjust the calibration of the system's forward power. A symbol
placed under the '6' character is used to show major changes in the calibration value.
When the calibration value is at full value, the character will be full black. As the value
decreases, the character pixels are gradually turned off. The calibration value is a value
between 0 and 255 but the calibration value symbol only has 40 pixels. Therefore small
changes in actual calibration value may not affect the symbol's appearance.
Table 3-18: Menu 40-9 - Transmitter Set-up: System Reflected Power Calibration
This screen is used to adjust the calibration of the system's reflected power. Again a
calibration value symbol is used for this screen as on the previous screens.
