TEX1002LCD 7. Working Principles 7.1 Panel card The panel board accommodates the microcontroller that runs equipment firmware and all user interface elements (display, LEDs, keys, …). This board is interfaced with other equipment modules via flat cables and provides for power supply, control signals and measurement distribution. 7.2 Main Board The main board performs the following tasks: • Audio and SCA input treatment; • Generation of carrier frequency; • Modulation ; • R.F.
TEX1002LCD The same board also features the “INTERLOCK” BNC connector for disabling the device. By grounding the central pin, the output power is reduced to zero until the connection is removed. When an R.V.R. amplifier is used, this connector is linked to the power amplifier REMOTE or INTERLOCK by means of a BNC-BNC connection. In case of amplifier faults, the central conductor is grounded thus forcing the machine to enter in stand-by mode. 7.
TEX1002LCD This board also features an RF sampling of approximately -46dB RF (for TEX1002LCD model) with respect to the output, which is available on a BNC connector below the transmitter output connector. This sample is useful for verifying the characteristics of the carrier, but not for verifying those of the upper harmonics. 7.6 Bias card The main function of this board is to check and correct the MOSFET polarization voltage of the RF amplifier section.
