In case of amplifier faults, the central conductor is grounded forcing the equipment to enter stand-by mode. 7.4 Power Supply Block The TEX1003TFT power supply provides the two main power supplies: 1. Services. This voltage powers elements that do not directly affect the power supply such as the motherboard, panel board and fans. 2. Power supply. This voltage powers the RF power amplifier module and protects the equipment from any sudden fluctuations in the mains voltage.

    • Low-pass filter, which also includes the power meter. In this block there is an RF pickup at approximately -46dB (for the TEX1003TFT model) with respect to the output available on a BNC connector below the transmitter output connector. This pickup is used to assess the characteristics of the carrier, but not those of the upper harmonics.
