Overview TRU35 is a high-power, small-size half-duplex digital radio designed by using advanced 32-bit cortex M4 microcontroller technology, wireless transceiver RF technology, and digital communication technology, this radio selects high-quality RF components, excellent EMC and EMI processing, and shell & heat sink integration technology. It has the advantages of high transmission power, long transmission distance, integrated transmission and receiving, simple installation and use, high cost performance, stable and reliable. II. Functions  Receiving and transmitting are integrated in one, half duplex, fast switching  Radio relay function greatly improves the transmission distance TRU35 can send the received data through other frequency points, increasing the communication distance and expanding the signal coverage.  Level 2 surge protection, reverse polarity protection The TRU35 adopts a level 2 surge protection to protect the radio from damage when the instantaneous input voltage or current exceeds the normal range. Even if the positive and negative polars are connected inversely, the radio will not be damaged.  Standing wave detection protection TRU35 adopts standing wave detection protection to prevent damage to the instrument caused by long open and short circuits.  Thermal protection TRU35 can adjust the transmitting power adaptively, automatically reduce the power when the instrument temperature is too high, and automatically increase the power when the instrument temperature decreases, to ensure that the instrument is always in a stable power range, and will not be damaged due to overheating.  Protection- IP67  Without assembly, integrated shell, high overall heat conduction efficiency and good heat dissipation 2  Bluetooth configuration and Bluetooth datalink functionality TRU35 can configure and set its mode, protocol, air interface baud rate, frequency, high or low power through handheld via Bluetooth connection. It can also receive RTK data through Bluetooth and send it out through radio.  Standard 16 channels for transmitting and receiving, users can configure and use according to the situation  Under the condition of high transmission power, the transmission distance can reach 14 kilometers (depend on the base station height and the surrounding environment) III.

Test setup: Test Procedure: The transmitter was placed on a wooden turntable, and it was transmitting into a non-radiating load, which was also placed on the turntable. The measurement antenna was placed at a distance of 3 meters from the EUT. During the tests, the antenna height and polarization as well as EUT azimuth were varied in order to identify the maximum level of emissions from the EUT .The test was performed by placing the EUT on 3-orthogonal axis. The frequency range up to teeth harmonic of the fundamental frequency was investigated. Remove the EUT and replace it with substitution antenna.
