Operational Description 6 (14) Radio module TRXBQ900Document-ID: 947603-000Version: A1 Author: SHChecked by: BQApproved by: 4 Operational Description 4.1 Operational Description TRXBQ900 is a module transceiver used for remote control. Power is supplied to the unit with external 3.5-5 V DC power. The 3.3 V system DC voltage is supplied by an internal voltage regulator. The logic unit (CPU) is an 8 bit microcontroller from Microchip running at 19.68 MHz. The radio chip is a narrow band FSK (GFSK) transceiver. The radio protocol is a GFSK modulated signal with data speed of 9.6 kbits/s. Data communication is made through the modules UART data interface. The data is processed by the CPU and clocked into the radio chip as a single data packet. The data consists of maximum 320 bits and is transmitted at a rate of 9.6 kbit/s. There is also an SPI interface where the user can select frequency and other parameters. For more info on the SPI interface see chapter 6. The module can operate in two modes, Receive mode and Transmit mode. Normally the module is in Receive mode. When the first byte of serial data is received in the UART RX buffer, the module will shift to Transmit mode. When all received bytes in the RX buffer have been transmitted, the module will return to Receive mode. The transfer rate to the RX buffer is 19200bps. In Receive mode the data bytes received will be transmitted on the TX-pin with 19200bps. Since the transmission rate over air is 9600bps there will be an idle time between received bytes. The data format is 9600bps, 1 stopbit, parity none.

The EUT was tested stand alone, as a modular device. The test was performed with continuously transmission (100% duty cycle), if not otherwise stated, and with normal modulation. For duty cycle measurements see appendix 2. With the normal duty cycle the duty cycle was measured to 28.06/100.2 ms = 0.121 = 28.0%. The PRF was calculated to PRF = 1/T = 1/100.2 ms = 10 Hz, thus QP-detector was used without any correction for pulse desensitization.
