Tune-Up Procedure 1. Purpose This panel gives the possibility to manage the mobile in the transmit mode. This window includes both: - All the parameters (frequency band, RF channel, RF level to get the desire antenna output power…) The user needs to make the mobile transmitting, - All the parameters needed to define a transmit burst, - All the compensation table to be ableto align the mobile in production. This Tx_commands user guide is describing: - The characteristics of the transmit burst, - All the parameters used in the transmit mode, - The operating mode to make the mobile transmitting 2. General description 2.1. Characteristics of the transmit burst The power levels and the shape of a transmit burst are controlled bythe power amplifier controller integrated in the MT6737 The burst is generated by a 10-bit DAC as shown below: The ramping shapes referenced with the rising edge of Tx-ON (from the Baseband). There are two types of parameters define the transmit burst: the first one define the shapes of the burst, and the second one define the temporal position of the burst. The rising and the falling edge of the transmit burst are determined by a set of 32 DAC code values n = 0 … 31. Tru = TxTRUDefault + △TRU_P + △TRU_T Trd = TxTRD_NBDefault + △TRD_P (for a normal burst). Trd = TxTRD_ABDefault + △TRD_P (for an access burst). 2.2. GPRS Data Transfer GSM mobile phones use a Time Division Multiple Access (TDMA) scheme to transmit data. The
