Tune Up Procedure GMSG01 requires no Frequency tunes. The crystal is a TCXO qualified in operating range at time of manufacture. Power levels are set as below. 2.3.2 Power The output power shall have two settings selectable by a discrete input to the board, (sampled during power-up), or by command via the serial port. A jumper shall be included on the board to indicate the source of the control. If the jumper setting corresponds to the discrete input control, the discrete input PWR_LVL is sampled during power up to indicate the output power level. Discrete Control Setting Power Setting (Sampled at power-up) Open Low Ground High If the jumper setting corresponds to a serial control, the power level is set according to a value set in the EEPROM. Serial port commands (See Error! Reference source not found. ) can modify this EEPROM value. The output power on a 50 ohms load after the power amplifier shall be according to Table 1, Output Power Discrete Control Setting Avg Power (During 1.28 s) High 22dBm +/- 2 dB Low 18 dBm +/- 2 dB Table 1, Output Power The power tolerances shall include the temperature and voltage variations as well as the manufacturing tolerances. The power measurement shall be made in a 5 MHz bandwidth centered on the carrier frequency. Closed loop power control should not be required.

I/O Connector and Power/Ground connectors may be combined. 9.1 I/O & Power Connector Description RS232 connection for control and test Discrete control pins for test I/O Pins Power pins Connector TBD Mating Connector TBD (TOP VIEW) 2 4 6 8 10 2 4 2 4 2 4 2 4 2 4 1 3 5 7 9 1 3 1 3 1 3 1 3 1 3 J2 J3 J4 J5 J6 J7 J2-1 POWER IN J5-1 NO PIN J2-2 POWER IN J5-2 NO PIN J2-3 GROUND J5-3 NO PIN J2-4 GROUND J5-4 NO PIN J2-5 DIGITAL INPUT 1 J2-6 DIGITAL INPUT 2 J6-1 POWER LEVEL J2-7 SERIAL TX (INPUT) J6-2 GROUND J2-8 RTS (INPUT) J6-3 POWER LEVEL OVERRIDE J2-9 SERIAL RX (OUTPUT) J6-4 GROUND J2-10 CTS (OUTPUT) J7-1 RTC EXTERNAL POWER IN J3-1 NO PIN J7-2 GROUND J3-2 NO PIN J7-3 LED POWER J3-3 NO PIN J7-4 LED CONTROL J3-4 NO PIN J4-1 TEST INPUT 1 J4-2 TEST INPUT 2 J4-3 VDIG (ICP - NOT INSTALLED IN PRODUCTION) J4-4 uC RESET (ICP - NOT INSTALLED IN PRODUCTION)

Notes: • LED_GND may be connected to board ground. • The cable length between the I/O connector and the DTE will not exceed 20 cm • Unused pins of the connector will be left unconnected Note: • The OEM integrator will keep the power cable length to less than 20 cm with a minimum gauge wire gauge of 20 AWG
