                                 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.

         minimum gauge wire gauge of 20 AWG
