4.3 ATTENUATOR LINEARITY TESTS
4.3.1 Set the TI controls as follows:
FREQUENCY MHz switches to
MASTER MOD control to
108.000 MHz
UNCAL [fullyccw (0)]
Output attenuator control to
-6 dBm
4.3.2 Connect the signal generator calibrator sensor module input to the TI RF output connector.
4.3.3 Press the signal generator calibrator INSTR PRESET key (Blue key, AUTOMATIC OPERATION
key), and ensure that the signal generator calibrator is in the FREQ measurement mode and tunes to the TI
FREQUENCY MHz switches setting. Set the signal generator calibrator for TUNED RF LEVEL
measurements with log (dBm) display, enter 39.9 SPCL, and then press the CALIBRATE key.
4.3.4 Set the TI output attenuator control to each of the following settings. At each setting, verify that the
signal generator calibrator indicates within the tolerance limits listed.
