a. Performance Check
(1) Connect power sensor module to measuring receiver CALIBRATION RF
POWER OUTPUT.
(2) Calibrate and save the calibration of the power sensor.
(3) Disconnect the measuring receiver power sensor module from
the
CALIBRATION RF POWER OUTPUT and connect it to the TI RF OUTPUT.
(4) Press TI keys as listed in (a) through (e) below:
(a)
SYSTEM, Reset.
(b)
OUTPUT off.
(c)
Level Control, L0, Edit L0, 1, 1, and dB.
(d)
OUTPUT on.
(e)
Frequency Control, F0, Edit F0, 1, and GHz.
(5) Using measuring receiver and RF power techniques in Log Mode, sweep the TI
from 2 GHz to 18 GHz in 1 GHz steps, and record the highest and lowest levels.
(6) Calculate the flatness using the formula below. The flatness will be less than or
equal to the maximum limit listed in table 4.
Flatness = (highest lowest)/ 2
