a. Performance Check
(1) Connect power sensor module to measuring receiver POWER REF output.
(2) Zero and Calibrate the power sensor.
(3) Disconnect the measuring receiver power sensor module from the POWER REF
output connect it to the TI RF OUTPUT.
(4) Press TI keys as listed in (a) through (e) below:
SYSTEM, Reset.
(a)

(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
Max limit (dB)
