(2) Connect sensor module to measuring receiver CALIBRATION RF
POWER OUTPUT.
(3) Connect TI RF OUTPUT to measuring receiver power sensor.
(4) Press TI keys as listed in (a) through (e) below.
(a)
RCL 0.
(b)
Adjust OUTPUT LEVEL for -3 dB.
(c)
ALC INTERNAL on.
(d)
RF OUTPUT on.
(e)
FREQUENCY, 2, GHz.
(5) Using measuring receiver and tuned level 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 8.
Flatness = (highest lowest) / 2
Start frequency
