8. Calibration Checks
a. Performance Check
(2) Set the TI Power range switch to first setting in table 3.
(3) Turn RF power on and slowly adjust the output power to match the Power Meter
reading in table 3.
CAUTION
Do not allow RF Power Amplifier output to exceed the TI
Power range switch setting selected.
(4) Once the Power Meter reading is achieved and stable, record the TI reading in
the corresponding column of table 3. Reduce RF power to minimum and set source to
standby.
(5) Calculate and record the difference between the Power Meter reading and the TI
recorded value; the difference must be within the tolerance listed in table 3.
(6) Repeat steps (3) through (5) above for each of the remaining TI Power range
switch settings in table 3 corresponding to Frequency being tested.
