Figure 7. Power Meter Setup (20 mW 500 mW Range).

NOTE

Do not exceed RF power amplifier Maximum Input (+10 dbm).

(5) Set measuring receiver to measure RF power.

(6) Set RF power amplifer gain to 50%. Set signal generator frequency to 10 MHz

and output to -45 dBm. Slowly increase signal generator output and, if necessary, power

amplifier gain for measuring receiver indication listed in table 14 corresponding to 20 mW

range. If TI does not indicate within limits specified in table 14, perform b below.

(7) Repeat technique of (6) above for remaining TI ranges and source outputs listed

in table 14. If TI does not indicate within limits specified in table 14, perform b below.
