5.1

Transmission Power

Purpose: To verify that the transmitted output power of the DUT conforms to the standards limit.

Pass Condition: See respective standards document for specifications and pass conditions.

Test Environment: Figure 3 illustrates the transmission power test setup.

Figure 3. Transmission Power Test Setup

Procedure:

Step 1.

Connect the instruments and test board as shown in Figure 3.

Step 2.

Set the EM to unmodulated, continuous TX mode with the appropriate output power level

through SmartRF Studio (see Ref. 10).

Step 3.

Measure the output power level on the spectrum analyzer to confirm the output power

programmed on the EM.
