Spurious Emissions

Purpose: To verify that the conducted spurious emissions are within limits.

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

Test Environment: Figure 10 illustrates the spurious emissions test setup.

Figure 10. Spurious Emissions Test Setup

Procedure:

Step 1.

Connect the instruments and test board as shown in Figure 10.

Step 2.

Set the EM to continuous TX mode with random modulated data through SmartRF Studio.

Set the center frequency to the desired channel frequency.

Step 3.

Measure spurs from the minimum limit to the maximum limit of the spectrum analyzer.

Note that different spectrum analyzers have different maximum frequencies. Up to 25 GHz is more

than sufficient.
