4.1 Principle of Configuration Selection

Radio Spectrum:

The equipment under test (EUT) was configured at its highest power output in

order to measure its highest possible radiation and conducted level. The test modes were adapted

accordingly in reference to the instructions for use.

Emission: The equipment under test (EUT) was configured to measure its highest possible radiation level. The test modes were adapted accordingly in reference to the instructions for use.

4.2 Test Operation and Test Software
Test operation refers to test setup in chapter 5. All tests were performed according to the procedures in ANSI C63.10: 2013 and ANSI C63.4: 2014.

4.3 Countermeasures to Achieve EMC Compliance
The test sample which has been tested contained the noise suppression parts as described in the Technical Construction File (TCF). No additional measures were employed to achieve compliance.

Pass

According to the manufacturer declared, the EUT has two PIFA antenna, the directional gain of antenna is 2.58 dBi(ANT1) and 2.72 dBi(ANT2), which that use of a non-standard antenna connector and no consideration of replacement. Therefore, the EUT is considered sufficient to comply with the provision.
Antennas 1 and 2 are uncorrelated, and MIMO antenna gain is the maximum of the two antennas.

Therefore, the EUT is considered sufficient to comply with the provision.
