Test Procedure:

Below 1GHz test procedure: Refer to KDB 558074 D01, Section 12.1. The EUT is placed on a rotating table 0.8 meters above the ground in a 3-meter semi-anechoic chamber. The table is rotated 360 degrees to find the highest radiation position. The EUT is set 3 meters away from the interference-receiving antenna, which is mounted on a variable-height antenna tower. Antenna height is varied from 1 to 4 meters. For frequencies below 30MHz, antenna height is 1 meter. The rotatable is turned from 0 to 360 degrees. The test-receiver system is set to Peak Detect Function with Maximum Hold Mode. If peak emission is 10dB lower than the limit, testing stops. Otherwise, emissions with less than 10dB margin are re-tested using specified methods.

Above 1GHz test procedure: The test site changes to a fully anechoic chamber, and the table height is increased to 1.5 meters (1 meter for above 18GHz). Tests are performed on the lowest, middle, and highest channels. Radiation measurements are performed in X, Y, Z axis positioning for Transmitting mode, with X-axis positioning found to be the worst case. Procedures are repeated until all frequencies are measured.

Note: 15.35(b), Unless otherwise specified, the limit on peak radio frequency emissions is 20dB above the maximum permitted average emission limit applicable to the equipment under test. This peak limit applies to the total peak emission level radiated by the device.

Radiated Spurious Emission below 1GHz:

During the test, Radiated Spurious Emissions from 30MHz to 1GHz were performed in all modes with all channels. GFSK, Channel 2440MHz was selected as the worst condition. The test data for the worst-case condition is recorded.

Remark:

1) The field strength is calculated by adding the Antenna Factor, Cable Factor & Preamplifier. The basic equation with a sample calculation is as follows: Final Test Level = Receiver Reading + Factor. Factor = Antenna Factor + Cable Factor - Preamplifier Factor.

2) Scan from 9kHz to 25GHz, the disturbance above 18GHz and below 30MHz was very low. As shown in this section, for frequencies above 1GHz, the field strength limits are based on average limits. However, the peak field strength of any emission shall not exceed the maximum permitted average limits specified above by more than 20 dB under any condition of modulation. So, only the peak measurements were shown in the report.
