There is no special accessory used while test was conducted.
The EUT configuration for testing is installed on RF field strength measurement to meet the
Commissions requirement and operating in a manner which intends to maximize its emission
characteristics in a continuous normal application.
An engineering test mode (software/firmware) that applicant provided was utilized to manipulate the EUT into transmit, selection of the test channel, and modulation scheme.
The EUT is a placed on as turn table which is 0.8 m above ground plan. Conducted emissions from the EUT measured in the frequency range between 0.15 MHz and 30MHz,. The
CISPR Quasi-Peak and Average detector mode is employed according to §15.207. The two
LISNs provide 50 ohm/ 50uH of coupling impedance for the measuring instrument. Both
lines of the power mains connected to the EUT were checked for maximum conducted interference.
The EUT is a placed on as turn table. For emissions testing at or below 1 GHz, the table
height shall be 0.8 m above the reference ground plan. For emission measurements above
1 GHz, the table height shall be 1.5 m. The turn table shall rotate 360 degrees to determine
the position of maximum emission level. EUT is set 3m away from the receiving antenna
which varied from 1m to 4m to find out the highest emission. And also, each emission was
to be maximized by changing the polarization of receiving antenna both horizontal and vertical. In order to find out the max. emission, the relative positions of this transmitter (EUT)
was rotated through three orthogonal axes and measurement procedures for electric field
emissions above 1 GHz the EUT measurement is to be made “while keeping the antenna in
the ‘cone of radiation’ from that area and pointed at the area both in azimuth and elevation,
with polarization oriented for maximum response.” is still within the 3dB illumination BW of
the measurement antenna.
The spectrum analyzer offset is derived from RF cable loss 1.1dB.

8. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical.
9. Repeat above procedures until all frequency of the interest measured were complete.
10.5 Field Strength Calculation
The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the Amplifier Gain and Duty Cycle Correction Factor (if any) from the measured reading.
The basic equation with a sample calculation is as follows:
The limit of the emission level is expressed in dBuV/m, which converts 20*log(uV/m)
