The data and results referenced in this document are true and accurate. The reader is cautioned that
there may be errors within the calibration limits of the equipment and facilities. The measurement
uncertainty was calculated for all measurements listed in this test report acc. To CISPR 16 – 4
“Specification for radio disturbance and immunity measuring apparatus and methods – Part 4:
Uncertainty in EMC Measurements” and is documented in the LCS quality system acc. To DIN EN
ISO/IEC 17025. Furthermore, component and process variability of devices similar to that tested may
result in additional deviation. The manufacturer has the sole responsibility of continued compliance of
the device.

1.7 Description of Test Modes
The FM Transmitter is powered by a battery which is DC 12V. In the audio port and MIC port give a 2.5
kHz tone at a level 16 dB higher than that required to produce a frequency deviation of 75 KHz and
make it works in TX mode (88.1 MHz, 98.0 MHz and 107.9 MHz).
Worst-case mode and channel used for 9 KHz-1000 MHz radiated emissions was the mode and
channel with the highest output power, that was determined to be TX.
Radiated emission performed at both DC power supply and AC power adapter, recorded worst case;
AC conducted emission only perform at power adapter mode, pre-check both at AC 120V/60 Hz and
AC 240V/50Hz. Recorded worse case;

measurements.
According to its specifications, the EUT must comply with the requirements of the Section 15.207,
15.209, 15.239 under the FCC Rules Part 15 Subpart C.

2.3 General Test Procedures
2.3.1 Conducted Emissions

The EUT is placed on the turntable, which is 0.8 m above ground plane. According to the requirements
in Section 6.2.1 of ANSI C63.10-2013 Conducted emissions from the EUT measured in the frequency
range between 0.15 MHz and 30MHz using Quasi-peak and average detector modes.

2.3.2 Radiated Emissions

The EUT is placed on a turn table 0.8 meter above ground for below 1GHz and 1.5m for above 1GHz.
The turntable 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 maximum emissions, exploratory radiated emission
measurements were made according to the requirements in Section 6.3 of ANSI C63.10-2013.
