4 TEST RESULTS

4.1   TRANSMITTER SPURIOUS RADIATED EMISSIONS

Standard      FCC Part 15 Subpart C

The test was performed according to:
ANSI C63.10

       4.1.1TEST DESCRIPTION

The test set-up was made in accordance to the general provisions of ANSI C63.10 in a typical
installation configuration. The Equipment Under Test (EUT) was set up on a non-conductive
table 1.0 x 2.0 m² in the semi-anechoic chamber. The influence of the EUT support table that
is used between 30–1000 MHz was evaluated.
The measurement procedure is implemented into the EMI test software EMC32 from R&S.
Exploratory tests are performed at 3 orthogonal axes to determine the worst-case orientation
of a body-worn or handheld EUT. The final test on all kind of EUTs is also performed at 3 axes.
A pre-check is performed while the EUT is powered from a DC power source.

1. Measurement up to 30 MHz
The Loop antenna HFH2-Z2 is used.

Step 1: pre measurement
       •Anechoic chamber
       •Antenna distance: 3 m
       •Detector: Peak-Maxhold
       •Frequency range: 0.009 - 0.15 MHz and 0.15 – 30 MHz
       •Frequency steps: 0.05 kHz and 2.25 kHz
       •IF–Bandwidth: 0.2 kHz and 9 kHz
       •Measuring time / Frequency step: 100 ms (FFT-based)
Intention of this step is, to determine the radiated EMI-profile of the EUT. Afterwards the
relevant emissions for the final measurement are identified.

Step 2: final measurement
For the relevant emissions determined in step 1, an additional measurement with the following
settings will be performed. Intention of this step is to find the maximum emission level.
       •Open area test side
       •Antenna distance: according to the Standard
       •Detector: Quasi-Peak
       •Frequency range: 0.009 – 30 MHz
       •Frequency steps: measurement at frequencies detected in step 1
       •IF–Bandwidth: 0.2 - 10 kHz
       •Measuring time / Frequency step: 1 s


2. Measurement above 30 MHz and up to 1 GHz

Step 1: Preliminary scan
This is a preliminary test to identify the highest amplitudes relative to the limit.
Settings for step 1:
- Antenna distance: 3 m
- Detector: Peak-Maxhold / Quasipeak (FFT-based)

TEST REPORT REFERENCE: MDE_LESSW_1701_FCCa                                             Page 13 of 29


- Frequency range: 30 – 1000 MHz
- Frequency steps: 30 kHz
- IF–Bandwidth: 120 kHz
- Measuring time / Frequency step: 100 ms
- Turntable angle range: –180° to 90°
- Turntable step size: 90°
- Height variation range: 1 – 3 m
- Height variation step size: 2 m
- Polarisation: Horizontal + Vertical
Intention of this step is, to determine the radiated EMI-profile of the EUT. Afterwards the
relevant emissions for the final measurement are identified.

Step 2: Adjustment measurement
In this step the accuracy of the turntable azimuth and antenna height will be improved. This is
necessary to find out the maximum value of every frequency.
For each frequency, which was determined the turntable azimuth and antenna height will be
adjusted. The turntable azimuth will slowly vary by ± 45° around this value. During this action,
the value of emission is continuously measured. The turntable azimuth at the highest emission
will be recorded and adjusted. In this position, the antenna height will also slowly vary by ±
100 cm around the antenna height determined. During this action, the value of emission is
also continuously measured. The antenna height of the highest emission will also be recorded
and adjusted.
- Detector: Peak – Maxhold
- Measured frequencies: in step 1 determined frequencies
- IF – Bandwidth: 120 kHz
- Measuring time: 100 ms
- Turntable angle range: ± 45 ° around the determined value
- Height variation range: ± 100 cm around the determined value
- Antenna Polarisation: max. value determined in step 1

Step 3: Final measurement with QP detector
With the settings determined in step 3, the final measurement will be performed:
EMI receiver settings for step 4:
- Detector: Quasi-Peak (< 1 GHz)
- Measured frequencies: in step 1 determined frequencies
- IF – Bandwidth: 120 kHz
- Measuring time: 1 s

After the measurement a plot will be generated which contains a diagram with the results of
the preliminary scan and a chart with the frequencies and values of the results of the final
measurement.

3. Measurement above 1 GHz
The following modifications apply to the measurement procedure for the frequency range
above 1 GHz:
Step 1:
The Equipment Under Test (EUT) was set up on a non-conductive support (tilt device) at 1.5 m
height in the fully-anechoic chamber.
All steps were performed with one height (1.5 m) of the receiving antenna only.
The EUT is turned during the preliminary measurement across the elevation axis, with a step
size of 90 °.
The turn table step size (azimuth angle) for the preliminary measurement is 45 °.
Step 2:




TEST REPORT REFERENCE: MDE_LESSW_1701_FCCa                                          Page 14 of 29


Due to the fact, that in this frequency range the test is performed in a fully anechoic room, the
height scan of the receiving antenna instep 2 is omitted. Instead of this, a maximum search
with a step size ± 45° for the elevation axis is performed.
The turn table azimuth will slowly vary by ± 22.5°.
The elevation angle will slowly vary by ± 45°
EMI receiver settings (for all steps):
- Detector: Peak, Average
- IF Bandwidth = 1 MHz
Step 3:
Spectrum analyser settings for step 3:
- Detector: Peak / Average
- Measured frequencies: in step 1 determined frequencies
- IF – Bandwidth: 1 MHz
- Measuring time: 1 s

Sample calculation

ULISN (dB µV) = U (dB µV) + Corr. (dB)
U = Receiver reading
LISN Insertion loss = Voltage Division Factor of LISN
Corr. = sum of single correction factors of used LISN, cables, switch units (if used)
Linear interpolation will be used for frequencies in between the values in the table.

Sample calculation

E (dB µV/m) = U (dB µV) + AF (dB 1/m) + Corr. (dB)
U = Receiver reading
AF = Antenna factor
Corr. = sum of single correction factors of used cables, switch unit, distance correction, amplifier (if applicable)
distance correction = -40 * LOG (dLimit/ dused)
Linear interpolation will be used for frequencies in between the values in the table.

Sample calculation

E (dB µV/m) = U (dB µV) + AF (dB 1/m) + Corr. (dB)
U = Receiver reading
AF = Antenna factor
Corr. = sum of single correction factors of used cables, switch unit, distance correction, amplifier (if applicable)
Linear interpolation will be used for frequencies in between the values in the table.
Table shows an extract of values.
