Description of the test setup
Typically, the calibrations of the test apparatus are commissioned to and performed by an accredited calibration
laboratory. The calibration intervals are determined in accordance with the DIN EN ISO/IEC 17025. In addition to
the external calibrations, the laboratory executes comparison measurements with other calibrated test systems
or effective verifications. Weekly chamber inspections and range calibrations are performed. Where possible, RF
generating and signaling equipment as well as measuring receivers and analyzers are connected to an external
high-precision 10 MHz reference (GPS-based or rubidium frequency standard).
In order to simplify the identification of the equipment used at some special tests, some items of test equipment
and ancillaries can be provided with an identifier or number in the equipment list below (Lab/Item).

6.1
Shielded semi anechoic chamber
The radiated measurements are performed in vertical and horizontal plane in the frequency range from 30 MHz
to 1 GHz in semi-anechoic chambers. The EUT is positioned on a non-conductive support with a height of 0.80
m above a conductive ground plane that covers the whole chamber. The receiving antennas are conform to
specifications ANSI C63. These antennas can be moved over the height range between 1.0 m and 4.0 m in order
to search for maximum field strength emitted from EUT. The measurement distances between EUT and receiving
antennas are indicated in the test setups for the various frequency ranges. For each measurement, the EUT is
rotated in all three axes until the maximum field strength is received. The wanted and unwanted emissions are
received by spectrum analyzers where the detector modes and resolution bandwidths over various frequency
ranges are set according to requirement ANSI C63.
Measurement distance: tri-log antenna 10 meter
FS = UR + CL + AF
(FS-field strength; UR-voltage at the receiver; CL-loss of the cable; AF-antenna factor)
Example calculation:
FS [dBµV/m] = 12.35 [dBµV/m] + 1.90 [dB] + 16.80 [dB/m] = 31.05 [dBµV/m] (35.69 µV/m)

Sequence of testing
7.1
Sequence of testing radiated spurious 9 kHz to 30 MHz
Setup
 The equipment is set up to simulate normal operation mode as described in the user manual or defined
by the manufacturer.
 If the EUT is a tabletop system, it is placed on a table with 0.8 m height.
 If the EUT is a floor standing device, it is placed directly on the turn table.
 Auxiliary equipment and cables are positioned to simulate normal operation conditions as described in
ANSI C 63.4.
 The AC power port of the EUT (if available) is connected to a power outlet below the turntable.
 Measurement distance is 3 m (see ANSI C 63.4) – see test details.
 EUT is set into operation.
Premeasurement*
 The turntable rotates from 0° to 315° using 45° steps.
 The antenna height is 1 m.
 At each turntable position the analyzer sweeps with positive-peak detector to find the maximum of all
emissions.
Final measurement
 Identified emissions during the pre-measurement are maximized by the software by rotating the turntable
from 0° to 360°.
 The final measurement is done in the position (turntable and elevation) causing the highest emissions
with quasi-peak (as described in ANSI C 63.4).
 Final levels, frequency, measuring time, bandwidth, turntable position, correction factor, margin to the
limit and limit will be recorded. A plot with the graph of the premeasurement and the limit is stored.
*)Note: The sequence will be repeated three times with different EUT orientations.

ANSI C63.4.
 Based on antenna and turntable positions at which the peak values are measured the software maximize
the peaks by changing turntable position ± 45° and antenna height between 1 and 4 m.
 The final measurement is done with quasi-peak detector (as described in ANSI C 63.4).
 Final levels, frequency, measuring time, bandwidth, antenna height, antenna polarization, turntable angle,
correction factor, margin to the limit and limit are recorded. A plot with the graph of the premeasurement
with marked maximum final results and the limit is stored.

11.9 Spurious emissions radiated below 30 MHz
Description:
Measurement of the radiated spurious emissions in transmit mode below 30 MHz. The EUT is set to single channel
mode and the transmit frequencies are 2402 MHz, 2440 MHz and 2480 MHz. The measurement is performed in
the mode with the highest output power. The limits are recalculated to a measurement distance of 3 m according
the ANSI C63.10.

were detected a re-measurement was performed on the detected frequency with each modulation.

TX spurious emissions radiated
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional
radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB below
that in the 100 kHz bandwidth within the band that contains the highest level of the desired power, based on either an RF
conducted or a radiated measurement. Attenuation below the general limits specified in Section 15.209(a) is not required.
In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the
radiated emission limits specified in §15.209(a) (see §15.205(c)).

The modulation with the highest output power was used to perform the transmitter spurious emissions. If spurious
were detected a re-measurement was performed on the detected frequency with each modulation.

TX spurious emissions radiated
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional
radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB below
that in the 100 kHz bandwidth within the band that contains the highest level of the desired power, based on either an RF
conducted or a radiated measurement. Attenuation below the general limits specified in Section 15.209(a) is not required.
In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the
radiated emission limits specified in §15.209(a) (see §15.205(c)).
