6 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).

7 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°.
• Loop antenna is rotated about its vertical axis for maximum response at each azimuth about the EUT.
(For certain applications, the loop antenna plane may also need to be positioned horizontally at the
specified distance from the EUT)
• 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.

7.2 Sequence of testing radiated spurious 30 MHz to 1 GHz
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, a table with 0.8 m height is used, which is placed on the ground plane.
• If the EUT is a floor standing device, it is placed on the ground plane with insulation between both.
• 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 10 m or 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 is polarized vertical and horizontal.
• The antenna height changes from 1 m to 3 m.
• At each turntable position, antenna polarization and height the analyzer sweeps three times in peak to
find the maximum of all emissions.

Final measurement
• The final measurement is performed for at least six highest peaks according to the requirements of the
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.

• The antenna height is 1.5 m.
• At each turntable position and antenna polarization the analyzer sweeps with positive peak detector to
find the maximum of all emissions.

Final measurement
• The final measurement is performed for at least six highest peaks according to the requirements of the
ANSI C63.4.
• Based on antenna and turntable positions at which the peak values are measured the software maximizes
the peaks by rotating the turntable from 0° to 360°. This measurement is repeated for different EUT-table
positions (0° to 150° in 30°-steps) and for both antenna polarizations.
• The final measurement is done in the position (turntable, EUT-table and antenna polarization) causing
the highest emissions with Peak and RMS detector (as described in ANSI C 63.4).
• Final levels, frequency, measuring time, bandwidth, turntable position, EUT-table position, antenna
polarization, 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.

(c) Unless otherwise specified, e.g. Section 15.255(b), when the radiated emission limits are expressed in
terms of the average value of the emission, and pulsed operation is employed, the measurement field strength
shall be determined by averaging over one complete pulse train, including blanking intervals, as long as the

0.1 seconds) or in cases where the pulse train exceeds 0.1 seconds, the measured field strength shall be
determined from the average absolute voltage during a 0.1 second interval during which the field strength is
at its maximum value. The exact method of calculating the average field strength shall be submitted with any
application for certification or shall be retained in the measurement data file for equipment subject to
notification or verification.
