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.

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 is polarized vertical and horizontal.
 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.

Test report no.: 1-6030/18-01-10

7.5 Sequence of testing radiated spurious above 50/85 GHz with external mixers
Setup
 The equipment is set up to simulate normal operation mode as described in the user manual or defined
by the manufacturer.
 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.
 The measurement distance is as appropriate for far field (e.g. 0.25 m).
 The EUT is set into operation.

Premeasurement
 The test antenna with external mixer is handheld and moved carefully over the EUT to cover the EUT’s
whole sphere and different polarizations of the antenna.
 Caution is taken to reduce the possible overloading of the external mixer.

Final measurement
 The final measurement is performed at the position and antenna orientation causing the highest emissions
with Peak and RMS detector (as described in ANSI C 63.4).
 As external mixers may generate false images care is taken to ensure that any emission measured by
the spectrum analyzer does indeed originate in the EUT. Signal identification feature of spectrum analyzer
is used to eliminate false mixer images (i.e., it is not the fundamental emission or a harmonic falling
precisely at the measured frequency).
 Final levels, frequency, measuring time, bandwidth, correction factor, margin to the limit and limit are
recorded. A plot with the graph of the premeasurement and the limit is stored.
