DESCRIPTION OF TESTS
Conducted Emissions
The Line conducted emission test facility is located inside a 4 X 7 X 2.5 meter shielded
enclosure.
It is manufactured by EM engineering. The shielding effectiveness of the shielded room is in
accordance with MIL-STD-285 or NSA 65-6.
A 1mX 1.5M wooden table 0.8m height is placed 0.4m away from the vertical wall and 1.5m away
from the side of wall of the shielded room
Rohde & Schwarz (ESH3-Z5) and Kyoritsu (KNW-408) of the 50ohm/50uH Line Impedance
Stabilization Network(LISN) are bonded to the shielded room.
The EUT is powered from the Rohde & Schwarz LISN and the support equipment is powered
from the Kyoritsu LISN. Power to the LISN s are filtered by high-current high insertion loss power
line filters. The purpose of filter is to attenuate ambient signal interference and this filter is also
bonded to shielded enclosure. All electrical cables are shielded by tinned copper zipper tubing
with inner diameter of 1/2”.
If DC power device, power will be derived from the source power supply it normally will be
powered from and this supply lines will be connected to the LISNs,
All interconnecting cables more than 1 meter were shortened by non inductive bundling
(serpentine fashion) to a 1 meter length.
Sufficient time for EUT, support equipment, and test equipment was allowed in order for them to
warm up to their normal operating condition. The RF out put of the LISN was connected to the
spectrum analyzer to determine the frequency producing the maximum EME from the EUT.
The spectrum was scanned from450KHz to 30MHz with 20msec sweep time.
The frequency producing the maximum level was re-examined using the EMI test
receiver .(Rohde & Schwarz ESCS30).
The detector function was set to CISPR quasi-peak mode.
The bandwidth of receiver was set to 9KHz. The EUT, support equipment, and interconnecting
cables were arranged and manipulated to maximize each EME emission.
Each emission was maximized by; switching power lines; varying the mode of operation or
resolution; clock or data exchange speed; scrolling H pattern to the EUT and of support
equipment, and powering the monitor from the floor mounted outletbox and computer aux AC
outlet, if applicable; which ever determined the worst case emission.
Each EME reported was calibrated using the R&S signal generator.

Radiated Emissions
Preliminary measurement were made indoor at 1 meter using broad band antennas, broadband
amplifier, and spectrum analyzer to determine the frequency producing the maximum EME.
Appropriate precaution was taken to ensure that all EME from the EUT were maximized and
investigated. The system configuration, clock speed, mode of operation or video resolution,
turntable azimuth with respect to the antenna was note for each frequency found.
The spectrum was scanned from 30 to 1000MHz using Biconical log Antenna (ARA, LPB-2520/A).
Above 1GHz, Doppels Teg Horn antenna (EMCO, DAA-37121:upto 1~18GHz) was used.
Final Measurements were made outdoors at 3 or 10m test range using Logbicon Super
Antenna (Schwarzbeck, VULB9166) or Doppels Teg Horn antenna.(EMCO, DAA-37121)
The test equipment was placed on a wooden table.
Sufficient time for the EUT, support equipment, and test equipment was allowed in order for them
to warm up to their normal operating condition.
Each frequency found during pre-scan measurements was reexamined and investigated using
EMI test receiver.(ESCS30)
The detector function was set to CISPR quasi-peak mode and the bandwidth of the receiver was
set to 120KHz or 1MHz depending on the frequency or type of signal.
The half wave dipole antenna was tuned to the frequency found during preliminary radiated
measurements.
The EUT support equipment and interconnecting cables were re configured to the setup
producing the maximum emission for the frequency and were placed on top of a 0.8m high non-
metallic 1.0X 1.5-meter table.
The EUT, support equipment and interconnecting cables were re-arranged and manipulated to
maximize each EME emission.
The turn table containing the system was rotated; the antenna height was varied 1 to 4meter and
stopped at the azimuth or height producing the maximum emission Each emission was
maximized by: switching power lines; varying the mode of operation or resolution; clock or data
exchange speed; scrolling H pattern to the EUT and of support equipment, and powering the
monitor from the floor mounted outlet-box and computer aux AC outlet, if applicable; which ever
determined the worst case emission.
