                                    Description of Tests

                                       Conducted Emissions

                                     The line-conducted facility is located inside a 16'x20'x10' shielded
                                     enclosure. It is manufactured by Ray Proof Series 81 (see Figure 2).
     Figure 2. Shielded Enclosure
     Line-Conducted Test Facility    The shielding effectiveness of the shielded room is in accordance with
                                     MIL-Std-285 or NSA 65-6. A 1m. x 1.5m. wooden table 80cm. high is
                                     placed 40cm. away from the vertical wall and 1.5m away from the
                                     side wall of the shielded room (see Figure 3). Solar Electronics and
                                     EMCO Model 3725/2 (10kHz-30MHz) 50Ω/50µH Line-Impedance
                                     Stabilization Networks (LISNs) are bonded to the shielded room (see
                                     Figure 4). The EUT is powered from the Solar LISN and the support
                                     equipment is powered from the EMCO LISN. Power to the LISNs are
                                     filtered by a high-current high-insertion loss Ray Proof power line
                                     filters (100dB 14kHz-10GHz). The purpose of the filter is to attenuate
                                     ambient signal interference and this filter is also bonded to the
     Figure 3. Line Conducted        shielded enclosure. All electrical cables are shielded by braided
       Emission Test Set-Up          tinned copper zipper tubing with an inner diameter of 1/2". If the EUT
                                     is a DC-powered device, power will be derived from the source power
                                     supply it normally will be powered from, and the supply lines will be
                                     connected to the Solar LISN. LISN schematic diagram is shown in
                                    Figure 5. All interconnecting cables more than 1 meter were shortened
                                    by non-inductive bundling (serpentine fashion) to a 1-meter length.
                                    Sufficient time for the EUT, support equipment, and test equipment was
                                    allowed in order for them to warm up to their normal operating
                                    condition. The RF output of the LISN was connected to the spectrum
    Figure 4. Wooden Table &        analyzer to determine the frequency producing the maximum EME
          Bonded LISNs              from the EUT. The spectrum was scanned from 450kHz to 30MHz
                                    with 20 msec. sweep time. The frequency producing the maximum
                                    level was reexamined using EMI/ Field Intensity Meter and Quasi-Peak
                                    adapter. The detector function was set to CISPR quasi-peak mode.
                                    The bandwidth of the receiver was set to 10 kHz. 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/or support equipment, and powering the monitor from the
                                    floor mounted outlet box and the computer aux AC outlet, if
                                    applicable; whichever determined the worst-case emission.
                                    Photographs of the worst-case emission can be seen in Attachment H.
                                    Each EME reported was calibrated using the HP8640B signal generator.

                               Preliminary measurements were made indoors at 1 meter using
                               broadband 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 were noted for each frequency found. The spectrum was
 Figure 6. 3-Meter Test Site   scanned from 30 to 200 MHz using biconical antenna and from 200 to
                               1000 MHz using log-spiral antenna. Above 1 GHz, linearly polarized
                               double ridge horn antennas were used.
                               Final measurements were made outdoors at 3-meter test range using
                               Roberts Dipole antennas or horn antenna (see Figure 6). The test
                               equipment was placed on a wooden and plastic bench situated on a 1.5 x
                               2 meter area adjacent to the measurement area (see Figure 7). 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 re-examined and
                               investigated using EMI/Field Intensity Meter and Quasi-Peak Adapter. The
  Figure 7. Dimensions of      detector function was set to CISPR quasi-peak mode and the bandwidth of
     Outdoor Test Site         the receiver was set to 100kHz or 1 MHz 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 set-up producing the
                               maximum emission for the frequency and were placed on top of a 0.8-
                               meter high non-metallic 1 x 1.5 meter table (see Figure 8). The EUT,
                               support equipment, and interconnecting cables were re-arranged and
                               manipulated to maximize each EME emission. The turntable containing
                               the system was rotated; the antenna height was varied 1 to 4 meters and
                               stopped at the azimuth or height producing the maximum emission. Each
  Figure 8. Turntable and
                               emission was maximized by: varying the mode of operation or resolution;
       System Setup            clock or data exchange speed; scrolling H pattern to the EUT and/or
                               support equipment; powering the monitor from the floor mounted outlet
                               box and the computer aux AC outlet if applicable, and changing the
                               polarity of the antenna; whichever determined the worst-case emission.
                               Photographs of the worst-case emission can be seen in Attachment H.
                               Each EME reported was calibrated using the HP8640B signal generator.

        Output Signal Level Measurements
The RF output of the TV interface device was fed to the TV receiver via coaxial cable. The signal level was
measured by direct connection to the spectrum analyzer with 50/75 ohm matching transformer between the
spectrum analyzer and the TV interface device. The RF output signal level measured RMS voltage was the highest
RF level present at the output terminals during normal use of the device. Measurements were made of the levels
of both the visual (61.25 MHz) and aural (71.75 MHz) of TV channel 4. The voltage corresponding to the peak
envelope power of the video modulated signal during maximum amplitude peaks across a resistance (R ohms)
matching the rated output impedance of the device, must not exceed 692.8 R1/2 uV for all other TV interface
device. The voltage corresponding to peak envelope power of the audio modulated signal, if provided by the TV
interface device, must not exceed 155R1/2 uV for cable system terminal device of TV interface device used with a
master antenna, and 77.5 R1/2 uV for all other TV interface device.



        Output Terminal Conducted Spurious Emission
The RF output signal was fed to the TV receiver via coaxial cable. Measurements were made by direct
connection to the spectrum analyzer and TV interface device with 50/75 ohm matching transformer. The
frequency range 30 to 1000 MHz was investigated for significant emission.

The maximum RMS voltage of any emission appearing on frequencies removed by more than 4.6 MHz below or
7.4 MHz above the video carrier frequency on which the TV interface device is operated must not exceed 692.8
R1/2 uV for cable system terminal device or TV interface device used with a master antenna and 1.95 R1/2 uV for all
other TV interface device when terminated with a resistance (R ohms) matching the rated output impedance of the
TV interface device.



        Transfer Switch Isolation Measurement
Measurements were made of the maximum RMS voltage at the antenna input terminals of the switch for all
positions of the transfer switch. The maximum voltage corresponds to the peak envelope power of the video
signal during maximum amplitude peaks. In either position of the receiver transfer switch, the maximum voltage
at the receiving antenna input terminals of the switch when terminated with a resistance (R ohms) matching the
rated impedance of the antenna input of the switch, must not exceed 0.346 R1/2 uV. The maximum voltage
corresponds to the peak envelope power of the video modulated signal during maximum amplitude. Each EME
reported was calibrated using HP8640B signal generator and is listed on Table 4.
