NOTE: "not tested" parameters on applicants request. The ARS 2-C is a variant of the ARS 2-A as
full tested according to test report EMCC-980162IAA, 2003-FEB-06.

The client has made the determination that EUT Condition, Characterization, and Mode of Operation are
representative of production units, and meet the requirements of the specifications referenced herein.

Consistent with Industry practice, measurement and test equipment not directly involved in obtaining
measurement results but having an impact on measurements (such as cable loss, antenna factors, etc.)
are factored into the "Correction Factor" documented in certain test results. Instrumentation employed
for testing meets tolerances consistent with known Industry Standards and Regulations.

The measurements contained in this report were made in accordance with the procedure ANSI C63.4 -
1992 and IEEE Std C95.3-1991. All requirements were found to be within the limits outlined in this
report.
The test results in this report apply only to the particular Equipment Under Test (EUT) as declared in this
report.

Section 15.35 Measurement detector functions and bandwidths.
(b) On any frequency of frequencies above 1000 MHz, the radiated limits shown are based upon the use
of measurement instrumentation employing an average detector function. When average radiated
emission measurements are specified in the regulations, including emission measurements below 1000
MHz, there is also a limit on the radio frequency emissions, as measured using instrumentation with a
peak detector function, corresponding to 20 dB above the maximum permitted average limit for the
frequency being investigated unless a different peak emission limit is otherwise specified in the rules in
this part, e.g., see § 15.255. Unless otherwise specified, measurements above 1000 MHz shall be
performed using a minimum resolution bandwidth of 1 MHz. Measurement of AC power line conducted
emissions are performed using a CISPR quasipeak detector, even for devices for which average
radiated emission measurements are specified.

Section 15.209 (a) Except as provided elsewhere in this subpart, the emissions from an intentional
radiator shall not exceed the field strength levels specified in the following table:

Frequency                       Field Strength                     Measurement distance

(b) In the emission table above, the tighter limit applies at the band edges.

(c) The level of any unwanted emissions from an intentional radiator operating under these general
provisions shall not exceed the level of the fundamental emission. For intentional radiators which operate
under the provisions of other sections within this part and which are required to reduce their unwanted
emissions to the limits specified in this table, the limits in this table are based on the frequency of the
unwanted emission and not the fundamental frequency. However, the level of any unwanted emissions
shall not exceed the level of the fundamental frequency.

(d) The emission limits shown in the above table are based on measurements employing a CISPR quasi
peak detector except for the frequency bands 9–90 kHz, 110–490 kHz and above 1000 MHz. Radiated
emission limits in these three bands are based on measurements employing an average detector.
(e) The provisions in §§ 15.31, 15.33, and 15.35 for measuring emissions at distances other than the
distances specified in the above table, determining the frequency range over which radiated emissions
are to be measured, and limiting peak emissions apply to all devices operated under this part.

4.2.2 Test Procedures
For tabletop equipment, the EUT is placed on a 1 meter by 1.5 meters wide and 0.8 meter high
nonconductive table that sits on a flush mounted metal turntable. Floor standing equipment is placed
directly on the flush mounted metal turntable. The EUT is connected to its associated peripherals with
any excess I/O cabling bundled to approximately 1 meter.
The EUT was tested as a tabletop equipment, connected with peripherals as described in chapter 2.2.
The tests were performed in one mode as described in chapter 2.3.
The initial step in collecting radiated data is a peak scan of the measurement range with an EMI test
receiver under closer distances as given in the rule. The significant peaks are then measured with the
appropriate distance and detectors.
Worst case radiated emissions are listed under chapter: test results.




2
    The end frequency 26.5 GHz of this chapter was selected because of the end frequency of the coaxial RF input of the
     spectrum analyzer used as test receiver.

4.2.4 Average Correction Factor
NOTE: All AV measurements were performed using the test receiver’s average detector and the max.
hold facility; the average value measured directly without the necessity of additional correction factor.



4.2.5 Field Strength Calculation
The field strength is calculated by adding the Antenna Factor and Cable Factor. The basic equation with
a sample calculation is as follows:

FS = RA + AF + CF
where
    FS = Field Strength in dBµV/m
    RA = Receiver Amplitude in dBµV
    AF = Antenna Factor in dB(1/m)
    CF = Cable Attenuation Factor in dB

Assume a receiver reading of 23.5 dBµV is obtained. The Antenna Factor of 7.4 dB(1/m) and a Cable
Factor of 1.1 dB are added, giving a field strength of 32 dBµV/m. The 32 dBµV/m value can be
mathematically converted to its corresponding level in µV/m.

FS = 23.5 + 7.4 + 1.1 = 32 [dBµV/m]

Level in µV/m = Common Antilogarithm (32/20) = 39.8

4.3.2 Test Procedures
The basic test setups and procedures are the same as for the tests 30 MHz to 26.5 GHz. Above 26.5
GHz additional external mixers have to be used, which results in additional correction factors.
Due to high mixer loss at very high frequencies the distance between the EUT and the test antenna was
reduced to very low values (some cm) to detect any emissions.
The operating band 76 GHz to 77 GHz was excluded.

field except where it can be shown that near field measurements are appropriate due to the
characteristics of the device; and it can be demonstrated that the signal levels needed to be measured at
the distance employed can be detected by the measurement equipment. (...) When performing
measurements at a distance other than that specified, the results shall be extrapolated to the specified
distance using an extrapolation factor of 20 dB/decade (inverse linear-distance for field strength
measurements; inverse-linear-distance-squared for power density measurements).

4.3.4 Field Strength Calculation
The field strength is calculated by adding the Antenna Factor and Mixer Loss. The basic equation with a
sample calculation is as follows:

FS = RA + AF + ML
where
    FS = Field Strength in dBµV/m
    RA = Receiver Amplitude in dBµV
    AF = Antenna Factor in dB(1/m)
    ML = Mixer Loss in dB

Assume a receiver reading of 10.2 dBµV is obtained. The Antenna Factor of 38.8 dB(1/m) and a Mixer
Loss of 22 dB are added, giving a field strength of 71 dBµV/m. The 71 dBµV/m value can be
mathematically converted to its corresponding level in µV/m.

FS = 10.2 + 38.8 + 22 = 71 [dBµV/m]

Level in µV/m = Common Antilogarithm (71/20) = 3,548


For test distance other than what is specified, but fulfilling the requirements of Section 15.31 (f)(1) the
field strength is calculated by adding additionally an extrapolation factor of 20 dB/decade (inverse linear-
distance for field strength measurements). The basic equation with a sample calculation is as follows:

FS = RA + AF + ML + DF
where
    FS = Field Strength in dBµV/m
    RA = Receiver Amplitude in dBµV
    AF = Antenna Factor in dB(1/m)
    ML = Mixer Loss in dB
    DF = Distance Extrapolation Factor in dB,
      where DF = 20 log (Dtest/Dspec) where Dtest = Test Distance and Dspec = Specified Distance.

Assume the tests performed at a reduced Test Distance of 1 m instead of the Specified Distance
of 3 m giving a Distance Extrapolation Factor of DF = 20 log(1m/3m) = -9.5 dB.
Assuming a receiver reading of 10.2 dBµV is obtained. The Antenna Factor of 38.3 dB(1/m), the Mixer
Loss of 22 dB and the Distance Factor of -9.5 dB are added, giving a field strength of 61.5 dBµV/m. The
61.5 dBµV/m value can be mathematically converted to its corresponding level in µV/m.

FS = 10.2 + 38.8 + 22 - 9.5 = 61.5 [dBµV/m]

Level in µV/m = Common Antilogarithm (61.5/20) = 1,188

4.3.5 Power Density Calculation
The power density is calculated by using the reading, mixer loss, effective aperture of the antenna and
distance correction factor (20 dB/dec relation).
The basic calculation is similar as described in the chapter above with the difference, that the result is
the power density:

PD = RA + ML + DF - A
where
   PD = Power Density in dBm/cm²,
   RA = Receiver Amplitude in dBm,
   ML = Mixer Loss in dB,
   DF = Distance Extrapolation Factor in dB,
   A = effective Antenna Aperture in dB(cm²)
      where DF = 20 log (Dtest/Dspec) where Dtest = Test Distance and Dspec = Specified Distance,
      and A = 10 log (effective Antenna Aperture in cm²).

For an assumed result of -60 dBm/cm² the level in pW/cm² is:
109 x Common Antilogarithm (-60/10) = 1,000
