2. RF Power Output

Date of Test: October 10, 2002
Temperature: 60° F
Relative Humidity: 65


2.1 Test Requirement

Section 2.1046 Measurements required: RF power output.

(a) For transmitters other than single sideband, independent sideband and controlled carrier radiotelephone, power output
shall be measured at the RF output terminals when the transmitter is adjusted in accordance with the tune-up procedure to
give the values of current and voltage on the circuit elements specified in § 2.1033(c)(8). The electrical characteristics of
the radio frequency load attached to the output terminals when this test is made shall be stated.


2.2 Test Technical Standard

Section 101.113 Transmitter power limitations.

(a) On any authorized frequency, the average power delivered to an antenna in this service must be the minimum amount
of power necessary to carry out the communications desired. Application of this principle includes, but is not to be
limited to, requiring a licensee who replaces one or more of its antennas with larger antennas to reduce its antenna input
power by an amount appropriate to compensate for the increased primary lobe gain of the replacement antenna(s). In no
event shall the average equivalent isotropically radiated power (EIRP), as referenced to an isotropic radiator, exceed the
values specified below. In cases of harmful interference, the Commission may, after notice and opportunity for hearing,
order a change in the effective radiated power of this station. Further, the output power of a transmitter on any authorized
frequency in this service may not exceed the following:


                  Frequency Band                         Maximum Allowable EIRP 1, 2
                      (MHz)                       Fixed (dBW)               Mobile (dBW)

3. Occupied Bandwidth

Date of Test: October 10, 2002
Temperature: 60
Relative Humidity: 65



3.1 Test Requirement

Section 2.1049 Measurements required: Occupied bandwidth

The occupied bandwidth, that is the frequency bandwidth such that, below its lower and above its upper frequency limits,
the mean powers radiated are each equal to 0.5 percent of the total mean power radiated by a given emission shall be
measured under the following conditions as applicable:

(h) Transmitters employing digital modulation techniques—when modulated by an input signal such that its amplitude
and symbol rate represent the maximum rated conditions under which the equipment will be operated. The signal shall be
applied through any filter networks, pseudo-random generators or other devices required in normal service. Additionally,
the occupied bandwidth shall be shown for operation with any devices used for modifying the spectrum when such
devices are optional at the discretion of the user.


3.2 Test Technical Standard

Section 101.111 Emission limitations

(a) The mean power of emissions must be attenuated below the mean power output of the transmitter in accordance with
the following schedule:

(5) When using transmissions employing digital modulation techniques on the 900 MHz multiple address frequencies with
a 12.5 kHz bandwidth, the power of any emission must be attenuated below the unmodulated carrier power of the
transmitter (P) in accordance with the following schedule:

(i) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of
more than 2.5 kHz up to and including 6.25 kHz: At least 53 log (fd/2.5) decibels;

(ii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of
more than 6.25 kHz up to and including 9.5 kHz: At least 103 log (fd/3.9) decibels;

(iii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of
more than 9.5 kHz up to and including 15 kHz: At least 157 log (fd/5.3) decibels; and

(iv) On any frequency removed from the center of the authorized bandwidth by a displacement frequency greater than 15
kHz: At least 50 plus 10 log (P) or 70 decibels, whichever is the lesser attenuation.

4. Measurement of Necessary Bandwidth

Date of Test: October 10, 2002
Temperature: 60
Relative Humidity: 65


4.1 Test Requirement

Section 2.202
(C) The necessary bandwidth may be determined by one of the following methods:

(4) Measurement in cases not covered by paragraph (C) (1), (2), or (3) of this section.

It is not possible to calculate necessary bandwidth in accordance with 47CFR Part 2 Section 2.202 (c) (1), (2), or (3).
Therefore, per Section 2.202 (c) (4) the actual 99 percent bandwidth was required to be measured.


4.2 Test Technical Standards

Section 101.109 Bandwidth

(a) Each authorization issued pursuant to these rules will show, as the emission designator, a symbol representing the class
of emission which must be prefixed by a number specifying the necessary bandwidth. This figure does not necessarily
indicate the bandwidth actually occupied by the emission at any instant. In those cases where part 2 of this chapter does
not provide a formula for the computation of the necessary bandwidth, the occupied bandwidth may be used in the
emission designator.

(b) Stations in this service will be authorized any type of emission, method of modulation, and transmission characteristic,
consistent with efficient use of the spectrum and good engineering practice, except that Type B, damped-wave emission
will not be authorized.

(c) The maximum bandwidth which will be authorized per frequency assigned is set out in the table that follows.
Regardless of the maximum authorized bandwidth specified for each frequency band, the Commission reserves the right
to issue a license for less than the maximum bandwidth if it appears that a lesser bandwidth would be sufficient to support
an applicant's intended communications.

                        Frequency Band (MHz)                  Maximum authorized bandwidth
                              952 to 960                             200 kHz 1, 5, 6


1) The maximum bandwidth that will be authorized for each particular frequency in this band is detailed in the appropriate
frequency table in § 101.147. If contiguous channels are aggregated in the 928-928.85/952-952.85/956.25-956.45 MHz,
the 928.85-929/959.85-960 MHz, or the 932-932.5/941-941.5 MHz bands, then the bandwidth may exceed that which is
listed in the table.
5) A 12.5 kHz bandwidth applies only to frequencies listed in § 101.147 (b) (1) through (4).
6) For frequencies listed in Section 10 1. 147 (b) (1) through (4), consideration will be given on a case-by-case basis to
authorizing bandwidths up to 50 kHz.

Date of Test: October 10, 2002
Temperature: 60
Relative Humidity: 65


5.1 Test Requirement

Section 2.1051 Measurements required: Spurious emissions at antenna terminals

The radio frequency voltage or powers generated within the equipment and appearing on a spurious frequency shall be
checked at the equipment output terminals when properly loaded with a suitable artificial antenna. Curves or equivalent
data shall show the magnitude of each harmonic and other spurious emission that can be detected when the equipment is
operated under the conditions specified in § 2.1049 as appropriate. The magnitude of spurious emissions which are
attenuated more than 20 dB below the permissible value need not be specified.


5.2 Test Technical Standard

Section 101.111 Emission limitations

(a) The mean power of emissions must be attenuated below the mean power output f the transmitter in accordance with
the following schedule:

(5) When using transmissions employing digital modulation techniques on the 900 MHz multiple address frequencies with
a 12.5 kHz bandwidth, the power of any emission must be attenuated below the unmodulated carrier power of the
transmitter (P) in accordance with the following schedule:

(iv) On any frequency removed from the center of the authorized bandwidth by a displacement frequency greater than 15
kHz: At least 50 plus 10 log (P) or 70 decibels, whichever is the lesser attenuation.

6. Field Strength of Spurious Radiation

Date of Test: October 11, 12, & 14, 2002
Temperature: 57
Relative Humidity: 71


6.1 Test Requirement

Section 2.1053 Measurements required: Field strength of spurious radiation

(a) Measurements shall be made to detect spurious emissions that may be radiated directly from the cabinet, control
circuits, power leads, or intermediate circuit elements under normal conditions of installation and operation. Curves or
equivalent data shall be supplied showing the magnitude of each harmonic and other spurious emission. For this test,
single sideband, independent sideband, and controlled carrier transmitters shall be modulated under the conditions
specified in paragraph (c) of § 2.1049, as appropriate. For equipment operating on frequencies below 890 MHz, an open
field test is normally required, with the measuring instrument antenna located in the far-field at all test frequencies. In the
event it is either impractical or impossible to make open field measurements (e.g. a broadcast transmitter installed in a
building) measurements will be accepted of the equipment as installed. Such measurements must be accompanied by a
description of the site where the measurements were made showing the location of any possible source of reflections
which might distort the field strength measurements. Information submitted shall include the relative radiated power of
each spurious emission with reference to the rated power output of the transmitter, assuming all emissions are radiated
from halfwave dipole antennas.

(b) The measurements specified in paragraph (a) of this section shall be made for the following equipment:

(1) Those in which the spurious emissions are required to be 60 dB or more below the mean power of the transmitter.
(2) All equipment operating on frequencies higher than 25 MHz.
(3) All equipment where the antenna is an integral part of, and attached directly to the transmitter.
(4) Other types of equipment as required, when deemed necessary by the Commission.


6.2 Test Technical Standard

Section 101.111 Emission limitations

(a) The mean power of emissions must be attenuated below the mean power output f the transmitter in accordance with
the following schedule:

(5) When using transmissions employing digital modulation techniques on the 900 MHz multiple address frequencies with
a 12.5 kHz bandwidth, the power of any emission must be attenuated below the unmodulated carrier power of the
transmitter (P) in accordance with the following schedule:

(iv) On any frequency removed from the center of the authorized bandwidth by a displacement frequency greater than 15
kHz: At least 50 plus 10 log (P) or 70 decibels, whichever is the lesser attenuation.

6.3 Test Procedure

TIA/EIA-603:1993 Section 2.2.12




                                                              13


                                                                                                                FCC ID: EO9-MC


RADIATED POWER LIMIT

All emissions are expressed in terms of the equivalent power that would be radiated by a substitution antenna, positioned
where the center of the device under test was located, in order to produce the same electric field strength as radiated by the
device under test. This level is equivalent to the power applied to the input of the substitute antenna plus the gain (dBi) of
the antenna

The output power of the transmitter is +38.91 dBm (+8.91 dBW) or 7.78 Watts.

Therefore the minimum attenuation allowed is 50 + 10 Log 7.78 = 58.91 dBW.
Therefore the maximum absolute power of the spurious emission is +8.91 dBW – 58.91 dBW or –50 dBW or –20 dBm.

7.1 Test Requirement

Section 2.1055 Measurements required: Frequency stability.

(a) The frequency stability shall be measured with variation of ambient temperature as follows:
    (1) From -30 degrees to +50 degrees centigrade for all equipment except that specified in paragraphs (a) (2) and (3) of
    this section.

(b) Frequency measurements shall be made at the extremes of the specified temperature range and at intervals of not more
than 10° centigrade through the range. A period of time sufficient to stabilize all of the components of the oscillator
circuit at each temperature level shall be allowed prior to frequency measurement. The short term transient effects on the
frequency of the transmitter due to keying (except for broadcast transmitters) and any heating element cycling normally
occurring at each ambient temperature level also shall be shown. Only the portion or portions of the transmitter
containing the frequency determining and stabilizing circuitry need be subjected to the temperature variation test.

(d) The frequency stability shall be measured with variation of primary supply voltage as follows:

    (1) Vary primary supply voltage from 85 to 115 percent of the nominal value for other than hand carried battery
    equipment.

    (2) For hand carried, battery powered equipment, reduce primary supply voltage to the battery operating end point
    which shall be specified by the manufacturer.

    (3) The supply voltage shall be measured at the input to the cable normally provided with the equipment, or at the
    power supply terminals if cables are not normally provided. Effects on frequency of transmitter keying (except for
    broadcast transmitters) and any heating element cycling at the nominal supply voltage and at each extreme also shall
    be shown.

7.2 Test Technical Standard

Section 101.107 Frequency tolerance.

(a) The carrier frequency of each transmitter authorized in these services must be maintained within the percentage of the
reference frequency except as otherwise provided in paragraph (b) of this section or in the applicable subpart of this part
(unless otherwise specified in the instrument of station authorization the reference frequency will be deemed to be the
assigned frequency):
…
952 to 960 (7) ……… ……… ………
…
(7) For private operational fixed point-to-point microwave systems, with a channel greater than or equal to 50 KHz
bandwidth, ±0.0005%; for multiple address master stations, regardless of bandwidth, ±0.00015%; for multiple address
remote stations with 12.5 KHz bandwidths or less, ±0.00015%; for multiple address remote stations with channels greater
than 12.5 KHz bandwidth, ±0.0005%.

Limit = ±0.00015% * 954,499,989 Hz = ±1431.7 Hz.

8. Radio-Frequency Exposure

Date of Test: October 10, 2002
Temperature:
Relative Humidity:


8.1 RF Exposure
Section 1.1310 Radiofrequency radiation exposure limits.

Table 1 (B). See also § 1. 1307(b)(1) of the FCC Rules.


8.2 Classification

According to Section 1.1307b(l), the EUT does not require an environmental evaluation.

          1.   This equipment classification is not listed within Table 1 of Section 1.1307 and is not
               listed in Section 1.1307b(2).

          2.   The EUT is a fixed transmitter and is thus categorically exempt from routine environmental evaluation
               per Section 2.1093.

Included in the following section of this Test Report are calculations that determine that minimum distance from the
transmitter antenna that will ensure an exposure limit at or below the guidelines given in Table I of Section 1.1310 for the
general population. The formula for these calculations are taken from OET Bulletin' 65, edition 97-01, August 1997;
"Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields".

8.3 Calculations

The EUT is intended to be used in a mobile environment.

Per Table 1 of Section 1.1310, the Maximum Permissible Exposure (MPE) limit for General Population/Uncontrolled
Exposure in the band of 300-1500 MHz is equal to f/1500 = 956/1500 or 0.638 mW/cm2.

Supplement C, Edition 01-01, of OET Bulletin 65, Edition 97 - 01,

The formula for calculating power density is:
Pd = Pt * G / 4 PI * r2

Power = +35.91 dBm = 3.90 W
Gain of the mobile antenna = 5 dBi or a numeric gain of 3.16.
Therefore solving for r gives a minimum safe distance of 39.2 cm.

The FCC specified maximum safe distance for mobile installations is 2 meters.

8.4 Conclusion
The EUT complies with the requirements of Table (B) limits for Maximum Permissible Exposure (MPE) for the general
population uncontrolled exposure of Section 1.1310 of the FCC Regulations. The manufacturer has specified 40 cm as
the minimum safe distance in the User Manual.
