Measurements Required: Conducted Spurious and Harmonic Emissions at Antenna Terminals Analog Mode
Graph Attached
EXHIBIT NO. 6G-1, 6G-2
Definition - (as used herein) Spurious radiations are the radio frequency voltages or power generated
within the equipment and appearing at the equipment's output terminals when properly loaded with its
characteristic non-radiating artificial load.
Minimum Standard - Conducted spurious and harmonic emissions shall be attenuated 43 dB 10Log10(the mean power output). In the frequencies from 869 MHz to 894 MHz and from 1930 MHz
to 1990 MHz, no spur shall exceed -80dBm.
Method of Measurement -The Antenna port of the sample was directly coupled to the input of the
EMI receiver through a special coupling cable and a 10 dB passive attenuator. Scans were then
performed from 30 MHz to 6.5 GHz, while observing the fundamental signal level, plus low order
harmonics or other spurious signals. The frequency range of 1 to 6.5GHz was then inspected, and
the level of the harmonics was measured and recorded. The output of the sample was then switched
to a Hewlett Packard HP8563E spectrum analyzer to verify harmonic signal levels out to the tenth
harmonic. The bandwidth was initially set to 1 MHz for signature scans, and then reduced to 30 kHz
to measure individual signal strengths.

Definition - Radiated spurious and harmonic emissions from the equipment when loaded into a nonradiating load at a frequency or frequencies which are outside an occupied band sufficient to insure
transmission of information of required quality for the class of communications desired. The
reduction in the level of these spurious emissions will not effect the quality of information being

10Log10(the mean power output). In the frequencies from 869 MHz to 894 MHz and from 1930 MHz
to 1990 MHz, no spur shall exceed -80dBm.
Method of Measurement:
Test Site - The test sample was operated within the 3 meter Open Area Test Site, FCC listed
chamber located at Fluke Park II, Everett, WA.
Installation of Equipment – The sample was placed on an 80cm high small wooden pedestal, which
was centered on the flush-mounted 2m diameter metal turntable. The test sample was operated on
its internal rechargeable battery. The test sample was configured to run in a continuous transmit
mode during the Radiated measurements. The test sample was set to operate on standard channels
within the Cellular frequency assignment: one at the low end of the band (991), one in the middle of
the band (385) and one near the top of the band (799). The test sample was set to operate on
standard channels within the PCS frequency assignment: one at the low end of the band (2), one in
the middle of the band (1000) and one near the top of the band (1998).
All equipment is calibrated and used according to the user manuals supplied by the manufacturer.
All antenna calibrations were performed at a N.I.S.T traceable site, and the resultant correction
factors were used. When a reading is taken using the peak detector, a duty cycle correction factor
can be applied for conversion to an average reading. This operation can be used when measuring
periodic data transmission, under FCC part 15.231b, and Part 15.35c. The resulting average reading
was then compared to the appropriate limit in order to determine compliance. The HP 8562A EMI
receiver was operated with a bandwidth of 100kHz when receiving signals below 1GHz, and with a
bandwidth of 1MHz when receiving signals above 1GHz, in accordance with CISPR 16. While
performing the Part 15 measurements. Other IF and Video bandwidths, narrower than stated above,
were used where appropriate and allowable.
Measurement Procedure – The fundamental and spurious (harmonic) emissions of the transmitter
were tested for compliance to Title 47 CFR, FCC Part 22.917e limits for transmitters in the Public
mobile services, and were also compared with the general limits laid out in Part 15.109. The samples
were tested from the lowest frequency generated by the transmitter (without going below 9 kHz) to
the 10th harmonic of the fundamental frequency generated by the device. The limits described in
part 15.109 were also observed for observation and measurement of spurious signals. The samples
were placed on a nonconductive (wooden) pedestal at the OATS facility and the antenna mast was
placed such that the antenna was 3m from the test object. A biconical antenna was used to measure
emissions from 30 to 200 MHz, a log periodic was used to measure emissions from 200 to 1000
MHz. A dual ridged waveguide horn with HP preamplifier was used to measure emissions from 1
GHz to 20 GHz. The test object was programmed to operate in continuous transmit, either in the
analog mode or digital mode; and the resultant signals were maximized by rotating the turntable 360
degrees, and by raising and lowering the antenna between 1 and 4 meters using both horizontal and
vertical antenna polarities.

Measurement Required: Frequency Stability - Analog & Digital Modes
Graph Attached
EXHIBIT NO. 6J1 & 6J2
Definition - The carrier frequency stability is the ability of the transmitter to maintain an assigned
carrier frequency.
Minimum Standard - The minimum frequency stability shall be +/-0.00025% at any time during
normal operation.
Method of Measurement - Frequency measurements shall be made at the extremes of the
temperature range -30° to +60° and at intervals of not more than 10° C throughout the range. A
period of time sufficient to stabilize all of the components in the equipment shall be allowed prior to
each frequency measurement. In the analog mode, the frequency of the transmitter shall be
measured by extracting a sample of the carrier and measuring its center frequency by equipment
having a degree of accuracy of at least 10 times that of the minimum to be measured. In the digital
mode, a received signal shall be supplied to the transceiver and the transmitter carrier frequency
offset shall be measured with respect to the received signal frequency. The frequency stability of
transmitting equipment shall be checked with variations in:
(a) Temperature:
Vary the ambient temperature from -30 C to +60 C.

(b) Primary Supply Voltage:
Vary the primary supply voltage over the operational input voltage range normally
measured at the input to the power cable supplied or at the power supply terminals if
cables are not normally supplied.
TIMING PERIOD AND PROCEDURE
1. The carrier frequency of the transmitter and the individual oscillators were measured at room
temperature (usually between 25° and 27° C) to provide a reference.
2. The equipment was then subjected to an overnight "soak" at -30° C without any power applied.
3. After an overnight "soak" at -30° C (usually 14 to 16 hours) the equipment was turned on in a
"standby" condition for one minute before applying power to the transmitter. Measurement of the
carrier frequency of the transmitter and the individual oscillators was made within a three minute
interval after applying power to the transmitter.
4. Frequency measurements were made at each 10° C interval up to room temperature (-30°, -20°, 10°, 0°, +10°, +20°). At least a period of one and one half hours was provided to allow stabilization of
the equipment at each temperature level.
5. Again the transmitter carrier frequency and the individual oscillators were measured at room
temperature to begin measurement of the upper temperature extreme.
6. Frequency measurements were made at 10° intervals starting at +30° C and ending at +60° C
allowing at least two hours at each temperature for stabilization. In all measurements the frequency
was measured within three minutes after applying power to the transmitter.
7. In all measurements, at the various temperature intervals, the temperature was held to +1° C from
the temperature level and the equipment turned on for one minute standby condition before applying
transmitter power.
8.The artificial load was mounted external to the temperature chamber.
