Measurement Procedures Used for Submitted Data
RF Power Output
Pursuant to FCC Rules 2.1046 (a)
Conducted power is measured in accordance with TIA-603-D section 2.2.1.2. The transmitter
under test is connected to an Power Meter using the forward port of a 30 dB attenuator pad and
power sensor. Appropriate calibration offsets, derived from a traceable RF attenuator, which has
been precision characterized by an outside testing laboratory, are entered into the wattmeter to
calibrate for the use of the coupler.
The transmitter is operated under normal conditions at the specified nominal dc input voltage.
The DC voltage applied to the transmitter and the current it draws are read directly from the
calibrated DC Power Supply. Remote voltage sensing is used to ensure the correct DC voltage is
applied to the final PA stage. The DC input power to the final stage (in watts) is computed as the
product of the DC current (in amperes) times the DC voltage (in volts). This measurement is
performed at the lowest, the middle, and the highest operating frequencies of the operating
bandwidth of the equipment.
The calibration of the power meter, detector, and attenuator pads is verified on an annual basis.
Other power measurement systems that may be used are correlated with this calibrated
reference system before measurements are performed, and calibration factors are adjusted as
necessary to obtain precise correlation.
Audio Frequency Response
Pursuant FCC Rules 2.1047 (a)
The transmitter output is monitored with an modulation analyzer, whose FM demodulator output
is fed to an audio analyzer. De-emphasis or filtering within the test equipment is not used. An
audio oscillator signal, derived from the audio analyzer, is connected to the microphone audio
input of the transmitter. At a frequency of 1kHz, the level is adjusted to obtain 20% of full system
deviation, to ensure that limiting does not occur at any frequency in the range of 300Hz
3000Hz. A constant input level is then maintained and the oscillator frequency is varied between
the ranges of 100Hz to 5000Hz. The frequency response is plotted, using a reference of 0 dB at
1kHz.
Audio Low Pass Filter Response
Pursuant FCC Rules 2.1047 (a)
The audio oscillator portion of an audio analyzer is connected to the input of the post limiter low
pass filter. The oscillator is adjusted, at 1000Hz and level 16 dB greater than that required to
produce standard test modulation. The output of the low pass filter is measured with an dynamic
signal analyzer. The response is swept between the limits of 1000Hz - 30000Hz. Oscillator level
is chosen to be as high as possible and that will not cause limiting at any frequency, and
maintaining a constant input level versus frequency.

EXHIBIT 7
SHEET 5 OF 8
Modulation Limiting
Pursuant FCC Rules 2.1047 (b)
An audio oscillator is connected to the microphone audio input. The transmitter output is
monitored with an modulation analyzer. The flat frequency response FM demodulator output of
the modulation analyzer is fed to an audio analyzer. The 20 kHz lowpass filter of the modulation
analyzer is used to reduce the level of residual high frequency noise. The oscillator level is
adjusted at 1 kHz to obtain 60% of full-system deviation. The oscillator level is then varied over a
range of ±20 dB in 5 dB increments, and the resulting deviation is plotted. This measurement is
repeated at 300 Hz and 3 kHz. The above procedure is performed four times, for conditions with
Tone Private Line, Digital Private Line, Trunking (these are continuous subaudible signaling
formats), and without subaudible signalling (referred to as “carrier squelch mode”).
Occupied Bandwidth
Pursuant to FCC Rules 2.1049
Procedure for Occupied Bandwidth Measurement for Voice Transmission
The transmitter is connected, via a suitable attenuator, to the spectrum analyzer. The spectrum
analyzer settings for the reference calibration are in accordance with 47 CFR 90.210(d)(4). The
unmodulated carrier’s emission spectrum is captured on the spectrum analyzer and then used to
establish a 0 dB reference plot for exhibits.
The audio source is connected to the microphone audio input of the transmitter. The audio
source frequency is set to 2500 Hz and the amplitude is adjusted to a level 16 dB above that
required to produce 50% of full system deviation at the frequency of maximum response of the
audio modulation circuit, in accordance with 47 CFR Part 2.1049(c)(1). The spectrum analyzer
settings are adjusted in accordance with 47 CFR 90.210(d)(4) and the analyzer is swept to record
the resultant emission levels using the appropriate emission mask.
This measurement is repeated with Tone Private Line (TPL) sub-audible signaling and audio by
adding a 250.3 Hz TPL tone at 15% full system deviation with the previously defined 2500 Hz
tone. The amplitude of the modulating signal is adjusted so that the total deviation, which
includes the TPL deviation, is the full system deviation. An additional measurement is made with
Digital Private Line (DPL) sub-audible signaling and audio by adding a DPL code 131 at 15% full
system deviation with the previously defined 2500 Hz tone. The amplitude of the modulating
signal is adjusted so that the total deviation, which includes the DPL deviation, is the full system
deviation.
Procedure for Occupied Bandwidth Measurement for 2000/3000 Hz FSK Data
The transmitter is connected, via a suitable attenuator to spectrum analyzer. The spectrum
analyzer settings for the reference calibration are in accordance with 47 CFR 90.210(d)(4). The
unmodulated carrier’s emission spectrum is captured on the spectrum analyzer and then used to
establish a 0 dB reference plot for exhibits.
The audio function generator is connected to the flat (non-pre-emphasized) transmit audio input
of the radio under test. A second function generator producing a square wave output at a
frequency of 1200 Hz is connected to the voltage control input of the first generator. The first
generator is set to produce a sine wave signal at a center frequency of 2500 Hz and the
amplitude of the square wave from the second generator is adjusted so that the frequency of the
first generator is varied ± 500 Hz. The resulting output of the first generator is an AFSK sine
wave signal that shifts between two discrete frequencies, 2000 Hz and 3000 Hz, at a rate of 1200
Hz. The amplitude of the first generator, which modulates the transmitter, is adjusted for full

system deviation. The spectrum analyzer settings are adjusted in accordance with 47 CFR
90.210(d)(4) and the analyzer is swept to record the resultant emission levels using the
appropriate emission mask.
This measurement is repeated with Tone Private Line (TPL) sub-audible signaling and 2000/3000
Hz FSK data by adding a 250.3 Hz TPL tone at 15% full system deviation with the previously
defined data signal. The amplitude of the modulating signal is adjusted so that the total deviation,
which includes the TPL deviation, is the full system deviation. An additional measurement is
made with Digital Private Line (DPL) sub-audible signaling and 2000/300 Hz FSK data by adding
a DPL code 131 at 15% full system deviation with the previously defined 2500 Hz tone. The
amplitude of the modulating signal is adjusted so that the total deviation, which includes the DPL
deviation, is the full system deviation.
Procedure for Occupied Bandwidth Measurement for DTMF
The transmitter is connected, via a suitable attenuator, to the spectrum analyzer. The spectrum
analyzer settings for the reference calibration are in accordance with 47 CFR 90.210(d)(4). The
unmodulated carrier’s emission spectrum is captured on the spectrum analyzer and then used to
establish a 0 dB reference plot for exhibits.
The transmitter is keyed up and the “#” key pressed to generate the worst-case DTMF tones (941
Hz and 1633 Hz). The spectrum analyzer settings are adjusted in accordance with 47 CFR
90.210(d)(4) and the analyzer is swept to record the resultant emission levels using the
appropriate emission mask.
This measurement is repeated with Tone Private Line (TPL) sub-audible signaling and DTMF by
adding a 250.3 Hz TPL tone at 15% full system deviation with the previously defined DTMF
signal. An additional measurement is made with Digital Private Line (DPL) sub-audible signaling
and DTMF by adding a DPL code 131 at 15% full system deviation with the previously defined
DTMF signal.
Procedure for Occupied Bandwidth Measurement for 4-Level FSK Data
The transmitter is connected, via a suitable attenuator, to the spectrum analyzer. The spectrum
analyzer settings for the reference calibration are in accordance with 47 CFR 90.210(d)(4). The
unmodulated carrier’s emission spectrum is captured on the spectrum analyzer and then used to
establish a 0 dB reference plot for exhibits.
The radio is placed in test mode such that it transmits a 511-bit pseudo-random bit sequence
based on ITU-T O.153 in the 2:1 TDMA protocol’s payload, which is in accordance to 47 CFR
2.1049(h). The spectrum analyzer settings are adjusted in accordance with 47 CFR 90.210(d)(4)
and the analyzer is swept to record the resultant emission levels using the appropriate emission
mask.
Conducted Spurious Emissions
Pursuant to FCC Rule 2.1051
The output of the transmitter is connected, via a suitable attenuator, to the input of an spectrum
analyzer. The level of spurious emissions, in dBm, is plotted. This data is measured at the lower,
middle, and upper frequency limits of the frequency range. Since the transmit power is adjustable,
the measurement is repeated at various power levels including minimum and maximum.
Note:
RBW setting is adjusted to 100kHz for both Part 22 and RSS 119.

Radiated Spurious Emissions
Pursuant to FCC Rules 2.1053
Transmitter radiated spurious emissions were measured by the Motorola Plantation OATS (Open
Area Test Site) Lab, located at 8000 West Sunrise Blvd, Plantation, Florida 33322.
Measurements were made at an approved open field test site constructed in accordance with
Appendix B, FCC/OST 55 (1982), and were performed in accordance with the Code of Federal
Regulations, Title 47, Part 2, paragraph 2.1053. The data is plotted as “Radiated Spurious and
Harmonic Emissions (Horizontal and Vertical)” on the graphs comprising EXHIBIT 6G. The
specification limit corresponding to a level of 43 dB + 10 log (Pout) below the fundamental carrier
power of the transmitter is indicated on each graph for reference.
Radiated Spurious and Harmonic Emissions were performed by:

Note:
RBW setting is adjusted to 100kHz for both Part 22 and RSS 119.
Frequency Stability
Pursuant to FCC Rule 2.1055
A. Temperature (Non-heated type crystal oscillators):
Frequency measurements are made at the extremes of the temperature range -30 to +60
degrees centigrade and at intervals of not more than 10 degrees centigrade throughout
the range. Sufficient time is allowed prior to each measurement for the circuit
components to stabilize.
B. Power Supply Voltage:
The primary voltage was varied from 85% to 115% of the nominal supply voltage. Voltage
is measured at the input to the cable normally provided with the equipment, or at the
power supply terminals if cables are not normally provided.
Transient Frequency Behavior
Pursuant to FCC Rule 90.214
This data measured in accordance with FCC Rules. Applicable method of measurement and
definition can be found in Section 2.2.19 of the TIA/EIA 603D. Specifically, the triggering level
was set in the following manner.
The output of the radio is connected to an modulation analyzer by way of a directional coupler,
30dB attenuator, and 2:1 combining network. This output is first measured with an power meter
and then the power meter is replaced by the modulation analyzer, and the RF output of a signal
generator is connected to the second port of the combining network at a level of 30dB less than
the output level of the radio measured after the attenuator. The RF output of the signal generator
is modulated with a 1kHz tone and deviation of 12.5kHz or 25kHz depending on the channel

spacing. The modulation output of the modulation analyzer is connected to a digital storage
oscilloscope. The signal generator is turned on first, and then the radio keyed or de-keyed
depending on the particular test. The oscilloscope is triggered by way of a RF peak detector that
detects the RF output of the radio by way of the directional coupler.
The picture of the oscilloscope display is stored on a floppy disk and transferred to a computer.
The key up attack time plot shows the 1kHz from the RF signal generator signal from the
modulation output of the modulation analyzer, and when the radio is keyed, the output signal from
the radio captures the receiver of the modulation analyzer, resulting in the carrier only signal. The
de-key decay time plots show the unmodulated signal from the radio and when the radio is de-
keyed, the 1kHz from the RF signal generator signal captures the receiver of the modulation
analyzer, resulting in the 1kHz signal shown in the plots.
