3.0           DESCRIPTION OF TESTS

 3.1           Evaluation Procedure
 The measurement procedures described in the document titled “Land Mobile FM or PM – Communications
 Equipment – Measurements and Performance Standards” (ANSI/TIA-603-E-2016) and “Procedures for
 Compliance Measurement of the Fundamental Emission Power of Licensed Wideband (> 1 MHz) Digital
 Transmission Systems” (KDB 971168 D01 v03r01) were used in the measurement of the EUT.

 3.2           Radiated Power and Radiated Spurious Emissions
 §2.1053, §90(R)
 The radiated test facilities consisted of an indoor 3 meter semi-anechoic chamber used for final measurements
 and exploratory measurements, when necessary. The measurement area is contained within the semi-anechoic
 chamber which is shielded from any ambient interference. The test site inside the chamber is a 6m x 5.2m
 elliptical, obstruction-free area in accordance with Figure 5.7 of Clause 5 in ANSI C63.4-2014. Absorbers are
 arranged on the floor between the turn table and the antenna mast in such a way so as to maximize the reduction
 of reflections for measurements above 1GHz. For measurements below 1GHz, the absorbers are removed. A
 raised turntable is used for radiated measurement. The turn table is a continuously rotatable, remote-controlled,
 metallic turntable and 2 meters (6.56 ft.) in diameter. The turn table is flush with the raised floor of the chamber in
 order to maintain its function as a ground plane. An 80cm tall test table made of Styrodur is placed on top of the
 turn table. A Styrodur pedestal is placed on top of the test table to bring the total table height to 1.5m.
 The equipment under test was transmitting while connected to its integral antenna and is placed on a wooden
 turntable 80cm above the ground plane and 3 meters from the receive antenna. The receive antenna height is
 adjusted between 1 and 4 meter height, the turntable is rotated through 360 degrees, and the EUT is manipulated
 through all orthogonal planes representative of its typical use to achieve the highest reading on the receive
 spectrum analyzer. Radiated power levels are also investigated with the receive antenna horizontally and
 vertically polarized. The maximized power level is recorded using the spectrum analyzer “Channel Power”
 function with the integration band set to the emissions’ occupied bandwidth, a RMS detector, RBW = 100kHz,
 VBW = 300kHz, and a 1 second sweep time over a minimum of 10 sweeps, per the guidelines of KDB 971168
 D01 v03r01.
 Per the guidance of ANSI/TIA-603-E-2016, a half-wave dipole is then substituted in place of the EUT. For
 emissions above 1GHz, a horn antenna is substituted in place of the EUT. The substitute antenna is driven by a
 signal generator with the level of the signal generator being adjusted to obtain the same receive spectrum
 analyzer level previously recorded from the spurious emission from the EUT. The power of the emission is
 calculated using the following formula:
                                                   Pd [dBm] = Pg [dBm] – cable loss [dB] + antenna gain [dBd/dBi]
 Where, Pd is the dipole equivalent power, Pg is the generator output into the substitution antenna, and the
 antenna gain is the gain of the substitute antenna used relative to either a half-wave dipole (dBd) or an isotropic
 source (dBi). The substitute level is equal to Pg [dBm] – cable loss [dB].

 For fundamental radiated power measurements, the guidance of KDB 971168 D01 v03r01 is used to record the
 EUT power level that is subsequently matched via the aforementioned substitution method given in ANSI/TIA-
 603-E-2016.

 All radiated measurements are performed in a chamber that meets the site requirements per ANSI C63.4-2014.
 Additionally, radiated emissions below 30MHz are also validated on an Open Area Test Site to assert correlation
 with the chamber measurements per the requirements of KDB 474788 D01.

 Spurious Radiated Emission – LTE Band
 The average spectrum analyzer reading at 3 meters with the EUT on the turntable was –81.0 dBm. The gain of
 the substituted antenna is 8.1 dBi. The signal generator connected to the substituted antenna terminals is
 adjusted to produce a reading of –81.0 dBm on the spectrum analzyer. The loss of the cable between the signal
 generator and the terminals of the substituted antenna is 2.0 dB at 1564 MHz. So 6.1 dB is added to the signal
 generator reading of –30.9 dBm yielding –24.80 dBm. The fundamental EIRP was 25.501 dBm so this harmonic
 was 25.501 dBm – (-24.80).

           1)     All modes of operation and data rates were investigated. The test results shown in the following sections represent
                  the worst case emissions.
           2)     The analyzer plots shown in Section 7.0 were taken with a correction table loaded into the analyzer. The correction
                  table was used to account for the losses of the cables, directional couplers, and attenuators used as part of the
                  system to maintain a link between the call box and the EUT at all frequencies of interest.
           3)     All antenna port conducted emissions testing was performed on a test bench with the antenna port of the EUT
                  connected to the spectrum analyzer through calibrated cables, attenuators, and couplers.
           4)     For conducted spurious emissions, automated test software was used to measure emissions and capture the
                  corresponding plots necessary to show compliance. The measurement software utilized is PCTEST “2G/3G
                  Automation,” Version 3.9.

7.2           Occupied Bandwidth
§2.1049

Test Overview

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. All modes of operation were investigated and the worst case configuration
results are reported in this section.

Test Procedure Used

KDB 971168 D01 v03r01 – Section 4.2

Test Settings

      1. The signal analyzer’s automatic bandwidth measurement capability was used to perform the 99%
             occupied bandwidth and the 26dB bandwidth. The bandwidth measurement was not influenced by any
             intermediate power nulls in the fundamental emission.
      2. RBW = 1 – 5% of the expected OBW

      3. VBW ≥ 3 x RBW

      4. Detector = Peak

      5. Trace mode = max hold

      6. Sweep = auto couple

      7. The trace was allowed to stabilize

      8. If necessary, steps 2 – 7 were repeated after changing the RBW such that it would be within

             1 – 5% of the 99% occupied bandwidth observed in Step 7

Test Setup

The EUT and measurement equipment were set up as shown in the diagram below.

7.3           Spurious and Harmonic Emissions at Antenna Terminal
§2.1051 §90(R)

Test Overview

The level of the carrier and the various conducted spurious and harmonic frequencies is measured by means of a
calibrated spectrum analyzer. The spectrum is scanned from the lowest frequency generated in the equipment up
to a frequency including its 10th harmonic. All out of band emissions are measured with a spectrum analyzer
connected to the antenna terminal of the EUT while the EUT is operating at maximum power, and at the
appropriate frequencies. All data rates were investigated to determine the worst case configuration. All modes of
operation were investigated and the worst case configuration results are reported in this section.

The minimum permissible attenuation level of any spurious emission is 43 + 10 log10(P[Watts]), where P is
the transmitter power in Watts.

Test Procedure Used

KDB 971168 D01 v03r01 – Section 6.0

Test Settings

      1. Start frequency was set to 30MHz and stop frequency was set to 10GHz (separated into at least two plots
         per channel)
      2. RBW ≥ 100kHz
      3. VBW ≥ 3 x RBW
      4. Detector = RMS
      5. Trace mode = max hold
      6. Sweep time = auto couple
      7. The trace was allowed to stabilize

Test Setup

The EUT and measurement equipment were set up as shown in the diagram below.

7.5          Radiated Power (ERP)
§90.542(a)(7)

Test Overview

Effective Radiated Power (ERP) measurements are performed using the substitution method described in
ANSI/TIA-603-E-2016 with the EUT transmitting into an integral antenna. Measurements on signals operating
below 1GHz are performed using vertically and horizontally polarized tuned dipole antennas. All measurements
are performed as RMS average measurements while the EUT is operating at its maximum duty cycle, at
maximum power, and at the appropriate frequencies.

Test Procedures Used

KDB 971168 D01 v03r01 – Section 5.2.1

ANSI/TIA-603-E-2016 – Section 2.2.17

Test Settings

      1. Radiated power measurements are performed using the signal analyzer’s “channel power” measurement
             capability for signals with continuous operation. For signals with burst transmission, the signal analyzer’s
             “time domain power” measurement capability is used
      2. RBW = 1 – 5% of the expected OBW, not to exceed 1MHz

      3. VBW ≥ 3 x RBW

      4. Span = 1.5 times the OBW

      5. No. of sweep points > 2 x span / RBW

      6. Detector = RMS

      7. Trigger is set to “free run” for signals with continuous operation with the sweep times set to “auto”. Trigger

             is set to enable triggering only on full power bursts with the sweep time set less than or equal to the

             transmission burst duration

      8. The integration bandwidth was roughly set equal to the measured OBW of the signal for signals with

             continuous operation. For signals with burst transmission, the “gating” function was enabled to ensure

             that measurements are performed during times in which the transmitter is operating at its maximum

             power

      9. Trace mode = trace averaging (RMS) over 100 sweeps

      10. The trace was allowed to stabilize




                                                                                MEASUREMENT REPORT                                                              Approved by:

7.7           Frequency Stability / Temperature Variation
§2.1055 §90.213

Test Overview and Limit

Frequency stability testing is performed in accordance with the guidelines of ANSI/TIA-603-E-2016. The
frequency stability of the transmitter is measured by:

a.)       Temperature: The temperature is varied from -30°C to +50°C in 10°C increments using an environmental
          chamber.

b.)       Primary Supply Voltage: The primary supply voltage is varied from 85% to 115% of the nominal value for
          non hand-carried battery and AC powered equipment. For hand-carried, battery-powered equipment,
          primary supply voltage is reduced to the battery operating end point which shall be specified by the
          manufacturer.

The frequency stability of the transmitter shall be maintained within ±0.00025% (±2.5 ppm) of the center
frequency.

Test Procedure Used

ANSI/TIA-603-E-2016

Test Settings

      1. The carrier frequency of the transmitter is measured at room temperature (20°C to provide a reference).
      2. The equipment is turned on in a “standby” condition for fifteen minutes before applying power to the
         transmitter. Measurement of the carrier frequency of the transmitter is made within one minute after
         applying power to the transmitter.
      3. Frequency measurements are made at 10°C intervals ranging from -30°C to +50°C. A period of at least
         one half-hour is provided to allow stabilization of the equipment at each temperature level.

Test Setup

The EUT was connected via an RF cable to a spectrum analyzer with the EUT placed inside an environmental
chamber.

Test Notes

None
