7.5              Peak-Average Ratio
§24.232(d)

Test Overview

A peak to average ratio measurement is performed at the conducted port of the EUT. The spectrum analyzers
Complementary Cumulative Distribution Function (CCDF) measurement profile is used to determine the largest
deviation between the average and the peak power of the EUT in a given bandwidth. The CCDF curve shows how
much time the peak waveform spends at or above a given average power level. The percent of time the signal
spends at or above the level defines the probability for that particular power level.

Test Procedure Used

KDB 971168 D01 v03r01 – Section 5.7.1

Test Settings

      1. The signal analyzer’s CCDF measurement profile is enabled
      2. Frequency = carrier center frequency
      3. Measurement BW ≥ OBW or specified reference bandwidth
      4. The signal analyzer was set to collect one million samples to generate the CCDF curve
      5. The measurement interval was set depending on the type of signal analyzed. For continuous signals (>98%
             duty cycle), the measurement interval was set to 1ms.
Test Setup

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

7.6              Radiated Power (ERP/EIRP)
§22.913(a)(5), §24.232(c)

22.913(a)(5) 24.232(c)

Test Overview

Effective Radiated Power (ERP) and Equivalent Isotropic Radiated Power (EIRP) 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. Measurements on signals operating above 1GHz are performed using vertically and horizontally
polarized broadband horn 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.
      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”.

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

             continuous operation.

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

      10. The trace was allowed to stabilize

Test Notes

      1) The EUT was tested in three orthogonal planes and in all possible test configurations and positioning. The
         worst case emissions are reported with the EUT positioning, modulations, RB sizes and offsets, and
         channel bandwidth configurations shown in the tables below.

      2) This unit was tested with its standard battery.

7.7              Radiated Spurious Emissions Measurements
§2.1053, §22.917(a), §24.238(a)

Test Overview

Radiated spurious emissions 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. Measurements on signals operating
above 1GHz are performed using vertically and horizontally polarized broadband horn antennas.

Test Procedures Used

KDB 971168 D01 v03r01 – Section 5.8

ANSI/TIA-603-E-2016 – Section 2.2.12

Test Settings

      1. RBW = 100kHz for emissions below 1GHz and 1MHz for emissions above 1GHz

      2. VBW ≥ 3 x RBW

      3. Span = 1.5 times the OBW

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

      5. Detector = RMS

      6. Trace mode = Average (Max Hold for pulsed emissions)

      7. The trace was allowed to stabilize




                                                                               MEASUREMENT REPORT                                                                  Approved by:

Test Setup

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




                                                   Figure 7-7. Test Instrument & Measurement Setup

Test Notes

      1) The EUT was tested in three orthogonal planes and in all possible test configurations and positioning. The
         worst case emissions are reported with the EUT positioning, modulations, RB sizes and offsets, and
         channel bandwidth configurations shown in the tables below.

      2) This unit was tested with its standard battery.

      3) The spectrum is measured from 9kHz to the 10th harmonic of the fundamental frequency of the transmitter.
         The worst-case emissions are reported.

      4) Emissions below 18GHz were measured at a 3 meter test distance while emissions above 18GHz were
         measured at a 1 meter test distance with the application of a distance correction factor.

      5) The "-" shown in the following RSE tables are used to denote a noise floor measurement.

7.8              Frequency Stability / Temperature Variation
§2.1055, §22.355, §24.235

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.

For Part 22, the frequency stability of the transmitter shall be maintained within ±0.00025% (±2.5 ppm) of
the center frequency. For Part 24, the frequency stability shall be sufficient to ensure that the fundamental
emission stays within the authorized frequency block.

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

Note:

Based on the results of the frequency stability test at the center channel the frequency deviation results measured
are very small. As such it is determined that the channels at the band edge would remain in-band when the
maximum measured frequency deviation noted during the frequency stability tests is applied. Therefore the device
is determined to remain operating in band over the temperature and voltage range as tested.
