1.1 Introduction

This Conformity test report applies to the AAHE - Small Band 10 MHz, hereinafter referred to as the Equipment Under
Test (EUT).

1.2 Purpose and Scope

The purpose of this document is to provide the testing data required for qualifying the EUT in compliance with FCC Parts
2 and 27 measured in accordance with the procedures set out in Section 2.1033 (c) (14) of the Rules.



1.3 EUT Details

The EUT was tested for Class II Permissive change to add a new low channel frequency (2628.8 MHz), new 10 MHz single
carrier bandwidth, and 20+10 MHz multiple carrier operation to the existing Grant. Multi Carrier operation is restricted to
placement of carriers within a bandwidth of 60 MHz.

2. FCC Section 2.1046 - RF Power Output
2.1 RF Power Output

This test is a measurement of the total RF power level transmitted at the antenna-transmitting terminal. The product was
configured for test as shown in section 1.6 above and allowed to warm up and stabilize per KDB 971168 D01 and ANSI
C63.26.
Power measurements were made with a broadband Power Meter in the average mode. Before the testing was started, the
Base Station was given a sufficient “warm-up” period as required.

3. FCC Section 2.1047 - Modulation Characteristics

3.1 Modulation Characteristics

The RF signal at the antenna port was demodulated and verified for correctness of the modulation signal used before each
test was performed. For these products the operation with QPSK, 16QAM, 64QAM and 256QAM modulation was
evaluated and verified.

4. FCC Section 2.1049 – Occupied Bandwidth
4.1 Occupied Bandwidth
In 47CFR 2.1049 the FCC requires:
      “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.”

This required measurement is the 99% Occupied Bandwidth, also called the designated signal bandwidth and needs to be
within the parameters of the products specified emissions designator. The -26 dB bandwidth values were also recorded.

During these measurements it is customary to evaluate the Edge of Band emissions at block/band edges.

The transmitted signal occupied bandwidth was measured using a Keysight MXA Signal Analyzer. All emissions were
within the parameters as previously filed. Sample Charts are below.

4.2 Occupied Bandwidth/ Edge of band Emissions
The Edge of Band emissions of the EUT at the external antenna connector (EAC) were measured using a Keysight MXA
Signal Analyzer. The RF power level was continuously measured using a RF broadband power meter. The RF output from
the EAC port to spectrum analyzer was reduced (to an amplitude usable by the spectrum analyzer) by using a calibrated
attenuator and test coupler. The path attenuation was offset on the display and the signal for single carrier was adjusted to
the corrected RF power level for the resolution bandwidth used for the transmit signal. All mask values were adjusted based
upon the designated signal bandwidth and measurement bandwidths. The Top of Mask corresponds to the set rated power
level as confirmed by the RF power meter.

4.2.1 Occupied Bandwidth Results.
The Occupied Bandwidth was measured for all three modulations, at each signal bandwidth and at left center and right side
of band. The mask on the plots meet the Block Edge requirements as specified in 47CFR 27.53.

All of the measurements met the requirements of Part 27.53 when measured per Part 2.1049.

5. FCC Section 2.1051 - Spurious Emissions at Transmit Antenna Port

5.1 Measurement of Spurious Emissions at Transmit Antenna Port
Spurious Emissions at the transmit-antenna terminals were investigated over the frequency range of 10 MHz to beyond the
10th harmonic of the specific transmit band. For this band of operation, the measurements were performed up to 27 GHz.
Measurements were made using a Keysight MXA Signal Analyzer. The RF output from the transmitter was reduced (to an
amplitude usable by the receivers) using calibrated attenuators. The RF power level was continuously monitored via a
coupled RF Power Meter.

The required emission limitation is specified as appropriate in 27.53. The measured spurious emission levels were plotted
for the frequency range as specified in 2.1057. There were no reportable emissions. Data below documents performance up
to 27 GHz.

NOTE: Only a sample of all the data taken have been used in this report. The full suite of raw data resides at the MH, New
Jersey location.

                                                                               Product: AAHE - Small Band 10 MHz

6. FCC Section 2.1053

6.1 Section 2.1053 Field Strength of Spurious Emissions
Field strength measurements of radiated spurious emissions were made in 3m Semi-Anechoic Chambers the of Global
Product Compliance Laboratories of Nokia Bell Labs in Murray Hill NJ. A complete description and full measurement data
for the site is on file with the Commission (FCC File 515091).

The spectrum from 30 MHz to beyond the tenth harmonic of the carrier, 27 GHz, was searched for spurious radiation.
Measurements were made using both horizontally and vertically polarized broadband antennas. Per FCC regulations, the
comparison of out of band spurious emissions directly to the limit is appropriately made using the substitution method.
However, when the emissions are more than 20 dB below the specification limit, the use of field strength measurements for
compliance determination is acceptable and those emissions are considered not reportable (Section 2.1053 and the FCC
Interpretive database for 2.1053). For this case the evaluation of acceptable radiated field strength is as follows.


6.2 Field Strength of Spurious Emissions - Limits

Sections 2.1053 and 27.53 contain the requirements for the levels of spurious radiation as a function of the level of the
unmodulated carrier. The reference level for the unmodulated carrier is calculated as the field produced by an ideal dipole
excited by the transmitter output power according to the following relation taken from Reference Data for Radio Engineers,
page 676, 4th edition, IT&T Corp.

                                                     E= [(30*P)1/2]/R

                                   20 log (E*106) – (43 + 10 log P) = 82.23 dBV/meter
Where:
E = Field Intensity in Volts/meter       P = Transmitted Power in Watts
R = Measurement distance in meters = 3 m

The Part 27 Limit is 82.23 dBuV/m at 3m and 91.77 dBuV/m at 1m
The Part 27 non-report level is 62.23 dBuV/m at 3m.


The calculated emission levels were found by:

                  Measured level (dBV) + Cable Loss(dB)+Antenna Factor(dB) = Field Strength (dBV/m)

RESULTS:
 For compliance with 47CFR Parts 2 and 27, the field strength of any spurious radiation, measured at 3m, is required to
 be less than 82.23 dBV/meter (82.23 @ 3m). Emissions equal to or less than 62.23 dBV/meter at 3m are not reportable
 and may be verified using field strength measurements and broadband antennas. Over the out of band spectrum
 investigated from 30 MHz to beyond the tenth harmonic of the carrier (up to 27GHz), no reportable spurious emissions
 were detected.
