 1.9 Test Procedure
 General
 The hd43 remote – EUT hereafter, is connected to the hdHost in a manner consistent with a
 typical installation. A digital modulation signal generator is connected to the TX_IN port of
 the appropriate band of the hdHost and spectrum analyzer is connected to the corresponding
 EUT downlink antenna port through an attenuator, nominally 40 dB for the band under
 consideration.

 The 700 MHz (728 – 757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995 MHz) and
 AWS (2110-2155 MHz) band was investigated. Measurements were performed with two types
 of test signals recommended by FCC KDB 935210 D05 v01r01. A quote is shown below:

 3.0 Test Methods for CMRS Non-Consumer Repeater/Amplifier and Industrial Booster Devices
 3.1 General
 Commercial Mobile Radio Services (CMRS) non-consumer RF repeaters, amplifiers, and industrial boosters shall be tested for compliance
 with the applicable regulatory technical requirements. Input and output power and emissions measurements must be performed using test
 signals that are intended to bound the typical signal space encountered within the CMRS bands. Broadband amplifiers/boosters shall be tested
 using a representative band-limited AWGN signal. The AWGN test signal must have a 4.1 MHz 99 % occupied bandwidth (OBW)
 (representative of a 5 MHz LTE channel). Narrowband test signals shall use a representative MSK modulated signal, with a Gaussian Filter of
 0.3 and a data rate of 270 kbps (representative of a GSM-TDMA signal).


 In the tests reported here the LTE and GSM signals were used as the two test signal
 representatives:
        - LTE (5MHz channel bandwidth representing wide band signal) and
        - GSM (GMSK modulation with a Gaussian Filter of 0.3 and a data rate o 270kbs
            representing narrow band signal of about 200kHz bandwidth)

AGC Threshold Level
The measurement procedure used was KDB 935210 D05. AGC threshold level is measured by
connecting a Spectrum Analyzer to the RF antenna port via an attenuator and a Signal
Generator to the supporting device – hdHost RF source port.
A GSM signal was generated on the center frequency of the operating band under test. The
integrated Channel Power over the channel bandwidth was measured using resolution
bandwidth (RBW) equals to 1% of the emission bandwidth. AGC threshold level was
determined when increasing the input signal amplitude 0.5dB will no longer cause 0.5dB
increase in the output signal amplitude.

Out of Band Rejection
The measurement procedure used was KDB 935210 D05. The Signal Generator sent CW
signal sweep in the range of ±250% of the passband. So is the Spectrum Analyzer span was set
to. The RBW was set to 5% of the passband. An input signal level 5dB below the AGC
threshold was injected. Two traces were obtained, via Max-Hold and Clear-Write. The peak
frequency in the Max-Hold trace was recorded and would be allocated for the system gain and
output power measurement.

Occupied Bandwidth – Input versus Output Signal Comparison
The measurement procedure used was KDB 935210 D05. Occupied Bandwidth is measured
by connecting a Spectrum Analyzer to the RF output connector.
The required measurement RBW is 1% of the emission bandwidth. 99% energy rule was
applied to measure the occupied channel bandwidth. The emission bandwidth is measured as
the width of the signal between two frequency points on the channel edge, outside of which
the transmission power is attenuated at least 26dB below the transmitter output power. The
carrier allocated on the center frequency of the passband was investigated with input
amplitude 0.5dB below the AGC threshold, for both input and output signal occupied band
width. The output was then measured again with input amplitude 3dB above the AGC
threshold.

RF Power Output
The measurement procedure used was KDB 971168 D01 Section 5.2.1. The EUT was
configured to transmit continuously. RF power is measured by connecting a Spectrum
Analyzer to the RF output connector. With an input power 0.5dB below and 3dB above the
AGC threshold, respectively, the RF output is measured via Spectrum Analyzer’s channel

power function. The carrier was located at the peak frequency obtained in the out of band
rejection measurement.

Out of Block Emissions
The measurement procedure used was KDB 935210 D05. The out of block emission was
measured under two stimulus conditions. 1). Two adjacent test signal sequentially tuned to the
lower and upper band edges; 2). A single test signal, sequentially tuned to the lowest and
highest channels within the operating band. The intermodulation emission out of block was
produced by the two carrier test signal as well. The peak emission was measured in 100kHz or
1MHz integrated bandwidth within 300kHz or 3MHz span immediate out of band, for carriers
below or above 1GHz, respectively. The input power was set with two amplitude levels, i.e.
0.5dB below and 3dB above the AGC threshold level.

Spurious Emissions
The procedure used was ANSI/TIA-603-C: 2004. The spectrum was scanned from 9 kHz to at
least the tenth harmonic of the fundamental using a spectrum analyzer. For digital modulation,
the carrier is modulated to its maximum extent. The measurements were made in accordance
with standard ANSI/TIA-603-C: 2004. The input power was set 0.5dB below the AGC
threshold level. Simultaneous three carriers were allocated on the lowest, center and highest
channels. The spurious emissions were then measured in the above range exclude the
operating band ± 300kHz or ± 3MHz, in a reference bandwidth of 100kHz or 1MHz, for
carriers below or above 1GHz, respectively.

Intermodulation Product Spurious Emissions
The procedure used was ANSI/TIA-603-C: 2004 and KDB 971168 D03. Three tones
(modulated) method was used. Two tones are close to each other on the one edge and the third
one is alone on the other edge of the passband. The input power to the amplifier was set to
0.5dB below the AGC threshold level by combining the three tones. The intermodulation
product emissions were measured in band and spurious emissions were measured out of band.


1.10 Operational Description
Dali Matrix™ is a modular, end-to-end digital RF distribution system.
Matrix is implemented in two tiers:
        Modular Universal Base Station Interface Tray (UBiT) functioning as a headend
        Modular digital remote units are for indoor and outdoor deployments.
A single optical fiber interface, based on the CPRI protocol, is used to connect the UBiT
digital Host module with a number of hd30/37/43 remote units, in a star, daisy-chain, or
hybrid star/daisy-chain configuration. The digital remote units can be installed up to 20km
away from the UBiT headend. Both headend and remote units contain a digital processing
section and an RF processing section.
The UBit integrated headend typically interface RF signals with Base Stations via coaxial RF
cables or digital baseband signal via optical fibers.




                                              10


The remote unit hd43, which is the EUT in this test report is a quad band unit with 20 W
average output power per band. Bands supported and scope of the requested license is as
follows:
      Lower and Upper 700 MHz Band: 27.5(c), 27.50(c), 27.53(c,g)
      Cellular Band: 22.905, 22.913, 22.917
      AWS-1 Band: 27.5(h), 27.50(d), 27.53(h)
      Broadband PCS Band: 24.229, 24.232, 24.238


The band set that particular remote unit support is determined by the type of module that is
installed in the unit, each containing frequency of operation limiting duplex filters and RF
band specific filters.
It is marketed for commercial cellular applications. All band support broadband 2G, 3G, and
4G waveforms.
To maintain declared output power, and to prevent Power Amplifier (PA) to go into saturation
condition, Automated Level Control (ALC) circuitry is implemented inside power amplifier
section. The ALC circuitry monitors PA output power via built in average power detector, and
if detected output power level is above threshold (set during manufacturing process),
introduces attenuation in a PA lineup (PA gain reduction) that is equivalent to power
difference between detected power and threshold power, hence maintains output power at
level equal to ALC threshold level. The ALC attenuation range is from 0 dB to 30 dB. The
ALC threshold level is set 1 dB above the declared maximum average output power, thus to
+44 dBm in a case of the hd43 remote unit. Once the output power is detected above this
threshold, certain attenuation will be set to draw the output down to 43dBm.

2 AGC Threshold Level
2.1 Methodology
Measurements were performed at narrow band single carrier for the center frequency within
the 700 MHz (728 – 757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995 MHz) and
AWS (2110-2155 MHz) band.

Tabular data is shown in section 2.3 for the all bands. The AGC threshold level is to provide
the instruction of input signal amplitude for the emission in conducted measurement address in
this report.

The AGC threshold was determined following test method defined in FCC KDB 935210 D05
(Feb 2016) Section 3.2.

2.2 Interpretation
The equipment under test (EUT) is featured automatic level control (ALC), which
electronically adjusts the output power not exceed a certain maximum level. In order to align
with the measurement guidance, the AGC threshold is used throughout the report, representing
the ALC trip point (input power).
At amplitude above the AGC threshold, an increase of 1dB in the input power will no longer
cause a 1dB increase in the output signal power.

3 Out-of-band Rejection
3.1 Methodology
Measurements were performed at CW signal sweep in a frequency range of 5 times the
operating bandwidth centered at the operating band. The operating bands are 700 MHz (728 –
757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995 MHz) and AWS (2110-2155 MHz)
on the downlink – transmitting direction - where the air interface exists.
The measurement procedure follows the KDB 935210 D05 Section 3.3. The input power level
was set 5dB lower than the AGC threshold level, so that no output suppression occurred in any
of the EUT bands. 20dB down bandwidth was measured compared to the peak power in-band.
The peak power frequency was recorded and would be used to check the EUT output power.

Occupied bandwidth (OBW) of input and output signal is shown in Figure 4-1 and Figure 4-2
side by side for the four operating bands. The output OBW was tested under two input
conditions:
        - Nominal: with input 0.5dB below AGC threshold
        - AGC: with input 3dB above AGC threshold

A brief summary of applicable FCC specifications is listed in the table below.

Conclusion:
There is no change of the OBW comparing input and output signal. There is also no change of the
OBW in the output signal when the EUT is working under AGC active or inactive status.
The maximum deterioration observed is less than 3.3% of the input signal.

5 Output Power
5.1 Methodology
Measurements were performed at narrow band and wide band signal for the peak output power
within the 700 MHz (728 – 757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995 MHz)
and AWS (2110-2155 MHz) band. Measurement method was following KDB 935210 D05
Section 3.4 and KDB 971168 D01 Section 5.2.1.

Average output power is shown in the Figure 5-1and Figure 5-2 for the four operating bands.
The output power was tested under two input conditions:
       - Nominal: with input 0.5dB below AGC threshold
       - AGC: with input 3dB above AGC threshold

A brief summary of applicable FCC specifications is listed in the table below.

2.1046 Measurements required: RF power output.
(a) For transmitters other than single sideband, independent sideband and controlled carrier radiotelephone, power output shall be measured at
the
RF output terminals when the transmitter is adjusted in accordance with the tune-up procedure to give the values of current and voltage on the
circuit elements specified in § 2.1033(c)(8). The electrical characteristics of the radio frequency load attached to the output terminals when
this test is made shall be stated.


5.2 Interpretation
The peak output power was allocated in the previous out-of-band rejection test. In the case that
a full channel cannot accommodate in-band by setting the carrier frequency to the exact peak
frequency, the test carrier location was moved inward to the first applicable channel.

6 Emission at Antenna Terminal
6.1 Methodology
All test conditions and measurement procedures were performed in accordance with FCC
CFR47 part 2 subpart J Clause 2.1051. Detailed measurement method was following KDB
935210 D05 Section 3.6.

A brief summary of the applicable FCC specifications are listed in the table below.
2.1051 Measurements required: Spurious emissions at antenna terminals.
The radio frequency voltage or powers generated within the equipment and appearing on a spurious frequency shall be checked at the
equipment output terminals when properly loaded with a suitable artificial antenna. Curves or equivalent data shall show the magnitude of
each harmonic and other spurious emission that can be detected when the equipment is operated under the conditions specified in§ 2.1049 as
appropriate. The magnitude of spurious emissions which are attenuated more than 20 dB below the permissible value need not be specified.

2.1057 Frequency spectrum to be investigated.
(a) In all of the measurements set forth in §§ 2.1051 and 2.1053, the spectrum shall be investigated from the lowest radio frequency signal
generated in the equipment, without going below 9 kHz, up to at least the frequency shown below:
(1) If the equipment operates below 10 GHz: to the tenth harmonic of the highest fundamental frequency or to 40 GHz, whichever is lower.

27.53 Emission limits.
(c) (1) For operations in the 746-758 MHz band and the 776-788 MHz band, the power of any emission outside the licensee's frequency
band(s) of operation shall be attenuated below the transmitter power (P) within the licensed band(s) of operation, measured in watts, in
accordance with the following:
On any frequency outside the 746-758 MHz band, the power of any emission shall be attenuated outside the band below the transmitter power
(P) by at least 43 + 10 log (P) dB
(g)For operations in the 600 MHz band and the 698-746 MHz band, the power of any emission outside a licensee's frequency band(s) of
operation shall be attenuated below the transmitter power (P) within the licensed band(s) of operation, measured in watts, by at least 43 + 10
log (P) dB. Compliance with this provision is based on the use of measurement instrumentation employing a resolution bandwidth of 100
kilohertz or greater. However, in the 100 kilohertz bands immediately outside and adjacent to a licensee's frequency block, a resolution
bandwidth of at least 30 kHz may be employed.
(h) For operations in the 1710–1755 MHz and 2110–2155 MHz bands, the power of any emission outside a licensee’s frequency block shall
be attenuated below the transmitter power (P) by at least 43 + 10 log10 (P) dB.
(1) Compliance with this provision is based on the use of measurement instrumentation employing a resolution bandwidth of 1 megahertz or
greater. However, in the 1 megahertz bands immediately outside and adjacent to the licensee’s frequency block, a resolution bandwidth of at
least one percent of the emission bandwidth of the fundamental emission of the transmitter may be employed. The emission bandwidth is
defined as the width of the signal between two points, one below the carrier center frequency and one above the carrier center frequency,
outside of which all emissions are attenuated at least 26 dB below the transmitter power.

22.917 Emission limits.
(a) Out of band emissions. The power of any emission outside of the authorized operating frequency ranges must be attenuated below the
transmitting power (P) by a factor of at least 43 + 10 log(P) dB.

24.238 Emission limitations for Broadband PCS equipment.
(a) Out of band emissions. The power of any emission outside of the authorized operating frequency ranges must be attenuated below the
transmitting power (P) by a factor of at least 43 + 10 log(P) dB.
The limit is = -13 dBm.

6.2     Out-of-band Emission

6.2.1 Measurement Configuration
Measurements were performed at narrow band and wide band signal at the lower and upper
edge within the 700 MHz (728 – 757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995
MHz) and AWS (2110-2155 MHz) band.




                                                                     23


Tests were repeated for single carrier and adjacent dual carriers, as defined in 3GPP, on first
and last channel in the operating bands.

For each type of signal applied, tests were again repeated under two input conditions:
       - Nominal: with input 0.5dB below AGC threshold
       - AGC: with input 3dB above AGC threshold
The out-of-band emission was measured within specified frequency range at the edge of the
authorized frequency band, 300kHz range for the frequency band below 1GHz and 3MHz
range for the one above 1GHz. Normally the reference band width (RBW) in spurious
emission measurement was specified to 100kHz for the frequency range below 1GHz and
1MHz for the frequency range above 1GHz. A relaxation of RBW is allowed to be applied to
out-of-band emission measurement.

KDB 971168 D01 page14:
This is often implemented by permitting the use of a narrower RBW (typically limited to a minimum RBW of 1% of the OBW) for measuring
the out-of-band emissions without a requirement to integrate the result over the full reference bandwidth. Beyond the specified frequency
range in which this relaxation is permitted, it is also typically acceptable to use a narrower RBW (again limited to a minimum of 1% of OBW)
in order to increase accuracy, but the measurement result must subsequently be integrated over the full reference bandwidth.



6.2.2 Results
The immediate out-of-band emission measurement is shown in the Figure 6-1, Figure 6-2,
Figure 6-3 and Figure 6-4 for the four operating bands.

Conclusion:
The peak out-of-band emission caused by any of the following combination – narrow band
signal vs wide band signal, single carrier vs dual carriers, and nominal input vs input above
AGC threshold - is below -13dBm limit.
