Grandstream Networks, Inc.                                                                    FCC ID: YZZHT502V2X


2. Technical Test
2. 1 Summary of Test Results

                    The EUT has been tested according to the following specifications:
                      Standard                        Test Type       Result           Notes
               FCC Part 15, Paragraph 15.107                   Conducted Test      PASS               Complies
               FCC Part 15, Paragraph 15.109                    Radiated Test      PASS               Complies


2. 2 Measurement Uncertainty
Where relevant, the following measurement uncertainty levels have been estimated for tests performed on the EUT as
specified in CISPR 16-4-2:
           Measurement                               Frequency                                 Uncertainty
        Conducted emissions                      0.15MHz~30MHz                                     1.72
         Radiated emissions                      30MHz ~ 300MHz                                    3.88
         Radiated emissions                     300MHz ~1000MHz                                    3.86

This uncertainty represents an expanded uncertainty expressed at approximately the 95% confidence level using a coverage
factor of k=2.

Consistent with industry standard (e.g. CISPR 22: 2006, clause 11, Measurement Uncertainty) determining compliance with
the limits shall be base on the results of the compliance measurement. Consequently the measure emissions being less than
the maximum allowed emission result in this be a compliant test or passing test.

The acceptable measurement uncertainty value without requiring revision of the compliance statement is base on conducted
and radiated emissions being less than UCISPR which is 3.6dB and 5.2dB respectively. KMO values (called ULab in CISPR
16-4-2) is less than UCISPR as shown in the table above.
Therefore, MU need not be considered for compliance.


3. Modifications
This product is an extension of original report under FCC ID: YZZHT502V2X
The applicant declare that the reasons for this Class II permissive change as below:
1. Changed brand of network transformer.
2. Add two power adapter(Model:F06US1200050A/NBS05B120050VU)and has the same electrical specification with
original power adapter
3. Removed a ferrite core on Ethernet cable.
Anything else are the same as before.

Grandstream Networks, Inc.                                                                   FCC ID: YZZHT502V2X



4. Conducted Power Line Test
4. 1 Test Equipment
Please refer to Section 8 this report.


4. 2 Test Procedure
The EUT and simulators are connected to the main power through a line impedance stabilization network (L.I.S.N.). This
provides a 50 ohm/50uH coupling impedance for the measuring equipment. The peripheral devices are also connected to the
main power through a LISN that provides a 50ohm/50uH coupling impedance with 50ohm termination.

Both sides of A.C. line are checked for maximum conducted interference. In order to find the maximum emission., the
relative positions of equipment and all of the interface cables must be changed according to ANSI C63.4:2014 on conducted
measurement. Conducted emissions were invested over the frequency range from 0.15MHz to 30MHz using a receiver
bandwidth of 9kHz.

5. Radiated Emission Test
5. 1 Test Equipment
Please refer to Section 8 this report.


5. 2 Test Procedure

1. The EUT was tested according to ANSI C63.4:2014.
2. The EUT, peripherals were put on the turntable which table size is 1m x 1.5 m, table high 0.8 m, and which is 1.5 m high
   for above 1 GHz. All set up is according to ANSI C63.4:2014 .
3. The frequency spectrum from 9 kHz to 25 GHz was investigated. All readings from 9 kHz to 150 kHz are quasi-peak
   values with a resolution bandwidth of 200 Hz. All readings from 150 kHz to 30 MHz are quasi-peak values with a
   resolution bandwidth of 9 KHz. All readings from 30 MHz to 1 GHz are quasi-peak values with a resolution bandwidth of
   120 KHz. All readings are above 1 GHz , peak values with a resolution bandwidth of 1 MHz . Measurements were made
   at 3 meters.
4. The emissions from the EUT were measured continuously at every azimuth by rotating the turntable. The Receiving
   antenna high is varied from 1 m to 4 m high to find the maximum emission for each frequency. Emissions below 30MHz
   were measured with a loop antenna while emission above 30MHz were measured using a broadband E-field antenna.
5. Maximizing procedure was performed on the six (6) highest emissions to ensure EUT compliance is with all installation
   combinations. All data was recorded in the peak detection mode. Quasi-peak readings was performed only when an
   emission was found to be marginal (within -4 dB of specification limit), and are distinguished with a "QP" in the data
   table.
6. Each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. In
   order to find out the max. emission, the relative positions of this transmitter(EUT) was rotated through three orthogonal
   axes according to the requirements in Section 8 and 13 of ANSI C63.4:2014

Note:           (1) All Readings below 1GHz are Quasi-Peak, above are performed
                    with peak and/or average measurements as necessary.
                (2) “N/A” remark, if no specific emissions from the EUT are
                    recorded (ie: margin>20dB from the applicable limit) and
                    considered that’s already beyond the background noise floor.
                (3) Emission Level = Reading Level + Probe Factor + Cable Loss.
