ANNEX A: Detailed Test Results
A.1. Measurement Method
A.1.1. Conducted Measurements The measurement is made according to ANSI C63.10. 1). Connect the EUT to the test system correctly. 2). Set the EUT to the required work mode (Transmitter, receiver or transmitter & receiver). 3). Set the EUT to the required channel. 4). Set the EUT hopping mode (hopping or hopping off). 5). Set the spectrum analyzer to start measurement. 6). Record the values. Vector Signal Analyzer

A.1.2. Radiated Emission Measurements The measurement is made according to ANSI C63.10. The radiated emission test is performed in semi-anechoic chamber. The distance from the EUT to the reference point of measurement antenna is 3m. The test is carried out on both vertical and horizontal polarization and only maximization result of both polarizations is kept. During the test, the turntable is rotated 360° and the measurement antenna is moved from 1m to 4m to get the maximization result. In the case of radiated emission, the used settings are as follows, Sweep frequency from 30 MHz to 1GHz, RBW = 100 kHz, VBW = 300 kHz; Sweep frequency from 1 GHz to 26GHz, RBW = 1MHz, VBW = 1MHz;

Method of Measurement: See ANSI C63.10-clause 6.10.4
Connect the spectrum analyzer to the EUT using an appropriate RF cable connected to the EUT output. Configure the spectrum analyzer settings as described below. a) Set Span = 8MHz b) Sweep Time: Auto c) Set the RBW= 100 kHz c) Set the VBW= 300 kHz d) Detector: Peak e) Trace: Max hold Observe the stored trace and measure the amplitude delta between the peak of the fundamental and the peak of the band-edge emission. This is not an absolute field strength measurement; it is only a relative measurement to determine the amount by which the emission drops at the band edge relative to the highest fundamental emission level.

Method of Measurement: See ANSI C63.10-clause 11.11.2 and clause 11.11.3 Measurement Procedure Reference Level 1. Set the RBW = 100 kHz. 2. Set the VBW = 300 kHz. 3. Set the span to 1.5 times the DTS bandwidth. 4. Detector = peak. 5. Sweep time = auto couple. 6. Trace mode = max hold. 7. Allow trace to fully stabilize. 8. Use the peak marker function to determine the maximum PSD level. Next, determine the power in 100 kHz band segments outside of the authorized frequency band using the following measurement: Measurement Procedure – Unwanted Emissions 1. Set RBW = 100 kHz. 2. Set VBW = 300 kHz. 3. Set span to encompass the spectrum to be examined. 4. Detector = peak. 5. Trace Mode = max hold. 6. Sweep = auto couple. 7. Allow the trace to stabilize (this may take some time, depending on the extent of the span). Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding restricted frequency bands) is attenuated by at least the minimum requirements specified above.

Test Condition

The EUT was placed on a non-conductive table. The measurement antenna was placed at a

distance of 3 meters from the EUT. During the tests, the antenna height and the EUT azimuth

were varied in order to identify the maximum level of emissions from the EUT. This maximization

process was repeated with the EUT positioned in each of its three orthogonal orientations.

A.6. 6dB Bandwidth

Method of Measurement:

The measurement is made according to ANSI C63.10 clause 11.8.1 1.Set RBW = 100 kHz. 2. Set the video bandwidth (VBW) = 300 kHz. 3. Detector = Peak. 4. Trace mode = max hold. 5. Sweep = auto couple. 6. Allow the trace to stabilize. 7. Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the maximum level measured in the fundamental emission.

Measurement Limit: Standard

Method of Measurement: The measurement is made according to ANSI C63.10 clause 11.10.2

1. Set the RBW = 3 kHz. 2. Set the VBW = 10 kHz. 3. Set the span to 2 times the DTS bandwidth. 4. Detector = peak. 5. Sweep time = auto couple. 6. Trace mode = max hold. 7. Allow trace to fully stabilize. 8. Use the peak marker function to determine the maximum amplitude level within the RBW.

A.8. AC Powerline Conducted Emission

Method of Measurement: See ANSI C63.10-clause 6.2

1. the one EUT cable configuration and arrangement and mode of operation that produced the emission with the highest amplitude relative to the limit is selected for the final measurement, while applying the appropriate modulating signal to the EUT. 2. If the EUT is relocated from an exploratory test site to a final test site, the highest emissions shall be remaximized at the final test location before final ac power-line conducted emission measurements are performed. 3. The final test on all current-carrying conductors of all of the power cords to the equipment that comprises the EUT (but not the cords associated with other non-EUT equipment in the system) is then performed for the full frequency range for which the EUT is being tested for compliance without further variation of the EUT arrangement, cable positions, or EUT mode of operation. 4. If the EUT is comprised of equipment units that have their own separate ac power connections, e.g., floor-standing equipment with independent power cords for each shelf that are able to connect directly to the ac power network, each current-carrying conductor of one unit is measured while the other units are connected to a second (or more) LISN(s). All units shall be separately measured. If a power strip is provided by the manufacturer, to supply all of the units making up the EUT, only the conductors in the power cord of the power strip shall be measured. 5. If the EUT uses a detachable antenna, these measurements shall be made with a suitable dummy load connected to the antenna output terminals; otherwise, the tests shall be made with the antenna connected and, if adjustable, fully extended. When measuring the ac conducted emissions from a device that operates between 150 kHz and 30 MHz a non-detachable antenna may be replaced with a dummy load for the measurements within the fundamental emission band of the transmitter, but only for those measurements.36 Record the six highest EUT emissions relative to the limit of each of the current-carrying conductors of the power cords of the equipment that comprises the EUT over the frequency range specified by the procuring or regulatory agency. Diagram or photograph the test setup that was used. See Clause 8 for full reporting requirements.
