1.3 Test Methodology and Considerations

The EUT is capable of being powered from a coin cell battery, commercially available wall-wart
power supply, and the USB communication cable from a laptop. All modes of operation, including
all data rates, were evaluated and the data presented in this report represents the worst case
where applicable. The module was tested in a standalone condition on an evaluation board.

For radiated emissions, the EUT was evaluated in three orthogonal orientations. The worst-case
orientation was Z-orientation. The EUT was evaluated with the coin cell battery, wall-wart power
supply, and over USB from a representative laptop computer. The worst-case power mode was
the wall-wart power supply. See test setup photos for more information. The EUT was evaluated
with the highest gain antenna of each type. See the Theory of Operations for more information.

For AC power line conducted emissions, the EUT was evaluated with a commercially available
wall-wart power supply and over USB from a laptop computer. The worst-case power mode was
over USB from a laptop computer and was evaluated with the highest gain antenna of each type.

For RF Conducted Emissions, the EUT was evaluated using the external U.FL antenna connector
with suitable attenuation. The coupling cable and external attenuation were considered for all RF
conducted measurements.

2.3 Radiated Emissions Test Site Description

2.3.1 Semi-Anechoic Chamber Test Site

The Semi-Anechoic Chamber Test Site consists of a 20’ x 30’ x 18’ shielded enclosure. The
chamber is lined with Toyo Ferrite Grid Absorber, model number FFG-1000. The ferrite tile grid is
101 x 101 x 19mm thick and weighs approximately 550 grams. These tiles are mounted on steel
panels and installed directly on the inner walls of the chamber.

The turntable is 150cm in diameter and is located 160cm from the back wall of the chamber. The
chamber is grounded via 1 - 8’ copper ground rod, installed at the center of the back wall, it is
bound to the ground plane using 3/4" stainless steel braided cable.

The turntable is all steel, flush mounted table installed in an all steel frame. The table is remotely
operated from inside the control room located 25’ from the range. The turntable is electrically
bonded to the surrounding ground plane via steel fingers installed on the edge of the turn table.
The steel fingers make constant contact with the ground plane during operation.

Behind the turntable is a 3’ x 6’ x 4’ deep shielded pit used for support equipment if necessary.
The pit is equipped with 1 - 4” PVC chases from the turntable to the pit that allow for cabling to
the EUT if necessary. The underside of the turntable can be accessed from the pit so cables can
be supplied to the EUT from the pit.

2.3.2 Open Area Tests Site (OATS)

The open area test site consists of a 40’ x 66’ concrete pad covered with a perforated electro-
plated galvanized sheet metal. The perforations in the sheet metal are 1/8” holes that are
staggered every 3/16”. The individual sheets are placed to overlap each other by 1/4” and are
riveted together to provide a continuous seam. Rivets are spaced every 3” in a 3 x 20 meter
perimeter around the antenna mast and EUT area. Rivets in the remaining area are spaced as
necessary to properly secure the ground plane and maintain the electrical continuity.

The entire ground plane extends 12’ beyond the turntable edge and 16’ beyond the antenna mast
when set to a 10 meter measurement distance. The ground plane is grounded via 4 - 8’ copper
ground rods, each installed at a corner of the ground plane and bound to the ground plane using
3/4" stainless steel braided cable.

The turntable is an all aluminum 10’ flush mounted table installed in an all aluminum frame. The
table is remotely operated from inside the control room located 40’ from the range. The turntable
is electrically bonded to the surrounding ground plane via steel fingers installed on the edge of
the turn table. The steel fingers make constant contact with the ground plane during operation.

Adjacent to the turntable is a 7’ x 7’ square and 4’ deep concrete pit used for support equipment if
necessary. The pit is equipped with 5 - 4” PVC chases from the pit to the control room that allow
for cabling to the EUT if necessary. The underside of the turntable can be accessed from the pit
so cables can be supplied to the EUT from the pit. The pit is covered with 2 sheets of 1/4"
diamond style re-enforced steel sheets. The sheets are painted to match the perforated steel
ground plane; however the underside edges have been masked off to maintain the electrical
continuity of the ground plane. All reflecting objects are located outside of the ellipse defined in
ANSI C63.10.

Model(s): MBN52832 FCC ID: HSW2832 IC: 4492A-2832

7.5.2.4 Sample Calculation:
RC = RU + CFT

Where:
CFT = Total Correction Factor (AF+CA+AG)-DC (Average Measurements Only)
RU = Uncorrected Reading
RC = Corrected Level
AF = Antenna Factor
CA = Cable Attenuation
AG = Amplifier Gain
DC = Duty Cycle Correction Factor

Example Calculation: Peak – Internal Antenna

Corrected Level: 36.45 - 5.40 = 31.05dBuV/m
Margin: 74dBuV/m – 31.05dBuV/m = 42.9dB

Example Calculation: Average – Internal Antenna

Corrected Level: 35.86 - 5.40 - 33.47 = -3.01dBuV
Margin: 54dBuV – -3.01dBuV = 57.0dB
