47 CFR Ch.1 (10-1-98 Edition)
FCC Part 15 Radio Frequency Devices
Subpart C Intentional Radiators
Section 15.231 Periodic operation in the band 40.66-40.70 Mhz
and above 70 Mhz.

2.1 Referenced Standards
ANSI C63.4-1992 Methods of Measurement of Radio-Noise Emissions from Low-
Voltage Electrical and Electronic Equipment in the Range of 9 Khz
to 40 Ghz.

2.2 Equipment Units Tested
The equipment tested was a 433.92 Mhz pulse modulated hand held battery powered
transmitter. This device is a hand held unit with no attached cables or protruding
antenna. The antenna is a permanent component and is part of the internal PC board
assembly. The unit is programmed to transmit a pulse modulated signal of 93 mS every
171 seconds once turned on.
This standard PC board 433.92 Mhz transmitter is a subassembly in various products.

Measurement cable losses, and antenna correction factors are included in the data
sheets. Average detection methods were used in the measurements. The Resolution
BW was set at 1 Mhz and the Video BW was set at 1 Hz with a Span of 0 Hz to perform
the correct average detected measurements.

2.5 Units of Measurement.

INTERNATIONAL

CERTIFICATION SERVICES, INC.

All measurements were taken in dBuV/m with the antenna located at 3 meters distance
from the EUT. Frequency measurements are recorded in Mhz. Input power to the
intentional radiator was not recorded---only the radiated emissions with the internal
transmitting antenna were recorded.

2.6 Location of Test Site
The open area test site (OATS) measurement facility used to collect the data was
International Certification Services, Inc. at 1100 Falcon Ave in Glencoe, MN 55336.
This site has been certified to be in spec of the normalized site attenuation per ANSI
C63.4-1992. See letter of compliance from FCC dated July 23, 1998. (FCC 31040/SIT
1300F2)

2.7 Measurement Procedures
The antenna was placed at a distance of 3 meters from the EUT. The EUT was set on
an insulating table in the OATS site and rotated through 360 degrees to determine the
worst case EUT orientation. The antenna was then positioned vertical and horizontal to
determine which antenna polarity orientation was worst case. Then certification data
th
was recorded at all the transmitter frequencies from the fundamental to the 10
harmonic at an antenna height variation of from 1-4 meters.

2.8 Reporting Measurement Data
See data sheets and plots in Attachment B.

2.9 Radiated Emissions Data
The frequency and amplitude of the tuned frequency of the EUT along with the
frequencies and amplitudes of the harmonics up to the 7th harmonic are reported in the
data sheets in Attachment B. This information is plotted against the limit of section
15.231 of FCC Part 15 subpart C. The polarization of the antenna for each
measurement is also recorded.

The Final Level, expressed in dBuV/m, is arrived at by taking the reading from the
spectrum analyzer (Level dBuV) and adding the antenna correction factor and cable
loss factor (Factor dB) and subtracting the preamp gain. This result then has the FCC
limit subtracted from it to provide the margin which gives the tabular data as shown in
the data sheets in Attachment B.

Example:

Frequency Level + Factor = Corr Data - FCC Limit = Margin
(MHz) (dBuV) + (dB) = (dBuV/m) - (dBuV/m) = (dB)
100.0 20.6 + 11.0 = 31.6 - 43.5 = -11.9

2.10 Operating Frequency Data for Intentional Radiators
All operating frequencies and harmonic frequencies and ambient temperature at which
all data was taken at is recorded in the data sheets in Attachment B.
INTERNATIONAL

CERTIFICATION SERVICES, INC.

2.11 Occupied Bandwidth Data for Intentional Radiators
The occupied BW data for the EUT is listed in the data sheets in Attachment B.

2.12 Summary of Results
The EUT passed the requirements of FCC Part 15 Subpart C, Section 15.231 with a
minimum passing margin of –22.13974 dBuV/m at the fundamental frequency of
433.95541 Mhz. No modifications were necessary to accomplish this compliance.

Each radiated emissions plot indicates the receiving antenna measurement distance in meters
and the emission amplitudes with respect to their applicable limits. The associated tabulation
for each radiated plot lists the emission frequency, the final emission level, and the margin

This indicates the worst case orientation of the EUT and antenna polarity is 90 degrees EUT
and vertical antenna polarity.

Testing was performed at this test configuration.

Transmit signal BW = 381 Khz. This is measured from ground floor to ground floor.

Transmit signal BW = 345 Khz at 80% down from peak carrier amplitude

INTERNATIONAL

Initial testing was performed in the anechoic shield room to determine if there were any other
spurious emissions other than the fundamental and its harmonics. No other emissions were
found.

Certification testing was performed at the OATS site with an antenna distance of 3 meters and
the EUT at 90 Degrees to the antenna.

The limit for section 15.231 is 12,500 uV/m with an Average Detector. This converted to dBuV
is 81.938 dBuV/m which is the limit shown in the next table.
