TEST PROCEDURE

GENERAL: This report shall NOT be reproduced except in full without the
written approval of Thrulab & Engineering.

RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-
1992 using a HEWLETT PACKARD spectrum analyzer with a preselector. The
bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed.
The analyzer was calibrated in dB above a microvolt at the output of the antenna.
The resolution bandwidth was 100 kHz and the video bandwidth was 300 kHz. The
ambient temperature of the UUT was 26ºC with a humidity of 32%.

FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by
adding the meter reading of the spectrum analyzer (which is set to read in units
of dBuV) to the antenna correction factor supplied by the antenna manufacturer.
The antenna correction factors are stated in terms of dB. The gain of the
Preselector was accounted for
in the Spectrum Analyzer Meter Reading.

Example:
Freq (MHz) METER READING + ACF = FS
33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m

ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The unit
under test was placed on a table 80 cm high and with dimensions of 1m by 1.5m.
The table used for radiated measurements is capable of continuous rotation.

When an emission was found, the table was rotated to produce the maximum signal
strength. At this point, the antenna was raised and lowered from 1m to 4m. The
antenna was placed in both the horizontal and vertical planes.

The situation was similar for the conducted measurement except that the table
did not rotate. The EUT was setup as described in ANSIC63.4-1992 with the EUT
40 cm from the vertical ground wall.

Not Applicable, battery operated.

SAMPLE CALCULATION: FSdBuV/m = MR (dBuV) + ACFdB.

TEST PROCEDURE: The procedure used was ANSI STANDARD C63.4-1992. The spectrum
was scanned from 30 MHz to 1000 MHz. When an emission was found, the table was
rotated to produce the maximum signal strength. The antenna was placed in both
the horizontal and vertical planes and the worse case emissions were reported.
The UUT was tested in 3 orthogonal planes.
TEST RESULTS: THE UNIT DOES MEET THE FCC REQUIREMENTS.

NAME OF TEST: Occupied Bandwidth

RULES PART NO.: 15.227

REQUIREMENTS: The field strength of any emissions appearing between the band
edges and up to 10 kHz above and below the band edges shall be attenuated to the
general limits of 15.209.

1.705-30 MHz 69.54 dBuV/M MEASURED AT 3 METERS
30 - 88 MHz 40.0 dBuV/M
88 - 216 MHz 43.5 dBuV/M
216 - 960 MHz 46.0 dBuV/m
ABOVE 960 MHz 54.0 dBuV/m

THE GRAPH ON THE NEXT PAGE REPRESENTS THE EMISSIONS TAKEN FOR THE DEVICE.

METHOD OF MEASUREMENT: A small sample of the transmitter output was fed into
the spectrum analyzer and the attached plot was taken. The vertical scale is
set to 10 dB per division.

TEST RESULTS: The unit DOES meet the FCC requirements.
