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 20ºC with a humidity of 30%.

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.
