4 TEST METHODOLOGY
Both conducted and radiated testing were performed according to the procedures
document on TIA-603-E and FCC CFR 47, Part 27 Subpart L, KDB 971168 D01 Power
Meas License Digital Systems.
4.1 EUT CONFIGURATION
The EUT configuration for testing is installed on RF field strength measurement to meet
the Commissions requirement and operating in a manner that intends to maximize its
emission characteristics in a continuous normal application.
4.2 DESCRIPTION OF TEST MODES
The EUT (model: TREK-530) had been tested under operating condition.
EUT staying in continuous transmitting mode was programmed.
After verification, all tests carried out are with the worst-case test modes as shown below
except radiated spurious emission below 1GHz and power line conducted emissions
below 30MHz, which worst case was in normal link mode and receiving radiated spurious
emission above 1GHz, which worst case was in CH Mid mode only.
WCDMA Band IV:
Channel Low (CH1312), Channel Mid (CH1413) and Channel High (CH1513) were
chosen for full testing.

TEST PROCEDURE
1. The EUT was placed on a non-conductive rotating platform (0.8m for below 1G and
above 1G) in a semi-chamber. The radiated emission at the fundamental frequency was
measured at 3m and SA with RMS detector per section 5, KDB 971168 D01 Power Meas
License Digital Systems.
2. During the measurement, the call box parameters were set to get the maximum output
power of the EUT. The maximum emission was recorded from spectrum analyzer power
level (LVL) from 360 degrees rotation of turntable and the test antenna raised and lowered
over a range from 1m to 4m in both horizontally and vertically polarized orientations.
3. EIRP was measured method according to TIA/EIA-603-E. The EUT was replaced by the
substitution antenna at same location, and then record the maximum Analyzer reading
through raised and lowered the test antenna.

TEST PROCEDURE
The equipment under test was connected to an external AC or DC power supply and input
rated voltage. RF output was connected to a frequency counter or spectrum analyzer via
feed through attenuators. The EUT was placed inside the temperature chamber. Set the
spectrum analyzer RBW low enough to obtain the desired frequency resolution and
measure EUT 20oC operating frequency as reference frequency. Turn EUT off and set
the chamber temperature to –30oC. After the temperature stabilized for approximately 30
minutes recorded the frequency. Repeat step measure with 10oC increased per stage
until the highest temperature of +50oC reached.
