4.0       EQUIPMENT UNDER TEST CONFIGURATION
          The WLL Base Station (BS) was configured with DC power supply modules and an external PC to program
          the EUT to output a PHS RF signal. The EUT with host external computer was configured for maximum
          signal gain and bandwidth. The EUT was operated in a manner representative of the typical usage of the
          equipment. During all testing, system components were manipulated within the confines of typical usage to
          maximize each emission.

6.0     TEST RESULTS
6.1     TEST TYPE: Radiated Emissions
6.1.1 TECHNICAL SPECIFICATION: 2.1053; 24.238(a)
6.1.2 TEST DATE(S):                8/21/00
6.1.3 MEASUREMENT PROCEDURES:
As required by §2.1053, field strength of spurious radiation measurements were made in accordance with the general
procedures of 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". Preliminary radiated emission measurements were
performed inside a shielded chamber with all digital signal generators on and terminated. The frequency list from the
preliminary measurements was used as a guide for making additional measurements on a 3 meter open area test site.
The outcome of these additional measurements is used to determine if formal substitution-method measurements are
deemed necessary. The unit was scanned over the frequency range of the system operation frequency to 19 GHz. The
Radiated Spurious Emissions Limit is obtained by the following:
Based on an output power (as measured at the output of the Amplifier) of 0.028 watts:

                                                     Po = 0.028 W




the radiated power level of all spurious emissions must be attenuated by at least 43 + 10log(Po) below Po, yielding:


                                  Po& [43 % 10Log(0.028)] ' & 13dBm

Mathematical calculations indicate that these measurements yield radiated power levels greater than 30 dB below the
-13 dBm limit for spurious emissions from the transmitter portion of the EUT calculated above. Therefore there was
no need to perform full substitution-method measurements for these detectable emissions.

6.4     TEST TYPE: Spurious Emissions at Antenna Terminals
6.4.1 TECHNICAL SPECIFICATION: 2.1051; 24.238(a)
6.4.2 TEST DATE(S):                8/16/00
6.4.3 MEASUREMENT PROCEDURES:
As required by §2.1051 of CFR 47, spurious emissions at antenna terminal measurements were made at the RF output
terminals using a 50 S attenuator and spectrum analyzer set for a 100 kHz bandwidth. This test was performed with
Digitally modulated carrier signals. The Digital signal generator was adjusted for continuous transmit on frequencies
in both the uplink and down-link frequency bands. The frequency spectrum was investigated from 9.0 KHz to 20 GHz.
For measuring emissions above 2 GHz, a high-pass filter was used to eliminate the fundamental transmit frequency
to prevent possible saturation effects on the front end of the spectrum analyzer.


6.4.4 RESULTS:
Equipment complies with Section 2.1051and 24.238(a)

6.5     TEST TYPE: Spurious Emissions at Antenna Terminals at Block Edges +/- 1 MHz
6.5.1 TECHNICAL SPECIFICATION: 2.1051; 24.238(b)
6.5.2 TEST DATE(S):                8/16/00
6.5.3 MEASUREMENT PROCEDURES:

As recommended in FCC Part 24, 1% of the 26dB bandwidth was chosen to measure the peak of any emission
inside the 1.0 MHz frequency band adjacent to each frequency block edge. All other frequencies were measured
using a 1.0 MHz RBW. The unit was exercised using signal types required by §2.1049.

6.5.4 Results:
Modulation products outside of this band are attenuated at least 43 + 10 Log (P) below the level of the modulated
carrier. A Plot of the spurious emissions at +/- 1 MHz around the transmit frequency, as measured at the antenna
port, appears on the following page.

6.6.2 TEST DATE(S):                  8/17/00
6.6.3 MEASUREMENT PROCEDURES:
As required by §2.1055(a)(1) of CFR 47, frequency tolerance measurements were made over the temperature
range of -30EC to +50EC. The frequency measurements were made using direct input to a spectrum analyzer.
Climatic control was accomplished using an environmental simulation chamber. The temperature was first
lowered to -30EC and then raised hourly in 10E increments. The unit remained in the chamber during temperature
transitions and during the measurement process.

Frequency tolerance of carrier signal: +/- 1 KHz for a temperature variation from - 30EC to + 50EC at normal
supply voltage.

* Under these temperature ranges, The modulation distortion of the EUT (BS) caused a
spreading of the intended signal which was manually/visually determined to deviate no
more than 1 KHz.
The spreading of the signal did not cause the EUT to generate emissions out of compliance
with block edge power requirements of 24.238.
Per specification, the operational temperature range is 0 to 45 degree Celsius.
