1. INTRODUCTION

The XM Satellite Radio, Inc., XM2go Model X2G-100 was evaluated for
compliance to the FCC Class B requirements and the results apply only to the
specific items of equipment, configurations and procedures supplied to the Florida
Atlantic University EMI Research Lab by XM Satellite Radio, Inc., as reported in
this document.

2. OBJECTIVE

Test Specifications

This evaluation was performed to verify conformance of the XM Satellite Radio,
Inc., XM2go XM Satellite Radio receiver to U.S. Federal Communications
Commission (FCC) Code of Federal Regulations (CFR), Title 47 -
Telecommunication, Part 15 - Radio Frequency Devices,

   •   Section 15.107(a) Conducted limits, and
   •   Section 15.109(a) Radiated Class B Emission limits.

Modes of Operation Tested

Per ANSI C63.4 Section 11, Measurement of Information Technology Equipment
(ITE), the device under test was configured to be continuously receiving data from a
host PC via a USB connection.

The Minimum System Requirements of ANSI C63.4, Section 11.2, were met by
using a host PC (laptop computer), and an additional external peripheral device
which utilized the Serial Port of the laptop with continuous data traffic on the cable.

Host PC : Laptop Model Compaq nc6000, Serial # CNU41228G9
External Peripheral : Earthmate GPS Receiver, Model Delorme
EUT : XM2go Hardware ID : BCWRJQMB

   •   During FCC Part 15 Subpart B, Paragraph 15.107(a) conducted emissions
       tests, the EUT was configured with the EUT in the XM2go home cradle with
       the XM Home AC adaptor.
   •   During FCC Part 15 Subpart B, Paragraph 15.109(a), radiated emissions, the
       EUT was configured and tested in two different operating modes:
           o In a XM2go home cradle powered by a 5V AC wall adapter.
           o In Portable Mode, under battery power.

3. CONCLUSION

The XM Satellite Radio, Inc., XM2go Model X2G-100, met the FCC Class B
conducted and radiated emission requirements as a PC Peripheral Device as
described in the following report.

  4.2 GENERAL TEST PROCEDURES

  The measurement techniques identified in the measurement procedure of ANSI
  C63.4-2003 "American National Standard of Measurement of Radio-Noise
  Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9
  kHz to 40 GHz" were followed as close as practical during this evaluation. Complete
  details and specific procedures used are discussed in the respective test result
  sections.

4.3 CONDUCTED EMISSIONS – Section 15.107(a)

4.3.1 Test Setup – Conducted Emissions

The XM Satellite Radio, Inc., XM2go50 Model X2G-100B; was powered by a I.T.I
 Power Supply Model No. SMPS5V2A-XMRT. The 120VAC/ DC 5V switching
power supply was then installed in the FAU EMI Research facilities conducted
emissions shielded enclosure on a wooden test table 80 centimeters above the ground
plane floor and 40 centimeters from the rear wall. The I.T.E Power Supply was then
plugged into an EMCO Model No.3825/2R Serial No. 1095, 50 Ω, 50 µH Line
Impedance Stabilization Network (LISN).

Conducted power line emissions were measured on both the phase and neutral lines
with reference to earth ground, over the specified 150 kHz to 30 MHz range on a
Hewlett Packard HP 8566B Spectrum Analyzer operated in the peak detection mode
with a bandwidth of 9 kHz obtained through the HP 85650A Quasi Peak Adapter and
in conjunction with HP85685A preselector. Photograph 1 and 2 depict the
conducted setup.

                                                                                5


          4.3.2 Test Data – Conducted Emissions

          The EUT was tested for the peak-detected emissions on phase and neutral lines while
          the XM2go50 unit was receiving data over the USB link connected to the host PC.

4.4 RADIATED EMISSIONS – Section 15.109(a)

4.4.1 General Test Setup – Radiated Emissions

The XM Satellite Radio, Inc., XM2go Model X2G-100 was set up on a wooden table
80 centimeters above the ground plane turntable of the FCC listed Semi-Anechoic
test site.

An EMCO 3104 Broadband Biconical antenna was installed on an EMCO
pneumatically controlled Antenna Mast at a distance of 3 meters from the system.
The 30 to 200 MHz frequency range was automatically scanned on the HP 8566B
Spectrum Analyzer operated in the peak detector mode with a bandwidth of 120 kHz
obtained through the HP 85650A Quasi Peak Adapter. It should be noted that the
RES BW and VBW of the spectrum analyzer must be set to 1 MHz for the Quasi
Peak Adaptor to provide 120 kHz bandwidth correctly. Hence, in the figures RES
BW and VBW are still indicated as 1 MHz. The turntable was incrementally rotated
through 360 degrees and at the same time the receiving antenna was scanned in
height from 1 to 4 meters in both the horizontal and vertical polarizations. An
EMCO 3146 Log Periodic antenna was then installed and the above procedure was
repeated for the 200 to 1000 MHz ranges.

The FCC Class B limit lines have been corrected for the appropriate antenna factors,
cable loss, and amplifier gain based on the following equation:

E (dBµV/m) = SA reading (dBµV) + Antenna Factor (dB/m) + Cable Loss (dB) -
             Amp Gain (dB)

The EUT was tested in TWO configurations under Section 15.109(a)
   o Home Cradle with Speaker attached
   o Portable Mode under battery power
