TEST: CONDUCTED SPURIOUS EMISSIONS Manufacturer: ITRONIX, Corporation. Name: IX300 Tablet PC Model: IX300 with AirCard 775, (WAN), WM168b-Molex, (WLAN), & MUBTC2-TH, (Bluetooth) Setup: The equipment under test (EUT) was set up in accordance with the provisions of ANSI C63.4- 2001, Section 7, on a 1 X 1.5-meter non-conductive test table at our Edmonds, Washington facility. The tabletop is 80 cm above a 2.5 x 2-meter horizontal ground plane and 40 cm forward from a 2.25 X 2.4-meter vertical ground plane. The two ground planes are continuously grounded along the common seam. The two 50 ohm/ 50 uHy Line Impedance Stabilization Networks (LISN) are grounded to the horizontal ground plane. The EUT was placed in a typical operational arrangement following the 10-cm spacing as detailed in Section 6.2 and 11.2, and the power cord of the EUT plugged into the first LISN. The signal output of this LISN was fed to the Agilent E7405 EMC analyzer using a 9 kHz bandwidth, which served as the measuring instrument. The peripheral equipment, if any were powered from a separate LISN. Discussion: Measurements of the AC power line conducted spurious emissions were made with the ITRONIX IX300 inserted into the Desk Stand and set up in a representative system configuration. The Desk Stand is also the charging stand for the IX300, which can operate during the charging process. The frequency range from 150 kHz to 30 MHz was measured in detail. No modifications were made prior to the final compliance test. Preliminary measurements were made as described in Section 7.2.3. The EUT was set up as an operational system. A Microsoft keyboard and a Microsoft optical mouse were connected to the USB ports on the Desk Mount. Measurements were made for the AC power input to the AC adapter Model: LSE9802A2060, which was connected to the Desk Mount and in turn powering the IX300. Excess I/O cable lengths were draped .5 m straight down behind the equipment then back up to the device used to terminate the line. The system cables were carefully tuned during the preliminary measurements on all frequencies of significance endeavoring to maximize the emissions observed. The test setup photos in Exhibit 7 detail the cable and equipment configuration for this test. 4

The ITRONIX Desk Stand with the IX300 inserted, was turned on and fully operational while the batteries were charging. This unit was set up to transmit with all three transmitters active simultaneously during the measurements. During the preliminary measurements this IX300 was set to operate with simultaneously transmit on the first the low, then mid and finally the high channels respectively in multiple sets of measurements covering operational range of both transmitters. Note that no measurable change in the conducted emissions activity was observed when the transmitters were turned on or off or varied over the channel combinations listed below. All of the following channel combinations were investigated during the preliminary measurements: AC555 WLAN & Bluetooth Channel Frequency MHz Channel Frequency MHz 128 824.2 and 1 2402 190 836.6 and 40 2441 251 848.8 and 79 2480 512 1850.2 And 1 2412 661 1880.0 And 40 2437 810 1909.8 And 79 2462 Final measurements were made as described in Section 7.2.3 while the EUT was fully functional as it would be in worst case (all three transmitters on) normal operation. The equipment had only one basic mode of operation, that being charging active. The final measurements were made with the AC775 transmitter set to 1880 MHz and the WLAN and Bluetooth Intentional Radiators set at 2412 MHz. The following page shows the measured results of the EUT emission profile. The spectrum was observed from .15 to 30 MHz. The Class B average limits are: 56 to 46 dBuV from (0.15 to .5 MHz), 46 dBuV from (.5 to 5 MHz) and 50 dBuV from (5 to 30 MHz). The conducted emissions were measured with Quasi-peak and Average detectors during the testing. The emissions results are reported for line 1, the "hot" and line 2, the "neutral" conductors, each with respect to ground at the power terminal. Conclusion The ITRONIX, Corporation IX300 when charging in the Desk Stand, met the conducted emissions requirements for Class B digital devices under Title 47 CFR, Part 15.107(a), and for Intentional Radiators under Part 15.207(a). 5

TEST: FIELD STRENGTH OF RADIATED EMISSIONS Manufacturer: ITRONIX, Corporation. Name: IX300 Tablet PC Model: IX300 with AirCard 775, (WAN), WM168b-Molex, (WLAN), & MUBTC2-TH, (Bluetooth) Setup: The equipment under test (EUT) was configured and operated in accordance with the applicable provisions of ANSI C63.4-2001, Section 6 and 8. The EUT was placed on the 80 cm height, 1 X 1.5 m non-metallic turntable that sits above the 15 X 30 meter ground plane at Spectrum's Open Area Test Site. There was no power cord as the device was battery operated. The antennas (dipoles, bi-conical or log-periodic) were mounted on a tower spaced at a 3 meters distance, and arranged for adjustment in height (1-4 meters) and V/H orientation to maximize the emissions levels when combined with turntable rotation of the EUT. An Agilent E7405 EMC analyzer, using 120 kHz bandwidth and a HP 8447F OPT H64 Amplifier were used for the measuring instrumentation. Discussion: Measurements of the radiated spurious emissions were made with the ITRONIX IX300 inserted into the Desk Stand and set up in a representative system configuration. The Desk Stand is also the charging stand for the IX300, which can operate during the charging process. The frequency range from 30 to 1000 MHz was measured in detail. No modifications were made prior to the final compliance test. Preliminary measurements were made as described in Section 8.3.1.1. The EUT was set up as an operational system. A Microsoft keyboard and a Microsoft mouse were connected to the two USB ports on the Desk Stand. Excess I/O cable lengths were draped .5 m straight down behind the equipment then back up to the device used to terminate the line. The system cables were carefully tuned during the preliminary measurements on all frequencies of significance endeavoring to maximize the emissions observed. During the preliminary measurements the IX300 was set up at the OATS facility with the receive antenna in close proximity, about 1.0 meter distance. The IX300 was operated on the frequencies listed on the following page to identify measurable emission frequencies. The test setup photos in Exhibit 7 detail the exact cable and equipment configuration for this test. During the preliminary measurements this IX300 was set to operate with simultaneously transmit on the first the low, then mid and finally the high channels respectively in multiple sets of measurements covering operational range of both 8

transmitters. Note that no measurable change in the conducted emissions activity was observed when the transmitters were turned on or off or varied over the channel combinations listed below. All of the following channel combinations were investigated during the preliminary measurements: AC555 WLAN & Bluetooth Channel Frequency MHz Channel Frequency MHz 128 824.2 and 1 2402 190 836.6 and 40 2441 251 848.8 and 79 2480 512 1850.2 and 1 2412 661 1880.0 and 40 2437 810 1909.8 and 79 2462 Preliminary measurements were made while the system was investigated operating in the following modes: 1) IX300 operating digital device active only, no transmitters turned on. 2) IX300 operating with the Bluetooth transmitter on low, mid and hi channel. 3) IX300 operating with the AirCard 775 transmitting on the high mid and low channels in the Cellular and PCS bands. For the final measurements, the IX300 inserted in the ITRONIX Desk Stand, turned on and fully operational while the battery was charging. This unit was set up to transmit with all three transmitters active simultaneously during the measurements. The final OATS test configuration is shown in photographs included in this report. Final digital device measurements were made from 30 - 1000 MHz as specified in Section 8.3.1.2 and were made at three meters. Conclusion: The ITRONIX, Inc. IX300 when operated as discussed above meets the radiated emissions requirements for a receivers and Class B digital devices under Title 47 CFR, Parts 15.109(a) and 15.209(a). 9
