ENGINEERING TEST REPORT NO. 23566 Voluntary Laboratory Accreditation Program (NVLAP). NVLAP Lab Code: 100278—0 . 1.6 LABORATORY CONDITIONS: The temperature at the time of the test was 22°C and the relative humidity was 22%. 2 .0 TEST ITEM SETUP AND OPERATION: A block diagram of the test item setup is included as Fiqgure 1. 2.1 POWER INPUT: The test item received 9VDC power from an internal battery. 2 .2 GROUNDING: Since the test item was powered with a 9VDC battery, it was ungrounded during the tests. 2.3 PERIPHERAL EQUIPMENT: There was no peripheral equipment submitted with the test item. 2.4 INTERCONNECT CABLES: There were no interconnect cables submitted with the test item. 2.5 OPERATIONAL MODE: For all tests, the test item was energized and placed on a 80cmn high non—conductive stand. For all tests, the test item‘s transmit button was helad down thereby setting the unit to transmit continucusly. The transnmitting mechanism automatically deactivated when released. The battery voltage was periodically checked to ensure proper operation at maximum level. For test purposes, the test item was modified to transnit at 300MHz, 310MHz and 390MHz at the same time. In normal usage, only one of the selected frequencies is used at any tine. 3.0 TEST EQUIPMENT: 3.1 TEST EQUIPMXENT LIST: A list of the test equipment used can be found on Table I. All equipment was calibrated per the instruction manuals supplied by the manufacturer. The fundamental, harmonics and spurious emissions were measured Page 5s of26_

ENCGINEERING TEST REPORT NO. 235665 with a spectrum aralyzer. The spectrum analyzer peak detected readings were converted to average readings using a duty cycle factor. All measurements were taken with the resolution and video bandwidth of the measuring instrument adjusted to 100kHz below 1CGHz and 1MXz above 1GH2z . 3.2 CALIBRATION TRACEABILITY: Test equipment is maintained and calibrated on a reqular basis. All calibrations are traceable to the National Institute of Standards and Technology (NIST). 3.3 MEASUREMENT UNCERTAINTY: All nmneasurements are an estimate of their true value. The measurement uncertainty characterizes, with a specified confidence level, the spread of values which may be possible for a given measurement systen. The measurement uncertainty budgets were based on quidelines in "ISO Guide to the Expression of Uncertainty in Measurements" and NAMAS NIS&1 ‘"The Treatment of Uncertainty in EMC Measurements". The measurement uncertainty for these tests is presented below: conducted Emission Measurements : Combined Standard Uncertainty 1 .07 —1 .07 Expanded Uncertainty (95% confidence} 2 .1 —2 .1 Radiated Emission Measurements: Ccombined Standard Uncertainty 2 .26 —2 .18 Expanded Uncertainty (95% confidence} 4 .5 —4 . 4 4.,.0 REQUIREMENTS, PROCEDURES AND RESULTS: 4.1 POWERLINE CONDUCTED EMISSIONGS: 4.1.1 REQUEIREMENTS: All radio frequency voltages on the power lines of an intentional radiator shall be below 250uV (quasi— peak) over the frequency range from 0.45MHz to 30OMHz. It is also to be noted that if emitted levels in the peak detector function do not exceed the above linits, the test item does meet the intent of these requirements. page 6 __of2 6 _

ENGINEERING TEST REPORT NO. 23566 Since the test item was powered by internal batteries, no conducteqd emissions tests were performed. 4.2 DUTY CYCLE FACTOR MEASUREMENTS: 4.2.2 PROCEDURES: The duty cycle factor is used to convert peak detected readings to average readings. This factor is computed from the time domain trace of the pulse modulation signal. wWith the transmitter set up to transmit for maximum pulse density, the time domain trace is Aisplayed on the spectrum analyzer. This trace is obtained by tuning center frequency to the transmitter frequency and then setting a zero span width with 1O0msec/div. The amplitude setting are adjusted so that the on/off transitions clear the 4th division from the bottom of the display. The markers are set at beginning and end of a word period. If the word period exceeds 100 msec the word period is set to 100 msec. The on—time and off—time are then measured. The on—time is the total time the signal level exceeds the 4th division. Off—time is time under for the word period. The duty cycle is then computed as the (On—time/ word period) where the word period = (On—tinme + Off—time). 4,.2.3 RESULTS: Representative plots of the duty cycle at the transmit frequencies are shown on data pages 16 through 18. With the test item transmitting at 300MHz, the worst case duty cycle would be a 14.885 millisecond Word ON time during a 54.645 millisecond period. The duty cycle factor is 20*®*log(14.88§5/54.645)} = —11l.370B. wWith the test item transmitting at 310MHz, the worst case duty cycle would be a 15.285 millisecond Word ON time during a 54.515 millisecond period. The duty cycle factor is 20*log(15.285/54.516) = —11.06d4B. Page 7 of Zé

ENGINEERINCG TEST REPORT NO. 23556 With the test item transnitting at 390MHz, the worst case duty cycle would be a 8.492 millisecond Word ON time during a 54.446 millisecond pericod. The duty cycle factor is 20*log(8.492]/54.446) = —15.92dB. 4.3 RADIATED MEASUREMENTS: 4.3 .1 REQUIREMENTS: The test item must comply with the requirements of FCC "Code of Federal Regulations Title 47", Part 15, Subpart C, Section 15.205 et seq. Paragraph 15.231(b) has the following radiated emission limits: Fundamental Field Strength Frequency Field Intensity Harmonics and MHz uV /m @ 3 meters Spurious @3 meters 260 to 470 3,750 to 12,500* 375 to 1,250* * — Linear Interpolation For 300MHz, the limit at the fundamental is 5416.7u¥/m @ 3m and the limit on the harmonics is 541.7uV/m @ 3n. For 310MHKz, the limit at the fundamental is 58 33.3uV/m 8@ im and the limit on the harmonics is 5§83.3uV/m C 3m. For 3%0MHz, the linmit at the fundamental is 9166.7uV/m @ 3m and the limit on the harmonics is 916.7uV/m & 3n. In addition, emissions appearing in the Restricted Bands of Operation listed in paragraph 15.205(a) shall not exceed the general requirements shown in paragraph 15.209. 4.3.2 PROCEDURES: All tests were performed in a 32ft. x 20ft. x 18ft. hybrid ferrite—tile/anechoic absorber lined test chamber. The walls and ceiling of the shielded chamber are lined with ferrite tiles. Anechoic absorber material is installed over the ferrite tile. The floor of the chamber is used as the ground plane. Page _8 ofl é

ENGINEERING TEST REPORT NO. 23566 The chamber complies with ANSI C63.4 1992 for site attenuation. The shielded enclosure prevents emissions from other sources, such as radio and TV stations from interfering with the measurements. All powerlines and signal lines entering the enclosure pass through filters on the enclosure wall. The powerline filters prevent extraneous signals from entering the enclosure on these leads. Prelininary radiated emissions measurements were first performed using a peak detector and automatically plotted. The frequencies where significant emission levels were noted were then remeasured. wWith the broadband measuring antennas positioned at a 3 meter distance from the test item, the frequency range from 3OMHz to 4GHz was investigated using a peak detector function with the antennas set for vertical polarization. Final radiated emissions were performed on all significant broagdband and narrowband emissions found in the prelinmninary sweeps using the following methods: 1) Measurements were made using a peak detector and a dipole or double ridged waveguide antenna. 2) To ensure that maximum, or worst case, emission levels were measured, the following steps were taken: {a) The test item was rotated so that all of its sides were exposed to the receiving antenna. {b}) Since the measuring antenna is linearly polarized, both horizontal and vertical field components were measured . {(c}) The measuring antenna was raised and lowered from i to 4 nmneters for each antenna polarization to maximize the readings. {ad) The fundamental through the 10th harmonic of the transmit frequency were measured. 4.3.3 RESULTS: The prelinmninary plots, with the test iten transmitting at 300MHz, 310MHz and 390MHz are presented on data pages Page 9 of_ Z2 6

ENGINEERING TEST REPORT NO. 23566 19 and 20. The plots are presented for a reference only, and are not used to determine compliance. The final open area radiated levels, with the test iteom transmitting at 300MHz, is presented on data page 21. The final open area radiated levels, with the test item transmitting at 310MHz, is presented on data page 22. The final open area radiated levels, with the test item transnmnitting at 390MHz, is presented on data page 23. As can be seen from the data, all emissions measured from the test item were within the specification limits. The emissions level closet to the limit (worst case} occurred at 2100MHz. The emissions level at this frequency was 0.3dB within the limit. See data pages 21 through 23 for details., Photographs of the test confiquration which yielded the highest, or worst case, radiated emission levels are shown on Figures 2 and 3. 4.4 OCCUPIED BANDWIDTH MEASUREMENTS: 4.4.1 REQUIREMENTS: In accordance with paragraph 15.231(c), all emissions within 204B of the peak amplitude level of the center frequency are required to be within a band less than 0.25% of the center frequency wide. 4.4.2 PROCEDURES: The test itenm was placed on an 80cm high non—conductive stand. The unit was set to transmit continuously. With an antenna positioned nearby, occupied bandwidth emissions were displayed on the spectrum analyzer. The resolution bandwidth was set to 30 kHz and span was set to 2 MHz. The frequency spectrum near the fundamental was plotted. 4.4.3 RESULTS: The plot of the emissions near the 300MHz fundamental frequency are preserted on data page 24. The plot of the emissions near the 310MHz fundamental frequency are presented on data page 10 __of 26

ENGINEERING TEST REPORT NO. 23566 page 25. The plot of the emissions near the 390MHz fundamental frequency are presented on data page 26.
