1 GENERAL INFORMATION

1.1      SCOPE

FCC Rules Part 15.231: Periodic operation in the band 40.66-40.70 MHz and above 70 MHz.

1.2      TEST FACILITY

The open area test site and conducted measurement facility used to collect the radiated data is located at 360 Herndon
Parkway, Suite 1400, Herndon, Virginia 20170. This site has been fully described in a report and approved by the
Federal Communications Commission to perform AC line conducted and radiated emissions testing (ANSI C63.4 1992).

2 TEST INFORMATION

2.1       TEST JUSTIFICATION

The EUT was tested in all three orthogonal planes in order to determine worst-case emissions. Radiated emission
measurements were made of the Fundamental and Spurious Emission levels.

2.2       EXERCISING THE EUT

The unit was tested in its typical configurations with an on time of 15 milliseconds over a period greater than 100
milliseconds (corresponding to a duty cycle factor of –16.5 dB). The unit was also tested in a continuous transmit mode
during testing. The EUT was investigated and tested in three orthogonal axes. The worst-case configuration is listed in
this report. The carrier was also checked to verify that information was being transmitted.

2.3       CONFORMITY WITH 15.231 (e)

In order to comply with the part 15.231(e) the unit must respect the following requirement for the silent period as shown
in plot 2-1.

      •    The device transmits only once per interrogation, and does not repeat a transmission for any interrogation.
           Devices are typically read once per month, but could be read as often as once per day.

      •    All transmissions are 15 msec. This time duration does not change, and is never greater than 15 msec.

      •    A transponder does not repeat packets at any time. It only sends one 15-msec packet reply for each
           interrogation.




                                                                                                    Page 5 of 30

3 RADIATED EMISSION - §15.231

3.1      RADIATED EMISSION LIMITS TEST PROCEDURE

The EUT was placed on a non-conductive table 0.8 meters above the ground plane. The table was centered on a
motorized turntable, which allows 360-degree rotation. For measurements of the fundamental signal and spurious/
harmonics, a measurement antenna was positioned at a distance of 3 meters as measured from the closest point of the
EUT.

3.2      DUTY CYCLE

The duty cycle correction factor is calculated by 20 log (15/100), with 20 dB being the maximum allowable duty
correction factor.

The duration of each transmission was found to be not greater than one second and the silent period between
transmissions was found to be at least 30 times the duration of the transmission, but in no case less than 10 seconds.




                                                                                                  Page 10 of 30

 3.3      RADIATED EMISSION LIMITS TEST DATA

 The fundamental was measured at 82.9dBuV/m in peak mode at 100% duty cycle. The 16 dB duty cycle correction
 factor was subtracted from the peak result to a corrected reading of 66.9 dBuV/m compared to a peak limit of 92.0
 dBuV/m per 15.35 and 15.231(e). The spurious and harmonics were corrected using the duty cycle factor and compared
 to the limit per 15.35 and 15.231(e)
