The signed original of this report, supplied to the client, represents the only “official” copy.
Retention of any additional copies (electronic or non-electronic media) is at Acme Testing’s
discretion to meet internal requirements only. The client has made the determination that EUT
Condition, Characterization, and Mode of Operation are representative of production units, and
meet the requirements of the specifications referenced herein.
Consistent with Industry practice, measurement and test equipment not directly involved in
obtaining measurement results but having an impact on measurements (such as cable loss,
antenna factors, etc.) are factored into the “Correction Factor” documented in certain test results.
Instrumentation employed for testing meets tolerances consistent with known Industry Standards
and Regulations.
The measurements contained in this report were made in accordance with the procedure ANSI
C63.4 - 1992 and all applicable Public Notices received prior to the date of testing. All
emissions from the device were found to be within the limits outlined in this report. Acme
Testing assumes responsibility only for the accuracy and completeness of this data as it pertains
to the sample tested.

4. Antenna requirement
4.1 Regulation
An intentional radiator shall be designed to ensure that no antenna other than that furnished by
the responsible party shall be used with the device. The use of a permanently attached antenna or
of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient
to comply with the provisions of Part 15C. The manufacturer may design the unit so that the user
can replace a broken antenna, but the use of a standard antenna jack or electrical connector is
prohibited. This requirement does not apply to carrier current devices or to devices operated
under the provisions of Sections 15.211, 15.213, 15.217, 15.219, or 15.221. Further, this
requirement does not apply to intentional radiators that must be professionally installed, such as
perimeter protection systems and some field disturbance sensors, or to other intentional radiators
which, in accordance with Section 15.31(d), must be measured at the installation site. However,
the installer shall be responsible for ensuring that the proper antenna is employed so that the
limits in this Part are not exceeded.
4.2 Result
The antenna consists 1/4 wave piece of 20 gauge wire. The antenna is contained inside the
transmitter housing and is not user accessible.

nonconductive table that is placed above the groundplane. Floor standing equipment is placed
directly on the groundplane. Any supplemental grounding mechanisms are connected, if
appropriate. The EUT is connected to its associated peripherals, with any excess I/O cabling
bundled to approximately 1 meter. The EUT is connected to a dedicated LISN and all peripherals
are connected to a second separate LISN circuit. The LISNs are bonded to the groundplane.

6. 20 dB Bandwidth and Channel Separation
6.1 Regulation
15.247(a1) Frequency hopping systems shall have hopping channel carrier frequencies separated
by a minimum of 25 kHz or the 20-dB bandwidth of the hopping channel, whichever is greater.
The system shall hop to channel frequencies that are selected at the system-hopping rate from a
pseudorandomly ordered list of hopping frequencies. Each frequency must be used equally on
the average by each transmitter. The system receivers shall have input bandwidths that match the
hopping channel bandwidths of their corresponding transmitters and shall shift frequencies in
synchronization with the transmitted signals.
6.2 Test Equipment
Spectrum Analyzer: Hewlett-Packard 8566B, Serial Number 2410A-00168, Calibrated:
31 December 1997, Calibration due Date: 31 December 1998
RF Preselector: Hewlett-Packard 85685A, Serial Number 2648A-00519, Calibrated:
31 December 1997, Calibration due Date: 31 December 1998
6.3 Test Procedures
The RF output of the EUT was connected to the RF input port of the RF preselector through a 20dB pad. The following measurements were made with a RBW = 100 kHz and VBW = 3KHz.
6.4 Test Results
The measured 20 dB bandwidth of the carrier frequency is 49 kHz. The transmitter has hopping
channel carrier frequencies separated by 400 kHz.
The transmitter generates a Reed-Solomon pseudo random frequency hop sequence of length 64
based on a pre-programmed seed.
The transmitter can be set to operate on any one of 256 frequency channels in the 902-928MHz
band. The frequencies are divided into four groups of 64 frequencies; each group using every
fourth available frequency. 63 out of 64 frequencies in a group are then used equally by the
spread spectrum transmitter in a pseudo random sequence. 63 different sequences are available
for use in each frequency group.

12.3 Test Procedures
For tabletop equipment, the EUT is placed on a 1 meter by 1.5 meters wide and 0.8 meter high
nonconductive table that sits on a flush mounted metal turntable. Floor standing equipment is
placed directly on the flush mounted metal turntable. The EUT is connected to its associated
peripherals with any excess I/O cabling bundled to approximately 1 meter.
Preview tests are performed to determine the “worst case” mode of operation. With the EUT
operating in “worst case” mode, emissions from the unit are maximized by adjusting the
polarization and height of the receive antenna and rotating the EUT on the turntable.
Manipulating the system cables also maximizes EUT emissions.

13. Continuous Data and Short Transmissions
13.1 Regulation
15.247(g) Frequency hopping spread spectrum systems are not required to employ all available
hopping channels during each transmission. However, the system, consisting of both the
transmitter and the receiver, must be designed to comply with all of the regulations in this section
should the transmitter be presented with a continuous data (or information) stream. In addition, a
system employing short transmission bursts must comply with the definition of a frequency
hopping system and must distribute its transmissions over the minimum number of hopping
channels specified in this section.
13.2 Test Results
When required to send continuous data, all frequencies of a sequence (63) are used one before
any re-use of frequencies occurs. When presented with a short burst, any one frequency is not reused until all frequencies (63) of sequence have been used. The sequence is not truncated and restarted.

14. Coordination of Frequency Hopping
14.1 Regulation
15.247(h) The incorporation of intelligence within a frequency hopping spread spectrum system
that permits the system to recognize other users within the spectrum band so that it individually
and independently chooses and adapts its hopsets to avoid hopping on occupied channels is
permitted. The coordination of frequency hopping systems in any other manner for the express
purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple
transmitters is not permitted.
14.2 Result
This system does not incorporate intelligence to avoid interfering carriers. It progresses linearly
through the hopping sequence.
