3.0 EQUIPMENT UNDER TEST (EUT) DETAILS
3.1 EUT Description
The EUT is a transmitter for a prosthetic arm, Model DKLU-10521-652, manufactured by Mobius Bionics
LLC. The EUT was in good working condition during the tests, with no known defects. There are two
identical transmitters in the arm. The two transmitters are identified as MSP1 and MSP2 herein. The two
transmitters have the same electronics, with different antennas.
3.1.1 FCC Section 15.203 Antenna Requirements
The antenna is internal to the EUT and it is not readily available to be modified by the end user. Therefore,
it meets the 15.203 Requirements.
3.2 Related Submittals
The associated transceiver is operated under part 15.249. It is subject to the FCC requirements pursuant to
the Certification equipment authorization under Part 15 Subpart C, and is being submitted as FCC ID:
2AJ4M20260 and 2AJ4M20275.
4.0 TESTED SYSTEM DETAILS
4.1 Tested System Configuration
The system was configured for testing in a typical fashion. The EUT was placed on an 80-cm high,
nonconductive test stand. The testing was performed in conditions as close as possible to installed
conditions. Wiring was consistent with manufacturer's recommendations. The EUT was tested while
connected to its charger, since this is the worst-case configuration.
The identification for all equipment, plus descriptions of all cables used in the tested system, are:

A computer-controlled analyzer was used to perform the conducted emissions measurements. The
frequency range was divided into 500 subranges equally spaced on a logarithmic scale. The computer
recorded the peak of each subrange. This data was then plotted on a semi-log graph generated by the
computer. Adjusting the positions of the cables and orientation of the test system then maximizes the
highest emissions.
Mains Conducted emission measurements were performed using a 50 Ohm/50 uH Line Impedance
Stabilization Network (LISN) as the pick-up device. Measurements were repeated on both leads within the
power cord. If the EUT power cord exceeded 80 cm in length, the excess length of the power cord was
made into a 30 to 40 cm bundle near the center of the cord. The LISN was placed on the floor at the base
of the test platform and electrically bonded to the ground plane.

11.2 Radiated RF Emissions
Radiated emission measurements were performed with linearly polarized broadband antennas. The results
obtained with these antennas can be correlated with results obtained with a tuned dipole antenna. The
radiated emission measurements were performed with a spectrum analyzer. The bandwidth used from 150
kHz to 30 MHz is 9 or 10 kHz and the bandwidth from 30 MHz to 1000 MHz is 100 or 120 kHz. Above 1
GHz, a 1 MHz bandwidth is used. A 10 dB linearity check is performed prior to start of testing in order to
determine if an overload condition exists. A harmonic mixer was used from 18 to 25 GHz. Figure 4 herein
lists the details of the test equipment used during radiated emissions tests.
The EUT was rotated through three orthogonal axis as per 5.10.1 of ANSI C63.10 during the radiated tests.
Final radiated emissions measurements were performed inside of an anechoic chamber at a test distance of
3 meters. The anechoic chamber is designated as Chamber E. This Chamber meets the Site Attenuation
requirements of ANSI C63.4 and CISPR 16-1. Chamber E is located at 12 East Devonwood Ave.
Romeoville, Illinois EMI test lab.
The entire frequency range from 30 to 25,000 MHz was slowly scanned with particular attention paid to
those frequency ranges which appeared high. Measurements were performed using two antenna
polarizations, (vertical and horizontal). The worst case emissions were recorded. All measurements may
be performed using either the peak, average or quasi-peak detector functions. If the peak detector data
exceeds or is marginally close to the limits, the measurements are repeated using a quasi-peak detector or
average function as required by the specification for final determination of compliance.
The detected emission levels were maximized by rotating the EUT, adjusting the positions of all cables, and
by scanning the measurement antenna from 1 to 4 meters above the ground.

11.2.1 Field Strength Calculation
The field strength is calculated by adding the Antenna Factor and Cable Loss, and by subtracting the
Amplifier Gain from the measured reading. The basic equation is as follows:
FS = RA + AF + CF - AG + HPF + PKA
Where: FS = Field Strength
RA = Receiver Amplitude
AF = Antenna Factor
CF = Cable Attenuation Factor
AG = Amplifier Gain
PKA = Peak to Average Factor (This is only used for average measurements above 1 GHz)
The Peak to average factor is used when average measurements are required. It is calculated by the
highest duty cycle in percent over any 100mS transmission. The factor in dB is 20 * Log(Duty cycle/100).
Note: The actual FCC limits are in uV/m. The data in the results table coverted the limits to dBuV/m.
100 uV/m = 40.0 dBuV/m
150 uV/m = 43.5 dBuV/m
200 uV/m = 46.0 dBuV/m
500 uV/m = 54.0 dBuV/m
11.2.2 Duty Cycle
The Peak to average factor is calculated by the highest duty cycle in percent over any 100mS transmission.
The factor in dB is 20 * Log(Duty cycle/100).
MSP1: The transmitter operates for a maximum duration of 0.967x5 ms in any 100 ms interval for a 4.835%
maximum duty cycle. 20 Log*(4.835mSec/100mSec) = -26.3 dB Peak to average Correction factor.
MSP2: The transmitter operates for a maximum duration of 3.086x2 ms in any 100 ms interval for a 6.172%
maximum duty cycle. 20 Log*(6.172mSec/100mSec) = -24.2 dB Peak to average Correction factor.

11.3 Occupied Bandwidth Data
The occupied bandwidth of the RF output was measured using a spectrum analyzer. The bandwidth was
measured using the peak detector function and a narrow resolution bandwidth.
A broadband antenna was used to receive the modulated signal. The spectrum analyzer was set to the
MAX HOLD mode to record the worst case of the modulation. The spectrum analyzer display was digitized
and plotted. A limit was drawn on the plots based on the level of the modulated carrier. The plots of the
occupied bandwidth for the EUT are supplied on the following page.
