1.0 Executive Summary
1.1 References
MIL-STD-461F, “Requirements for the Control of Electromagnetic Interference
Characteristics of Equipment and Subsystems,” 10 December 2007.
1.2 Requirements
The M&A Technology TUFFnote computer and FSP Group FSP065-RAB AC/DC Adapter were
evaluated with respect to the following MIL-STD-461F requirements.
CE102 - Conducted Emissions, Power Leads, 10 kHz to 10 MHz
RE102 - Radiated Emissions, Electric Fields, 2 MHz to 18 GHz
1.3 Summary of Results.
The equipment complies with the CE102 limit.
Significant RE102 emissions that alone influence where the equipment can be operated are as
follows. The TUFFnote computer with AC/DC adapter exceeds the RE102 limit for small-body
fixed-wing aircraft (< 25 meters nose-to-tail) in the 14.5 to 19 MHz and at three frequencies
between 2.4 and 4.5 MHz under battery operation. With the AC/DC adapter, the same emissions
exceed the RE102 limit for large-body fixed-wing aircraft (> 25 meters nose-to-tail) from about
15.5 to 16.5 MHz. Using either power source, the equipment has significant RE102 emissions
above the helicopter limit in the UHF radio frequency band (225 to 400 MHz).
The equipment adequately meets emission requirements for certification for use on Air Force
large-body fixed-wing Air Force aircraft when connected to aircraft 115 Volt AC power and for
all Air Force fixed-wing aircraft under internal battery operation.
2.0 General
2.1 Item Description
The equipment under test was an M&A Technology TUFFnote computer and FSP Group
FSP065-RAB AC/DC Adapter. The equipment will be used during flight. The equipment is
shown below.
TUFFnote Computer
FSP065-RAB AC/DC Adapter
2.2 Modes of Operation
The TUFFnote was turned on with the Windows Desktop displayed. Complete data scans were
taken with the computer powered by the AC/DC adapter (120 Volts, 60 Hz). Additional
measurements were accomplished under battery operation where possibly improved results were
anticipated.
2.3 Facility
The measurements were performed in a 20 foot x 18 foot x 10 foot shielding room. The room is
treated with anechoic material in accordance with MIL-STD-461F requirements. For CE102 and
RE102, test instrumentation was located in a separate shielded control room.
2.4 Test Setups
The general test setup was as shown below.
General Setup
A standard test equipment item used during all testing was a Line Impedance Stabilization
Networks (LISNs) inserted in the power leads per MIL-STD-461F. The network has two
sections, one for the high side of the power and a second for the return side.

In accordance with MIL-STD-461F, system accuracy measurements are performed prior to
testing to ensure that the measurement system will produce accurate results. Test frequencies
and voltage levels that are injected at the power lead connections to the LISNs are shown below.
The injected level is 6 dB below the MIL-STD-461F limit and is calculated as a peak-to-peak
voltage measured on an oscilloscope.

The following scans are performed to verify the integrity of the measurement setup prior to
testing. A calibrated signal is applied at the EUT power connection at each LISN at a level that
is 6 dB below the MIL-STD-461 limit. The indicated level on the plot should be 6 dB +/- 3 dB
from the limit line.

The cable loss from the antenna to the measurement receiver as stored in the software is shown
below. The loss was measured using a signal source and power meter. A reference level was
first established on the power meter at each frequency. The entire cable was then inserted and
the power level again measured. The difference is the cable loss.

The following scans are performed to verify the integrity of the measurement setup prior to
testing. A calibrated signal is applied at the antenna connection that is equivalent to a level that
is 6 dB below the MIL-STD-461 limit. The indicated level on the plot should be 6 dB +/- 3 dB
from the limit line.
