Appendix A. Test
Methods
A.1 Background Light and
Electromagnetic Field
There are four ambient
interference conditions in which
the receiver is to operate
correctly. The conditions are to
be applied separately:
1. Electromagnetic field: 3 V/m
maximum (please refer to
IEC 801-3, severity level 3 for
details).
2. Sunlight: 10 kilolux maximum
at the optical port. This is
simulated with an IR source
having a peak wavelength
within the range 850 nm to
900 nm and a spectral width
less than 50 nm biased to
provide 490

(with no
modulation) at the optical
port. The light source faces the
optical port.
This simulates sunlight within
the IrDA spectral range. The
effect of longer wavelength
radiation is covered by the
incandescent condition.
3. Incandescent Lighting:
1000 lux maximum.
This is produced with general
service, tungsten-filament, gas-
filled, inside-frosted lamps in
the 60 Watt to 150 Watt range
to generate 1000 lux over the
horizontal surface on which
the equipment under test rests.
The light sources are above the
test area. The source is
expected to have a filament
temperature in the 2700 to
3050 degrees Kelvin range and
a spectral peak in the 850 nm
to 1050 nm range.
4. Fluorescent Lighting:
1000 lux maximum.
This is simulated with an IR
source having a peak
wavelength within the range
850 nm to 900 nm and a
spectral width of less than
50 nm biased and modulated
to provide an optical square
wave signal (0

peak amplitude with 10% to
90% rise and fall times less
than or equal to 100 ns) over
the horizontal surface on
which the equipment under
test rests. The light sources
are above the test area. The
frequency of the optical signal
is swept over the frequency
range from 20 kHz to 200 kHz.
Due to the variety of
fluorescent lamps and the
range of IR emissions, this
condition is not expected to
cover all circumstances. It will
provide a common floor for
IrDA operation.

1.0 Solder Pad, Mask and Metal Stencil
All IR transceivers operating under the recommended drive conditions are classified as
CENELEC EN60825-1 Accessible Emission Limit (AEL) Class 1. This standard is in effect in
Europe as of January 1, 1997. AEL Class 1 LED devices are considered eye safe. Please see
Application Note 1094 for more information.
