Test Methods
Background Light and
Electromagnetic Field
There are four ambient interfer-
ence conditions in which the
receiver is to operate correctly.
The conditions are to be applied
separately:
1. Electromagnetic Field:
2. Sunlight:
3. Incandescent Lighting: 1000

to IEC 801-3, severity level 3
for details).
10 kilolux maximum at the
optical port. This is simulated
with an IR source having a
peak wavelength within the
range of 850 nm to 900 nm
and a spectral width of less
than 50 nm biased to provide

light source faces the optical
port.
This simulates sunlight within
the IrDA spectral range. The

radiation is covered by the
incandescent condition.

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 Kelvin range and a
spectral peak in the 850 to
1050 nm range.

simulated with an IR source

within the range of 850 nm to
900 nm and a spectral width of
less than 50 nm biased and

over the horizontal surface on
which the equipment under
test rests. The light sources are
above the test area. The fre-
quency of the optical signal is
swept over the frequency
range from 20 kHz to 200 kHz.
Due to the variety of fluores-
cent lamps and the range of IR
emissions, this condition is not
expected to cover all circum-
stances. It will provide a com-
mon floor for IrDA operation.
