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 (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 W/cm
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
2
(with no modulation)
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 W/cm
minimum and 0.3 W/cm
amplitude with 10% to 90% rise
2
peak
2
12
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.
All HP IR transceivers are
classified as IEC 825-1
Accessible Emission Limit
(AEL) Class 1. AEL Class 1
LED devices are considered
eye safe. See Hewlett-Packard
Application Note 1094 for
more information.
