Class 1 – ground
A measure of the contaminants that could occur in the environment around
and within a product. Typically the internal environment inside a product is
considered to be the same as the external. Products should be used only in the
environment for which they are rated.
Pollution degree 1. No pollution or only dry, nonconductive pollution occurs.
Products in this category are generally encapsulated, hermetically sealed, or
located in clean rooms.
Pollution degree 2. Normally only dry, nonconductive pol
Occasionally a temporary conductivity that is caused by condensation must
be expected. This location is a typical office/home environment. Temporary
condensation occurs only when the product is out of service.
Pollution degree 3. Conductive pollution, or dry, nonconductive pollution
that becomes conductive due to condensation. These are sheltered locations
where neither temperature nor humidity is controlled. The area is protected
from direct sunshine, rain, or direct wind.

The OM4000 Coherent Lightwave Signal Analyzer is a 1550 nm (C- and
L-band) fiber-optic test system for visualization and measurement of complex
modulated signals, offering a complete solution to test both coherent and
direct-detected transmission systems. The OM4000 consists of a polarization- and
phase-diverse receiver and analysis software, enabling simultaneous measurement
of modulation formats important to advanced fiber communications, including
polarization-multiplexed (PM-) QPSK.
Key features
The OM4000 User Interface (OUI) software performs all calibration and
processing functions to enable real-time burst-mode constellation d iagram display,
eye-diagram display, Poincaré sphere, and bit-error detection.
A remote interlock for the laser, located on the rear of the unit, allows for remote
locking of laser output.
You can use the OM4000 instrument alo
OM2210, as well as supported real-time and equivalent-time oscilloscopes, for a
complete optical calibration and testing system.
Coherent lightwave signal analyzer architecture is compatible with both
real-time and equivalent-time oscilloscopes
Complete coherent signal analysis syste
QPSK, offset QPSK, QAM, differential BPSK/QPSK, and other advanced
modulation formats
Displays constellation diagrams, phase eye diagrams, Q-factor, Q-plot,
spectral plots, Poincaré sphere, signal vs. time, laser phase characteristics,
BER, with additional plots and analyses available through the MATLAB
interface
Measures polarization mode dispersion (PMD) of arbitrary order with most
polarization multiplexed signals

Initial product inspection
Do the following when you receive your instrument:
1. Inspect the shipping carton for external damage, whic h may indicate damage
to the instrument.
2. Remove the OM4000 instrument from the shipping carton and check that the
instrument has not been damaged in transit. Prior to shipment the instrument

is thoroughly i
nspected for mechanical defects. The exterior should not have
any scratches or impact marks.
NOTE. Save the shipping carton and packaging materials for instrument
repackaging in case shipment becomes necessary.
3. Verify that the shipping carton contains the basic instrument, the standard
accessories and any optional accessories that you ordered. (See Table 1.)
Contact your local Tektronix Field Office or representative if there is a problem
with your instrument or if your shipment is incomplete.
Environmental operating requirements
Check that the location of your installation has the proper operating environment.
(See Table 4.)
CAUTION. Damage to the instrument can occur if this instrument is powered on at
atures outside the specified ambient temperature range.

Do not obstruct the fan so that there is an adequate flow of cooling air to the
electronics compartment whenever the unit is operating. Leave space for cooling
y providing at least 2 inches (5.1 cm) at rear of instrument for benchtop use.
