Pollution Degree Descriptions A measure of the contaminates that could occur in the environment around and within a product.
Terminals on this product may have different installation (overvoltage) category designations. The
installation categories are:
CAT III Distribution-level mains (usually permanently connected). Equipment at this level is
typically in a fixed industrial location.
CAT II Local-level mains (wall sockets). Equipment at this level includes appliances, portable
tools, and similar products. Equipment is usually cord-connected.
CAT I Secondary (signal level) or battery operated circuits of electronic equipment.
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 pollution occurs. 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.
Pollution Degree Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor use only.

NOTE. The “sym1.mpg” transport stream file is supplied with every instrument
in the following directory: E:\Test Streams.
If this file has been deleted from the E:\ drive of the instrument, you will need to
copy the file from the MTS400 Series MPEG Test System Recovery CD-ROM
(Tektronix part number 063-3851-xx) to the E:\ drive of the instrument to be able
to perform these procedures. This CD-ROM is supplied as a standard accessory
with the MTS400 Series system.
Preparing the Instrument
Perform the following steps to prepare the instrument to be tested:
1. Make sure the dongle is securely installed on the parallel port.
2. Connect the keyboard and mouse to the appropriate side panel or rear panel
connectors.
3. Connect the power cord to the rear-panel power input connector.
4. Make the following cable connections on the instrument (see Figure 2−1):
H Connect the 75 BNC-to-BNC cable between the ASI/SMPTE In
connector and the ASI/SMPTE Out connector.
H Connect the DB25-to-DB25 cable between the DVB/SPI In connector
and the DVB/SPI Out connector.
5. Power on the MTS400 Series system by pushing the front panel ON/STBY
switch.
6. After the Windows XP desktop appears, launch the Windows Explorer from
the Start menu.
