Compliance information
Pollution degree descriptions
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 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 4. Pollution that generates persistent conductivity through conductive dust, rain, or snow. Typical
outdoor locations.
Pollution degree rating
Pollution degree 2 (as defined in IEC 61010-1). Rated for indoor, dry location use only.

Product description
Introduction
The Tektronix BERTScope BSA85C, BSA125C, BSA175C, BSA286CL Bit Error Rate Analyzers support serial data interfaces
from 1 Gb Ethernet to future 16x Fibre Channel and 4x 25.78 Gb/s 100 Gb Ethernet. BERTScope Bit Error Rate Analyzers
reduce your time to market by providing the most advanced and comprehensive combination of signal integrity analysis
and test tools available in a single instrument.
The BERTScope analyzer has the comprehensive set of tools you need to perform receiver compliance testing, transmitter
debug, and advanced analysis to 28.6 Gb/s. Featuring easy and flexible stress testing, physical layer analysis such as BER
Contour and Jitter measurements, and a Compliance Contour view for Mask Test, it represents a breakthrough in insight and
saved development time. Compliance Contour is a bridge between BER and mask testing, needed to meet the requirements
of standards such as OIF CEI, 40/100G Ethernet XLAUI/CAUI, and XFP/XFI.
NOTE. Optical transmitter compliance tests such as those required for optical 8x and 16x Fibre Channel, 10 GBASE-SR, LR,
and 40 and 100 GBASE-SR-4, LR-4, SR-10, and ER-4 are best addressed by the Tektronix DSA8300 sampling oscilloscope
with the appropriate reference receiver module.
Use the BERTScope analyzer together with the Tektronix BERTScope Clock Recovery instruments and the Digital
pre-emphasis processors to provide a complete testing solution.
Product description
