Pollution Degree Description
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
Pollution Degree 2 (as defined in IEC61010-1). Note: Rated for indoor use only.

Introduction
Introduction
The Tektronix BERTScope BSA85C, BSA125C, BSA175C, and BSA260C Bit Error Ratio 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 Ratio 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 has the comprehensive set of tools you need to perform receiver compliance testing,
transmitter debug, and advanced analysis to 26 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 Fiber
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 DSA 8200 sampling scope with the appropriate reference receiver
module.

Operating Requirements
Place the instrument on a cart or bench. The instrument should rest on its bottom or rear feet. An optional
rack mounting kit is available. Observe the following clearance requirements and dimensions:
Top: 0 in (0 mm)
Left and right side: 3 in (76 mm)
Bottom: 0 in (0 mm) standing on feet, flip stands down
Rear: 0 in (0 mm) on rear feet
Width: 15.5 inches (394 mm)
Height: 8.7 inches (220 mm)
Before operating the instrument, verify the ambient temperature: +10° C to +40 °C (+41 °F to +113 °F)
Preventing ESD
CAUTION
Electrostatic discharge (ESD) is a concern when handling any electronic equipment. The instrument is designed
with robust ESD protection; however it is still possible that large discharges of static electricity directly into the
signal input may damage the instrument. To avoid damage to the instrument, use the following techniques to
prevent electrostatic discharge to the instrument.
1. Discharge the static voltage from your body by wearing a grounded antistatic wrist strap while
connecting and disconnecting cables and adapters. The instrument provides a front panel connection
for this purpose.
A direct electrostatic discharge can damage the instrument input. To learn how to avoid this
damage, read the following information.
2. A cable that is left unconnected on a bench can develop a large static charge. Discharge the static
voltage from all cables before connecting them to the instrument or device under test by momentarily
grounding the center conductor of the cable, or by connecting a 50 Ω termination to one end, prior to
attaching the cable to the instrument.

available at any time at the bottom of the screen.
Like many internet browsers, Forward and Back can also be useful to move between previously visited screens.
Self Test
The BERTScope Analyzer performs Self Test at startup. Make sure that the
self-test reports all tests passed. If not, contact Technical Support. Close the
Self Test Dialog Box.
Setting Up the Pattern Generator
To get started, the only essential action is to switch the Pattern Generator Outputs On. Press
‘Outputs On/Off’ at the top of the display.

Setting Up a Simple BER Measurement
Troubleshooting Information
If the instrument does not behave as described here, some common areas to look for are:
Does the Error Detector say “Unstable Clock”?
Check that the Pattern Generator has its clock outputs switched on (press ‘Outputs On/Off’).
Check that there is a good coax connection between the Generator Clock output (either + or –) and the
Error Detector Clock Input.
Check that the Pattern Generator clock still has the internal clock source selected, rather than external.
Check that the Clock Input termination is set to the same termination as the Generator’s clock output.
Does the Error Detector say “No Sync”?
Check that the Pattern Generator Data Outputs are switched on (press ‘Outputs On/Off’).
Check that the Pattern Generator is set to a simple PRBS pattern, and that the Detector is set to Auto-
Pattern to automatically recognize any PRBS pattern.
Check that the Error Detector Data Input termination is set to the same termination as the Generator output
setting.
Check that the Error Detector Data Input is set to Differential input.
