Installation
Unpack the instrument and check that you have received all items listed as Standard Accessories. Check the Tektronix
Web site (www.tektronix.com) for the most current information. The instrument is intended to be operated in a controlled
laboratory environment.
The instrument is intended to operate on a bench top, in an instrument rack, or on top of another instrument such as the
Tektronix BERTScope Bit Error Rate Analyzer. There are four shock-absorbing feet located on the bottom of the instrument.
Operate the instrument only when positioned with the feet facing downward. Do not operate the instrument with the long axis
vertical, standing on its side, as this will block the path of air required for cooling.
CAUTION. Operating the instrument while it is standing on the side can damage and overheat the instrument. To avoid
damaging the instrument or to avoid overheating the instrument, do not block any of the air vents to allow proper cooling
during normal operation.
This instrument uses a low voltage soft power switch that activates the power supply. The primary power control circuitry is
always live whenever the power cable is connected to the mains. The instrument is fuse-protected to reduce the risk of
fire in the event of a power supply failure. Access to the power cable for disconnection from the mains in an emergency
may be required by local codes.

BERTScopePC software
The BSAITS125 is primarily intended to be connected to a system controlled by a BERTScope analyzer. The BERTScope
er senses the presence of the BSAITS125 through the USB interface w hen you power on the instruments in the
analzy
system. The BSA ITS125 is controlled by the BERTScope analyzer through menus in the Stress Combiner view.
The BSAITS125 can also be controlled by a PC running the BERTScope P C software. With the BERTScopePC software
installed on a Windows PC, and the stand-alone instrument connected to the PC via the standard USB interface, the
copePC software initiates installation of the appropriate driver and provides a user interface allowing control of all
BERTS
BSAITS125 functions. The user interface provided for each instrument is similar to the BERTScope analyzer.
Included in the installation is the BERTScope Remote Client application which provides for remote access to the
BERTScopePC application. This software must be installed on a PC running the Windows XP Professional operating system.
Insert the BERTScope PC disk in the disc drive of the PC and follow the on-screen instructions to install the software.
After the software is installed, start the software from the Start menu by selecting Start > BERTScope > BERTScope PC UI

Connector Description
10 Power switch Activates the power supply to provide power to the primary circuits in the
instrument. The switch lights green when power is turned on.
The primary power control circuitry is always live whenever the power cord
is connected to the instrument. To completely disconnect power from the
instrument, disconnect the power cord at the rear of the instrument after
properly powering off the instrument using the power switch.
NOTE. For PCIe, the DPP connects to the Primary Inputs and the DUT connects to the Primary Outputs because the
Combiner is before the ISI channel. For other standards, the Combiner is after the ISI c hannel where the DPP would connect
to the Primary or Secondary Outputs and the DUT would connect to the Primary Inputs.

Item Description
Click the ISI Setup to define the main setups for the BSAITS125 in the Stress
Combiner view, such as changing the reference frequency for the S-Parameter data
used to calculate losses on the ISI paths. Another selection enables the use of
variable ISI. Screen selections depend on the ISI Setup selections.
DPP ISI icon (information only). This icon displays when a DPP is connected to the
BSAITS125 inputs and Use DPP is enabled in the ISI Setup menu. The amount of
stress from the DPP displays under the icon.
Integrated Combiner icon (information only). This icon shows how signals
applied to the CM CAL, CMI, and DMI connectors are combined with the signals
applied to BSAITS125 front-panel inputs. The integrated combiner contributes a
frequency-independent loss of 1.5 dB; the loss is added to the primary ISI paths.
Click the Primary ISI to select the Primary ISI channel. Select from among
three internal ISI channels or Pass Through to bypass the internal ISI channels.
Front-panel connectors allow the selection of either of two differential ISI paths
(Path 1 or Path 2). The outputs of the Primary ISI are applied to the Primary output
connectors on the front panel.
This button is available when Enable Variable ISI is enabled in the ISI Setup menu.
When enabled the label of the Primary ISI button changes to Variable ISI. The
Variable ISI button allows you to enter a loss from –50 dB to 0 dB and software
selects the appropriate ISI paths. The loss that you enter can also be c ombined with
the loss from an attached DPP.
This button is available on BSAITS125 EXP instruments when you select Link
Primary Secondary from the ISI Setup menu. Use this selection when the Primary
Outputs are connected to the Secondary Inputs. Select the ISI channels from the
Primary ISI and Secondary ISI lists. The Primary and Secondary Channels are
