To avoid damage to the instrument, use the following guidelines to prevent electrostatic discharge to the instrument:
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.
Discharge any static voltage from all cables before connecting them to the instrument or device under test by momentarily
grounding the c
cable to the instrument.
A cable that is left unconnected on a bench can develop a large static charge.
Nothing capable of generating or holding a static charge should be allowed on the work station surface.

BERTScopePC software
The BSAITS125 is primarily intended to be connected to a system controlled by a B ERTScope analyzer. The BERTScope
er senses the presence of the BSAITS125 through the USB interface when you power on the instruments in the
analzy
system. The BSAITS125 is controlled by the BERTScope analyzer through menus in the S tress Combiner view.
The BSAITS125 can also be controlled by a PC running the BERTScope PC 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
ne of the other selections in the menu).

This section provides a brief overview of the Stress Combiner view. For additional information on the controls in the user
interface, refer to the online help topics.
The following table describes some of the features of the Stress Combiner view.
Table 8: Stress Combiner view features
Item Description
Click the ISI Setup to define the main setups for the BSAITS125 in the Stress
Combiner view, such as c hanging 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 combined 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 P rimary and Secondary Channels are
connected in series and the result is available at the Secondary Output connectors.

Item Description
Click the Secondary ISI to select the Secondary ISI channel. Select from among
five internal ISI channels or Pass Through to bypass the internal ISI channels. The
Secondary ISI runs from the Secondary Input connectors to the Secondary Output
connectors on the front panel.
Frequency Response graph
This graph shows the S-Parameter data (S21 magitude in dB) for the selected ISI
path over a frequency range of 10 MHz to 20 GHz.
When only the Primary ISI is selected, the plot shows only the S-Parameter
data for the primary ISI.
When the Secondary option is present, the plot shows both the primary and
secondary S-Parameter data.
When the Primary and Secondary are linked, the plot shows the combined
S-Parameter data (the sum of the S21 of the Primary and the S21 of the
Secondary)
When a variable loss is entered or a D PP is used as an additional source, the
plot shows the combined data.

Applications
Applications
The BSAITS125 is primarily intended to be used in a system with a BERTScope analyzer and other Tektronix instruments.
The following section describes high-level setups in the example shown in the following illustration. Refer to the individual
product manuals for other setup information.
5: Sample application connection diagram
Figure
Guidelines for connecting the instruments in the example are listed below:
Connect the USB interface cables from the rear panel of the BERTScope analyzer to the BSAITS125 and the DPP125C
ECM instruments. The USB interface cables provide the c ommunications between the instruments in the system.
The AFG3252 function generator provides the stress inputs to the CM CAL and CMI input connectors on the BSAITS125.
Use the 30-in flexible coaxial cables with the BNC-to-SMA adapters on the function generator.
In addition to providing the user interface information, the BERTScope analyzer provides the s ingle-ended stress input
from the SI OUT connector on the rear panel of the analyzer to the DMI input connector on the rear panel of the
BSAITS125.
Connect the Data Outputs from the DPP125C ECM to the Primary Inputs of the BSAITS125 with the Tektronix-supplied
matched-cable pair (3.5 mm connector to 3.5 mm connector, 0.5 m long). The DPP125C provides the input signals
for this setup.
Use the Tektronix-supplied phase-matched, semi-rigid coaxial cable pair to connect the Primary Output connectors
of the BSAITS125 to the Secondary Input connectors.
Connect the Secondary Output connectors of the BSAITS125 to the D UT with a m atched-cable pair.
