Setting up the test environment
Set application file permissions
Before you run tests for the first time, do the following:
1. Understand where your test files are stored on the instrument.
After you install and start TekExpress PCIe, it creates the following folders on the oscilloscope:
• \My Documents\My TekExpress\PCI Express
• \My Documents\My TekExpress\PCI Express\Untitled Session
Every time you start TekExpress PCIe, an Untitled Session folder is created in the PCIe folder. The Untitled
Session folder is automatically deleted when you exit the PCIe application. To preserve your test session files, save the test setup
before exiting the TekExpress application.
CAUTION:
Do not modify any of the session files or folders because this may result in loss of data or corrupted session files. Each
session has multiple files associated with it. When you save a session, a .TekX file, and a folder named for the session that
contains associated files, is created on the oscilloscope X: drive.
2. Map the shared My TekExpress folder as X: (X drive) on the instruments used in test setups running Microsoft Windows Operating
System.
The My TekExpress folder has the share name format <domain><user ID>My TekExpress. Or, if the instrument is not
connected to a domain, the share name format is <instrument name><user ID>My TekExpress. This shared folder
is used to save the waveform files and is used during other file transfer operations.
If the X: drive is mapped to any other shared folder, the application will display a warning message asking you to
Note:
disconnect the X: drive manually.
3. Make sure that the My TekExpress folder (Drive X:) has read and write access:
a. Right-click the folder and select Properties.
b. Select the General tab and then click Advanced.
c. In the Advanced Attributes dialog box, make sure that the option Encrypt contents to secure data is NOT selected (not checked).

About setting up tests
Set up tests using the tabs in the Setup panel. Settings in the DUT tab use a top-down, left-to-right logic flow, so that any parameter that
affects or acts as a filter for other parameters appears either to the top of or to the left of the affected parameters.
Tests are saved when you save a test setup. To avoid overwriting test results, remember to assign a unique name to the test either before
running it or immediately after.

Setting up the test environment
Prerequisite
Compensate the signal path
Use the following procedure to compensate the internal signal acquisition path. Perform this procedure if the ambient temperature has
changed more than 5 °C (9 °F) since you performed the last signal path compensation. Perform the signal path compensation once a
week. Failure to do so may result in the instrument not meeting warranted performance levels.
1. Power on and wait for the instrument to complete its warm up period before continuing with this procedure.
2. Disconnect any probes you have connected to the input channels.
3. Set the instrument to Menu mode.
4. Select Instrument Calibration from the Utilities menu.
5. Note any instructions that appear in the resulting control window.
6. Click Run SPC to begin the procedure. The procedure may take several minutes to complete.
7. Verify that the Status changes to Compensated after the procedure is complete. If the Calibration Status field indicates anything other
than Compensated, see Signal Path Compensation Status for information on the readout and recommended action.
Note: When making measurements at vertical scale settings less than or equal to 5 mV, you should perform the signal path
compensation at least once a week. Failure to do so may result in the instrument not meeting warranted performance levels at
those volts/div settings.
Deskew and Attenuation
By clicking on the button opens up the Deskew and Attenuation Setup window which has the following options.
Deskew:
1. Use Automated Deskew (Which is selected by default) automated deskew works in the following way:
• By selecting the automated deskew, the application runs the deskew operation before acquiring the DUT signal.
• Deskew will be performed to remove the skew of the setup which is primarily the cable set and oscilloscope channel. Deskew
requires a low-frequency signal with a small rise/fall time. Both these requirements are fulfilled by the fast edge on the oscilloscope.
TekExpress® PCI Express Transmitter Compliance and Validation Software 25
Setting up the test environment
• During deskew the other end of the cable connected to the fixture/ISI board is connected to the fast edge. Fast edge has a skew of
less than 1 ps. If the +ve and -ve channels of fast edge are phase-matched, the user can ensure that the setup (cable+oscilloscope
channel) has a skew of less than 1 ps.
Figure 5: Deskew popup window
2. Use Manual Deskew Manual

Attenuation:
1. Use 6 dB Attenuation (Which is selected by default).
2. Use Custom Attenuation.

prerecorded waveform file for each test. See Set acquisition waveform source for prerecorded waveform files.
Set acquisition options
Select an Acquire Option to set the order in which waveforms are acquired and analyzed:
• Acquire All Waveforms Before Analysis: Acquire all waveforms required by tests before performing analysis. All required user
interventions (such as connecting to different lanes) are completed, and waveforms acquired, before the analysis is run. You can turn
off the DUT after the acquisitions are completed.
• Acquire Only – Do Not Analyze: Acquire all waveforms required by tests, and then stop (do not use waveforms to perform test
analysis). Use this setting for testing multiple DUTs once the test and application settings are correct. Acquire all required waveforms
and save the session for each DUT, and then recall the waveforms at a later point to analyze in Prerecorded mode.

Feature description
Link width
Link width determines the number of DUT signals. For example, x8 represents an eight lane DUT.
This works in conjunction with the signal polarity selected for each relay. For example, if the link width is x8, and:
• If the signal polarity is Positive, then the signal drop-down list will have selections from Lane0+ to Lane7+.
• If the signal polarity is Negative, then the signal drop-down list will have selections from Lane0- to Lane7-.
• If the signal polarity is Differential, then the signal drop-down list will have selections from Lane0 to Lane7.
Debug mode
Init Switch
Enter the Switch Address and click Init Switch to initialize the switch. This will synchronize the configuration of relay(s) in the application
with the relay(s) in the switch. Synchronization will only be successful for those relays that match the physical switch. Pass/Fail status is
displayed next to the button.
The factory default GPIB address for Keithley (GPIB0::7::INSTR) and Gigatronics (GPIB0::4::INSTR) is populated in the switch address
based on the configured vendor. You can enter the address in GPIB (GPIB0:X:INSTR) or TCPIP (TCPIP::IPADDR::INSTR) format.
Note: Relay configurations (number of relays, number of relay inputs, and name of relays) in the application should match the
physical switch, for successful synchronization.
Switch Self-Test
This will close and open all switch channels one-by-one. A selftest report (CSV) is generated at the end of the process. You cannot abort
this process.
Initialize the switch before performing the Switch Self-Test.
Note:
Reset Switch
Click Reset Switch to reset the switch. This will open all channels.
Init Scope
Enter the oscilloscope address in the Scope Address field and click Init Scope to initialize the oscilloscope. This will establish the
connection with the oscilloscope. The pass/fail status is displayed next to the button.
You can enter the address in GPIB (GPIB0:X:INSTR) or TCPIP (TCPIP::IPADDR::INSTR) format.
When the oscilloscope is initialized and de-embed settings are configured, closing a connection will apply the de-embed settings and then
close the connection.
The virtual GPIB address of the oscilloscope is GPIB8::1::INSTR.
Note:
Note: If oscilloscope fails to respond to the *IDN? query during initialization, then the connection attempt is considered a failure.

Cascade (Relay cascade)
This feature allows you to cascade the relay by connecting the common channel as an input signal for another relay.
To cascade, select Cascade in the relay and select the Relay and Input of the relay. Check that the selected relay signal displays the relay
name, specifying that the lane input signal is the output from that relay.

Tip: Switch Matrix application supports only single-level cascading of the relays. For example, if the Relay A output is cascaded to
Relay B, then the Relay B output cannot be cascaded.
