Set application file permissions
Before you run tests for the first time, do the following:
- 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 thePCIe
folder. TheUntitled Session
folder is automatically deleted when you exit thePCIe
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.
-
- 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.Note:If the X: drive is mapped to any other shared folder, the application will display a warning message asking you to disconnect the X: drive manually. - Make sure that the My TekExpress folder (Drive X:) has read and write access:
- Right-click the folder and select Properties.
- Select the General tab and then click Advanced.
- In the Advanced Attributes dialog box, make sure that the option Encrypt contents to secure data is NOT selected (not checked).
- See the prerun checklist before you run a test.

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.

Prerequisite
Compensate the signal path
- Power on and wait for the instrument to complete its warm up period before continuing with this procedure.
- Disconnect any probes you have connected to the input channels.
- Set the instrument to Menu mode.
- Select Instrument Calibration from the Utilities menu.
- Note any instructions that appear in the resulting control window.
- Click Run SPC to begin the procedure. The procedure may take several minutes to complete.
- 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
![](/-/media/images/manuals/compliance-and-validation-software/deskewandattenuationsetuppng.jpg?h=399&w=456)
Deskew:
- 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.
- 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 1. Deskew popup window
- Use Manual Deskew Manual
- Use 6 dB Attenuation (Which is selected by default).
- Use Custom Attenuation.
Running tests
After selecting and configuring tests, review the Prerun checklist and then click Start to run the tests. While tests are running, you cannot access the Setup or Reports panels. To monitor the test progress, switch back and forth between the Status panel and the Results panel.
The application displays a report when the tests are complete. While the tests are running, other applications may display windows in the background. The TekScope application takes precedence over other applications, but you can switch to other applications by using the Alt + Tab key combination. To keep the TekExpress PCIe application on top, select Keep On Top from the TekExpress Options menu.

View test-related files
Files related to tests are stored in the
My TekExpress\PCI Express
folder. Each test setup in this folder has a test setup file and a test setup folder, both with the test setup name.
The test setup file is preceded by the TekExpress icon and usually has no visible file name extension.
Inside the test setup folder is another folder named for the DUT ID used in the test sessions. The default is DUT001.
Inside the DUT001 folder are the session folders and files. Each session also has a folder and file pair, both named for the test session using the naming convention (date)_(time). Each session file is stored outside its matching session folder:
![](/-/media/images/manuals/compliance-and-validation-software/pcie012png.jpg?h=183&w=160)
Each session folder contains image files of any plots generated from running the test session. If you selected to save all waveforms or ran tests using prerecorded waveform files, these are included here.
The first time you run a new, unsaved session, the session files are stored in the
Untitled Session
folder located at
..\My TekExpress\PCI Express
. When you name and save the session, the files are placed in a folder with the name that you specify. A copy of the test files stay in the Untitled Session folder until you run a new test or until you close the PCIe application.

De-embed using filter files
TekExpress PCIe provides an option to de-embed the signal path using filter files. You create the filter files. The filter files are .flt files composed of de-embed filter coefficients for a particular sampling rate. A filter file created for one sampling rate might not work for other sampling rates, so it is important to understand at what sampling rate the measurements are being performed.
Also, the de-embedding filters might differ based on the type of input. For example, if a single ended input is made using a matched SMA cable pair, a filter file for de-embedding a single SMA cable must be provided, since matched SMA cables mostly have similar s-parameters. So in this case, the same filter file is used to de-embed the SMA cable pair.
The maximum sampling rate provided on any channel combination on MSO/DPO/DSA70000/C/D/DX series oscilloscopes is 50 GS/s in realtime mode. The maximum sampling rate provided on Ch1-Ch3 and Ch2-Ch4 channel combinations on MSO/DPO/DSA70000C/D/DX/SX series oscilloscopes is 100 GS/s, provided only 2 channels are on at a given time.

How to run Base SRIS Tx Test Board tests
This document describes the procedure to run PCIe Base Spec Gen4/Gen5 SRIS Tx Test Board tests using TekExpress PCI Express.
Accessories required
- Gen4/Gen5 Base specification fixture
- SMA-SMP cables
- TCA-SMA 292D / TriMode probes
- AWG7002A or AWG7001A
Capture data signals at sampling rate of 100Gsps/200Gsps with 12.5 M record length. Ensure the PCIE_TX_Toggle_Patterns_v10.0.0.2.exe is installed on AWG-70K series and the recommended probes and real time oscilloscopes are used.
- In DUT panel, select Specification as BaseSpec and Device Type as SRIS Tx Test Board.
- If AWG70K is detected then the AWG Clock Setup check box will be enabled in the configuration panel. Click the Setup button next to AWG Clock Setup check box. This will bring up the SRIS configuration, with a selection to choose SSC on/Off.
- Based on the selections of the AWG Clock Setup check box, SSC on/Off selection and different combinations of AWG setup files will be loaded on the AWG. These combinations dictate if an external 100 MHz reference clock (with SSC on/Off) on Ch1 of the AWG will be transmitted. The following AWG files loaded as per configuration for Base specification (Device) and DUT Type SRIS Tx Test Board (Suite) for Gen4 and Gen5.
- Click Start and when the application prompts, power on the Gen4/Gen5 DUT. Ensure that the DUT transmits Gen4/Gen5 selected presets. Analysis will be done with SigTest.
