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.

2. Use Manual Deskew Manual

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

Prerun checklist
Do the following before you click Start to run a test. If this is the first time you are running a test on a setup, refer to the information in
Before you click start.
1. Make sure that all the required instruments are properly warmed up (approximately 20 minutes).
2. Perform Signal Path Compensation (SPC):
a. On the oscilloscope main menu, select the Utilities menu.
b. Select Instrument Calibration.

Setting up the test environment
3. Verify that the application is able to find the DUT. If it cannot, perform a search for connected instruments:
a. In PCIe, select the Setup panel and then click the Test Selection tab.
b. Select any test and then click Configure.
c. n the Configuration section, click Global Settings.
d. In the Instruments Detected section, click the drop-down arrow to the right of Real Time Scope and make sure that the
oscilloscope with the (GPIB8::1::INSTR) designation is in the list.

Search instruments connected to the application
Use the TekExpress Instrument Control Settings dialog box to search the instruments (resources) connected to the application. The
application uses TekVISA to discover the connected instruments.
Note: The instruments required for the test setup must be connected and detected by the application, before running the test.
To refresh the list of connected instruments:
1. Select Options > Instrument Control Settings.
2. In the Search Criteria section of the Instrument Control Settings dialog box, select the connection types of the instruments to
search. Instrument search is based on the VISA layer, but different connections determine the resource type, such as LAN, GPIB, and
USB. For example, if you choose LAN, the search will include all the instruments supported by the TekExpress that are communicating
over the LAN.
3. Click Refresh. The TekExpress application searches for the connected instruments.
Search status of the instruments connected to LAN
4. When the search is complete, a dialog box lists the instrument-related details based on the search criteria. For example, for the Search
Criteria as GPIB, the application displays all the GPIB instruments connected to the application.
