Note: If TekExpress is installed on a Tektronix oscilloscope, TekExpress uses a virtual GPIB port to communicate with
oscilloscope applications. If external GPIB communication devices such as USB-GPIB-HS or equivalent are used for instrument
connectivity, make sure that the Talker Listener utility is enabled in the MSO oscilloscope GPIB menu. For ease of use, connect to
an external (secondary) monitor.

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.
All listed tests are required for compliance testing.

Search instruments connected to the application
About setting up tests
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.
The instruments required for the test setup must be connected and detected by the application, before running the test.
Note:
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.

About setting up tests
Before you click Start
Before you click start
Before you run tests for the first time, do the following:
1. Understand where your test files are stored on the instrument.
2. Map my TekExpress folder as X: (X drive) on all instruments used in test setup running Microsoft Windows Operating System.
The My TekExpress folder has the shared name format <domain><user ID>My TekExpress. Or, if the instrument
is not connected to a domain, then the shared name format is <instrument name><user ID>My TekExpress. This
shared folder is used to save the test session files and is used during any 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 has read and write access and that the contents are not set to be encrypted:
a. Right-click the My TekExpress 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.
4. Review the pre-run checklist before you run a test.

Starting the application
To start the TekExpress C-PHY, select Analyze > TekExpress C-PHY from the oscilloscope menu bar.
Starting the application
During start, a "My TekExpress" folder is created in the Documents folder of the current user and gets mapped to "X" drive. When the
application is closed properly, the "X" drive gets unmapped. Session files are then stored inside the X:\C-PHY folder. If this file is not
found, the application runs an instrument discovery program to detect connected instruments before starting TekExpress C-PHY.
To keep the TekExpress C-PHY application on top of any application, select Keep On Top from the options menu. If the application goes
behind the oscilloscope application, select Analyze > TekExpress C-PHY to bring the application to the front.
