6 TekExpress CEI-VSR
Getting started
Map My TekExpress folder to drive X
The first time you run TekExpress CEI-VSR, it creates the following folders on the oscilloscope:
You need to map the shared My TekExpress folder as drive X: on the instrument running the CEI-VSR application. CEI-VSR
uses this shared folder to save session waveform files and for other application file transfer operations.
To map the My TekExpress folder on the instrument to be drive X:
1.Open Microsoft Windows Explorer.
2.From the Windows Explorer menu, click Computer and select Map network drive.
3.Select the Drive letter as X: (if there is any previous connection on X:, disconnect it first through Tools > Disconnect
Network drive menu of Windows Explorer. If you do not see the Tools menu, press the Alt key).
4.In the Folder field, enter the remote My TekExpress folder path (for example, \\192.158.97.65\ My
TekExpress).
To determine the IP address of the instrument where the My TekExpress folder exists, do the following:
1.On the instrument where the My TekExpress folder exists, click Start and select Run.
2.Enter cmd and press Enter.
3.At the command prompt, enter ipconfig and press Enter.
NOTE. The My TekExpress folder has the share name format
If the instrument is not connected to a domain, the share name format is
TekExpress
.
<domain><user ID>My TekExpress
<instrument name><user ID>My
.
NOTE. If the X: drive is mapped to any other shared folder, the application displays a warning message asking you to disconnect
the X: drive manually.

Application directories and their contents
TekExpress CEI-VSR application. The TekExpress CEI-VSR application files are installed at the following location:
Every time you launch TekExpress CEI-VSR, an Untitled Session folder is created in the CEI-VSR folder. The
Untitled Session folder is automatically deleted when you exit the CEI-VSR 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.

Operating basics
Run the application
To launch the TekExpress CEI-VSR application, do either of the following:
■
Select Application > CEI-VSR from the TekScope menu.
■
Double-click any saved TekExpress CEI-VSR session file (<file name>.TekX).
The oscilloscope opens the TekExpress CEI-VSR application:
When you first run the application after installation, the application checks for a file called Resources.xml located in the C:
\Users\<username>\My TekExpress\CEI-VSR folder. The Resources.xml file gets mapped to the X: drive when the
application launches. Session files are then stored inside the X:\CEI-VSR folder.
The Resources.xml file contains information about available network-connected instruments. If this file is not found, the
application runs an instrument discovery program to detect connected instruments before launching CEI-VSR.
NOTE. Do the steps in the Required My TekExpress folder settings topic before running tests with the CEI-VSR application for
the first time.
To keep the CEI-VSR application window on top, select Keep On Top from the CEI-VSR Options menu. If the application goes
behind the oscilloscope application, click Application > CEI-VSR to move the application to be in front.

Use the Clear button to clear all existing measurement results. Adding or deleting a
measurement, or changing a configuration parameter of an existing measurement, also clears

Operating basics
View connected instruments. Use the Instrument Control Settings dialog box to view or search for connected instruments
required for the tests. The application uses TekVISA to discover the connected instruments on all selected connection types.
NOTE. The correct instruments for the current test setup must be connected and recognized by CEI-VSR before running tests.
To refresh the list of connected instruments:
1.From the Options menu, select Instrument Control Settings.
2.In the Search Criteria section of the Instrument Control Settings dialog box, select the connection types of the instruments
for which 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 TekExpress that are
communicating over the LAN.
3.Click Refresh. TekExpress searches for connected instruments.
4.After searching, the dialog box lists the instrument-related details based on the search criteria you selected. For example, if
you selected LAN and GPIB as the search criteria, the application checks for the availability of instruments over LAN, then
GPIB, and then lists detected instruments on those connection types.
The details of the instruments are displayed in the Retrieved Instruments table. The time and date of instrument refresh is
displayed in the Last Updated field.
