Shared My TekExpress folder is mapped to drive X: on the instrument running the 100GBASE-SR4 application. 100GBASESR4 uses this shared folder to save session waveform files and for other application file transfer operations.
Follow the below procedure 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.
TekExpress® 100GBASE-SR4 Printable Application Help 5
Getting started
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.
