1MA236_0e Rohde & Schwarz Remote Operation of Windows Based T&M Instruments with Android Tablets 8
3.1.2.1 Installation for Windows XP T&M Instruments
1 Install the WLAN USB Adapter
Many WLAN USB adapters are appropriate. Rohde & Schwarz uses the LogiLink
WL0049A as example device. A driver for the WLAN USB adapter is required.
Proceed as follows:
A) The driver is taken from the .zip package provided together with this application
note.
1. Unzip the .zip package (e.g. "SupplementaryFiles.zip") and copy the "…Setup.exe"
file onto the running T&M instrument (e.g. into the folder "C:\Temp\").
2. Execute the .exe file.
3. Accept the License Agreement.
4. Select the "Install driver only" option.
5. Close the installer program after the installation has completed successfully.
6. Insert the WLAN USB adapter into an empty USB port of the T&M instrument. You
can use any of its USB ports.
If the driver file is not automatically found after plugging in the WLAN USB adapter, a
"Files Needed" window is displayed (e.g. asking for the "rt2870.sys" file). Here, you can
manually enter the correct path for driver files: "C:\windows\system32\DRVSTORE\...\".

B) The T&M instrument has a CD/DVD drive and the driver is available on CD/DVD as
supplement of the WLAN USB adapter.
1. Insert the WLAN USB adapter into an empty USB port of the running T&M instru-
ment.
Windows detects that new hardware has been added and starts the "Found New
Hardware" dialog. Click on "Cancel".
2. Install the driver for the WLAN USB adapter from the CD/DVD according to the
instructions of the vendor of the adapter (insert the CD, after start of the driver in-
stallation (e.g. by auto-start) follow the instructions of the installation wizard, etc.).
2 Configure Auto-Start of the ad hoc WLAN Network
● Under “Control Panel/Administrative Tools/Computer Management”, select the
“Services and Applications/Services” view. Ensure that the “Wireless Zero Configu-
ration” service status is “Started” and that its "Startup Type" is “Automatic”.
