3 Software installation
The R&S VSE software can be installed and executed on any PC or directly on an
instrument which will be used as input for signal analysis. See the data sheet for information on which instruments the software can be installed on.
3.1 Installing required components
The following software components must be installed to run the R&S VSE successfully:
●
Microsoft .NET Framework 4.0
●
R&S License Server
●
VISA (Virtual Instrument Software Architecture)
The R&S License Server and Microsoft .NET Framework 4.0 are installed automatically during installation of the R&S VSE.
Software installation
Installing required components
VISA can be installed directly during installation of the R&S VSE, or manually, independently of the R&S VSE installation.
Installing the Microsoft .NET Framework
When you install the R&S VSE via the provided installation file (see Chapter 3.2,
"Installing and starting the R&S VSE software", on page 25), the installer automati-
cally checks whether the required Microsoft .NET Framework versions are available on
the PC. If not, version 3.5 is installed from the R&S VSE CD-ROM. An internet connection to the Microsoft website is established to download the Framework version 4.0
(due to the large file size). Thus, before attempting to install the R&S VSE software,
ensure that a strong internet connection is available from the PC, as downloading can
take some time. Alternatively, download the Framework 4.0 version from the internet
manually before you start the R&S VSE installer.
Installing VISA
It is also necessary to install VISA (Virtual Instrument Software Architecture) on the PC
to access instruments connected via IEEE or LAN bus.
It is recommended that you use the R&S VISA driver. The R&S VISA driver is supplied
with the R&S VSE installation file, and can be installed together with the R&S VSE
software (see Chapter 3.2, "Installing and starting the R&S VSE software",
on page 25).
Once the R&S VSE software is installed, a status icon in the status bar indicates
whether the VISA installation is available, see Table 6-1.

R&S®VSE
Software installation
Using the smart card reader
Demo mode
Without the use of the software license provided by a smart card reader, the software
starts in "Demo-Mode". In this case, all (installed) options and remote commands are
available. However, no instruments can be configured, no I/Q files and no measurement settings can be loaded or saved.
3.3 Using the smart card reader
The R&S VSE software requires a smart card containing the software license to be
connected to the PC when you are using the software. The R&S®FSPC license dongle
that contains the software license consists of a smart card and a USB dongle. The
smart card can be used in the supplied USB dongle or in a smart card reader. The
R&S®FSPC license dongle is available as a separate product and must be ordered in
addition to the software.
You can connect the smart card in two ways.
●
Connect the smart card in SIM format.
To connect the smart card in SIM format, use the USB smart card reader (dongle)
provided with the smart card.
●
Connect the smart card in its full format.
To connect the smart card in full format, an interface compatible to the card format
is required.
The following devices are able to read the smart card in full format.
– Smart card reader integrated in a keyboard, notebook, or in a desktop PC (e.g.
OMNIKEY)
– Smart card reader connected to the computer via serial bus or USB (e.g.
OMNIKEY)
– USB reader connected to a LAN-to-USB converter to distribute the license via
the network (e.g DIGI AnywhereUSB/2)
Licensing support
If you have any difficulties with the licensing system, support is only assured when you
are using the R&S®FSPC license dongle.
Using the R&S®FSPC USB smart card reader (dongle)
1.
The R&S®FSPC license dongle consists of a smart card in full format and a USB
smart card reader (dongle).

27User Manual 1176.8839.02 ─ 16
R&S®VSE
Software installation
Using a license server
The smart card reader is ready for use on any USB interface.
Drivers
When you connect the reader to the computer, MS Windows automatically installs the
necessary drivers. If not, you can install the drivers manually from the Internet site of
the manufacturer at http://support.identiv.com/utrust-token-standard/.
Problems during login due to smart card reader
When the smart card reader is connected, the operating system may falsely identify
the smart card as a medium to perform a login procedure on the PC. In this case, the
windows lock screen is displayed instead of a login window.
You can solve this issue by editing the "DisableCAD" ("Disable Ctrl-Alt-Del") registry
key in the system registry. This key is located at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
policies\system.
Administration rights
Security policies of your network environment might prevent you from editing the system registry or installing drivers. Contact your IT administration in that case.
To change the registry key
1. From the Windows "Start Menu", select the "Run" item.
(Windows 10: "Start > All applications > Windows System > Run")
2. Enter regedit in the dialog box to open the system registry.
3. Look for
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
policies\system.
4. Set the value of DisableCad to 0.
3.4 Using a license server
As an alternative to the R&S®FSPC license dongle, software licenses can now also be
provided by an R&S®License Server (for R&S VSE Enterprise Edition only). In this
case, all available licenses are stored on a specified server. When you need a particular application, you can obtain a license from the server. When you no longer need the
license, you return it to the server and it becomes available to other users again. These
licenses are also referred to as floating licenses, as opposed to permanently assigned
licenses.

R&S®VSE
Software installation
Using a license server
The R&S®License Server must be set up as described in the R&S®License Server Managing Floating Licenses - User Manual.
Two different kinds of floating licenses are available.
Common floating license
A common floating license enables you to use an option as long as you need it, but
requires a permanent connection to the license server.
The license is retrieved from the license server only when you open an application
channel. Only one license per option is retrieved, but the option can be used in multiple
channels. It is returned shortly after you close the (last) application channel. The
license is blocked for other users only while at least one application channel is in use.
If the connection to the license server is lost for longer than approximately 10 minutes,
the R&S VSE assumes no license is available and closes the application.
Occupied license
An occupied license is retrieved once from the license server and stored locally for up
to 7 days, depending on the selected time period. During the occupied period, the
license is blocked for other users. After this time, the license automatically expires and
becomes available on the license server again. During the occupied period, no further
access to the license server is required. The license cannot be returned or disabled
manually before it expires, but it can be extended.
When the license expires, you must retrieve a new license from the license server. If
the connection to the license server is not available or no more licenses are available,
the R&S VSE closes the application.
Setting up floating licenses
To use floating licenses, you must set up one or more floating license servers (see
"Setup Floating License Server" on page 168). The R&S VSE checks the configured
servers for available floating licenses when it starts up. Only options for which licenses
are found are available in the R&S VSE. After changing the floating license server configuration, you must restart both the local License Manager service and the R&S VSE
software.
When you first start the R&S VSE software after installation, if no license dongle or
floating license server is found, the software starts in demo mode.
In the software, you can disable, re-enable or occupy licenses from the server for individual applications. Note that all application-specific licenses for a particular application
are always enabled or disabled together, you cannot obtain individual sublicenses
(such as K100 without K102 for the LTE application).
The currently activated licenses are indicated in the "Versions + Options" dialog box in
the "Help" menu, see Chapter 9.4.1, "Licensing, versions and options", on page 166.

®
AWR®VSS
The Cadence AWR Visual System Simulator (VSS) allows you to simulate RF components in complete communication links. By integrating R&S®VSESIM-VSS into the simulator, you can extend the simulation to baseband signal analysis for various RF components. For example, you can use R&S WinIQSim2 to create encrypted waveform
files as input for Cadence®AWR®VSS. Then you can analyze the simulated processed
data using the R&S VSE functionality.
Figure 3-1: Typical integration scenario for R&S VSE and Cadence®AWR®VSS
Scope of functionality and restrictions
Using the simulator, the R&S VSE can only process input from encrypted waveform
files, as provided by the RS_SNK block in Cadence®AWR®VSS. It cannot analyze input
from an instrument, such as R&S FSW or R&S FSV3000. Otherwise,
Cadence®AWR®VSS provides the same analysis functionality as the R&S VSE Basic
Edition with all supported applications.
To integrate R&S VSE in Cadence®AWR®VSS
To integrate R&S VSE in Cadence®AWR®VSS, you must install additional .dll files to
Cadence®AWR®VSS via the common R&S VSE installation. Integration is only possible if the Cadence®AWR®VSS software is installed before you start the R&S VSE
installation. If necessary, repeat the R&S VSE installation for the Cadence®AWR®VSS
option after installing the Cadence®AWR®VSS software. The R&S WinIQSim2 software
can be installed before or after the R&S VSE software, if required.
Furthermore, an additional licence is required for R&S VSE (R&S®VSESIM-VSS).
1.
If necessary, install the Cadence®AWR®VSS software.
2. Install the R&S VSE software as described in "To install the R&S VSE software"
on page 25.
