This license enables software operation with and without an R&S instrument. It is,
for example, possible to read data from file without a connection to an instrument.
●
R&S®FS-K96
This license requires a connection to an R&S®FSV, R&S®FSVR, R&S®FSQ,
R&S®FSG, R&S®FSUP, R&S®FSW or R&S®RTO. No license has to be installed
on the instrument. A smartcard reader that contains the license (dongle) has to be
connected to the PC.
●
R&S®FS-K196
This license is an upgrade for the R&S®FS-K96 / R&S®FS-K96PC that adds functionality for measurements on waveforms other than OFDM. It enables software
operation with and without an R&S instrument. It is, for example, possible to read
data from file without a connection to an instrument.
Welcome to R&S FS-K96
Licensing the Software
Demo mode
Basically, you can use the software in demo mode if you have no license. The demo
mode has limited functionality, but you can analyze the I/Q data from sample files that
are delivered with the software.
If no dongle with a valid license is found, the software shows a dialog that asks you to
insert a smartcard with a valid license. Select the "Demo Mode" option to start the
demo mode. The sample signals are delivered with the software and are installed in a
subfolder of the software program folder.
%Application path%/SIGNALS/
Using the smartcard reader (dongle)
Before you can use the software, you have to load the license(s) on a smartcard (if you
already have one) or order a new smartcard (R&S FSPC). New license types are available as registered licenses (see below).
Note that you can upgrade the license from R&S FS-K96 to R&S FS-K96PC by ordering the license type R&S FS-K96U.
You can use the smart card together with the USB smart card reader (for SIM format)
supplied with the software. Alternatively, you can insert the smart card (full format) in a
reader that is connected to or built into your PC.
Note that support for problems with the smart card licensing can only be guaranteed if
the supplied USB smart card reader (for SIM format) is used.
1. With the delivery of the R&S FSPC you got a smart card and a smart card reader.
13User Manual 1310.0331.02 ─ 07
R&S® FS-K96/-K96PC/-K196
2. Remove the smart card.
3. Insert the smart card into the reader.
If the OMNIKEY label faces upward, the smart card has to be inserted with the chip
facedown and the angled corner facing away from the reader.
Welcome to R&S FS-K96
Licensing the Software
4. After pushing the smart card completely inside the USB smart card reader, you can
use it together with the software.
When you insert the USB Smartcard reader into the PC, the drivers will be loaded. If
your PC does not already have drivers installed for this reader, the hardware will not be
detected and the software will not work.
In this case, install the required driver manually. On the CD, it is in the folder
\Install\USB SmartCard Reader Driver Files, named according to the processor architecture (OMNIKEY3x21_x86... or OMNIKEY3x21_x64). Detailed information on the file content and the download location for updated drivers can be found in
the ReadMe.txt file in the same folder.
14User Manual 1310.0331.02 ─ 07
R&S® FS-K96/-K96PC/-K196
You may have problems locking a computer while the card is inserted, because MS
Windows tries to get log-in information from the card immediately after you have locked
the computer.
Solve this issue by changing a registry entry.
Either execute the registry file DisableCAD.reg in the same folder the USM Smartcard
reader installation files are located. Or manually change the entry.
●
Open the Windows Start Menu and select the "Run" item.
●
Enter "regedit" in the dialog to open the system reigistry.
●
Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
policies\system.
●
Set the value of DisableCAD to 0.
Note that security policies may prevent you from editing the value. Contact your IT
administrator if you have problems with editing the value or installing the drivers.
