1 R&S ScopeSuite Overview
The R&S ScopeSuite software is used with R&S RTO/RTO6/RTP oscilloscopes. It can
be installed on a test computer or directly on the oscilloscope. For system requirements, refer to the Release Notes.
R&S ScopeSuite Overview
The R&S ScopeSuite main panel has several areas:
●
"Settings": connection settings to oscilloscope and other instruments also default
report settings
●
"Compliance Tests": selection of the compliance test
●
"Demo": accesses demo test cases that can be used for trying out the software
without having a connection to an oscilloscope
●
"Help": opens the help file, containing information about the R&S ScopeSuite configuration
●
"About": gives information about the R&S ScopeSuite software
●
"Tile View": allows a personalization of the compliance test selection
You can configure which tests are visible in the compliance test section and which
are hidden, so that only the ones you use are displayed.
► To hide a test from the "Compliance Tests" view, do one of the following:

2.2 Installing Software and License
The preparation steps are performed only once for each computer and instrument that
are used for testing.
Uninstall older versions of the R&S ScopeSuite
If an older version of the R&S ScopeSuite is installed, make sure to uninstall the old
version before you install the new one. You can find the version number of the current
installation in "Help" menu > "About". To uninstall the R&S ScopeSuite, use the Windows " Control Panel" > "Programs".
For best operation results, we recommend that the installed firmware versions of the
R&S ScopeSuite and the oscilloscope are the same.
Preparing the Measurements
Setting Up the Network
To install the R&S ScopeSuite
1. Download the latest R&S ScopeSuite software from the "Software" section on the
Rohde & Schwarz R&S RTO/RTO6/RTP website:
www.rohde-schwarz.com/product/rtp.html
www.rohde-schwarz.com/product/rto.html
2. Install the R&S ScopeSuite software:
● On the computer that is used for testing, or
● On the R&S RTO/RTO6/RTP.
For system requirements, refer to the Release Notes.
To install the license key on the R&S RTO/RTO6/RTP
► When you got the license key of the compliance test option, enable it on the oscil-
loscope using [Setup] > "SW Options".
For a detailed description, refer to the R&S RTO/RTO6/RTP user manual, chapter
"Installing Options", or to the online help on the instrument.
2.3 Setting Up the Network
If the R&S ScopeSuite software runs on a test computer, the computer and the testing
oscilloscope require a LAN connection.
There are two ways of connection:
●
LAN (local area network): It is recommended that you connect to a LAN with DHCP
server. This server uses the Dynamic Host Configuration Protocol (DHCP) to
assign all address information automatically.

R&S®RTO-K81, R&S®RTO6-K81, R&S®RTP-K81/-K83
Preparing the Measurements
Connecting the R&S
If no DHCP server is available, or if the Tabor WX2182B or WX2182C is used for
automatic testing, assign fixed IP addresses to all devices.
●
Direct connection of the instruments and the computer or connection to a switch
using LAN cables: Assign fixed IP addresses to the computer and the instruments
and reboot all devices.
To set up and test the LAN connection
1. Connect the computer and the instruments to the same LAN.
2. Start all devices.
3. If no DHCP server is available, assign fixed IP addresses to all devices.
4. Ping the instruments to make sure that the connection is established.
5. If VISA is installed, check if VISA can access the instruments.
a) Start VISA on the test computer.
b) Validate the VISA address string of each device.

2.4 Starting the R&S ScopeSuite
To start the R&S ScopeSuite on the test computer or on the oscilloscope:
► Double-click the R&S ScopeSuite program icon.
To start the R&S ScopeSuite on the instrument, in the R&S RTO/RTO6/RTP firmware:
► In the "Apps" dialog, open the "Compliance" tab.
2.5 Connecting the R&S RTO/RTO6/RTP
If the R&S ScopeSuite is installed directly on the instrument, the software detects the
R&S RTO/RTO6/RTP firmware automatically, and the "Oscilloscope" button is not
available in the R&S ScopeSuite.
If the R&S ScopeSuite software runs on a test computer, the computer and the testing
oscilloscope require a LAN connection, see Chapter 2.3, "Setting Up the Network",
on page 8. The R&S ScopeSuite software needs the IP address of the oscilloscope to
establish connection.
1. Start the R&S RTO/RTO6/RTP.
2. Start the R&S ScopeSuite software.

Connecting the R&S RTO/RTO6/RTP
4. Enter the IP address of the oscilloscope.
To obtain the IP address: press the Rohde & Schwarz logo at the top-right corner
of the oscilloscope's display.
5. Click "Get Instrument Information".
The computer connects with the instrument and gets the instrument data.
10User Manual 1333.2299.02 ─ 05
R&S®RTO-K81, R&S®RTO6-K81, R&S®RTP-K81/-K83
If the connection fails, an error message is shown.
2.6 Connecting the Arbitrary Waveform Generator
Automatic test execution is possible with all instruments that are listed in the R&S ScopeSuite, in the "Instrument Settings" dialog box. In automatic mode, the R&S ScopeSuite configures the instrument and ensures that the AWG sends the required waveforms. Automatic mode requires a LAN connection and the installation of a VISA implementation (R&S VISA, see www.rohde-schwarz.com/rsvisa) on the computer that is
running the R&S ScopeSuite. If the R&S ScopeSuite is installed on the R&S RTO/
RTO6/RTP, no installation is needed because VISA is already installed on the instrument. If the Tabor WX2182B or WX2182C is used for automatic testing, fixed IP
addresses are required.
For manual test execution, it is recommended to use one of the listed AWGs, but you
can also use another AWG. In manual mode, you connect the AWG to the test board
and configure the instrument manually. VISA is not required. The R&S ScopeSuite
uses VISA if it is installed, otherwise it uses the VXI-11 protocol.
Preparing the Measurements
Connecting the Arbitrary Waveform Generator
To configure the arbitrary waveform generator for automatic testing
1. Connect the computer and the AWG.
2. Set up the LAN connection. See Chapter 2.3, "Setting Up the Network", on page 8.
3. In the R&S ScopeSuite, click "Instruments".
Alternatively, you can select the "Instrument" tab in the test case configuration dialog.
4. Click the "AWG" tab.
5. Select "Operating mode" = "Automatic".
6. Select a supported "AWG Type" and enter its IP address.
For a list of the supported AWGs, see chapter "Test Equipment".

7. Click "Get Instrument Information".
The computer or R&S RTO/RTO6/RTP connects with the instrument and retrieves
the instrument data.
8. If the connection to the arbitrary waveform generator failed, check if the IP address
is assigned correctly.
To configure the AWG for manual testing
► In the "AWG" tab, enable the "Manual" operating mode.
2.7 Report Configuration
In the "Report Configuration" menu, you can select the format of the report and the
details to be included in the report. You can also select an icon that is displayed in the
