1 R&S ScopeSuite Overview
The R&S ScopeSuite software is used with R&S RTP oscilloscopes. It can be installed
on a test computer or directly on the oscilloscope. For system requirements, refer to
the Release Notes.
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 con-
figuration
●"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:

a) Right-click on the compliance test you want to hide.
The icon of the test changes, see Figure 1-1. Now with a left click you can hide
the test.

2 Preparing the Measurements
2.1 Test Equipment
For HDMI compliance tests, the following test equipment is needed:
●R&S RTP with 4 channels and minimum 8 GHz bandwidth
●R&S RTP-K101 HDMI compliance test option (required option, installed on the
R&S RTP)
●2 modular probes, R&S ZM160 with 9 GHz bandwidth.
●2 modular probe tips R&S RT-ZMA40
●HDMI Termination Module and a HDMI TPA adapter
●EDID Emulator
●The free-of-charge R&S ScopeSuite software, which can be installed on a com-
puter or directly on the R&S RTP.
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 Win-
dows " 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.
To install the R&S ScopeSuite
1. Download the latest R&S ScopeSuite software from the "Software" section on the
Rohde & Schwarz R&S 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 RTP.
For system requirements, refer to the Release Notes.
Installing Software and License

Preparing the Measurements
R&S®RTP-K110
8User Manual 1179.3196.02 ─ 01
To install the license key on the R&S 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 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.
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.
Starting the R&S ScopeSuite

R&S®RTP-K110
9User Manual 1179.3196.02 ─ 01
To start the R&S ScopeSuite on the instrument, in the R&S RTP firmware:
► In the "Apps" dialog, open the "Compliance" tab.
2.5 Connecting the R&S RTP
If the R&S ScopeSuite is installed directly on the instrument, the software detects the
R&S 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 RTP.
2. Start the R&S ScopeSuite software.
3. Click "Settings" > "Oscilloscope".
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.

3.2.1 General Test Settings
Each session dialog is divided into several sections:
●"Properties": shows the settings that can be made for the test case selected on the
left side of the dialog. You can differentiate between the "All" and the sub test prop-
erties
In the "All" > "Properties" tab you can configure the settings for all test cases in the
current session. Once you change and save a setting in this tab, the changes will
be done for all test in the sessions. At the same time, there will be a special mark-
ing for the functions that have different settings for different sub tests.
●"Limit Manager": sets the measurement limits that are used for compliance testing,
see Chapter 3.2.1.1, "Limit Manager", on page 15.
●"Results": shows an overview of the available test results for this session.
●"Instruments": defines instruments settings for connecting to external devices, that
are specific for this test session.
When a session is first created the global settings ("RSScopeSuite" > "Settings" >

3.3 Initiating the Test
To perform compliance tests, the device under test is connected to the test board in a
test-specific way. Using a probe, the test board is connected with the R&S RTP. The
probe connections are test-specific. The R&S ScopeSuite guides you step-by-step
through the connection setup and the test sequence.
1. Set the test setup on a nonconductive, static-approved work surface.
2. In the R&S ScopeSuite window, select the compliance test.
3. Open a test session, see Chapter 3.1, "Starting a Test Session", on page 12.
4. Check the test configuration settings and adjust, if necessary. See: Chapter 3.2,
"Configuring the Test", on page 13.
5. Click "Test Checked" for starting all checked test cases or "Test Single" for starting
only the selected test case.
The R&S ScopeSuite test wizard explains the following individual setup steps. A
detailed test description can be found in the following chapters:
●Chapter 4, "HDMI 1.4 Tests", on page 20
●Chapter 5, "HDMI 2.1 TMDS Tests", on page 30
3.4 Getting Test Results
If you resume an existing session, new measurements are appended to the report,
new diagrams and waveform files are added to the session folder. Existing files are not
deleted or replaced. Sessions data remain until you delete them in the "Results" tab of
the session.
The report format can be defined in "RSScopeSuite" > "Settings" > "Report" for all
compliance tests (see also Chapter 2.6, "Report Configuration", on page 10). If you
want to use special report settings for a session, you can define the format and con-
tents of the report in the "Report Config" tab of the session.
All test results are listed in the "Results" tab. Reports can be provided in PDF,
MSWord, or HTML format. To view and print PDF reports, you need a PDF viewer, for
example, the Acrobat Reader.
The test report file can be created at the end of the test, or later in the "Session Selec-
tion" dialog.
To show a test report
1. In the R&S ScopeSuite window, select the compliance test to be performed.
2. Select the session name in the "Session Selection" dialog and click "Show report".
The report opens in a separate application window, depending on the file format.
You can check the test results and print the report.
