2 Introduction
R&S TVSCAN2.0 is a software package that provides functionality to configure, control
and analyze measurements on TV signals. While measurement configuration and
result analysis are independent tools that do not need additional equipment, the measurement itself is only possible with a connected TV analyzer.
The container for all measurement information is a database, by default in a SQLite
database. You can also use other database formats, however.
This database collects the following data.
●
Measurement configuration files.
●
Data for each individual channel scan (measurements on certain frequencies).
Each channel scan evaluates various measurement results, for example the signal
power, the signal EVM, the signal BER.
●
Data for each scan, which consists of one or more channel scans.
●
Data for each measurement session, which consists of one or more scans.
You can analyze the measurement data in the database with the visualization tool.
For more information, see Chapter 5, "Visualization", on page 26.

Save all open configurations at the same time.
If one of the configurations does not have a file name yet, the R&S TVSCAN2.0
opens a dialog box to define a name.
Configuring the LAN connection
You can define the LAN connection with the "Connection (VISA Resource String)"
property.
Configuration
Device Configuration
1. Select the folder icon in the last column to open the "VISA Connection Configuration" dialog box.
2. Select the "LAN Connection" type.
Select "Local" if R&S TVSCAN2.0 is installed on the instrument itself.
3. Enter the "IP Address" of the instrument (not available for a local connection).
4. Adjust the "VISA Connection String", if necessary.
R&S TVSCAN2.0 automatically creates the VISA connection string based on the
connection type and IP address. So usually, it is not necessary to change it.

11User Manual 1178.9332.02 ─ 01
Page 12
R&S®ETL-K950 / R&S®DSA-K950
Defining measurement characteristics
1. Define the scan intervals "Repeating Time For Next Scan".
The scan intervals define the time after a subsequent scan starts, regardless of
how long the scan itself takes.
For example, if you define a time interval of 100 seconds, a scan is initiated every
100 seconds. If the scan itself lasts 10 seconds, R&S TVSCAN2.0 waits for 90 seconds until the next scan starts.
This setting only has an effect in continuous scan mode.
2. Define the maximum measurement time ("Maximum Duration for the Entire Measurement").
This setting applies to the overall measurement session, not a single channel scan.
Several channel scans can occur during the overall measurement. The measurement stops when it reaches the maximum time.
A value of 0 defines an infinite measurement time that you have to stop deliberately.
3. Select the "Error Behavior During Measurement".
This setting selects what happens in case an error occurs during the measurement. You can either stop the measurement, repeat it or ignore the error.
Configuration
Device Configuration
4. Select the "Instrument Impedance".
This setting selects the impedance for the RF connector of the connected instrument. For a comprehensive description, refer to the user manual of the connected
instrument.
For measurements with an R&S DSA, you must select 75 Ω, because it only supports that impedance. The R&S ETL only supports the 75 Ω impedance if you
equip it with option R&S ETL-B203.
5. Select the folder icon in the last column of the "Used Transducer File" property to
select a transducer.
For a comprehensive description of transducers, refer to the user manual of the
connected instrument.
6. Define the average count applied to the measurement ("Analog TV Analysis Average Count").
This setting defines the number of scans used to average measurement results.
7. Select the instrument behavior before the measurement begins ("Reset Device
Before Scanning").
● "Yes": Restores the default instrument configuration before initiating a scan.
During the scan, only the settings defined with R&S TVSCAN2.0 are changed,
if necessary.
● "No": Uses the current instrument configuration for a scan. Settings defined
with R&S TVSCAN2.0 are still changed during the scan, if necessary.
8. Select the instrument behavior after the measurement is done ("Restoration of the
Device Settings").

2. Select "Add New Channel" from the context menu.
R&S TVSCAN2.0 adds a column to the channel table. Add as many channels as
you need.
3. Define the channel properties.
For each channel, you can configure various parameters like the channel name,
the center frequency, reference level and others.
The channel name is also displayed in the channel matrix of the visualization tool.
Because the channel matrix only shows the first 4 characters of the channel name,
we recommend to define a channel name whose first 4 characters allow you to
identify the channel.
For a comprehensive description of all parameters, refer to the user manual of the
connected instrument.
If you cannot edit the value of a parameter, it is not available for the TV standard
you have selected.
Note: Reference level.
For the reference level, you can select the following settings:
● "Manual": Define a reference level that you like. For this mode, you have to
define the attenuation manually in the corresponding input field.
● "Auto": Determines the reference level depending on the currently measured
signal. This includes an automatic selection of the signal attenuation.
● "Time Optimized": Uses the reference level as the last measured channel of the
same TV standard.
4. Optional: Copy a channel configuration.
a) Click on the header cell of one or more channels to select a channel.

Filtering parameters
Some parameters in the channel table are only relevant for a specific TV standard and
are therefore probably not relevant for you. You can filter the list by a TV standard category (analog, digital and DocSis) and thus reduce the number of table entries.
1. Select the filter icon from the toolbar to open the "Select Filter Conditions" dialog
box.
2. Select the TV standard category you are interested in.
After you confirm your selection with "OK", the table only shows the parameters for
the selected category. If you filter by analog elements, for example, the channel
table only contains parameters necessary for measurements on analog TV standards.
The small "x" at the filter icon indicates if a filter is in use or not. If it disappears, a
filter is in effect.

Working with the limit table
Each line in the table corresponds to one specific measurement result. For each result,
you have the following options:
1. The "Type" column shows the type of TV standard the result belongs to (analog,
digital or DocSis).
2. Select if the corresponding result is evaluated during the measurement in the
"Measure" column.
3. The "Name" column shows the name of the measurement result. Some results are
specific to a certain TV standard, others are global. You can filter the results by a
certain TV standard with the filter icon. See "Filtering result types" on page 17 for
details.
4. Select the limit check logic in the "Comparison" column.
● "Not Used": Does not check against a limit.
● "Equal": Result must have the exact same value for a pass. All other values
result in a failed limit check.
17User Manual 1178.9332.02 ─ 01

If you want to use an updated version of one of the configuration files used in a measurement set, you have to replace those files deliberately. The configuration files in a
measurement set are not updated automatically after they have been changed.
For a comprehensice description on how to do that, see "Changing the configuration in
a measurement set" on page 19.

Configuring the LAN connection
By default, the measurement set already contains details about the LAN connectionLAN connection. Only change the connection properties if the LAN configuration is
different to those defined in the measurement set.
The LAN properties you define here are not transferred to the measurement set and
will be lost when you close the measurement tool.
1. Select the connection icon from the toolbar to open the "VISA Connection Configuration" dialog box.
2. Select the "LAN Connection" type.
3. Enter the "IP Address" of the instrument (not available for a local connection).

Using the visualization tool requires measurement data that you have recorded previously.
27User Manual 1178.9332.02 ─ 01
Page 28
R&S®ETL-K950 / R&S®DSA-K950
For more information about recording measurement data, see Chapter 4, "Measure-
ment", on page 21.
1. Select the folder icon from the toolbar to load measurement data.
You can load either a measurement set linked to a SQLite database or a SQLite
database directly.
2. Select the measurement or database you want to evaluate.
R&S TVSCAN2.0 opens a list of measurement sessions that are included in the
database.
The list contains information about each session. This information includes number
of scans performed during that session, the date of the last recording, the instrument it was recorded with, the measurement site and the description of the measurement.
Note: The evaluated limits depend on whether you load a measurement set or a
SQLite database.
● If you load a SQLite database, the visualization tool always evaluates the limits
originally linked to the measurement session. Different sessions may have different limits.
● If you load a measurement set, the visualization tool evaluates the limits that
were active during the last measurement session. All sessions will have the
same limits.
Visualization
General Operation
3. Select the measurement session you want to evaluate with a double-click.
R&S TVSCAN2.0 opens a tab in the user interface with the data of the measurement session.

5.4 Scan Result Summary
The scan result summary is a numerical result summary that contains the properties
and results of a certain channel scan. A measurement property is, for example, the
attenuation during the channel scan.
The contents of the table are variable and depend on the channel scan you have
selected from the channel matrix.
Each row in the table corresponds to a measurement property or result that was evaluated for the selected channel. The columns show the following information.
●
"Name": Type of the measurement property or result.
●
"Comparison": Shows the logic of the limit check.
●
"Lower Limit": Shows the lower limit if one has been defined.
●
"Measured Value": Shows the actual measurement result.
If the measurement result violates the defined limits or if the actual setting is not
the expected one (on instead of off, for example), the cell is highlighted red.
If the measurement result is not valid (for example if a communication error
occurs), the result is written in yellow font.
●
"Upper Limit": Shows the upper limit if one has been defined.

5.5 2D Diagram
The 2D diagram is a diagram that shows a measurement session's results for a certain
channel over time. You can view one or more different results and channels in the diagram. If you select more than one graph, each graph has a different color. The graph
itself shows discrete measurement points, each of which corresponds to a single channel scan. The number of measurement points therefore depends on the number of
channel scans performed for a certain channel in the measurement session.
The x-axis is a time axis, whose origin corresponds to the first channel scan. Channel
scans appear in ascending order.
