K15 Short Introduction
Configuration
To run a measurement, you must configure hardware and software
according to your desired measurement scenario.
Before you configure a measurement scenario, set up the device, install the
measuring modules and switch on the device (see the Getting Started
chapter in the K15 User Manual).
The easiest way to configure a measurement scenario is to start the
autoconfiguration. The autoconfiguration configures measurement
scenarios for specific traffic types automatically.
To configure the K15 manually, you must load an existing or the default
configuration, which contains all available online and offline measurement
scenarios. Then you can adapt these scenarios to your specific needs.
K15 Short Introduction

Configuration
The configuration settings are made in the Data Flow window in the Cards
Overview and Measurement Scenarios tabs.
The Cards Overview and Measurement Scenarios windows consist of two
panes illustrating your settings:

between interface modules, data sources and measurement tasks are
depicted as tree structures.
a graphical representation of the configuration (interface modules or
pipelines).
The Measurement Scenarios tab of the Data Flow window displays the
current configured measurement scenarios and sources. This tab keeps
you informed about the currently active parameter settings and system
state at all times. The grey boxes in the pipelines represent pipeline
elements. The connecting lines indicate the data flow between those
elements.
Whenever the protocol tester is running, one configuration is always
active.

K15 Short Introduction
Configuration
After configuring your desired measurement scenario, you can save
configurations in setup (.s) files, which can be reloaded at any time. Thus,
you can use a given scenario repeatedly without having to specify
configuration parameters each time.
Configurations provide the following advantages:
H You can save predefined measurement configurations for use at a later
point in time.
H If a long-term measurement is interrupted due to a power failure, the
program loads the last used configuration and then continues the
interrupted measurement (Auto-Restart). If you have loaded a
configuration and changed it, it is important to save this configuration.
Otherwise the protocol tester will not apply your changes during
automatic start up.

Creating Measurement Scenarios
After startup and configuring the hardware, you must configure the
software. To configure the K15 measurement software you must first set
up a suitable measurement scenario.
In the K15 program, a measurement scenario is represented as a pipeline
of processing elements. Processing elements are all measurement modules
that are required for a measurement scenario.
You can adapt predefined scenarios to your individual measurement task
by configuring the processing elements in these scenarios.
12
K15 Short Introduction

K15 Short Introduction
Configuration
To configure a pipeline, proceed as follows:
1. Choose one of the pipeline buttons and drag it into the right window to
create a new scenario or connect it to an existing scenario.
The pipeline is inserted into the Measurement Scenario pane. The List
of Scenarios pane displays an entry for the new scenario.
2. Enter a name for the scenario in the List of Scenarios pane.
3. Configure the source. See Configuring Sources on page 16.
4. After configuring the source, you can configure the processing
elements for your measurement. See Configuring Processing Elements
on page 23.
You can configure several pipeline branches per scenario. For example you
may want to run an online measurement to analyze the received data in the
monitor window and simultaneously write it to a recording file.
The number of pipelines or pipeline branches that can be configured
depends on the available memory space on the interface modules. To avoid
unnecessary usage of the memory, create only the pipeline branches that
are actually required for the measurement. Refer also to the notes in the
Resources help topic.
NOTE. The analysis program Load Meter, which can run simultaneously
with measurements, indicates the memory capacity utilization on the
interface modules. If the Memory field of card 1 indicates that the limit has
been reached, you should remove one or more pipeline branches.
K15 Short Introduction
15
Configuration
Configuring Sources
To carry out a measurement with the K15 Protocol Tester, you must define
logical rules for the data flow that is to be measured. Those rules are for
instance the assigned protocol stack and the specified channel decoding
method.
Online Sources. To define logical rules for online measurements, you must
configure the Source processing element, which defines logical links
between the system under test and the protocol tester. Logical links are
signaling links that represent the online data.
To configure a Source, all boards required for the measurement must have
been initialized (check in the Status Window for boot ok); a pipeline must
have been created, and the Data Flow window must be open.
You can combine several logical links in a single source and assign them
to one or more measurement scenarios.
Offline Sources. Offline Sources are based on recording files. The settings
for the logical links of an offline data source (offline scenario, data
display) are saved in the recording file and can be changed to a limited
extent (link names, link colors, protocol stacks).
16
K15 Short Introduction
Configuration
Configuring Online Data Sources
An online source consists of a group of logical links. In the pipelines, an
online source is represented by the Source processing element.
Configure sources as follows:
1. Click on the Source (Src) processing element. The Logical Link Setup
dialog box opens. This dialog box looks different depending on the
chosen interface. The following figure shows the Logical Link Setup
dialog box for the STM-1 line interface:
Figure 9: Logical Link Setup dialog box
The selection lists on the left display the scenarios of the current
configuration and the logical links that are assigned to these scenarios.
You can add new links to the scenarios and edit as well as remove
existing links.
K15 Short Introduction
17
Configuration
2. Configure the settings of your data source in this dialog box.
3. Confirm your settings with Apply.
After defining one link, you can create more settings until all your
connections are defined.
If you want to create a new logical link with settings identical to an
existing one, select the appropriate logical link in the Logical Links of
Scenario list. Then click New.
NOTE. Most of the settings in the Logical Link Setup dialog box can only
be made if you stop the measurement first. To do this, set the ON/OFF
switch in all pipeline branches of the online scenario to OFF.
NOTE. Detailed information on the individual settings can you find in
the appropriate Help topics.

2. In the Mode list, select the mode defining how data will be entered in
the capture RAM:
H Ring Mode: When the capture RAM limit has been reached, data
continues to be added at the beginning of the memory area and
overwrites the oldest data entered. Ring Mode is particularly suited
for long-term measurements that you want to view on the monitor
without interrupting data recording.
H Linear Mode: The protocol tester writes data to capture RAM until
the memory area is full. No more data will be entered. Linear Mode
is suitable for scenarios that you have restricted in advance with
appropriate filter criteria.
3. Enter the size of the memory area in the Size text field. The size of the
capture RAM can be set anywhere between 16 kB and 256MB. It
depends on the memory available on the interface modules. The status
window indicates how much memory space there is for each module.
If you are running several measurements simultaneously and the
capture RAM exceeds a total of 256 MB, the value you entered will be
reduced automatically.

Configuration
ON/OFF Switch
Use the ON/OFF switch processing element to start, interrupt and
terminate online measurements.
As long as an ON/OFF switch processing element is still activated in a
pipeline, neither a pipeline’s data source nor the configuring pipelines
settings can be changed. In this case, you will be informed by an onscreen
message.
Filter
Use filters to reduce the amount of data to be evaluated (input filters) or
displayed (display filters). The protocol tester uses filter criteria to check
which data frames are allowed to pass for further analysis. Depending on
its position in the pipeline, the Filter processing element serves as input
(just after the Source) or display filter (just before the Monitor). You can
easily apply the settings of any one filter to another.
NOTE. For information on how to configure filters, refer to Configuring
Filters on page 83 or to the appropriate topic in the Online Help.
32
Trigger
With the help of triggers you can link events with predefined actions,
called trigger actions. Events are linked with a trigger as trigger conditions. If a trigger condition is fulfilled, the defined trigger action will be
carried out. A trigger condition, for example, is the receipt of a specific
message. A trigger action, for example, is the termination of a file
recording.
NOTE. For information on how to configure triggers, refer to Configuring
Triggers on page 95 or to the appropriate topic in the Online Help.
K15 Short Introduction
Saving Configurations
Configurations are saved in setup files. You can save any number of

K15 Short Introduction
K15 Measurements
With a configured K15 you can run several types of online and offline
measurements. You can edit your measurement scenarios by changing data
volumes or parameters. You can filter displayed messages and control a
measurement by configuring triggers.
The following chapter guides you through the different aspects of working
with the K15 Protocol Tester. It should help you get started by explaining
the basic principles of the protocol tester.
This chapter provides background information needed to access and use
the K15 features.
K15 Short Introduction
37
K15 Measurements
Selecting a Type of Measurement
After configuring the K15 you must select and start the desired measurement. There are two types of measurement scenarios – online and offline
measurements. They differ in terms of the data sources they use.
Online Measurements. Online measurements monitor “live” data as it is
received. The K15 is connected to the data lines being monitored.
Three measurement scenarios are available for online measurements:
H Online Recording (to record received data)
H Online Monitoring (to analyze received data in the Monitor)
H Online Statistics (to perform statistical analyses using received data)
Before starting an online measurement, you must configure at least one
logical link in a source.
Offline Measurements. Offline measurements use data stored in recording
files. The K15 is not connected to data lines.
Recorded data can be analyzed and processed in one of two ways: it can be
viewed or played back. Playback data reproduce an online measurement.
They can be edited and evaluated like online measurement data.
Four measurement scenarios are available for offline measurements:
38
H Recording Viewer (to view recorded data)
H Offline Recording (to filter recorded data and write it to a new
recording file)
H Offline Monitoring (to edit and analyze recorded data in the Monitor)
H Offline Statistics (to perform statistical analyses of the recorded data)
Before starting an offline measurement, select a recording file for viewing
or playback.
K15 Short Introduction
K15 Measurements
Online Recording
The Online Recording measurement scenario allows you to save received
data to recording files and evaluate them later.
You can reduce the amount of data being recorded using input filters. You
can set filter criteria for each event registered by the protocol tester,
specifying whether it should be recorded for later evaluation.
Figure 17: Online Recording measurement scenario
When using the Online Recording scenario, you can simultaneously
monitor your data using the Online Monitor and perform statistical
analyses using the Online Statistics by configuring appropriate pipeline

K15 Measurements
Online Monitoring
The Online Monitoring measurement scenario allows you to analyze ”live”
signalling data in the Monitor window. The data are displayed as they are
received and simultaneously stored in the Capture RAM. You can
passively monitor these data in the monitor window.
You can use input filters to reduce the amount of data entered into the
Capture RAM. In addition you can specify in the display filter, which of
the messages saved in the Capture RAM will be displayed in the monitor.

Monitor Panes. The monitor features three panes that display measurement
data at three different levels of complexity.
The Short View window pane lists the data packets (frames) recorded by
the K15, displaying signaling data in single rows and short form. The
preset columns display the time stamps, logical links, protocol names, and
messages of levels 2 to 4.
The Frame View window pane shows the frame selected in the Short View.
Here, it is displayed completely decoded down to the bit level. The first
column shows the selected octet, the second column shows the name /
meaning of the octet, and the third column shows the comment or value of
the parameter. The protocol stacks loaded with the scenario determine
which protocol parameters are shown.
The Packet View window pane displays the frame selected in Short View in

K15 Measurements
Reading Data as They Are Received (Live Mode)
You can view data simultaneously as they are received (LIVE). In the Live
Mode, incoming frames are displayed immediately (live), and the screen
scrolls automatically.
Live Mode is used for “passively monitoring” measurements. In Short
View, a new line is inserted for each frame that passes the Capture RAM.
This gives you a general impression of the signaling process over time.
The system continuously updates the displays in Frame View and Packet
View based on the signaling data transmission speed. In Live Mode there
are two display modes: Ring Live and Linear Live.
You can change the way newly received data are displayed in Live Mode.
In Ring Live Mode, new data overwrite the data that have already been
displayed, and the new line scrolls across the screen from top to bottom,
whereas in Linear Live Mode, the data already displayed scroll to the top.
In Ring Live Mode, new data can be displayed very fast. This is particularly useful if the protocol tester is controlled remotely.
You can switch between modes in two ways:
H In the Short View or Frame View context menu call up the Live Mode
Presentation menu item and select the Ring Mode or Linear Mode
setting.

Freezing the Display of Data (Freeze Mode)
You can freeze the display (FREEZE) for further data processing. In the
Freeze Mode scrolling is performed manually with the cursors. Freeze
mode suppresses the continuous display of new data allowing a more
detailed analysis of frames.
In Freeze Mode, the continuous display of new data frames is suppressed
(”frozen”), and you can select or search in the recorded data. Signaling
data received while you work in Freeze Mode continues to be recorded in
the Capture RAM.
NOTE. The Recording Viewer measurement scenario only supports
Freeze Mode.
You can switch between Live Mode and Freeze Mode in two ways:
H Select Live Mode or Freeze Mode in the Short View or Frame View
context menu.
H Click the active button in the Monitor toolbar: Live Mode or Freeze

main window title bar), you can read the data as it is measured. This mode
is set by default when you switch to the Monitor main window.
If you click on a view and scroll the contents using the arrow keys (↓ and
↑), the system automatically switches into Freeze Mode (indicated in the
main window title bar). The continuous display of new data frames is then
suppressed. In the background, measurement continues until the available
storage is full. Then you receive the following error message:
Data is not available! Change to Live Mode (and back to Freeze Mode) in
order to resynchronize Monitor Window and Capture RAM content.
Then click the Live Mode button to return to live mode.

Searching for Specific Data
You can carry out exact searches for specific messages or events in the received
data. The search for specific data “filters” the data in the Capture RAM.
NOTE. Depending on your display filter configuration, the display of the
data you search for may be suppressed even though they have been
recorded. To avoid this conflict, run the search function only if you have
not restricted the data display.
To search for specific data, proceed as follows:
1. Stop the current measurement by clicking the OFF button in online
pipelines or the Stop button in offline sources. Select a data frame.
2. To start a down search, press < CTRL > + < F3 > or select
Find –> Down from the Monitor menu.
For an up search, press < CTRL > + < SHIFT > + < F3 > or select

Restricting the Display of Measured Data Using a Display Filter
The display filter allows you to filter the display of the received signaling
data in the Monitor.
The display filter appears in the pipelines to the left of the Monitor
processing element. If you have deactivated the pipeline bar, reactivate it
or use the filter entry from the Pipeline Elements menu.
To configure the display filter, click on the Filter processing element. The
Filter Setup dialog box opens. You can now specify your search criteria.
This procedure is identical to defining a filter and is described in detail in
chapter Configuring Filters on page 83. You can define several criteria for
the search, for example, error events and messages.
Observe the following configuration notes:
NOTE. The filters allow you to adapt the recording and display criteria to
your specific measurement scenario. The protocol tester software does not
check your filter criteria specifications. It is therefore possible to define
mutually exclusive filter criteria.
Once you have configured the display filter, the name of the Filter
processing element is displayed in bold type.
The display configuration might impair the search function. When
searching in the recorded data, data frames that have been filtered out will
not be shown. Check the display filter settings and change them if required
before searching in the recorded data.
