The Network Image
2. Attach the previously created Network Image by selecting Network Image → Attach Network Image
3. In the resulting dialog, browse and select UMTS Cluster Drive.dat.
4. Select Open to attach to the Network Image. The workspace will update to reflect the change. Notice how quickly the Network Image attaches!
5. Expand the UMTS Device (Slot 0) stream. Display some parameters on charts, maps, and tables.
Key optimization parameters from three separate files have been combined into a single, smaller file that loads into Analyzer much faster than the original files!
Create a Custom Network Image Template
Some pre-configured Network Image templates are packaged with Actix solutions. It is also possible to create custom Network Image templates within the Analyzer workspace. This section describes the creation of custom Network Image templates using the Network Image Template Wizard.
To create a custom Network Image template, start the Network Image Template Wizard by selecting Network Image → Network Image Template Wizard from the main menu1. Complete each of the steps in the Wizard:
• Step 1 – Create a New Template / Open an Existing Template:
o To create a new template, click Next to continue.
1 If you plan to include any Queries in your custom Network Image template, ensure that the Queries are available in the workspace before beginning this procedure.

o To import and modify an existing template, click Open. Note that only templates created using the Wizard are fully supported. Older templates created by hand will be imported but may not behave as expected. In this case, a warning message will be displayed.

• Step 2 – Choose Your Devices:
o You may want to process different data streams in different ways. For example, you may want to extract different attributes for handset and scanner data captured in the same logfile. You can define a meaningful Device Name and specify a Filter to uniquely identify each device within a logfile.
When populating the Network Image, only data streams with names containing the Filter text will be processed into each device.
o If there are logfiles loaded into the workspace, the streams in those files will be displayed in the ‘Currently Loaded Devices’
panel on the left:
Figure 32 – Choose Your Devices
o Click the Add button to add a new device:
Introdu c tio n to A-RVS fo r UMTS
Figure 33 - Add Device Name Dialog
o Enter the Device Name and the related Filter that identifies the stream of interest within the logfile. The Device Name is a label that has meaning to the user. The software determines whether data from a stream should be loaded into the Device based on whether the Filter text matches any text in the data stream name. In this example, the Filter 0) uniquely identifies the UMTS handset stream in the file, while using an identifier that is common to many types of logfiles. If the Filter field is left empty, data from all streams will be loaded into the Device.
o Click OK to add the Device to the Device List.
o A Network Image template may contain multiple devices.
Once all the Devices have been entered, click Next to continue.

• Step 3 – Choose Your Attributes:
o Select a Device from the panel on the right, and then use the Add button to select the required attributes from the Attribute Picker panel on the left.
o If you select an array attribute (i.e. Uu_ActiveSet_EcNo[]), a dialog will prompt you for the range of indices. Enter the start and end values and click OK.
o In addition to standard analysis parameters, we recommend adding the Independent → FileName parameter to each Device in a Network Image. FileName can be used to trace data points in the Network Image to the original source file.
This method is used to perform detailed analysis on problems spotted in the high level Network Image.
o Attributes are assigned to one Device at a time. To duplicate the attributes selected for one Device into another Device, select the Device with the required attributes and click Copy.
Then select the second Device and click Paste.
o Once you have added all required attributes, click Next to continue.

• Step 4 – Choose Settings For Your Devices:
o To create a binned dataset, ensure the Binned checkbox is enabled and choose the appropriate Binning Settings. We
Introdu c tio n to A-RVS fo r UMTS
recommend the following Binning Settings for Network Images:
Time Binning – 3 second or larger bins
Location Binning – 50 x 50 meter or larger bins
o Select the appropriate UTM zone from which the file was collected.
o To create a histogram of the data, check the Histogram box.
o To create a statistical summary of the data, check the Statistics box.
o Note that Binning Settings are assigned to one Device at a time. Repeat this process for each Device.
o Click Next to continue.

• Step 5 – Choose Your Queries:
o Note that only queries available in the workspace can be added.
o Select a Query from the left pane.
o Select a Device from the right pane.
o Click Add to use the selected Query in the selected Device.
o Continue until all the required Queries have been added to the appropriate Devices.
o Click Next to Continue

• Step 6 – Confirm Your Selection:
o This window summarizes the contents of the Network Image template.
o After reviewing the contents, click Finish to open the Save As dialog.
o The Network Image template must be saved in C:\Document and Settings\All Users\Application
Data\Actix\Analyzer\Bin\ NetworkImageDefns or a subfolder. Saving in this location ensures that the template will be available as a selection in the Create Network Image dialog box. Enter a filename and click Save.

After saving the new Network Image template in the
\Bin\NetworkImageDefns folder, the template will be available in the Create Network Image dialog. You can now create and populate a Network Image repository using your custom template!
