User Interface Overview

Workspace

• “Measurements” tab in workspace is divided to three sections:– Folders

• “All measurements” folder in the workspace shows all files currently in the database

• Other user-defined folders where files can be grouped automatically, e.g., “All files from certain operator”, “All files from UMTS”

– Folder contents

• List of all measurements in the folder selected in the “Folders” section

– Parameter tree

• Shows all available parameters and KPIs for the selected file, measurement, or folder, depending on the selection in “Folders” and “Folder contents” sections

• KPIs can be displayed in graph, map, etc., or statistics can be calculated from the parameter tree

• Visible tab in the workspace can be changed from the bottom• Tabs:

– Measurements – Base stations– Maps– Data source files– Reports

Loading files into Nemo Analyze

• Select File | Open | Measurement/BTS/Map/Report or click the Open Measurement button

• Measurement files and BTS files are loaded in the database

• Maps and report templates are loaded in the workspace

• Note that all the files uploaded into the database need to have unique file names

• The added files will appear in the workspace view in the left-hand side of the Nemo Analyze main window

Organize measurements

• By default, all added measurement files go into the All Measurements folder

• Measurement files can be further grouped to folders• 3 different folder types:

– Drag-and-drop folder

• User can manually drag-and-drop the files to the folder

– Search folder

• User sets a criteria, based on which the measurement files are automatically added to the folder

• Folder contents is updated automatically when new files are added to the DB

• E.g. all files from last week, all files from UMTS, all files from certain operator

– Query folder

• Files to the folder are filtered based on user-defined SQL query

• E.g. all files with dropped RRC connections

Organizing Measurements-Drag&Drop Folder

Right click on Measurement, Add Folder/Drag & Drop…

Create a new folder, input folder name.

Drag & Drop measurement file into new folder

Removing Files from Drag&Drop Folder

Click on Measurement, Right click, Remove from Folder…

Organizing Measurements-Intelligent Folder

Right click on Measurement, Add Folder/Query…

Once the query is defined, Nemo Analyze will go through the measurement files in the database and automatically add all relevant files to the query folder.

Predefined queries or custom queries can be used to define the folder.

Organizing Measurements-Intelligent Folder

Joined Measurement

• With Nemo Analyze it is possible to join separate measurement files into a joined measurement. Joined measurements will be handled as one measurement file.

• Note that you cannot join overlapping measurement files. Files must have been recorded at different times.

• Right-click on All Measurements and select Add Joined Measurement

• The joined measurement appears in the Workspace and you can now drag & drop measurement files in it. Joined measurements are identified with a symbol.

Joined Measurement

Drag & Drop measurement files to joined measurement folder created.

15thSep2005 will be treated as a single measurement.

Organize measurements

• Right-click on “All measurements” folder Organize..

• In the Organize Measurements dialog you can conveniently handle and organize large sets of measurement files

• In the Organize Measurements dialog you can create new folders, make joined measurements, and remove files from drag & drop folders. Right-click in the left-hand panel to create new folders.

5. Set aliases for different graphs, i.e. what column will be in x-axis, what will be in y-axis, etc.

6. When finished, the query is available in the “User” branch in the parameter tree in Analyze workspace.

Adding Custom Queries to Analyze UIQuery Wizard

• Simple queries can be done with query wizard

• Joins are made automatically between tables that have relationships

• Time-based correlation is not done– If two selected tables don’t have relation,

result set will be Cartesian product of the tables!

Step-by-step procedure:

• Select tables from where data is get

• Select columns to be displayed from the table(s)

• Select column for ordering the results, if time based ordering is not sufficient

• Set filtering conditions for results

• Define aliases between controls and result columns (which columns will be x and which will be y in graph etc.)
