If you are using an RTK solution to set start line(s), click the Add Start Line button to set a start line. This will add a virtual start line to the Chart and Map areas at the current location of the cursor. Once you have added a start line, you can specify the gate width.
Start Line 1 will be indicated by a green line. The currently selected gate is indicated by a dark blue line.
When you have added a gate, the name of the currently selected gate will be displayed in the name box. Click on the arrow in the box to see a dropdown list of all the added gates. The gates will be named according to the type of gate (if applicable) and the order it was added.
When you have added a gate, you can specify the gate width. The default gate width is 20 m.
Type the required width in the Width (m) value box.
Note: If you change the gate width, the last used gate width will be used as the default width for the next gate.
Click on the Rename button to edit the currently selected gate line.
Click on the Delete button to delete the currently selected gate line.
Click on the Delete All button to delete all set gates for the session.
Click on the Export button to export the created gate(s) as an .spl file. This file can be reused at a later date and with another VBOX product.
Click on the Import button to import a previously saved or provided .spl file. When the file is imported, the gates will be added in the order that they were saved in the .spl file.

The Add button adds a column to the Test Results area. Click this button to open a dropdown menu where you can select a channel to display in the test results window.
When you select a column header in the Test Results area, the channel name will be displayed in the Channel box (the top box in the Data Column section). Some columns will have required channels and cannot be changed, but if you can change the channel, the Channel box will become a drop-down list with the available channels.
When you select a column header in the Test Results area, and it is a changeable channel, the Condition dropdown menu becomes available. The conditions will depend on the test and selected channel.
Examples are:
- Avg
- Max
- Min
- Delta
- At Start
- At End
The Sort Ascending button will sort the values in the currently selected column in the Test Results area in alphabetical order from A to Z.

The vehicle offsets measurements are mandatory. The other data is optional and will not affect the test or test result.
Enter the front and rear vehicle offsets from the laser light trigger, or GNSS antenna if using GPS start/finish lines.
The start of the test is deemed to be when the front of the vehicle passes the start line and the end is when the rear of the vehicle passes the finish line.
When in Offline mode, the Session Data will be saved into the VBOX file. This information will be recalled every time the file is loaded into VBOX Test Suite.
When in Online mode, a newly created session will be populated with session data from the previous session.
To save time, you can import and export the session data for other sessions. When you have completed the Session Data, you can export the data to a .vbses file by clicking on the Export button in the Session Data window. The exported file will contain all the session data and can be imported into another session via the Import button in the Session Data window.

As the test can be conducted in both directions, you can set 1 or 2 Start On lines in this setting.
Start Line Offset (m)
Set the distance between the reflective strip and the Start Line (AA') in the test area.
To prevent situations where the start line offset is less than the vehicle front offset to the antenna, the minimum value of the Start Line Offset (m) is 5 m.
It is recommended that the reflective strip is located 30 m after the Start Line.
Use the arrow buttons next to the value box to increase/decrease the value or type the required value directly into the box.
End Line Offset (m)
Set the distance between the reflective strip and the End Line (BB') in the test area.
Use the arrow buttons next to the value box to increase/decrease the value or type the required value directly into the box.

You can rename a session tab by double-clicking the tab header. Changing the name on the session tab in the software will automatically change the name of the locally saved VBOX file (.vbo or .vbb).
By pressing the Edit Data button next to the name of the session in the Test Results area or on the Test Setup tab on the ribbon, you can add vehicle and test information to the session.
- When in Offline mode, this information will be saved into the VBOX file, meaning that this information will be recalled every time the file is loaded into VBOX Test Suite.
- When in Online mode, a newly created session will be populated with session data from the previous session.
This information will be included in the test report to make it easier to see under what conditions the test was conducted.
To save time, you can import and export the session information for use in other sessions (the entire range of data is exported, not just the visible screen).
Once the session information has been completed, you can export the data to a .vbses file. This file will contain all the session information that can then be imported into the open session information field.
The Test Results area has the following default columns:
There is also a selection box that, when ticked, includes that run in the graph and into the Average/Max/Min/Standard Deviation calculations. Once selected, a coloured square will appear to indicate which colour this run is displayed as on the graph.
| Note: If you are loading a file in Offline mode, all valid runs will automatically be ticked. |
The software will automatically add columns based on any specified pass criteria.
