3Hardware and Physical Setup
The Luna 6200 is a standalone, battery powered device that does not need to be connected to any
PC or other device to perform measurements.
Starting the System
To start the system, press the power button on the top. The power button will light, and the touch
screen will activate. The system will then automatically go into its application user interface (UI).
Shutting the System Down
To turn off the system, press and hold the power button for a ½ second. If the system does not
begin to shut down, press and hold the power button for 5 seconds to force the system to turn off.
Charging the System
The system should be charged using the included USB type C cable and AC power adapter. For
fastest charging and maximum battery life, the system should be charged while powered off.

4User Interface
Let’s take a tour of the application User Interface (UI). The tour will start with an introduction to the
UI layout, then further explains each UI components which includes Delay Plot, Event Table,
Measurement Control and Information displays.
UI Layout Overview
When you power on the system, the application UI screen appears automatically. The image below
(Figure 2) is an illustration of a typical UI screen after the system is first started by completing the
initiation procedures and taking a measurement.
The lower section of UI screen is the Delay Plot (LEFT side) along with an optional Event Table
(RIGHT side).
The upper section of UI screen is for the display of measurement controls and information, as well
as access to the menu for file operations
Each of the above UI components is further explained in the following titled sections, respectively.
Figure 2 UI Screen Layout

Page 8
Delay Plot
When you first open the application, the UI screen appears with the Delay Plot. The Delay Plot
screen displays acquired measurements in the Time Delay Domain (reflection amplitude vs length).
Figure 3 Delay Plot
The Delay Plot Screen allows the user to change the Cursor Type to one of four possible values by
choosing a Cursor Type selection in the upper right area of the plot:
•None –Only the graph of the acquired data is displayed
•Single –A single vertical cursor is shown that allows for RL and IL measurements to be made
•Vertical –Two vertical cursors are shown that can be used to make length measurements
•Horizontal –Two horizontal cursors are shown that can be used to make IL measurements
and compare the reflectivity of various features in the measurement
Cursors can be moved by dragging them across the screen. When the cursors are selected and are
being moved, they will change color to black (The cursor turns black when you press it, indicating
that it can be moved). Tapping once on the cursor will cause it to snap to the highest point within its
highlighted zone.
Plot Navigation
The plots shown in the OBR 6200 user interface can all be manipulated through touch actions on the
instrument’s screen.

Luna 6225

Panning –The plot can be panned over the X and Y axes by pressing and dragging at any point
within the plot.
Zooming –The plot can be zoomed using a two-finger pinch or expanding motion at any point
within the plot.
Constrained Panning or Zoom –It is possible to constrain the panning and zooming to one of
the two axes by first pressing on the desired axis. It will turn blue while panning and zooming
are constrained.
Plot Rescaling –Double press on an axis to scale it to fit all data in the range.
Single Cursor
The single cursor view provides a single vertical cursor with integration regions for measurement of
both the RL and IL across an event. The region with red highlighting is integrated to provide a RL
measurement. The two regions with grey highlighting are used to compute the IL. The
corresponding RL Width and IL Width can be change in Measurement Tab (Refer to “4.4.2.1
Measurement Tab”).
Figure 4 Single Cursor view
Vertical Cursor
The vertical cursor view provides two cursors that can be used to measure the length between two
events or measure the IL over any distance. The RL, position, and IL information is shown in the
upper right area of the plot, under the Cursor Type selection.

Horizontal Cursors
The horizontal cursors are used to compare the amplitude of two events in the data.
Figure 6 Horizontal Cursor view
It is important to remember that the amplitude data can be shown with varying levels of filtering
which may make reflection peaks look smaller than they truly are.

Event Table
The Event Table of the Luna 6200 software displays the return loss (RL) and insertion loss (IL) events
detected in the Time Delay Domain and gives location, return loss, and insertion loss data for those
events.
Figure 7 Event Table
Events
Events are determined using the measured return loss and insertion loss. The 6200 reports two
types of events: Return Loss and Insertion Loss Events.
A return loss event occurs when the measured return loss rises by the amount specified in the RL
Threshold (dB) control (For the RL Threshold (dB) control, refer to “4.4.2.1 Measurement Tab”).
An insertion loss event occurs when there is a significant amount of insertion loss that is not
associated with a return loss event. Insertion loss is calculated as half the difference between the
return loss before and after an event. (For IL Threshold (dB) control, please refer to “4.4.2.1
Measurement Tab”)
Note that most return loss events will also have an insertion loss that may pass the insertion loss
threshold. In these cases, the return loss event will take precedence, and the 6200 will mark only a
return loss event rather than creating a return loss event and an insertion loss event at the same
location.
The RL Width (m) control how wide of an area is used to calculate the return loss. This can have the
effect of combining closely spaced peaks into a single event. If desired, the RL Width can be adjusted
to a smaller value to make closely spaced peaks register as separate events. Likewise, the IL Width
(m) control has the similar effects on calculated insertion loss and IL events.

Turn Event Table Display On/Off
Event Table is displayed by default after you first open the application. Yet you have the option of
not showing the Event Table (giving its display estate to the Delay Plot so that the plot can be shown
on a larger area), which can be achieved by uncheck the “Events” view control in Settings and Tools
(please refer to “4.4.2.1 Measurement Tab”). You can turn the Event Table display back on, by
checking the “Events” view control in Settings and Tools.
Event Marks in the Delay Plot
You can check/enable the "Show Event Markers in Plot" checkbox to show vertical markers on all
event locations.
Figure 8 “Show Event Markers in Plot” enabled, showing vertical markers on all event locations.

Luna 6225
DOC000015_OBR 6225 User’s Guide Rev001
Page 14
Touching an individual event draws a marker at that event location. Touching the event again
removes the marker. If you are using Single, or Vertical cursors, touching an Event table entry snaps
the closest cursor to that event location.
Figure 9 Touching an individual event draws a mark at that event location (event 2 in example)
Double tapping an entry in the event table zooms the plot to that event's location.
Figure 10 Zooms plot to an individual event's location by double tapping its entry in event table (event 2 in example)

Measurement Control and Information
Overview
Most of items in the Measurement Control and Information section on the top of the UI screen are
explicit and straightforward. For example, a “Measure”button to initiate a measurement, the option
to change the channel that is being measured (Port A or Port B), a timestamp to display the date and
the time of the measurement taken, a battery indicator, etc.
In this section, focus of introduction is mainly on 1) the “Settings and Tools” that can be opened by
taping the Gear Tool Icon on the upper right corner of the screen; and 2) the “File Operations” menu
can be opened by either taping the Menu Button Icon on the upper left corner of the screen or
swiping gesture from left side edge of the screen to inside
Figure 11 “Settings and Tools” can be opened by tapping on the gear tool icon in upper-right corner of the screen; and “File
Operation” menu can be opened by tapping on Menu button icon in the upper-left corner of the screen.
Settings and Tools
Once the Gear Tool Icon is opened, “Settings and Tools” contains are shown/grouped in three
display tabs titled Measurement, System and About respectively. The three tabs can be switched by
tapping the tab titles on the top or by swiping the tab screen to right/left.

Measurement Tab
As shown in Figure 12, there are three groups of control options in the Measurement Tab, which are
titled as Measurement Options, Event Options and View.
Measurement Options
•Group Index –allows the user to specify the group index of refraction (range: 1 –4).
•RL Width and IL Width –allow the user to change the width of the integration regions that
are used for return loss and insertion loss measurements. In the Delay Plot, the single cursor
view provides a single vertical cursor with integration regions for measurement of both the
RL and IL across an event. The region with red highlighting is integrated to provide a RL
measurement. The two regions with grey highlighting are used to compute the IL.
•Length –allow the user to change the measurement range between 20 meter and 50
meter.
Event Options (would be grayed out/disabled if Events is unchecked)
•Min Location and Max Location –allows the user to specify the length/location range of
events reported in the Event Table.
•RL Threshold and IL Threshold –allows the user to specify threshold value for RL or IL for its
qualified as RL or IL events and to be reported in the Event Table.
View
•Gaussian Filter –if checked (by default), applies a Gaussian filter to the data to smooth out
the graph. This is turned on by default.
•Filter Size –sets the Gaussian Filter width in mm, options are 0.64mm, 1.28mm(default),
2.56mm, 5.12mm and 10.24mm.
•Events –If checked (by default), Event Table is displayed in UI. If unchecked, Event Table is
not displayed in UI, and Event Options settings would be disabled (grayed out).
