Analyzing Traces and Events

OTDR 117

Displaying the Graph in Full Screen

You can display the graph in full screen at any time, even when an

acquisition is underway. The graph will keep the same display options as in

normal view (grid, file name, zoom window, inverted colors).

You can start acquisitions directly (via the button located on the

front of your unit) without having to go back to normal view first. You can

switch from one wavelength to another.

The information that is displayed at the bottom of the graph depends on

the tab that was selected when you switched to full-screen mode. The

table below gives an overview of the information that is available in each

case.

As soon as a trace is displayed (new acquisition or existing file), zoom

controls are available (see Using Zoom Controls on page 123).

Note: If you want to use the zoom-on-event feature, you must select the

button from the Events tab before switching to full-screen mode.

Tab that was selected Displayed information in full-screen mode

OTDR Acquisition parameters (wavelengths appearing

on the list correspond to those that are selected in

the tab).

Events A table of events that can be viewed one event at a

time.

Measure Marker information and either the four-point event

loss, attenuation, reflectance, or ORL

measurement, depending on the type of

measurement that is selected in the tab.

Trace Info. No further information is displayed. Only the graph

is available.
