Simultaneous Display of Trace and Event Table
Display After performing an Auto Event Search, the trace and event table are simultaneously displayed on the screen. Alternatively, you can choose to display just a trace or event table on the screen. In the event table, symbols enable you to identify the types of events.
Auto Mode Measurement
Display5 By combining Auto Set and Auto Save functions, you carry out a
chain of processes automatically such as the following:Automatically detects the conditions of the
fiber being measured and automatically sets
the optimum measurement condition.Starts measuring the average automatically
when the measurement conditions are set.Automatically detects the reflection values,
positioning (distance) and the loss incurred
when the threshold value exceeds the preset
values.Stores the measurement results
automatically Into the specified memory.
Trace Fix Function
Display2 Can quickly and easily compare traces with
the trace fix function. This is a convenient
function to observe the characteristic differences
in multi-core fibers by core, and quickly
check where the core was bended, and the
loss characteristics.
Trace Fix Function
Display3
Multi Wavelength Continuous Measurement is a
function that allows you to switch the wavelength
being measured while keeping the same
measurement conditions. This is convenient
when you need to measure two wavelengths in a
single fiber.
AQ7932 OTDR Emulation software (option)
Display4
The AQ7932 OTDR Emulation Software can be used to create and edit waveform analyses and reports (total tables and waveform
graphs) based on data acquired by the AQ7260 OTDR. And this software can be run on a Windows-based PC.AQ7932 supports the AQ7260 (TRD) and Telcordia (SOR)
formats.
You can check file information before opening the file by the
Preview Function.
With the output layout display, you can check the contents of
reports as you create them.
