Real-time and averagemeasurement
Real-time measurement canquickly judge basicfaults of opticalfiber. Press
button to start real-timemeasuring. During measuring,you can change
range, zoom inor zoom out. Press button again or button to
stop. The devicewill not analysesevent after real-timemeasurement in default.
Unless you turn on RT analyse in System settings, the device will analyse events
according to thelast refreshed waveform.
Average measurement canjudge the linecondition more accurate.It can geta
better SNR andfits high requirementcircuit. Press button to start. Usercan
set measurement timefrom 5 secondto 180 second.The device analysesevents and
generates event listautomatically. Press button during measuring,device
will stop measuring,analyses events andgenerates event listautomatically.

After measurement or open a waveform in memory, there is
event list onthe bottom ofwaveform interface. Press
button to showthe whole eventlist. Six typesof events as
followed:
Press Up orDown button toselect an eventwhich needs tobe
located by cursoron the waveform. Then press button
to return to waveform interface. The cursor will stay on the

The device supports userto change measurementrange during real-time
measurement. Start Real-time measuringfunction and pressUp or Downbutton to
increase or decreasethe range. Andit also supports tochange the cursorposition
and zoom in/outwaveform in realtime, which means you can zoom in partial
waveform while measuring to judge the network fault.
