4.1  Analyzing Waveforms

Switching the Waveform to Be Analyzed

When data measured under multi wavelength conditions is loaded into the AQ7280, a soft key for 
switching the waveform with the wavelength to be analyzed appears on the OTDR menu.

1.

  From the top menu, select 

OTDR

.

2.

  Press the 

Current Trace

 soft key to switch the waveform with the wavelength to be analyzed.

 

  

Switches the current trace

Switches the trace displayed on the screen

How to Use Cursors

1.

  From the top menu, select 

OTDR

.

2.

  Turn the rotary knob to display the cursor.

 

  

Cursor (crosshair cursor example)

Note

•  The direction that the cursor moves differs depending on the direction that you rotate the rotary knob.

  Clockwise: The cursor moves to the right.
  Counterclockwise: The cursor moves to the left.

•  If you turn the rotary knob counterclockwise to the point where the cursor reaches the left side of the 

screen, the cursor will disappear. If you reach the measurement end point, the cursor will not move 
forward even if you turn the rotary knob clockwise.

•  For details on the cursor display format, see section 3.2.
•  You can change the cursor movement resolution (fine or coarse). For the procedure, see section 3.3.
