Zooming In/Out on Waveforms
Procedure
Zooming In/Out by Specifying a Center Wavelength and Display Sweep
Restores the zoomed waveform to its original size
IM 735302-01E
The following are three ways of zooming in and out on waveforms.
• By specifying a center wavelength and display sweep
• By specifying a start and stop wavelength
• By zooming in/out on a range specified with the mouse
The following explains the procedure for each of these methods.
1.
Press ZOOM. The soft key menu for settings related to zooming in/out on a
measured waveform appears.

Center Wavelength for Zooming
2.
Press the PEAK ZOOM CTR soft key. The peak wavelength is set as the zoom
center wavelength. Proceed to step 6.
3.
Press the ZOOM CENTER WL soft key. The zoom center wavelength setting
screen is displayed.
4.
Enter a zoom center wavelength using the rotary knob, arrow keys, or numeric
key pad.
5.
Press nm/ENTER.
6.
Press the ZOOM SPAN WL soft key. A screen for specifying the display sweep
width (the range to zoom in/out on) is displayed.
7.
Enter a display sweep width using the rotary knob, arrow keys, or numeric key
pad.
8.
Press nm/ENTER.
9.
Press the INITIAL soft key.
