5.1 Zooming In/Out on Waveforms

Procedure

The following are three ways of zooming in and out on waveforms.

• By specifying a center wavelength (frequency / wavenumber) and display sweep
• By specifying a start wavelength (frequency / wavenumber) and stop wavelength

(frequency / wavenumber)

• By zooming in/out on a range specified with the mouse

The following explains the procedure for each of these methods.

Zooming In/Out by Specifying a Center Wavelength (Frequency /
Wavenumber) and Display Sweep

1.

Press

ZOOM

. The soft key menu for settings related to zooming in/out on a

measured waveform appears.

When Setting the Peak Wavelength (frequency / wavenumber) of the Displayed

Waveform as the Center Wavelength for Zooming

2.

Press the

PEAK ZOOM CTR

soft key. The peak wavelength (frequency /

wavenumber) is set as the zoom center wavelength (frequency / wavenumber).

Proceed to step 5.

2.

Press the

ZOOM CENTER

WL (FREQ / WNUM)

soft key. The zoom center

wavelength setting screen is displayed.

3.

Enter a zoom center wavelength using the rotary knob, arrow keys, or numeric

key pad.

4.

Press

nm/ENTER

.

5.

Press the

ZOOM SPAN WL (FREQ / WNUM)

soft key. A screen for specifying the

display sweep width (the range to zoom in/out on) is displayed.

6.

Enter a display sweep width using the rotary knob, arrow keys, or numeric key

pad.

7.

Press

nm/ENTER

.

Restores the zoomed waveform to its original size

8.

Press the

INITIAL

soft key.

Waveform display example

The zoom area is displayed

as a dotted line in the
