Pan

and

Zoom Pan

and zoom features

are

available in

the

real

time acquisition mode and

operable

only

when

the

acquisition

stopped.

Applications

that require

precise

evaluation of

low repetition rate signals,

such as

radar

and

transponder

pulse

treins, are simplified

by zooming

and

pan"ing

single-shot data.

Zooming

either expands or compresses

the

acquired waveform

on the

horizontal

axis of the display.

It is

controlled by the timebase

time/div

control for

expansiog

magnification,

sompression

of a singls-5he1

waveform

in the real

time acquisition

mode. Decreasing

tims/div

expands

the

waveform

and

is referred

nzoomingin".

lncreasing

time/div

compresses the

waveform

and

referred

to as

n2s6ming

out".

Panning

is moving the acquired waveform

horizontally

on the

display.

controlled

by the timebase delay control.

Increasing

the delay moves

the

waveform

to the

left

and

increasi'g

the

delay moves

the waveform to

the right.

Exercise

exercise

shows

how

the timebase is used to

zoom in

and

zoom out

ef 3

singls-5fuot waveform. The delay timebase is then

used to

pan

the

waveform

horizontally

on the

display.

Using

a coaxial cable, connect the rear-panel

to channel 1.

Press AUTOSCALE. The rear-panel

displayed

on screen as
