Pan
and
Zoom Pan
and zoom features
are
available in
the
real
time acquisition mode and
operable
only
when
the
acquisition
is
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
on
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,
or
sompression
of a singls-5he1
waveform
in the real
time acquisition
mode. Decreasing
tims/div
expands
the
waveform
and
is referred
to
as
nzoomingin".
lncreasing
time/div
compresses the
waveform
and
is
referred
to as
n2s6ming
out".
Panning
is moving the acquired waveform
horizontally
on the
display.
It
is
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.

Thiq
exercise
shows
how
the timebase is used to
zoom in
on
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
AC
CALIBRATOR
signal
of
the HP
545104
to channel 1.
Press AUTOSCALE. The rear-panel
signal
is
displayed
on screen as
in
frgure 4-10.
