Chapter 4 Observing Measurements and Data
4
Waveforms can be magnified (expanded or compressed) along
the time axis by changing the time per horizontal division.
Detailed waveform data is usually best observed with the time
axis expanded, while longer-term trends are best observed
with it compressed.
Horizontal magnification can be changed while measuring.
However, when measuring with auto saving enabled, the 100, 200 and 500 ms settings
are not selectable.
When the recording length of a waveform is long, you can
specify the portion to be displayed immediately.
This is available only when measurement is stopped. While
measuring, [Jump] is changed to [Trace] (p. 88).
Magnifying and Compressing Horizontally
Select from the [Horz] setting options.

When the A/B cursors are displayed, the position of
cursor A becomes the reference point.

The location of the currently
displayed portion of the over-
all waveform is indicated by
the mark on the scroll
bar.
