8.9 Magnifying and Compressing Waveforms
204
Data details can be observed by magnifying the waveform along the time axis.
Also, by compressing the time axis, overall waveform fluctuations can be readily
seen.
On-screen magnification and compression is based on the left edge of the
screen, regardless of whether A/B cursors are present.
The amount of magnification/compression can be changed after measurement.

With the Recorder function, display magnifications of × 4 and × 2 are available
only for on-screen display. For printing, each data point corresponds to one pixel
when magnification is × 1, so the resolution is the same as displaying at × 4.
To view the overall waveform
Move the cursor to the [Mag] (Magnification) button,
and press the F1 [Whole Wave] (Whole Waveform)
key. The full recording length of waveform is dis-
played.
Printing with different magnification of the horizontal axis
Set the magnification on the Print Settings screen.
See "Time Axis Magnification and Compression Settings" (⇒ p. 317)
When displaying a highly compressed waveform loaded from storage media,
there may be considerable delay before the waveform appears.
