Zooming in on a Waveform

To obtain a more detailed view of a waveform, you can zoom in on a waveform using the ZOOM function.

To zoom in on a waveform, do the following:

1	Display the ZOOM key labels.
	Observe that the trace is frozen,
	HOLD appears at the top of the
	screen, and the waveform is
	magnified.
2	Enlarge (decrease the time/div)
	or shrink (increase the time/div)
	the waveform.
3	Scroll. A position bar displays the
	position of the zoomed part in
	relation to the total waveform.

Figure 22. Zooming in a Waveform

Observe that the bottom of the waveform area displays the zoom ratio, position bar, and time/div (see Figure 22). The zoom range depends on the amount of data samples stored in memory.

From this point you can use the cursor function for further measurements on the waveform.

Tip

Even when the key labels are not displayed at the bottom of the screen, you can still use the arrow keys to zoom in and out.
