1.5 Starting/Stopping Measurement

Starting a measurement

When you click the start icon, the instrument starts a measurement.

• Waveform data shown on the screen is cleared once the measurement starts.

• You can also start a measurement by inputting a signal into the external control terminal.

Refer to “12 Externally Controlling the Instrument” (p. 209).

Waveform display during measurement

In general, the waveforms appear after data with the specied recording length has been acquired.

When the measurement speed is relatively slow, the instrument displays waveforms while it is

acquiring the data.

However, even if a slow-speed range is set, the instrument may display waveforms after it has been

acquired the data of the whole waveform, depending on the overlaying or magnication setting.

To automatically save data during measurement

Refer to “Automatically saving waveform data” (p. 84).

Stopping the measurement

Clicking the stop icon once stops the measurement after the instrument has acquired the

waveforms with the specied recording length.

Click the stop icon once and click [OK] on the dialog box displayed to stop the measurement.

Operating the Waveform Screen

and Analyzing Data

You can analyze measured data with various functions including cursor measurement of input

waveforms and searches on the waveform screen. You can also change measurement conditions

or other settings on this screen.

Operation available on the waveform screen

Changing the display magnication of

waveforms

• Magnifying/demagnifying waveforms (p. 29)

• Magnifying a part of waveforms horizontally

(p. 33)

Using the trace cursors and horizontal

cursors

• Reading measured values (p. 20)

Moving the waveform display position

• Moving waveforms by dragging them

• Moving waveforms with the scroll bar

You can display or hide waveforms with [CH Info] set to [On].

You can also change waveform color.

• Clicking [Color] allows you to change the waveform display color.

• Clicking [Disp.] toggles between showing and hiding a waveform.

• Right-clicking [Disp.] toggles between showing and hiding waveforms acquired across all

channels.

Setting [CH Info] to [Level Monitor] allows display values of signals being inputted into measuring

modules.
