4.3 Starting and Stopping Measurement
62
Press the DISP key to go to the Waveform screen.
Press the START key to start measuring.
Make this setting either during or before measurement. When the pen is set to Down, the waveform
is being drawn. When the pen is set to Up, the waveform is not drawn. This setting applies to all
channels.
Press the STOP key to stop measuring.
When measurement is stopped, waveform data for up to 4,000,000 samples before the current point
can be played back (redrawn) by the pen, similar to using a video recorder, starting from any speci-
fied point. This operation applies to all channels. The playback speed can be specified. (It can also
be changed during playback.) Waveform is only playbacked on the screen and will not affect the
printout data. To print the same waveforms as shown on the screen, use hard copy (
 p.98).
