Run/Stop/Single/Infinite Persistence Operation
During an acquisition, the oscilloscope examines the input voltage at
each input probe.
• For analog channels, the input voltage is determined by the vertical
volts/division settings.
• For digital channels, at each sample the oscilloscope compares the
input voltage to the logic threshold. If the voltage is above the
threshold, the oscilloscope stores a 1 in sample memory; otherwise,
it stores a 0.
To control the acquisition process, you can do the following:
• Perform continuous acquisitions by pressing
Run/Stop (key is
illuminated green), and stop the acquisitions by pressing Run/Stop
again (key is illuminated red).
• Take exactly one acquisition, then stop by pressing the
Single key.
• Store the results of several acquisitions by using infinite persistence
when the scope is running.
• Erase the results of all acquisitions by pressing
Clear Display in the
Display menu.
