Run/Stop/Single/Infinite Persistence Operation - Agilent Technologies 54622A User Manual

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
illuminated green), and stop the acquisitions by pressing
again (key is illuminated red).
• Take exactly one acquisition, then stop by pressing the
• Store the results of several acquisitions by using infinite persistence.
• Erase the results of all acquisitions by pressing
