Capture modes

PicoScope can operate in three capture modes: scope mode, spectrum mode and

persistence mode. The mode is selected by buttons in the Capture Setup Toolbar.

In scope mode, PicoScope displays a main scope view, optimises its settings for

use as a PC Oscilloscope, and allows you to directly set the capture time. You can

still display one or more secondary spectrum views.

In spectrum mode, PicoScope displays a main spectrum view, optimises its

settings for spectrum analysis, and allows you to directly set the frequency range in

a similar way to a dedicated spectrum analyzer. You can still display one or more

secondary scope views.

In persistence mode, PicoScope displays a single, modified scope view in which

old waveforms remain on the screen in faded colors while new waveforms are

drawn in brighter colors. See also: How to find a glitch using persistence mode and

the Persistence Options dialog.

When you save waveforms and settings, PicoScope only saves data for the mode that

is currently in use. If you wish to save settings for both capture modes, then you need

to switch to the other mode and save your settings again.
