Quickly display a waveform (Autoset)
The Autoset function analyzes the signal characteristics and changes the instrument Horizontal, Vertical, and Trigger settings to
automatically display a triggered waveform. You can then make further changes to trigger and horizontal settings to view the
waveform point of interest.
1. Connect the probe with the signal of interest to an available channel. The signal can be analog or digital.
2. Double-tap the Trigger badge and set the trigger source to that of the signal of interest.
3. Connect any other associated signal(s) to available channel input(s).
4. Add the channel waveforms to the Waveform view. See Add a channel waveform to the display on page 35.
5. Tap File > Autoset or push the front-panel Autoset button. When using the Stacked Display mode, the instrument analyzes
the signal characteristics of the trigger source channel (analog or digital) and adjusts the horizontal, vertical, and trigger
settings accordingly to display a triggered waveform for that channel. The Vertical scale is adjusted in each waveform slice
of all active waveforms to maximize ADC utilization.
When using the Overlay Display mode, the instrument adjusts the horizontal and trigger settings of the trigger source
channel to display a triggered waveform for that channel. Vertical scale and position adjustments for all active channels in
Overlay Display mode are controlled by the Autoset in Overlay Display Mode Optimizes selection in the Autoset panel of
the User Preferences menu. If the selection is Visibility, Autoset vertically scales and positions all active channel
waveforms such that they are uniformly spaced on screen. If the selection is Resolution, Autoset vertically scales and
positions all active channel waveforms such that they each use as much of the ADC's range as possible.
NOTE. You can set which parameters the instrument can adjust when running an Autoset. See the Autoset panel in Utility >
User Preferences > Autoset.
Autoset guidelines:
■
Autoset displays three or four cycles (depending on the detected signal) with the trigger level near the midlevel of the signal.
■
The trigger is set to type Edge, rising slope, DC coupling.
■
If no channels are displayed before pushing Autoset, the oscilloscope adds Ch 1 to the Waveform view whether it has a
signal or not.
■
Autoset ignores math, reference, and bus waveforms.
■
A channel or waveform with a frequency less than 40 Hz is classified as no signal.
