High-resolution mode for viewing signal details
To build more confidence in your designs, sometimes you
need to look into more signal detail than you can see with
the standard 8-bit vertical resolution of the 4000 X-Series.
High-resolution mode offers additional resolution and insight
into the signal, without requiring a repetitive signal. Using
real-time boxcar averaging, high-resolution mode reduces
random noise and effectively increases vertical resolution, up
to 12 bits. For example, it achieves the 113 uVrms noise floor
at 1 mV/div, 100 us/div setting.

resolution mode.

Freeze display
Perhaps you need to share with others an infrequent event
you found. With the “freeze display” feature, you can keep
intensity information on the screen while the oscilloscope is
stopped or before saving a screen shot.

information while stopping the waveform acquisition.

Advanced parametric triggering
With today’s more complex signals, you often need to
trigger on complex signal conditions to synchronize the
oscilloscope’s acquisition on specific events. The 4000
X-Series oscilloscope can trigger on the following conditions:
edge, edge then edge, pulse width (time-qualified), pattern, or,
rise/fall time, Nth edge burst, runt, setup and hold, video, and
various serial buses (optional).
