Other Key Productivity Tools (Continued)
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 µVrms noise floor at 1 mV/div,
100 µs/div setting.

resolution mode.
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).

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.
