Timebase
Timebase Dialog
You can access Timebase settings by:

Using the front panel Horizontal controls,

Choosing Timebase → Horizontal Setup... from the menu bar

Touching the Timebase trace descriptor label.
The main Timebase dialog contains sections for choosing Sampling
Mode, Timebase Mode, and Real Time Memory. Refer to Timebase
Setup and Control (on page 73).
A section specifically used for Combining Channels (below) is located at
the far right of the main Timebase dialog. This section varies based on
your oscilloscope model.
Combining Channels
Digital Bandwidth Interleave (DBI) is a method for combining channels
to double or triple bandwidth, sample rate, and memory lengths - just
as oscilloscope manufacturers have for years interleaved channels to
increase sample rate and memory.
When you make DBI selections, some system values are changed. View
these changes by touching the trace descriptor label for an interleaved
channel. In particular, The Vertical Scale B Scale V/div (Timebase) value
is automatically set to 50 mV/div. If you set this to a different value
after deactivating DBI, the system resumes the last one used with DBI
when DBI is reactivated.
