Combining Channels
Channels can be combined to increase sample rate, memory, and
bandwidth. When you combine channels, the remaining (uncombined)
channels are available for triggering, even though they are not displayed as
active on the screen.
Channels are combined in either of two ways depending on your
WaveMaster 8 Zi / Zi-A oscilloscope model.

Internally, using Digital Bandwidth Interleaving (DBI) on a 20 - 30
GHz 8 Zi unit or a 25 - 45 GHz 8 Zi-A unit.

Using an External Interleaving Device on a 4 - 16 GHz 8 Zi unit or a 4
- 20 GHz 8 Zi-A unit. Learn more by referring to Using the External
Interleaving Device in your online help or on teledynelecroy.com.
Using Digital Bandwidth Interleave (DBI)
Digital Bandwidth Interleave is a method for combining channels to double
bandwidth - just as oscilloscope manufacturers have for years interleaved
channels to double sample rate and memory lengths. Teledyne LeCroy's 8
Zi-A series makes use of 6th generation DBI technology providing the
highest possible performance.
Enter DBI mode from the TimeBase dialog at TimeBase → Horizontal
Setup....
For 25 and 30 GHz models (and additionally, the 20 GHz 8 Zi and Zi-A
model), the DBI portion of the TimeBase dialog contains buttons for C1/C2
and C3/C4.
A pop-up is shown when using the DBI button controls verifying the proper
connector saver (2.92 mm or 2.4 mm for 45 GHz).
