PLEASE NOTE THE FOLLOWING:

For 25 or 30 GHz models, you may elect to combine one or both
pairs of channels.

Combined channel buttons have a 30 or 45 GHz label depending on
your model. When these buttons are selected, the channel pair (or
group on 45 GHz models) is dedicated to achieving that level of
bandwidth throughput together. However, sampling rate for each
channel remains ≤ 40 GS/s.
On 25 and 30 GHz models, DBI enabled C2 and C3 traces achieve:

25, or 30 GHz (depending on your model)

80 GS/s

Interleaving of the memory to 512 Mpts/Ch
On 45 GHz models, DBI can be enabled in two channel mode to achieve
performance identical to that of the 30 GHz model, or it can be enabled on
the C3 trace to achieve:

45 GHz

120 GS/s

Interleaving of the memory to 768 Mpts
When DBI is selected, trace descriptor labels correspond with your choices.
For example, when both C1/C2 and C3/C4 pairs are interleaved:

C1 - Shown as inactive

C2 - Shown as active

C3 - Shown as active

C4 - Shown as inactive
