Dual Channel Acquisition
Combining Channels
Channels can be combined (also referred to as interleaved) to increase
sample rate, memory, and bandwidth. When you combine channels,
uncombined channels remain available for triggering, even though they
are not displayed.
In 2-channel operation, channels 2 and 3 are made active. Channels 1
or
2,
and 3
or
4 can be used in Auto operation for 40 GS/s. When channels are
paired in the following combinations, the maximum sampling rate is
doubled and the record length is greatly increased:
Channel Combinations Receiving 40 GS/s
Channels 1 and 3
Channels 1 and 4
Channels 2 and 3
Channels 2 and 4
Note
: These sample rates apply to all WavePro 7 Zi and Zi-Aoscilloscopes
(except the 715Zi, Zi-A without the 4x20 GS option).
In short, sampling can be maximized to 40 GS/s using two channel
combinations except for channels 1
and
2, or channels 3
and
4 (which
always yield 20 GS/s). Use best practice by choosing channel 1 or 2 for
your first input, and channel 3 or 4 for the second.
