Timebase Setup
Set up the timebase by using the front panel
Horizontal controls, just as for analog oscilloscopes.
Combining Channels
Channels can be combined to increase sample rate or memory (WaveRunner
44Xi can only be interleaved to maximize memory, not sample rate) in order to
capture and view a signal in all its detail. When you combine channels,
uncombined channels like EXT BNC remain available for triggering, even
though they are not displayed.
In 2-channel operation, channels 2 and 3 are active. In Auto operation, you can
use channel 1 or 2, and channel 3 or 4. On the paired channels the maximum
sampling rate is doubled and the record length is greatly increased:
Ch 1 & Ch 3 10 GS/s
Ch 1 & Ch 4 10 GS/s
Ch 2 & Ch 3 10 GS/s
Ch 2 & Ch 4 10 GS/s
As you can see, sampling can be maximized to 10 GS/s for any combination of
two channels, except a combination of channels 1 and 2, or channels 3 and 4,
which yield 5 GS/s. The basic rule is to choose either channel 1 or 2 for your
first input, or either channel 3 or 4 for the second input.
Refer to Acquisition Modes in the specifications for maximum sample rates.
