Memory
Usage
The NI 5422 uses the Synchronization and Memory Core
(SMC) technology in which waveforms and instructions
share onboard memory. Parameters, such as number of
segments in sequence list, maximum number of waveforms
in memory, and number of samples available for waveform
storage, are flexible and user defined.

Output Modes Arbitrary Waveform mode and Arbitrary Sequence mode —
Arbitrary
Waveform
Mode
In Arbitrary Waveform mode, a single waveform is selected
from the set of waveforms stored in onboard memory and
generated.
—
Arbitrary
Sequence
Mode
In Arbitrary Sequence mode, a sequence directs the NI 5422
to generate a set of waveforms in a specific order. Elements
of the sequence are referred to as segments. Each segment is
associated with a set of instructions. The instructions
identify which waveform is selected from the set of
waveforms in memory, how many loops (iterations) of
the waveform are generated, and at which sample in the
waveform a marker output signal is sent.
