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.
