Output Enable
Software-selectable. When disabled, CH 0 out is terminated with a 1 W resistor with a value equal to the selected output
impedance.
Maximum Output Overload
The CH 0 output can be connected to a 50 Ω, ±12 V (±8 V for the Direct Path) source without sustaining any damage. No damage occurs if the CH 0 output is shorted to
ground indefinitely.
Waveform Summing
The CH 0 output supports waveform summing among similar paths—specifically, the outputs of multiple NI 5441
signal generators can be connected together.

Arbitrary Waveform Generation Mode

Specification Value Comments
Memory Usage The NI 5441 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.
Onboard Memory Size
Output Modes Arbitrary Waveform mode and Arbitrary Sequence mode
Arbitrary Waveform Mode
Arbitrary Sequence Mode
32 MB option: 33,554,432 bytes
In Arbitrary Waveform mode, a single waveform is selected from the set of waveforms stored in onboard memory and generated.
In Arbitrary Sequence mode, a sequence directs the NI 5441 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.
