Output Paths
1. The software-selectable Main Output Path setting
provides full-scale voltages from 12.00 Vpk-pk to
5.64 mVpk-pk into a 50 Ω load. NI-FGEN uses either the
Low-Gain Amplifier or the High-Gain Amplifier when
the Main Output Path is selected, depending on the Gain
attribute.
—
2. The software-selectable Direct Path is optimized for
IF applications and provides full-scale voltages from
1.000 Vpk-pk to 0.707 Vpk-pk.

Waveform and Instruction Memory Utilization
Specification
Value
Comments
Memory Usage
The NI 5421 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.

—
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 5421
to generate a set of waveforms in a particular 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)
the waveform is generated, and which sample in the
waveform a marker output signal occurs.
