NI 5412 Specifications

NI PXI/PCI-5412 14-Bit 100 MS/s Arbitrary Waveform Generator

Unless otherwise noted, the following conditions were used for each
specification:

• Interpolation set to maximum allowed factor for a given sample rate.

• Signals terminated with 50 Ω.

• Low-Gain Amplifier Path set to 2 V
Path set to 12 V

• Sample clock set to 100 MS/s.

Typical values are representative of an average unit operating at room
temperature. Specifications are subject to change without notice. For the
most recent NI 5412 specifications, visit

To access all the NI 5412 documentation, including the NI Signal
Generators Getting Started Guide, which contains functional descriptions
of the NI 5412 signals, navigate to Start»Programs»National
Instruments»NI-FGEN»Documentation.

Caution Hot Surface Allow the NI 5412 to cool before removing it from the chassis to reduce

risk of burns. Use caution when handling because recently used NI 5412 devices may
exceed safe handling temperatures.
