NI PXIe-5451 Waveform Generator

The NI PXIe-5451 waveform generator is a high-performance instrument designed to generate standard functions and user-defined arbitrary waveforms as part of a PXI system. Here are the details and features of this waveform generator:

Product Overview:

The NI PXIe-5451 is a 16-bit, 400 MS/s dual-channel arbitrary waveform generator.

It provides 2 single-ended and differential analog signal outputs for optimal flexibility and functionality.

Each output has 98 dB spurious-free dynamic range (SFDR) at 1 MHz (no harmonics) and better than -137 dBc/Hz phase noise density at 10 MHz (1 kHz offset).

The delay difference between the two channels is less than 25 ps.

Technical Specifications:

Resolution and Sampling Rate: 16-bit resolution per channel, 400 MS/s sampling rate.

Frequency and Bandwidth: 98 dB closed SFDR at 1 MHz; 145 MHz analog bandwidth.

Noise performance: ±0.34 dB flatness at 120 MHz after digital flatness correction; phase noise density <-146 dBc/Hz at 10 kHz offset; -160 dBm/Hz average noise density.

Memory: 128 MB, 512 MB, or 2GB of high-capacity onboard memory available.

Data transfer: >600 MB/s continuous data read and write speed to the host.

Functions and applications:

The NI PXIe-5451 is an ideal instrument for testing devices with I/Q inputs, generating multiple wideband signals, and as a baseband component of an RF vector signal generator.

It features onboard signal processing (OSP) functions including digital upconversion, pulse shaping and interpolation filters, gain and offset control, and a numerically controlled oscillator (NCO) for frequency shifting.

Common applications include prototyping, verification, and testing of semiconductor components and communications, radar, and military electronic systems.
