Overview

The NI PXIe-5450 is a 16-bit, 400 MS/s, dual-channel arbitrary waveform

generator optimized for I/Q communications signals. Each of the differential

outputs features 98 dB of close-in spurious-free dynamic range (SFDR) at

1 MHz (without harmonics), better than -140 dBc/Hz phase noise density

at 10 MHz (1 kHz offset), and less than 25 ps channel-to-channel skew.

The NI PXIe-5450 is the ideal instrument to test devices with I/Q inputs

or to serve as the baseband component of an RF vector signal generator.

It also features onboard signal processing (OSP) functions that include

pulse shaping and interpolation filters, gain and offset control, and a

numerically controlled oscillator (NCO) for frequency shifting. Common

applications include prototyping, validating, and testing of semiconductor

components and communications, radar, and electronic warfare systems.

NI PXIe-5450 helps you integrate mixed-signal test systems by enabling

synchronization with other instruments such as vector signal analyzers/

generators, high-speed digitizers, digital waveform analyzers/generators,

and other signal generators. You can also synchronize multiple arbitrary

waveform generators to form a phase-coherent multichannel generator

for applications such as MIMO (multiple-input, multiple-output) or

beamforming antenna schemes.

Signal Quality

With 16 bits of resolution, the NI PXIe-5450 achieves a close-in SFDR

(without harmonics) of 98 dB at 1 MHz. Including harmonics and

measured from DC to 200 MHz, it achieves a 1 MHz SFDR of 75 dB and

a wideband SFDR of 70 dB at 60 MHz. This ensures the dynamic range

and out-of-band performance needed to meet the stringent demands of

baseband I/Q signal generation (Figure 1).

Figure 1. With its high sample rate and resolution, the NI PXIe-5450 generates

low-distortion, high-SFDR signals over a very high bandwidth (the noise floor is

limited by the measurement device).
