Overview
National Instruments 5922 flexibleresolution digitizers feature two
simultaneously sampled channels, with
variable resolution. NI 5922 digitizers can
trade sampling rate for resolution to sample
anywhere from 24 bits at rates less than
500 kS/s to 16 bits at 15 MS/s. By combining
an NI 5922 with software such as LabVIEW,
you can create numerous different types of
instruments, such as DC and rms voltmeters, audio analyzers, frequency
counters, spectrum analyzers, IF digitizers, or I/Q modulation analyzers.
NI 5922 digitizers have low noise as well as low distortion, which is
possible because of the NI Flex II ADC.
Applications
Communications
xDSL
Wireless communications
Baseband I & Q
Biomedical and Scientific Research
Ultrasonic medical imaging
Mass spectrometry
Particle physics
Aerospace/Defense
RADAR, SONAR, and LIDAR
Satellite
Signal intelligence
Consumer Electronics
Performance Audio Test
• Stream data continuously from onboard memory to host
memory or disk
Timing and Synchronization
Because NI 5922 digitizers are built on the SMC architecture, you
can synchronize two or more digitizers for high-channel-count
applications, and build mixed-signal test systems using SMC-based
digitizers, arbitrary waveform generators, and digital waveform
generator/analyzers using TClk technology.
Software
• IVI-compliant NI-SCOPE driver for LabVIEW, LabWindows/CVI,
and Microsoft C++ and Visual Basic with more than 50 built-in
measurements
• Scope Soft Front Panel for interactive control
• NI Spectral Measurements Toolkit for sophisticated frequencydomain measurements in communications, signal intelligence,
and avionics applications
