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 Ordering Information NI PCI-5922 ........................................................................779659-OM1 NI PXI-5922 ........................................................................779153-0M1 1M Figure 1.
