The National Instruments Digitizers/Oscilloscopes are available for several buses: PCI, PXI, PXIe, and USB. NI-SCOPE driver software can be used with National Instruments Digitizers. NI-SCOPE allows for easy integration with Visual C++, Visual Basic, NI LabVIEW, and NI Measurement Studio and is compliant with the IVI-Scope driver class specification. NI-SCOPE does not entail programming when it is utilized with the Scope Soft Front Panel. This driver software can accomplish numerous board synchronization and ongoing acquisition and comes with over 50 built-in measurement and assessment functions.
The National Instruments SCXI products were discontinued on September 28th, 2018. However, all SCXI modules, accessories, chassis, etc. are available for purchase and repairs by Apex Waves. Before the user sets up their SCXI system, these items are required: an SCXI Chassis (SCXI-2000, SCXI-1000, SCXI-1000DC, or SCXI-1001), a computer, NI-DAQ driver software, an SCXI cable assembly, SCXI modules, and terminal blocks to utilize in the chassis, and DAQ instruments or the SCXI-1200 DAQ Module. The chassis holds the modules and provides power, controlling the SCXIbus. The chassis has a digital bus, an analog bus, and a chassis controller to control bus functions. The analog bus transports analog signals from every resident analog input module to the DAQ instrument with a link from one module to the DAQ instrument. The DAQ instrument’s digital lines communicate with the SCXI chassis controller and manipulate the digital bus, which is in charge of chassis functions.
The National Instruments FieldPoint modular platform contains legacy products that are no longer sold by National Instruments, but they are still available for purchase and repairs at Apex Waves. A few of the best features of the National Instruments FieldPoint modules include the programmable power-up states, wireless and Ethernet connectivity, simple maintenance and installation, and they are autoconfigurable and hot-swappable. There are 2, 8, and 16-channel modules. The operating temperature range is from -40 to 70 degrees Celsius. A FieldPoint system is comprised of a minimum of one network module, one or more terminal bases, and at least one I/O module. For example, the National Instruments FieldPoint FP-1000 module links an industrial RS-232 network to FieldPoint I/O modules.
The FlexRIO family by National Instruments was created for scientists and engineers requiring the versatility of customized hardware at an affordable price. These products are ideal for applications, such as custom protocol emulation, RADAR/LIDAR, automated test, signals intelligence, accelerator monitoring/control, medical imaging, and communications. The FlexRIO products have features such as huge, user-programmable FPGAs and high-speed digital, analog, and RF I/O. The FlexRIO National Instruments products have two architectures available. One involves modular I/O modules which can be attached to the front of a PXI FPGA Module for FlexRIO and can communicate via a parallel digital interface. The other type of architecture utilizes high-speed serial converters and comes with integrated I/O and Xilinx UltraScale FPGA technology.
Many National Instruments devices utilize Analog-to-Digital Converters, which has many advantages, including improving preciseness and performance within a variety of applications. There are two key types of Analog-to-Digital Converters or ADCs used in National Instruments DAQ Devices: the Successive-Approximation-Register or SAR and Delta-Sigma ADC or DSA. The SAR type of ADC is utilized in NI-63xx X Series Devices and Modules, NI-60xx E Series Devices, several NI-61xx S Series Devices and Modules, and NI-62xx M Series Devices and Modules. However, the DSA type of ADC is utilized in NI-43xx SC Express Devices and Modules, NI-944xx DSA Devices and Modules, and several NI-92xx C Series Devices and Modules.
The National Instruments Frame Grabbers family contains devices for PXI, PXI Express, PCI, and PCI Express, allowing users to link to industry-standard camera buses, such as Camera Link, GigE Vision, and USB3 Vision. These devices have 1-4 ports. Certain devices have Power over Ethernet (PoE) or Power over Camera Link. Frame Grabbers are ideal for scientific imaging and machine vision applications, involving high data throughput, high-resolution, and/or high-speed digital imagining.
