National Instruments' FlexRIO product line has been expanded with six additional adapter modules for general-purpose automated test and high-speed digital communication.
The latest adapter modules includes four general-purpose digitizers, a module for high-speed digital I/O and a unit optimized for modulated communications which uses a AD9467 16-bit 250 MS/s analog-to-digital converter from Analog Devices.
FlexRIO solutions require two distinct hardware components – an I/O-specific adapter module and a PXI-based NI FlexRIO FPGA module, which features a Xilinx Virtex-class FPGA. There are 15 different NI FlexRIO adapter modules now available.
The six latest adapter modules are;
- NI 5762: 16-bit, 250 MS/s digitizer, featuring the AD9467 ADC from Analog Devices;
- NI 6587: 16-ch, 1 Gb/s digital I/O module for high-speed LVDS interfaces;
- NI 5731: 12-bit, 40 MS/s general-purpose digitizer adapter module, featuring typical SFDR better than -87 dBc;
- NI 5732: 14-bit, 80 MS/s general-purpose digitizer adapter module, featuring typical SNR better than 69 dB;
- NI 5733: 16-bit, 120 MS/s high-resolution digitizer adapter module, featuring 37 MHz of alias-free bandwidth;
- NI 5734: 16-bit, 120 MS/s, quad-channel, high-resolution digitizer adapter module.
The modules also integrate with the NI FlexRIO Instrument Development Library, a collection of LabVIEW host and FPGA code, designed to provide capabilities commonly found in instruments such as acquisition engines, DRAM interfaces and trigger logic, along with the associated host APIs.
The new NI-573xR Example Instrument Driver builds on the code from the Instrument Development Library to create a default FPGA personality and familiar host API for using an NI 573x adapter module as a basic digitizer.
NI FlexRIO FPGAs can be programmed with LabVIEW graphical system design software and the LabVIEW FPGA Module. This approach helps domain experts to target their applications to FPGAs without requiring VHDL knowledge, while still providing an interface to import existing VHDL code directly into LabVIEW FPGA.
