Austin, Tex. National Instruments (NI) has released the NI PXIe-5672, a RF vector signal generator that delivers signal generation from 250 kHz to 2.7 GHz, 20 MHz of instantaneous bandwidth and real-time data streaming at up to 25 MS/s. The NI PXIe-5672 also features a PXI Express interface that makes it possible to stream data from hard disk or PC memory at the full output rate of the instrument, said NI.
The NI PXIe-5672 is compatible with all NI PXI, PXI Express modular instruments and NI LabVIEW modulation algorithms, making it easy for engineers to develop a complete PXI-based RF record and playback system, as well as broadcast video and general-purpose communication test systems, said NI.
The data streaming capability of the NI PXIe-5672 also provides significant benefits over traditional RF instruments, said NI. On traditional instruments, waveform generation and acquisition sizes are generally limited to several hundred megabytes because of bus bandwidth and onboard memory limitations. With the NI PXIe-5672 module, PXI Express technology makes it easy for engineers to use redundant array of independent disks (RAID) arrays to continuously stream waveforms that are up to 3 TB in size.
When combined with the NI PXI-5661 vector signal analyzer and the NI HDD-8264 RAID array, engineers have the ability to stream up to 20 MHz of RF bandwidth for more than five hours. Engineers also can use the NI PXIe-5672 to regenerate recorded waveforms in a laboratory environment. This technique for waveform generation improves the efficiency and accuracy of wireless receiver validation and verification by allowing for more repeatable channel emulation testing, said the company.
