National Instruments PXIe-6548 PXI Digital Waveform Instrument

The 200 MHz, 32 Channel PXIe-6548 (Part Numbers: 781012-01, 781012-02, and 781012-03) is a PXI Digital Waveform Instrument by National Instruments. The device is operated using the NI-HSDIO driver software, in conjunction with the NI digital Waveform Editor (NI DWE). It is compatible with application development environments such as LabVIEW or LabWindows/CVI.

This Digital Waveform Instrument allows the user to adjust the information position to exact areas utilizing the information postpone abilities, which enables the user to change their information for the edge of the clock with a resolution of more than 150 ps for all inside produced frequencies. It is also possible to link and loop waveforms with no software lag by utilizing the scripting highlights of NI-HSDIO. This element can be used to compose waveforms to the deep onboard available memory and afterward control these waveforms with instructions written in the Script Editor. Users can accomplish advanced linking, looping, and data streaming for each channel (acquisition or generation) and scripting highlight of the NI PXIe-6548 module. The three part numbers for the PXIe-6548 differ in their onboard memory size. Part number 781012-01 has 1 Mbit, part number 781012-02 has 8 Mbits, and part number 781012-03 has 64 Mbits. The device is equipped with 32 bidirectional digital channels, has a maximum clock rate of 200 MHz, and a total power rating of 32.2 W.

To meet availability prerequisites for fast computerized applications, the PXIe-6548 module can be operated with an assortment of accessories, including the accompanying:

·         NI CB-2162 connector block

·         Shielded 50 Ω flying-lead link

·         VHDCI high-density connector

The PXI Express backplane offers an inherent basic reference clock for the synchronization of numerous computerized instruments in a framework. Users can synchronize different analog and digital modules on a picosecond level with the PXI platform. With these highlights, the user can perform tests on semiconductor gadgets, such as analog-to-digital converters (ADCs), ASICs, and microcontrollers. For instance, with a 16-bit, parallel interface, 200 MS per second double channel DAC, the NI PXIe 6548 can create data on 32 lines (constantly or in blasts) to test the DAC at its most extreme clock rate. The device weighs 519 g, and measures 21.6 x 2.0 x 13.0 cm in dimensions.
