The National Instruments PXI-6542 Digital Waveform Instrument is a versatile solution designed for advanced waveform generation and manipulation in mixed-signal testing environments. It features a Digital Waveform Editor, enabling users to create, modify, and import complex waveforms from popular spreadsheet formats and VHDL simulation libraries into ASCII or Value Change Dump (VCD) formats. This functionality allows for graphical representation and intelligent editing of waveforms, facilitating the development of new signals tailored to specific device requirements.

The PXI-6542 supports the construction of tightly synchronized mixed-signal test systems with 32 digital channels, offering per-channel direction control. For precision testing, the modules can be synchronized using a 10 MHz reference clock from the PXI backplane, with an option to connect an external precision reference through an SMB connector located on the front panel. The instrument operates at a maximum clock rate of 100 MHz and is equipped with NI Synchronization and Memory Core (SMC) technology to enhance performance.

Available models include variations with onboard memory sizes of 1, 8, or 64 Mbit, designated by part numbers 778953-01, 778953-02, and 778953-03, respectively. The PXI-6542 also provides comprehensive support for integration with NI LabVIEW, LabVIEW SignalExpress, and C programming environments. Although the PXI-6542 has been rendered obsolete by National Instruments, Apex Waves continues to offer these digital waveform instruments for ongoing sales and repair services indefinitely.

Technical specifications include dimensions of 21.6 cm × 2.0 cm × 13.1 cm and a weight of 12.1 oz (343 g), with a typical power consumption of 15 W and a maximum of 20.5 W. The instrument is backed by a warranty of 2 to 3 years, and user and maintenance manuals are accessible for download. For pricing information, please contact a sales representative.
