Description
The PXI-6561 is a versatile digital waveform generator and analyzer designed by National Instruments, now considered obsolete but still available for purchase and repairs through Apex Waves. This device comes with part numbers 778993-01, 778993-02, and 778993-03, each variant differing primarily in onboard memory capacity. It operates on 16 channels with a maximum frequency of 100 MHz and utilizes LVDS signaling for robust, high-speed data transmission.
Depending on the specific model, the onboard memory per channel can be 2 Mb (778993-01), 16 Mb (778993-02), or 128 Mb (778993-03), providing ample space for user-defined waveform generation with no fixed limit on the maximum number of waveforms that can be stored in memory. Users can leverage two main generation modes: Single-waveform mode and Scripted mode, to tailor the waveform output according to specific test requirements.
The PXI-6561 features multiple triggers, including Start, Pause, Script, Advance, and Reference, which allow for precise control over waveform generation and analysis processes. It is supported by NI-HSDIO driver software, ensuring seamless integration and compatibility with various development environments. Specifically, it supports LabVIEW 7.0 or later, Microsoft Visual C/C++ 6.0 or later, and LabWindows™/CVI™ 6.0 or later. Additional software support includes the Digital Waveform Editor, Express VIs for LabVIEW 7.1 and later, and a Script Editor for advanced programming and customization options.
Physically, the PXI-6561 measures 8.5 x 0.8 x 5.1 inches and
