Description

The National Instruments PXI-6561 PXI Digital Waveform Instrument is a versatile testing tool with part numbers 778993-01, 778993-02, and 778993-03 representing different onboard memory capacities. This 16-channel instrument boasts a maximum frequency of 100 MHz and utilizes LVDS signaling for efficient communication. The onboard memory varies, with 2 Mb/channel for 778993-01, 16 Mb/channel for 778993-02, and a substantial 128 Mb/channel for 778993-03, catering to diverse application needs.

The device’s clock can operate within a broad frequency range from 48 Hz to 100 MHz, ensuring flexibility in synchronization for complex test setups. It features the advanced Synchronization and Memory Core (SMC) technology, providing users with the ability to define parameters such as the number of waveforms and samples stored in memory. The PXI-6561 offers two generation modes: a straightforward single-waveform mode for basic applications and a more complex scripted mode for sequences of waveforms.

Equipped with a suite of triggers, including Start Trigger, Pause Trigger, Script Trigger, Advance Trigger, and Reference Trigger, this instrument provides precise control over waveform generation and analysis. It is compatible with an array of software platforms such as LabVIEW 7.0 or later, Microsoft Visual C/C++ 6.0 or later, and LabWindows™/CVI™ 6.0 or later, ensuring seamless integration with existing development environments.

Despite its powerful capabilities, the PXI-6561 maintains a compact form factor, weighing just 12 oz. and measuring 8.5 x 0.8 x 5.1 inches in size, making it an ideal choice for space-constrained lab environments. Although it has been declared obsolete, the instrument remains available for purchase and repairs, continuing its legacy of performance and reliability.
