Description
The PCI-6561 is a high-performance, PC-based digital instrument from National Instruments. It is designed as a Digital Waveform Generator, capable of generating signals at frequencies up to 100 MHz with a Low Voltage Differential Signaling (LVDS) interface and offers a memory depth of 2 Mbit per channel. This model is available under part numbers 778991-01, 778991-02, and 778991-03.
This device falls under the category of PC-based Digital Instruments and is equipped with 16 data channels, providing ample interfacing capability for complex applications. It boasts synchronization capabilities to ensure precise timing and coordination with other devices in a system.
For flexibility in signal generation, it supports various sample clock sources including an On-Board clock, CLK IN, and STROBE. The on-board clock frequency ranges from 48 Hz to 100 MHz, matching the input frequency range of 20 kHz to 100 MHz for the CLK IN terminal, and offering a STROBE frequency range also from 48 Hz to 100 MHz. The clock resolution is remarkably fine at 10 ps, allowing for precise timing adjustments.
The typical lock time for the device is 400 milliseconds, ensuring quick stabilization. It supports a reference clock frequency range of 10 MHz ± 50 ppm, providing stability and accuracy for timing-critical applications. Additionally, it offers a duty cycle range from 25% to 75%, giving users control over the waveform characteristics.
The PCI-6561 is accompanied by driver software, simplifying integration and use with various computing environments and ensuring users can leverage its full capabilities without undue complexity.
