Description
Technical Specifications of the PCI-6561
The PCI-6561 is a high-precision device with a variety of specifications designed to meet a wide range of technical requirements. This device comes with part numbers 778991-01, 778991-02, 778991-03, indicating different variations or packages available.
One of the key features of the PCI-6561 is its frequency range, which spans from 48 Hz to 100 MHz when utilizing the on-board clock. For external clock inputs (CLK IN), the device can accept frequencies ranging from 20 kHz to 100 MHz. Similarly, the frequency range for the STROBE function mirrors that of the onboard clock, also ranging from 48 Hz to 100 MHz. This flexibility allows the PCI-6561 to be adaptable to various operational needs.
The clock resolution of the PCI-6561 is another critical specification, boasting an impressive 10 picoseconds (ps), which ensures high precision. The typical lock time for the device is 400 milliseconds (ms), allowing for quick synchronization. Additionally, the reference clock frequency range is specified at 10 MHz ± 50 parts per million (ppm), ensuring accuracy in time-sensitive applications.
Regarding the duty cycle, the PCI-6561 provides a range from 25% to 75%, offering considerable flexibility for various signal patterns. The device is supported by NI-HSDIO driver software, making it compatible with a wide range of development environments such as LabVIEW, LabWindows/CVI, Measurement Studio, Microsoft Visual C/C++, and .NET. This compatibility ensures that developers can easily integrate the PCI-6561 into their projects.
For configuration, the Measurement & Automation Explorer (MAX) tool is used, simplifying the setup process for users. The typical warm time for the device is 15 minutes, after which it operates at optimal performance. Accuracy for frequency measurement is rated at ± 100 ppm, ensuring reliable and precise measurements. Lastly, the weight of the PCI
