National Instruments 782353-01

The National Instruments 782353-01 (PXIe-6614) is a high-performance 8-channel PXI counter/timer module specifically engineered for applications requiring precision timing and measurement. This module supports a variety of functionalities, including encoder position measurement, event counting, and pulse width measurement, making it versatile for numerous applications. With 32-bit resolution, the 782353-01 provides accurate and reliable data acquisition under stringent conditions, featuring eight counters with a measurement frequency of 80 MHz. The integration of an oven-controlled crystal oscillator (OCXO) enhances measurement stability and ensures exceptional accuracy over prolonged use.

In addition, the module boasts a comprehensive 40-channel digital I/O interface, with each channel individually programmable for input or output. Enhanced data streaming capabilities are provided through a digital waveform generation FIFO with a capacity of up to 2,047 samples and a digital input FIFO that can handle up to 255 samples. The sample clock frequency can range from 0 to 10 MHz, offering flexibility across various data transfer methods, including DMA and programmed I/O.

The 782353-01 features programmable digital line filters with customizable debounce settings, essential for mitigating noise and ensuring precise timing signals. The timing I/O function allows the use of PFI lines for static digital I/O, timing operations, and broad-ranging applications. Additionally, the integrated frequency generator supports selectable base clocks of 100 kHz, 10 MHz, and 20 MHz, which can be outputted through any PFI, PXI_TRIG, or PXIe-DSTAR channel.

Designed to comply with PXI Express hardware specifications, the module is compatible with various PXI Express slots, including hybrid and system timing slots. It operates reliably across a temperature range of 0 to 55 °C and handles relative humidity levels from 10% to 90%, ensuring dependable performance in diverse conditions. Moreover, the 782353-01 meets rigorous shock and vibration standards, making it suitable for both industrial and military-grade applications.
