Pulse Width Modulation Input Card
What is the Pulse Width Modulation Input Card?
Concurrent’s FPGA-based Pulse Width Modulation (PWM) cards are ideal for use in high-performance hardware-in-the-loop (HIL) simulation and test applications. The PWM input card is designed for capturing pulse width modulated signals with high accuracy. It features a timing resolution of 15 nanoseconds and the ability to measure the frequency and duty cycle. The PWM input and output cards are fully supported by Concurrent’s RedHawk Linux operating system on iHawk simulation platforms. Multiple cards can be installed in a single system. A Molex LFH-60 connector is mounted on each card for connection to external devices.
