What are the Pulse Width Modulation Cards?

Concurrent’s FPGA-based Pulse Width Modulation (PWM) cards are ideal for use in highperformance 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 output card can autonomously generate TTL pulse width modulation signals with a timing resolution of 50 nanoseconds and has the ability to program sine frequencies, PWM frequencies, dead-band and duty cycle in real-time.

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.
