The NI PXI-6562 is a high-performance LVDS digital waveform generator and analyzer module for PXI systems. It delivers 16 channels of synchronized digital I/O with independent per-channel direction control in single-data-rate mode. Operating at clock rates up to 200 MHz, the module achieves data rates to 400 Mb/s in double-data-rate mode, making it suitable for low-voltage differential signaling applications in mixed-signal test environments.
