PXIe-4463

The PXIe‑4463 offers high dynamic range and THD+N for audio, acoustic, and vibration applications. It provides the high precision and dynamic range necessary for the most stringent audio generation requirements in a modular form factor. The PXIe‑4463 contains two 24-bit digital‑to‑analog converters to allow for fully differential simultaneous generation. Complete with three gain ranges, the PXIe‑4463 can generate current with programmable, per channel output configurations. The two timing engines allow you to perform multisample-rate applications on a single module and independently start and stop channels on a single module.
