120 dBc total harmonic distortion (THD) for lowest noise generation
2 channels with 3 programmable gain ranges
51.2 kS/s update rate for dynamic signal generation
100 mA current drive at up to 10 V per channel
Pairs with NI PXIe-4610 audio amplifier for high-power, low-noise signal generation
mXLR connector option for superior noise immunity
The NI PXIe-4463 dynamic signal generator offers best-in-class 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.
This signal generator contains two 24-bit digital-to-analog converters to allow for fully differential simultaneous generation at rates up to 51.2 kS/s. Complete with three gain ranges up to 10 V, the module is capable of outputting up to 100 mA.
Programming the NI PXIe-4463 with NI-DAQmx driver software is fast and easy. Driver calls allow for per channel output configurations. Use the two timing engines to perform multisample-rate applications on a single module and independently start and stop channels on a single module.
NI produces two connector variants of this signal generator: a standard BNC connector option and a more noise-immune mXLR connector. The mXLR connector is recommended for most audio testing applications for which cable-induced noise is a possible concern.
