PXIe Audio Analyzer
M9260A
M9260A is significantly different from the traditional general purpose PXI digitizer modules which are being used for today's audio measurement. In order to achieve fast test speed and high performance it comes with large one million sample arbitrary waveform buffer and one million sample "limitless" input buffer, as well as super-linear/low noise amplifiers and digital to analog converters. This enables M9260A's ultra-low residual distortion and high amplitude accuracy. M9260A is now an important part of Keysight Radio Test Solution, and may also be easily integrated into any audio related PXI test system with its developer-friendly drivers and commands.
