NTi firmware and software updates give better detail
NTi has released FX100 firmware and FX-Control software to allow recording of FFT and Impulse Response results with a higher resolution. The data can also be exported in various formats.
FFT analysis is available on two or four parallel channels, in a bandwidth from 5Hz – 80kHz and with a block-length of up to 2 million input samples, which gives a frequency resolution of 0.09 Hz.
This high density of information is designed to allow a comprehensive insight into the spectral composition of the recorded signal.
Besides the graphical display, the FX-Control software includes export of the full result vector data for further analysis.
