This presentation explains the difference between measurement cards with and without anti-aliasing filters.
In this example, a 30 kHz signal is input.
The USB measurement card without an anti-aliasing filter incorrectly measures a 14 kHz signal at full energy.
Data acquisition without an anti-aliasing filter is unsuitable for dynamic sensor signals and leads to measurement errors.
High SPL measurement microphone system according to MIL-STD-1474E.
This presentation illustrates a high-level microphone measurement using the LTTsmart NVH SET at a sampling rate of 1 MHz with 24-bit ADC resolution.
It includes the necessary anti-aliasing filters and IEPE sensor power supply.
In this presentation, I will demonstrate how infrasound and low-frequency building vibrations can be measured using a seismic accelerometer.
The measured structure-borne sound source, with a frequency of 80 Hz * 60 seconds, with 4800 rpm, is a NAS fan located in the corner of a building.
