Portable high-precision measuring system USB, USB 2.0 High Speed (480Mbit / s).
The field of application are sound and vibration applications.
Precision measurements of microphones, accelerometers and other sensors with a wide dynamic range are easily possible.
Other areas: audio testing, acoustic and vibration analysis in the automotive industry and machine monitoring.
The system provides simultaneous recording of two channels and analog output of two channels with sample / output rates of 48, 96 and 192 kHz.
The device provides four simultaneous inputs with a resolution of 24 bits = 127dB, as sampling rates of 8/16/32/48/96 and 192 kHz per channel are supported.
As the analog digital converter PCM4220 from Texas Intruments was chosen. It has an anti-aliasing filter, and digital high-pass filter for removing
the DC offset. The input voltage ranges are ± 1V, ± 10V.
Each input is usable differential and single ended, + 20dB programmable gain, phantom power and a digital high-pass filter.
Setting the filter group delay between 39/fs and 21/fs respectively for two channels.
Channel 2-3 can be switched between analog capture and output. Output frequencies: 48, 96 and 192 kHz in 24-bit resolution, the
Output voltage range is ± 5 V.
Two tachometer inputs with a resolution of 32 bits and a cutoff frequency of 10MHz, the tachometer inputs are recorded synchronously with the analog values.
The inputs have an input overvoltage protection of ± 40 V on or off state. External power supply 220V AC / DC 5V included, as well
a single card license for the MAIExtensionsDAQ including easily expandable example programs for data data acquisition for example in the TAFFmat file format.
