APCI-3600 Noise and vibration measurement board

1 Week Del.

Quick Overview

The new noise and vibration multifunction board APCI-3600 provides almost every functionality needed in acoustic processes.
View Options



Analog inputs (for all versions)
  • 8 SE or diff. (+/-) inputs
  • Sampling rate can be set between 2 and 200 kHz
  • SNR (signal/noise ration) > 105 dB
  • 24-bit resolution
  • One A/D converter per channel: simultaneous acquisition on all analog inputs
  • Gain 1 to 10, software-programmable
  • Input coupling AC, DC, GND, software-programmable for each channel
  • Antialiasing filter to avoid sampling errors
  • Overvoltage protection
Current sources
  • 4 current sources for the direct connection of ICP™ sensors (integrated circuit piezoelectric)
  • 4 mA typ., 24 V max.
Chronometer inputs (only for version APCI-3600)
  • 4 chronometer inputs, RS485, 32-bit for revolution counting
  • 2 gate inputs
Analog outputs (only for version APCI-3600)
  • 2 analog outputs: both outputs are started synchronously with the A/D converter. Arbitrary function generators can be programmed.
  • Settling time: 5 μs
  • 16-bit resolution
  • Simultaneous sampling on both channels
  • 13-bit accuracy
  • DAC type: R-2R
  • Output range: ± 10 V
Digital (only for version APCI-3600)
  • 8 digital inputs, 24 V, optically isolated
  • 8 digital outputs, 24 V, optically isolated
Onboard SDRAM module
  • 128 MB (256 MB or 512 MB on request)

The following applications can be realised with the APCI-3600:
  • Noise measurement with fault diagnosis on gear and drive over FFT: Encoders are connected to the chronometer inputs and microphones are connected to the analog inputs. Encoders measure the position of the drive and the analog inputs measure the noise of the system at a specific position. For this purpose the analog inputs and the chronometer inputs are controlled synchronously. To each analog sample belongs a position of the chronometer. The synchronisation results from a FFT.
  • Measurement of the transfer function of a DUT ("Device Under Test").
  • Noise analysis: Evaluation of a washing maschine, measurements in the automotive field, etc.
