(Sound & Vibration Analysis)
High Performance, USB Powered Modules for Sound & Vibration Analysis
The VDT-9000-4Series high-accuracy dynamic signal acquisition modules are ideal for portable noise, vibration,
and acoustic measurements. Four, 24-bit, IEPE (ICP®) sensor inputs are synchronized with a tachometer input
(depending on model) to provide data streams that are matched in time, for field and laboratory use.
These rugged, compact modules are USB powered, making them ideal for portable measurement applications.
• Runs on USB Power – ideal for
portable applications
• Four Simultaneous, 24-bit Delta-Sigma A/D converters for high resolution measurements
• Support for IEPE (Integrated Electronic Piezoelectric) inputs, including use of a 2 mA or 4 mA current source and
AC or DC coupling
• Up to 105.4 kS/s sample rate per channel
• Input range of ±10 V with software-selectable gains of 1 and 10 for an effective input range of ±10 V and ±1 V,
respectively
• For VDT-9000-4 modules only, 1 Hz high-pass filter on analog input subsystem
• Return the value of tachometer counter 0 in the analog input data stream, to measure the period or frequency
of the tachometer input signal synchronously with analog input measurements
• For the VDT-9000-4 and VDT-9000 modules only, the ability to read the value of tachometer counter 1 in the
analog input data stream, allowing you to precisely correlate tachometer measurements with
analog input measurements
• For the VDT-9000-4 and VDT-9000 modules only, the ability to read the value of gate counter 2 in the analog
input data stream, allowing you to precisely correlate gate input measurements with analog input measurements values
• Software-programmable trigger source (software trigger, external digital trigger,
or analog threshold trigger) to start the analog input operation.
• Internal clock source (shared between the
analog input and analog output subsystems)
Analog output subsystem (VDT-9000-4)
• One 24-bit D/A converter
• Single value, waveform, and
continuous streaming output
• Programmable output rate from 10
kS/s to 52.734 kS/s
• Output range of ±10 V
• ±3 mA output current
• Software-programmable trigger source (software trigger, external digital trigger,
or analog threshold
trigger) to start the analog output operation.
Supported Operating Systems
• Windows® 10/8/7/Vista® 32/64-bit
• Linux® (supported by VDT-9000-4 modules only)
