DT9837 Series USB Modules for Sound and Vibration Analysis
Models DT9837 (6069-410-142), DT9837A (6069-410-041), DT9837B (6069-410-048) With 4 Simultaneous Channel 24 bit ADC
The modules of the DT9837 series are high-accuracy dynamic signal acquisition boxes for Windows-PC/USB. The are an ideal solution 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. The DT9837 are rugged, compact, USB-powered modules for stationary as well as portable measurement applications.
- Four simultaneous analog input channels.
- 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 ±10 V with software-selectable gains x1 and x10 for an effective input range of ±10 V and ±1 V, respectively.
- 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.
- DT9837A, DT9837B: Read the value of tachometer counter 1 in the analog input data stream, allowing you to precisely correlate tachometer measurements with analog input measurements.
- DT9837B: 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.
- DT9837A: Support for reading analog output values in the analog input data stream, allowing you to correlate input and output values.
- Software-programmable trigger source (software trigger, external digital trigger, or analog threshold trigger) to start the analog input operation./li>
- Internal clock source (shared between the analog input and analog output subsystems).
- DT9837A and DT9837B: RJ45 synchronization (LVDS) connector for synchronizing acquisition on up to four modules.
- BNC connectors for all channels.
- USB 2.0 connectivity to a Windows-PC, USB-powered.
