Description
The product comes with two part numbers, where the Standard Module is identified as 780059-01, and the version that includes Sound and Vibration Measurement Suite Software carries the part number 780060-01. This differentiation ensures that users can select the variant that best suits their requirements.
The device is equipped with 24-bit, IEPE constant current signal module input channels, ensuring high-quality data acquisition from IEPE sensors. This feature is crucial for applications requiring precise vibration and sound measurements.
Synchronous sampling on all channels is supported, guaranteeing that data from all channels are captured simultaneously without any time delay between them. This is vital for accurate phase measurements and analysis in multi-channel applications.
To prevent aliasing, which can distort the signal, the device incorporates built-in antialiasing filters. These filters automatically adjust to the sampling rate, providing optimal performance without the need for manual configuration.
Users can adjust the input gain up to 20 dB through software selection, offering flexibility in managing signal levels for optimal data acquisition.
The device employs the NI-DAQmx driver and measurement services software, which is noted for not supporting Traditional NI-DAQ (Legacy). This ensures compatibility with the latest software standards and practices for data acquisition.
An advanced 24-bit delta-sigma Analog-to-Digital Converter (ADC) with digital filtering is utilized for precise signal conversion, ensuring that the data captured is accurate and reliable.
A Programmable Gain Amplifier allows for gain adjustments from 0 to +30 dB in 10 dB steps, providing users with the ability to fine-tune the signal amplification for improved measurement accuracy.
The device also supports TEDS Class 1 smart sensors, enabling users to read from and write to these sensors. This smart sensor support streamlines sensor configuration and enhances data integrity.
Lastly, it offers IEPE support, allowing users to turn the constant current on or off as selected in the software, which is essential for working with IEPE-compatible sensors for vibration and sound measurements.
