The RX0224 is part of VTI’s RX0XXX family of rugged instrument with built in sensor signal conditioning. All connections and operations are designed for rugged operation by using Mil-Grade connections for all inputs. The RX0224 is capable of:
- 24 channels of charge signal conditioning and simultaneous sampling ADC
- Ethernet interface for simplified scalability and distributability of measurements
- 24-bit A/D converters per channel with selectable sample rate of up to 128Ksa/s
Although the RX0224 has a single-ended charge converter, it behaves as a differential charge input that provides common mode rejection. This is because it operates from an isolated power supply.
PRECISION ACCURACY FOR HARSH ENVIRONMENTS
The RX0224 is designed to allow users the ability to record charge type transducers in harsh environments. Multiple input ranges and 24 bit ADC per channel allow for very high resolution measurements so that large or small vibration events can be accurately captured.
Micro-dot connections provide direct connection for each input channel and the ability to select either single ended or differential inputs gives users more flexibility with a wider range of charge input devices. Power and communications are done using Mil-Standard type connectors for maximum reliability.
SELF-TEST DIAGNOSTICS
The RX0224 has a built in health monitoring capability. This allows for close monitoring of functions, including:
- Input charge ranges
- Volatile and non-volatile memory of the system
- Closed loop end-to-end self-calibration to help ensure maximum accuracy over time and temperature

BUILT-IN SIGNAL PROCESSING
The RX0224 leverages its internal FPGA for all necessary signal processing and provides the ability to output alias free data for maximum data reliability. Its advanced trigger model and high speed data streaming capability will allow users to capture all critical data.
TEMPERATURE MONITOR
The RX0224 can monitor its own internal temperature and airflow and provide over-temperature warning and temperature readings over Ethernet interfaces.
SCALABLE FOR HIGH-SPEED SYNCHRONIZED DATA ACQUISITION
The VTI RX0224 supports easy integration and synchronization of multiple devices through the IEEE-1588 synchronization standard. Multiple instruments can be easily distributed extremely close to the measurement points of interest reducing the run length of analog cable, minimizing errors induced by noisy environments. All measurement data is returned with IEEE-1588 timestamp values with typical accuracies of <100 ns ensuring that acquired data is tightly correlated across the test article.
The precision timing sources can not only be used to synchronize modules within a single instrument, but can also be used to synchronize data across multiple instruments in a distributed data acquisition system. When multiple instruments are connected on a local network, the instrument with the most accurate clock source will automatically become the master, and other instruments will derive the clock from the master – simplifying data synchronization across multiple units.
