RS Components has introduced a low-cost, next-generation data-acquisition system offering the ability to quickly and dynamically sample more signals simultaneously.


Manufactured by Keysight Technologies the new DAQ973A data-acquisition system is a three-slot modular mainframe unit that comes with a selection of nine plug-in modules and provides a sampling rate of 800kSa/s. The company has re-used its measurement engine from its high-end test and measurement equipment inside the device to provide proven measurement performance, modular flexibility and universal inputs with built-in signal conditioning. The unit also provides a built-in 6½-digit (22-bit) digital multimeter with a DCV accuracy of 0.003%. Similar to the existing DAQ970A system, this new system arrives with extra GPIB connectivity.


Key features of the unit comprise a scan rate of up to 450 channels, giving speed and accuracy to deliver fast results; up to 120 channels per system; and a large selection of switch, RF and control plug-in modules, including a new four-channel simultaneous sampling digitiser. The unit can additionally measure and convert 12 different input signals, comprising temperature with a thermocouple, RTDs and thermistor; DC/AC volts; two- and four-wire resistance networks; frequency and period; and DC/AC current and capacitance.


Typical users are expected to be test engineers and technicians over a broad variety of professional and industrial applications, including R&D and bench-testing prototypes; design verification for environmental, durability and regulatory applications; in automated testing and process monitoring in manufacturing environments; as well as monitoring and troubleshooting in service and maintenance roles. However, the unit is also anticipated to be employed in educational establishments.
