Agilent Technologies has introduced a series of multifunction data acquisition (DAQ) modules and instrument chassis that offer increased bandwidth for multiple I/O operations coupled with ease of connectivity and hot-swappable connections.

This, together with the DAQ devices' high sampling rate of up to 3MSa/s for a single channel, enables fast and easy instrument setup and quality data acquisition.
"As data acquisition systems become more complex with multi-configuration and multi-vendor components and instruments, Agilent saw the need to reduce this complexity through easy-to-use DAQ modules and non proprietary standard USB interfaces," says Andrew Lees, internal sales team leader at Agilent distributor Concilium Technologies.
"Plus, if you combine the ability to use any module standalone with a PC and then combine it into a card cage for larger acquisition requirements, users undoubtedly benefit from enhanced flexibility and lower cost ."
Today, DAQs are commonly used to perform measurement, monitoring, control or simulation of real-world signals such as temperature, pressure, vibration and strain.
"In light of industry as well as home technologies' increasing complexity and speed, more emphasis is placed on not only collecting data from sensors but collecting it fast enough, for long enough, to study transient phenomena that are likely to influence the performance of not only the device itself but other devices in the same environment," Lees says.
DAQ devices, for example, can be applied in various industry-specific tests such as everyday electrical appliances.  One example would be a standby mode test where measurements like voltage and current are taken and verified over a period of time.
Explains Lees: "The critical parameter would be the glitches, which occur during these measurements. Thus, the recommended measuring instruments should have high sampling rate and deep memory.
"In the case of Agilent's USB DAQ the voltage is measured directly while the current is measured using a current transducer. The current transducer will then convert the current into a voltage signal and send this to the DAQ. The data will be displayed and post- analysed on the PC."
