Agilent Technologies has expanded its U1071A line of Acqiris two-channel, high-speed PCI digitizers and the product line now includes models that offer additional functionality that can be combined with the series’ large memory capacity of up to 256 MSamples.
The 200 MHz (U1071A-004) version features a sampling rate of up to 1 GS/s as well as a multimodule synchronization option, which can be used to create tailored, high-performance systems. When more than two data-acquisition channels are required, up to three digitizers can be synchronized using the 2 GHz auto-synchronization bus. This distributes both the clock and trigger signals among the digitizers in the system.
It allows any digitizer to generate the trigger, while the central digitizer acts as the common synchronous clock source. With up to six synchronous acquisition channels, applications requiring high-speed measurement around 3D space, or 3-phase electricity can now be integrated into a single desktop PC.
The U1071A power consumption is less than 15 W. Designed in a standard short PCI card format (170 mm x 107 mm x 16 mm), the two-channel digitizer series can provide up to 1 GS/s simultaneous sampling rates on each input or, through channel interleaving, up to 2 GS/s on either channel. Analog bandwidths available are now 1 GHz, 500 MHz and 200 MHz. All versions now feature commutable 50 ohm or 1 Mohm input impedances on the input channel that allow easy integration of the digitizer for applications such as production test in automotive and semiconductor industries, requiring high bandwidth and high sample rate.
With the optional simultaneous acquisition and readout mode, the on-board memory is separated into multiple buffers.
As data is acquired into one buffer, another can be read out through the 32-bit/64 MHz PCI bus at up to 250 MB/s. In applications, such as point scan imaging, where the total data rate of the acquisition is below the PCI data bandwidth, the U1071A can acquire continuously, missing zero events.
