Ageilent expands digitiser range

Agilent Technologies has announced the expansion of its U1071A line of Acqiris two-channel, high-speed PCI digitisers.

The product line now includes models that offer additional functionality that can be combined with the existing large memory capacity of up to 256 MSamples.

These digitisers are suitable for use in a wider range of applications, including automated test equipment for production test and validation.

The new 200MHz (U1071A-004) version features a sampling rate of up to 1GS/s and a multimodule synchronisation option, which can be used to create tailored, high-performance systems.

When more than two data-acquisition channels are required, up to three digitisers can be synchronised using the 2GHz auto-synchronisation bus.

This distributes both the clock and trigger signals among the digitisers in the system.

It allows any digitiser to generate the trigger, while the central digitiser acts as the common synchronous clock source.

With up to six synchronous acquisition channels, applications requiring high-speed measurement around 3D space, or three-phase electricity can now be integrated into a single desktop PC.

The U1071A digitiser's compact size and power consumption of less than 15W belies its powerful digitising capabilities.

Designed in a standard short PCI card format (170mm x 107mm x 16mm), the two-channel digitiser series can provide up to 1GS/s simultaneous sampling rates on each input or, through channel interleaving, up to 2GS/s on either channel.

Analogue bandwidths available are 1GHz, 500MHz and 200MHz.

All versions now feature commutable 50ohm or 1 Mohm input impedances on the input channel that allow easy integration of the digitiser for applications 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/64MHz PCI bus at up to 250MB/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.

Where large single block acquisitions are required, new memory options extend the 256 kSample acquisition memory to 64, 128 or 256 MSamples.

In a sequence mode with maximum memory, up to 64,000 segments can be acquired.

Or as a single-shot acquisition, 128ms of data can be acquired at the full 2GS/s sampling rate of the digitiser.
