Bellevue, WA, November 3, 2011 -- Microstar Laboratories, Inc. has announced the release of the xDAP 7420 data acquisition system. xDAP 7420 adds a high-speed sampling mode to the capabilities of the xDAP line, with a sample rate double that of its predecessor, xDAP 7410. This system is CE compliant, making it suitable for applications in the European Union and worldwide. It is also compatible with both North American and European power standards, requiring no switching or reconfiguration. It retains all of the capabilities of xDAP 7410 and, other than the higher rates when you need them, all performance specifications are the same.

High-Performance Simultaneous Sampling

Like xDAP 7410, each xDAP 7420 provides eight parallel 16-bit analog-to-digital converter channels. These are clocked simultaneously and run at configurable rates of up to two million samples per second. The aggregate sample transfer rate limit is eight million samples per second, with transfers to the host continuously sustainable across the USB interface at this rate. For host applications that cannot sustain this pace, there is enough local buffer memory to record a full minute of activity without any concurrent transfers.

xDAP 7420 features an embedded 2.0 GHz Celeron processor that manages all of the real-time aspects of acquisition hardware management and data buffering. All of this, plus higher level data pre-processing and transfer management, is controlled by the embedded DAPL real-time operating system that runs on every Data Acquisition Processor (DAP) system. On the host side, xDAP 7420 application software uses the same "channel architecture" driver and server software, provided at no extra cost – it is the same interface software that all of the other DAP products use as well.

Examining the numbers more closely, the two million samples per second rate and eight million samples per second composite transfer limit mean that a maximum of four channels can be captured at the absolute maximum rate limit. If you do not need all four channels at these rates, the unique "dual mode sampling" capabilities of xDAP 7420 allow you to use the extra capacity for other channels at a reduced rate: for example, two channels can be captured at the maximum two million samples per second each, while at the same time, 12 channels are captured at 250 thousand samples per second each.

Added Features

xDAP 7420 remains compatible with all previous DAPL 3000 configuration scripts – as long as they do not specify hardware channels beyond the range that xDAP 7420 supports. The onboard intelligence that runs within the embedded DAPL 3000 system frees you from the real-time delays and uncertainties present in your host operating systems. A USB interface connects xDAP 7420 to your local workstation or laptop, and that can control the processing directly, or enable remote networked access. The DAPIO programming interface allows you to manage configurations and data transfers from your favorite programming languages and environments, such as DAPstudio, C++, Visual Basic, or LabVIEW. DAPstudio, from Microstar Laboratories, assists you in building downloaded configuration scripts, providing a means for independently validating and testing the embedded side of your applications – in some cases, providing everything you need for a complete measurement application. The DAPIO interface can support Windows 7 64-bit applications either in 32-bit compatibility or 64-bit native modes.

Conclusion and Next Step

While offering a sampling rate that doubles the rate of previous products, with no loss of data quality, the CE-qualified xDAP 7420 extends the xDAP family to new application possibilities. The new product remains compatible with the DAPIO programming API, with support for operating systems from Windows XP through Windows 7, including the 64-bit edition. It also remains compatible with DAPstudio software from Microstar Laboratories, for independently configuring the embedded processing. The DAPtools Basic software package, including a demo version of the DAPstudio software, is provided with every system at no charge. Download an evaluation copy.

Editorial Overview:

Microstar Laboratories, Inc. has announced the release of the xDAP 7420 data acquisition system. xDAP 7420 is CE compliant, making it suitable for applications in the European Union and worldwide. It adds an extended acquisition rate of two million samples per second on each channel, at double the rate supported by its predecessor, xDAP 7410, while continuing to support the eight million samples per second sustained transfers to an application on a PC-workstation or laptop host. xDAP 7420 is available now.
