About Us and What We Do
We make xDAP systems and DAP boards, and every one we make has an onboard processor that runs DAPL, a multitasking real-time operating system optimized for data acquisition and control applications. A user normally controls DAPL through Windows2, either locally or over a network. Every standard DAP model in current production also will run under Linux.
DAPL makes it easy to configure an xDAP system or DAP board for high-performance applications. The onboard operating system supports over 100 easy-to-use commands optimized for data acquisition and control. A complete application can require as few as six or seven commands out of the many available. Command categories include

Many people want to know that, even if their system starts with only a few channels, they can expand it at any time with only a few simple steps. DAPL takes care of all the software details associated with expansion, so software on the PC – LabVIEW, VEE, VB or C programs or whatever – need address nothing more complicated than a higher logical channel count. DAPL also supports multiple DAPs in one PC, and enables DAPcell software servers to support multiple PCs in a single synchronized data acquisition system.
A system starts with an xDAP that connects to a USB port or a DAP board that plugs into a PCI slot. A channel architecture based on Eurocards – plug-in hardware that mounts in industry-standard 19-inch racks – provides expansion, termination, and other functions that greatly extend the reach of even a single DAP.
Whenever you digitize real-world frequencies higher than half the sampling rate, you corrupt the data. Samples of these higher frequencies appear in any subsequent analysis only as lower frequency aliases. And by that stage you can do nothing – nothing at all – to correct the problem. So unless you know for sure that the signal you measure contains none of these higher frequencies at energy levels that your sensors can detect, you have to deal with the issue up front.
Microstar Laboratories provides two solutions to this problem: one in the form of a specialized DAP for high-frequency applications, and the other – with lower cutoff frequencies – as a Eurocard-format expansion board for all other DAPs.3
We take support very seriously. Take a look at our Product Life Cycle pages – especially if you are an industrial customer. After three decades of providing application engineering support, we have become skilled at finding out exactly what a customer needs and at working with each customer to come up with a system that performs as required. We look forward to doing that for you. Check us out, give us a call, and tell us what you want to do. In the US, use our toll-free line: 1-888-MSTARLABS (678-2752). Outside the US, contact one of our international distributors or email our sales staff.
