Configuring m file for ttl trg on the USB-2533

I am using the ttl trg on the USB-2533. This works poorly. We want the trigger to come in at 20 hz. It gives us between 7 and 10 hz. Is the specification 'HwDigital' correct? Is it possible to use the ttl trg at all? If not could you suggest some other tr

Hello - The start trigger feature on most of MCC’s DAQ devices is not self-rearming. It requires the user’s program to, after stopping the current scan, to call the “Scan” function again. The overhead to achieve this varies by model, and the overhead for the USB-25xx is higher than for the PCI-DAS16xx series. Unfortunately there is no way to improve this, short of running on a faster PC. The only alternative is to run a continuous scan (never stop the scan), sample your trigger signal on a spare channel, and the post-process the data with your own algorithm that decides which data to keep and which to throw away.

Summary
MATLAB® is a software environment for data acquisition, data analysis, and application development. MATLAB supports the data acquisition and analysis process along with interfacing with data acquisition devices and instruments, analyzing and visualizing the data. It also produces presentation-quality reports to share results with others.

MATLAB supports IOtech hardware by using the MATLAB Data Acquisition Toolbox. The Data Acquisition Toolbox enables MATLAB to control and acquire data from data acquisition equipment and allows measured data to be streamed and analyzed live into MATLAB. The data collected using test and measurement tools can be brought directly into the MATLAB workspace for fast and accurate data analysis, data manipulation, and pre- and post-processing.

Analysis on collected data is easy to perform with MATLAB, the Data Acquisition Toolbox and their built-in analysis functions. Some of these include peak, valley and zero finding, Fourier analysis, smoothing, interpolating, and extracting sections of data.
