The most advanced USB counter/timers we’ve seen

Measuring time-related data and counting events are basic to countless data acquisition applications, and they often fulfil critical timing functions as components of complex measurement systems. They’re simple in concept and specific in function, but essential in so many products and systems today.

Our friends at Measurement Computing, those developers of DAQ devices that match the best in industry in everything except price, have just come up with a couple of USB counter/timers with just about the most advanced functionality we’ve ever seen in such devices, yet they’re surprisingly inexpensive. High-level input modes include totalise, period measurement, pulse-width measurement, and timing measurement. Timer output channels can operate continuously or for a specified pulse count, with duty cycle and period changeable on the fly. Counter and digital channels can also be scanned synchronously. Flexible edge, level, direction and debounce settings allow the counters to adapt optimally to user signals.

You can choose between models with 4 or 8 counter I/Os. They offer high-speed pulse counting up to 48 MHz input frequency. Resolution is programmable up to 64 bits per counter, with an aggregate scan rate of 8 MB/sec. Four independent PWM timer outputs and 8 digital I/O are also provided.

Sound like they’re likely to meet your needs? Check them out here.

Popular USB DAQ devices get OEM makeover

Measurement Computing’s USB-1208, 1408 and 1608 modules are among our most popular data acquisition devices, offering up to 500 kS/s sampling, eight or 16 digital I/Os, and up to two analogue outputs. They’re fast, reliable and low cost, and as a result, there’s been a clamour from OEM and embedded customers for bare-board versions.

Now we’re happy to announce that Measurement Computing has released board-only versions of the USB-1208FS, 1408FS and 1608FS devices, as well as the high-speed USB-1608G, GX and GX-2AO products. In all of these, header connectors replace screw terminals to make the boards easy to integrate into OEM applications.

A trio of new DAQ modules for 2014

Always looking ahead and developing new products to fill emerging DAQ needs, market-driven Measurement Computing has launched a new ultra high-speed simultaneous sampling board, plus two new additions to the USB-200 Series of low-cost USB DAQ devices in the last month alone! As usual, all modules come with TracerDAQ® software for acquiring and displaying data and generating analogue signals, along with comprehensive support for Visual Studio® and Visual Studio® .NET, DASYLab®, and NI LabVIEW™.

The new USB-2020 features two analogue input channels with multiple input ranges up to ±10V and can sample data from both channels at an overall rate of 40 MS/s to the onboard memory, or continuously stream data to a host computer at up to 8 MS/s. The small, board-only design makes the USB-2020 ideal for OEM and embedded applications. At just £875*, the USB-2020 is unmatched in the industry for ultra high-speed USB DAQ. Click here to find out more and buy online.

The USB-202 and USB-205 feature sample rates up to 500 kS/s, eight 12-bit analogue inputs, two analogue outputs, eight digital I/O and one counter input. OEM versions of both boards are also available and feature header connectors instead of screw terminals.

New Script module means more flexibility for DASYLab users

Want to know which new feature stands out in the latest version 13 release of DASYLab – the easy-to-use software for configuring and controlling custom DAQ and analysis applications? If she had to choose from the extensive enhancements, CJ Butler, DASYLab Product Marketing Manager at Measurement Computing, believes the new Script module is the most important, most useful new addition to DASYLab’s toolset.

She said, “The script module addresses a number of instances where DASYLab functions don’t quite do what’s required or a new driver, computation or file type is needed. For example, several years ago, one of our customers needed a very specific, very proprietary computation and so they hired a C programmer to create a module for them using the Extension toolkit. Now with the introduction of the new Script module, it’s very likely they would have been able to use the Python script language to create the module themselves. It would have been faster, cheaper and could have been done in-house. These guys already use Python in a number of other areas. This customer is now looking at the Script module and Python to customise a PID function.”

She goes on to say, “What kinds of things will you be able to do with Python? I wrote a driver as part of the learning and testing process. I had a serial port device that was too complex for the RS232 module, and provided ActiveX/Com objects for developers. It was pretty easy to set up a module that found and initialised the device, programmed it, and then acquired all available data from it at 20-30 samples per second. MeasX has done a number of drivers using the Script functions and the DASYLab IVI modules are all created using the Script functions.”

CJ then tells us about an ongoing project. She explains, “I’ve been working on two Script modules. The first is a supplement for customers with worksheets that use the DDE Out module to send data to Microsoft Excel. It looks for and opens the target Excel workbook before the measurement starts, so that it is ready for the DDE Out. The second takes the thought a step further. Using the Example from the Help, I added the workbook logic that I’d done for the first, and created a Script that would open or create an Excel workbook, create a new sheet and then log data to it.”

The new Script module looks set to open up DASYLab usage for both end users and resellers by enabling them to enhance and extend DASYLab beyond the out-of-the-box release. The ability to export and package it as a standard module secures their intellectual property and allows them to sell or share it without the code. The possibilities are immense, and DASYLab’s developers are really hoping users will take advantage of this new feature!

DASYLab customers who want to share (or sell) their new scripts or modules on the DASYLAB website should email info@dasylab.com.

Disclaimer – the Script module cannot do everything. If you need a new Display module, for example, you will still need to use the Extension Toolkit.
