Saelig Company Inc.'s USB DrDAQ is a combination scope/data-logger/IO board with 15 I/O
channels. Software provided with the unit provides 100kHz-bandwidth
oscilloscope and datalogger, with extra input and output capabilities straight
out of the box. Built
into the USB DrDAQ are a microphone, light sensor, RGB LED, oscilloscope and
resistance inputs, 4 digital I/O ports, 3 sensor ports, a pH/redox sensor input
and a signal generator output. The unit is powered from the USB port so there
is no need for an external power supply. USB DrDAQ samples at 1MSa/s and can be
used as a single-channel 8-bit 100kHz oscilloscope or spectrum analyzer with
the ability to measure voltages up to Â±10V.
USB DrDAQ's 10-bit D/A output
features a 10-bit signal generator - a standard function generator, but also an
arbitrary waveform generator (AWG), so customized waveforms can be created. An
RGB LED can be used to display any color for a variety of indicator purposes.
Two of the I/O ports can be used as pulse counting inputs, or PWM (pulse-width
modulation) outputs. The sensor ports can be used with a range of temperature,
humidity and oxygen sensors, or with custom sensors built by the user.
USB DrDAQ will find its way into
a wide variety of applications from education to research for signals at audio
frequencies and beyond. It is supplied with a free Windows Software Development
Kit (SDK) with fully documented function calls to control all aspects of the
device, so it can be integrated into other programs in C, C++, Microsoft Excel
and National Instruments LabVIEW.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
