Educational Scope/Logger

Saelig Company Inc.'s USB DrDAQ is a combination scope/data-logger/IO board with 15 I/Ochannels. Software provided with the unit provides 100kHz-bandwidthoscilloscope and datalogger, with extra input and output capabilities straightout of the box. Builtinto the USB DrDAQ are a microphone, light sensor, RGB LED, oscilloscope andresistance inputs, 4 digital I/O ports, 3 sensor ports, a pH/redox sensor inputand a signal generator output. The unit is powered from the USB port so thereis no need for an external power supply. USB DrDAQ samples at 1MSa/s and can beused as a single-channel 8-bit 100kHz oscilloscope or spectrum analyzer withthe ability to measure voltages up to A plus or minus 10V.

USB DrDAQ's 10-bit D/A outputfeatures a 10-bit signal generator - a standard function generator, but also anarbitrary waveform generator (AWG), so customized waveforms can be created. AnRGB 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-widthmodulation) 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 intoa wide variety of applications from education to research for signals at audiofrequencies and beyond. It is supplied with a free Windows Software DevelopmentKit (SDK) with fully documented function calls to control all aspects of thedevice, so it can be integrated into other programs in C, C++, Microsoft Exceland National Instruments LabVIEW.
