DrDAQ is a versatile instrument that connects to the USB port of any PC. Using the supplied PicoScope software it can be used as an oscilloscope, spectrum analyzer and signal generator.
Seismic waves form part of the UK National Curriculum (see below) and the seismometer provides an opportunity for experimental work using a data logger or oscilloscope.
