Displays signal voltage against time to show a waveform shape and provides a veriety of waveform measurement and analysis capabilities (with additional software).
Digital Multimeter (DMM) measure DC and AC singals. Measurements include voltage, current, resistance, capacitance and frequency.
DAQ measures electrical and physical properites over times to generate data that can be analyzed using a computer. A sensor or transducer can be used to convert data from physical properties to electrical signals.
A signal generator provides a clean signal which can be used as a local oscillator (LO), a stumulus signal, as an interference source, and more.
