How Does Electronic Measurement Equipment Function?
Electronic measurement equipment functions by measuring and analyzing electrical signals and properties of materials. The specific function of an electronic measurement instrument will depend on its type and the measurements it is designed to make.
Generally, electronic measurement equipment converts electrical signals into a digital format that the instrument can analyze and process. The electrical signal is typically captured by a probe, sensor, or input device, which converts the electrical signal into a voltage that is proportional to the signal’s amplitude.
The instrument then processes the voltage signal by amplifying, filtering, or modifying it to make it suitable for measurement. The signal is then digitized by an analog-to-digital converter (ADC), which converts the voltage signal into a digital format that can be analyzed and processed by the instrument’s software.
Once the signal has been digitized, the instrument’s software can perform various types of analysis and measurement. For example, an oscilloscope can display the signal waveform in real time and provide measurements of the signal’s amplitude, frequency, and other properties. A spectrum analyzer can display the signal’s frequency spectrum and provide measurements of the signal’s spectral content and noise sources.
Functions of Electronic Measurement Equipment
Here are some of the key functions performed by electronic measurement equipment:
- Signal capture: Electronic measurement equipment captures electrical signals from different sources, including sensors, probes, and input devices.
- Signal conditioning: Signals captured by electronic measurement equipment often need to be conditioned to be suitable for measurement. This involves amplifying, filtering, or modifying the signal in some way to remove noise and improve signal quality.
- Signal digitization: The conditioned signal is then digitized using an analog-to-digital converter (ADC). This involves converting the analog voltage signal into a digital format that can be analyzed and processed by the instrument’s software.
- Signal analysis: Electronic measurement equipment performs various types of signal analysis, depending on the type of instrument and measurement being made. For example, an oscilloscope displays signal waveforms in real time and provides measurements of the signal’s amplitude, frequency, and other properties. A spectrum analyzer displays the signal’s frequency spectrum and provides measurements of the signal’s spectral content and noise sources.
- Measurement calculations: Electronic measurement equipment often perform complex calculations to determine the specific measurement. For example, a network analyzer may perform complex calculations to determine a circuit or device’s reflection coefficient, impedance, and other properties.
- Data storage and analysis: Electronic measurement equipment often has built-in data storage and analysis capabilities that allow users to store and analyze measurement data over time. This is particularly useful for applications that require long-term monitoring and analysis of electrical signals and properties.
