100MHz Digital Storage Oscilloscope (DSO)
A 100 MHz digital storage oscilloscope (DSO) is an advanced electronic test and measurement instrument capable of measuring and displaying various electrical and electronic characteristics of a signal. A DSO uses digital technology to acquire, process, and display waveforms. This makes it more versatile and capable of performing various measurements and analysis functions.
The 100 MHz refers to the bandwidth of the oscilloscope and means it can accurately capture and display signals with frequencies up to 100 MHz.
Key Measurements a DSO can make include:
- Voltage Measurement - can measure the amplitude or voltage level of a signal. You can determine peak-to-peak voltage, RMS (root mean square) voltage, or measure voltage at specific points on the waveform.
- Time Measurements - parameters such as the period, frequency, rise time, fall time, and pulse width of a signal.
- Phase Measurement – allows you to measure the phase difference between two or more waveforms. This is useful for analysing the timing relationships in complex systems.
- Frequency Analysis - can show the frequency components of a signal, helping to identify harmonics or frequency content in a waveform.
- Pulse and Edge Measurements - can capture pulse parameters like duty cycle, pulse width, and time between rising or falling edges.
- Jitter Analysis - which is the variation in the timing of signal edges.
- Distortion and Noise Analysis - can help in detecting and quantifying signal distortions and noise levels in waveforms.
- Serial Data Analysis - some DSOs have specific features for analysing and decoding serial data protocols like SPI, I2C, UART, and CAN.
- Advanced Triggering - offer a wide range of triggering options that help capture specific events or conditions in a signal for analysis.
- Math Operations - allowing you to add, subtract, multiply, or divide signals for analysis.
These are just some of the many measurements and analyses that digital storage oscilloscopes can perform. The specific measurements and analyses will depend on the model and capabilities of the DSO, and they are widely used in fields such as electronics, telecommunications, engineering, and research to understand and troubleshoot electrical and electronic systems.
