A 70MHz digital storage oscilloscope (DSO) works by converting analog electrical signals into a digital format, storing the waveform data in memory, and displaying it on a screen. The 70MHz bandwidth means it can accurately measure signals up to 70MHz. Key functions include real-time signal capture, storage, automatic measurements, and advanced analysis like the Fast Fourier Transform (FFT).
Working principle
Signal reception: The oscilloscope receives an analog electrical signal through its input channels.
Signal conditioning: The signal is amplified and attenuated to condition it for the next stage.
Analog-to-digital conversion: An Analog-to-Digital Converter (ADC) samples the analog signal at a high rate (e.g., 1 GS/s) and converts it into a series of digital data points.
