Analog and digital oscilloscope in the observation of the details of the waveform, which has the advantage?
1.Which is more advantageous, analog or digital oscilloscope, in looking at the details of the waveform (e.g., looking at parasitic waveforms of less than 1% at zero and peak crossing)?
2. Digital oscilloscope generally provides online display of root mean square value, its accuracy is generally what?
Answer: 1) observe parasitic waveform of less than 1%. The observation accuracy is not very good either in analog oscilloscope or digital oscilloscope. The vertical accuracy of the analog oscilloscope may not be higher than that of the digital oscilloscope. For example, the vertical accuracy of the analog oscilloscope with a certain 500MHz bandwidth is ±3%, which is not more advantageous than that of the digital oscilloscope (usually the accuracy is 1-2%). Moreover, the automatic measurement function of the digital oscilloscope is more accurate than the manual measurement of the analog oscilloscope for details.
For the analog front end, main performance index of oscilloscope
The simulation bandwidth, including the amplitude-frequency response characteristics to the measured signal, is presented as the rise time index and the overshoot performance index in the time domain;
Dynamic range of input signal amplitude (range from minimum vertical sensitivity to maximum vertical sensitivity for non-digital processing);
Initial error characteristics and temperature drift characteristics of dc gain accuracy and offset accuracy;
Input impedance characteristics (parasitic capacitance of resistance in parallel) affect the effect on the circuit under test with or without a probe.
