Signal reconstruction method adopted by oscilloscope
How to calculate the sampling rate? The calculation method depends on the waveform type measured and the signal reconstruction method adopted by oscilloscope, such as example sinusoidal insertion method, vector insertion method, etc. To reproduce the signal accurately and avoid confusion, the Nyquist theorem states that the sampling rate of the signal must be no less than twice its highest frequency component. However, the premise of this theorem is based on signals of infinite length of time and continuous period. Since oscilloscopes cannot provide a record length of infinite time, and low-frequency disturbances are by definition discontinuous and not periodic, sampling rates of twice the highest frequency components are usually insufficient.
In fact, the accurate reproduction of the signal depends on its sampling rate and the interpolation method of signal sampling point gap, namely waveform reconstruction.Some oscilloscopes provide the operator with the following options: sinusoidal interpolation for measuring sinusoidal signals, and linear interpolation for measuring rectangular waves, pulses, and other signal types.
A useful rule of thumb for comparing sample rates and signal bandwidths: if the oscilloscope you are looking at has interpolation (filtered to regenerate between sample points), the ratio (sample rate/signal bandwidths) should be at least 4∶1.Without sine interpolation, the ratio of 10∶1 should be adopted.
Analog technique that determines the performance height of an oscilloscope
Although the oscilloscope is not instrument on the top of the hardware requirements, given the oscilloscope is the most familiar with many engineers is one of the biggest single instrument of test equipment market segment, so we interviewed in the world to do the oscilloscope bandwidth GHz level several representative, from the analysis on the oscilloscope hardware, with everyone together to understand the core of the oscilloscope design unit.
Bandwidth, sampling rate and storage depth, is the most intuitive decision an oscilloscope market value of the three features, including bandwidth can reflect the performance of the oscilloscope is the most obvious indicators, sampling rate values and bandwidth have been linked, while the two numerical oscilloscope is directly related to the final price, its value is basic it is decided by simulation unit of hardware performance.
