There are usually three methods of bandwidth for high - end oscilloscopes
One is the direct realization of preamplifier circuit;Second, DSP is used to stretch bandwidth;Third, digital bandwidth reuse.
According to tek, each of the three approaches has its own advantages. At present, preamplifier direct implementation and DSP stretch bandwidth technology are widely used in the market. From the perspective of use, the bandwidth of hardware implementation USES less digital technology, with high signal fidelity, more flexible in use, less restrictions, flatter frequency response and noise spectrum, support equivalent sampling and undersampling, and allow signal beyond the screen, but the cost is relatively high. In contrast, digital technology may cause fluctuation of frequency response or noise spectrum, with low effective bit at some frequencies. Meanwhile, digital technology requires real-time sampling, does not support under-sampling, and waveform distortion will occur when the signal goes beyond the screen, which has relatively high restrictions and higher requirements on users. But the bandwidth achieved by digital technology is relatively cheap due to the low cost of hardware, providing a cheap solution for users at the expense of some performance.In general, preamplifier technology and DSP provide different options for different customers.
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.
