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.
The development of oscilloscope probe
In the past 50 years, the interface design of various oscilloscope probes has been evolving continuously to meet the requirements of increased instrument bandwidth speed and measurement performance. In the earliest days, banana plugs and UHF connectors were commonly used. In the 1960s, the common BNC connector became the common probe interface type because BNC was smaller and more frequent.
Later, some manufacturers put forward the common workarounds, BNC type probe interface design in the use of the BNC connector at the same time, additional provides a simulation code detection scale coefficients of stitching, as part of the mechanical and electrical interface design, which makes the oscilloscope is compatible with automatic detection and change the oscilloscope display of vertical attenuation range.
Requirements for oscilloscope current probe
Wide frequency range: from dc to tens or even hundreds of megabytes.
The range is large: from milliampere to kiloampere.
Small size: with the improvement of integration and the increase of signal frequency, the external size of components is getting smaller and shorter and pins are getting shorter and shorter. Easy operation and high accuracy.
