Determine the bandwidth of the test signal to select the oscilloscope
Bandwidth is generally defined as the frequency when the amplitude of sinusoidal input signal attenuates to -3db, that is, 70.7% of the amplitude. The bandwidth determines the basic measuring ability of oscilloscope to signal. If there is not enough bandwidth, the oscilloscope will not be able to measure the high frequency signal, the amplitude will be distorted, the edge will disappear, the detail data will be lost;Without sufficient bandwidth, all the features of the resulting signal, including ringing and ringing, are meaningless.
An effective rule of thumb for determining the bandwidth of an oscilloscope you need -- the "5x rule of thumb" : multiply the highest frequency component of the signal you are measuring by 5, so that the measurement results are more than 2% accurate.
In some applications, you do not know the bandwidth of the signal of interest to you, but you do know its maximum rise time, at which time the frequency response calculates the associated bandwidth and rise time of the instrument using the following formula: Bw=0.35/maximum rise time of signal.
There are two types of digital oscilloscope bandwidth: repeat (or equivalent time) bandwidth and real-time (or single time) bandwidth. Repeat bandwidth only applies to repeated signals, showing sampling from multiple signal acquisition periods. Real-time bandwidth is the highest frequency that can be captured in the single sampling of oscilloscope, and it is more important when the captured events are not frequent or transient signals. Real-time bandwidth is closely related to the sampling rate.
The higher the bandwidth, the better, but higher bandwidth often means higher prices, so choose the frequency component of the signal you're looking at on a budget.
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.
