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.
Digital oscilloscope test accuracy
Any designer who chooses oscilloscope for parameter measurement will know its test accuracy through the product index to ensure enough tolerance error and measurement margin.Jitter testing is no exception. For example, the tekker TDS6804B oscilloscope indicates the precision and specifies the typical value of jitter measurement capability.Jitter measurement accuracy is affected by many factors, including timing stability of oscilloscope, sampling noise, instrument amplitude background noise and interpolation error.
Interpolation error is caused by linear interpolation between actual voltage samples.This error is less than 0.3ps RMS when measuring 100ps rise time signal and oscilloscope detects at 50% voltage threshold with 20GSa/s sampling rate.In many cases, this error can be improved by sine (X)/X sine interpolation in oscilloscope and other methods, such as making full use of the vertical dynamic range of oscilloscope, so that the input signal amplitude reaches the oscilloscope full scale.In most cases, the error for this reason is much smaller than for other error sources, and can be further reduced by using interpolation such as Sin(X)/X or Sinc.
