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.
Microprocessor selection of digital oscilloscope
In addition, omap-l138 is floating, fixed-point compatible with DSP, and can use hardware to complete floating point operation, which can be completed in a single cycle. This advantage is particularly prominent in the implementation of high-precision complex algorithms, providing a guarantee for real-time processing of complex algorithms.Omap-l138 can also be compatible with C6748 DSP to achieve pin - to - pin compatibility
