Sampling rate and adc of oscilloscope
Among the three performance indexes of the oscilloscope, the analog front end determines the bandwidth, and the analog-to-digital converter (ADC) is the most important link affecting the sampling rate. ADC is the core device of the digital oscilloscope, among which the most critical indexes are the sampling rate and the effective ADC bits. The sampling rate of ADC directly determines the digital bandwidth of oscilloscope, that is, how high frequency signal can be effectively collected and displayed.
The sampling rate of A/D converter cannot be increased indefinitely. R&S has the leading single-core 10Gs/s sampling rate A/D converter in the oscilloscope market.In order to achieve A higher sampling rate, many companies have adopted the interleave sampling technology, that is, multiple low-speed A/D parallel combination of multiple high-speed multi-core A/D.The problem with this technique is the phase error of the signal.To correct this error, most oscilloscope manufacturers use DSP correction technology.However, it takes time to correct DSP, and this correction reduces the waveform acquisition rate of oscilloscope.
Digital oscilloscope generally provides online display of root mean square value, its accuracy is generally what?
For oscilloscope amplitude measurement accuracy, many people use A/D digit to measure. In fact, it varies depending on the oscilloscope bandwidth you use, the actual sampling rate Settings, and so on. If the bandwidth is insufficient, the amplitude measurement error itself will be very large; if the bandwidth is sufficient, the sampling setting is very high, and the actual amplitude measurement precision is not as good as that of the sampling rate when the sampling rate is low (you may refer to the user's manual of the oscilloscope, which may give the actual effective digits of an oscilloscope at different sampling rates). In general, oscilloscope measurement amplitude, including root mean square value accuracy is often less than the multimeter, similarly, measuring frequency it is less than the frequency counter.
