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.
Analog and digital oscilloscope in the observation of the details of the waveform, which has the advantage?
1.Which is more advantageous, analog or digital oscilloscope, in looking at the details of the waveform (e.g., looking at parasitic waveforms of less than 1% at zero and peak crossing)?
2. Digital oscilloscope generally provides online display of root mean square value, its accuracy is generally what?
Answer: 1) observe parasitic waveform of less than 1%. The observation accuracy is not very good either in analog oscilloscope or digital oscilloscope. The vertical accuracy of the analog oscilloscope may not be higher than that of the digital oscilloscope. For example, the vertical accuracy of the analog oscilloscope with a certain 500MHz bandwidth is ±3%, which is not more advantageous than that of the digital oscilloscope (usually the accuracy is 1-2%). Moreover, the automatic measurement function of the digital oscilloscope is more accurate than the manual measurement of the analog oscilloscope for details.
