Oscilloscope

An oscilloscope, wherein the oscilloscope has N sampling channels and the oscilloscope comprises:

• a first data processing unit configured to send a first synchronization signal to a first multi-output unit;
• the first multi-output unit configured to output a second synchronization signal to the N sampling channels, respectively, according to the first synchronization signal, wherein N is an integer greater than or equal to 2;
• an analog-to-digital conversion unit and a second data processing unit corresponding to each of the N sampling channels, wherein the analog-to-digital conversion unit is configured to perform signal sampling to determine first sampled data, and synchronously transmit the first sampled data to the second data processing unit of a sampling channel to which the analog-to-digital conversion unit belongs, according to the second synchronization signal;
• and the second data processing unit is configured to process the received first sampled data and send second sampled data obtained by processing the first sampled data to the first data processing unit;
• and
• a second multi-output unit configured to output a third synchronization signal to second data processing units respectively corresponding to the N sampling channels and the first data processing unit, respectively,
• wherein the third synchronization signal is configured to synchronize a frame clock of a data frame corresponding to the second sampled data transmitted between the second data processing unit and the first data processing unit.
