The invention discloses a signal collecting device and a working method of the signal collecting device and relates to the technical field of electronic information, and the signal collecting device and the working method can effectively improve the sampling frequency of a multi-channel synchronous sampling device. The signal collecting device comprises a copying part and a collecting part, wherein one end of the copying part is connected with M channels to input signals, and the other end of the copying part is connected with the collecting part and used for copying the input signals in each of the M channels to be N channels of identical signals and for outputting the N channels of signals to the collecting part, wherein M is a natural number, and N is a natural number larger than one; the collecting part comprises M*N sampling units, and the M*N sampling units correspond to the M*N channels of signals output by the copying part to the collecting part respectively; the N sampling units in each channel are used for sampling the N channels of the input signals in turns so that the equivalent sampling frequency of each channel can be N times that of each sampling unit. The working method is suitable for various signal collecting devices.
Description
technical field [0001] The invention relates to the technical field of telecommunications, in particular to a signal acquisition device and a working method thereof. Background technique [0002] In the field of telecommunications technology, in order to understand the working status of equipment or process data, it is often necessary to sample or measure various signals (such as bus signals or other parallel signals). Since the number of various buses or parallel signals ranges from two to nearly a hundred, and the signal frequency is distributed between several thousand Hz to several GHz, a higher frequency multi-channel synchronous sampling device is often required to meet the requirements for sampling requirements for these bus signals or parallel signals. [0003] However, in actual situations, due to the limitation of the performance of the internal processing module of the signal acquisition equipment, it is not easy to increase the sampling frequency of the multi-ch...
