A signal processing apparatus and method, and a digital oscilloscope are provided. The signal processing apparatus is configured to output one of two target signals according to a trigger signal and a trigger level. The signal processing apparatus includes a trigger comparison unit, a trigger display unit, and a controller. The trigger comparison unit is configured to extract a low-frequency component signal from the trigger signal. The controller is electrically connected to the trigger comparison unit and is configured to generate a trigger comparison signal according to a relationship between the low-frequency component signal and the trigger signal, and output a target signal obtained based on the trigger comparison signal according to a preset rule. The trigger display unit is electrically connected to the controller and is configured to receive and display the target signal on a target interactive interface.

Signal processing apparatus and method, and digital oscilloscope

Disclosed are a device synchronization calibration method and apparatus, a device, and a storage medium. The method includes that timestamp synchronization deviations between all two devices among at least two devices is acquired, that it is determined whether each of the timestamp synchronization deviations between the all two devices is a set value, and that a synchronization calibration instruction is generated in response to a determination result that any timestamp synchronization deviation is not the set value. The synchronization calibration instruction is used for performing synchronization calibration for two devices corresponding to any timestamp synchronization deviation.

Device synchronous calibration method and apparatus, devices, and storage medium

Provided are an automatic trigger type identification method and device and an oscilloscope, which belong to the field of oscilloscopes. The method includes analyzing characteristic parameter data of a to-be-triggered signal. The characteristic parameter data comprises at least one of bus protocol matching information or variation information of at least one characteristic parameter. In this way, a trigger type capable of stably triggering the to-be-triggered signal can be obtained for user selection or automatic selection for trigger.
