Title:
TIME DELAY CALIBRATION APPARATUS, OSCILLOSCOPE, TIME DELAY CALIBRATION SYSTEM, AND TIME DELAY CALIBRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/193450
Kind Code:
A1
Abstract:
A time delay calibration apparatus (100), comprising: a source signal supply module (110), a source signal processing module (120) and a fan-out module (130), wherein the source signal supply module (110) is connected to the source signal processing module (120) and is used for providing a source signal for the source signal processing module (120); the source signal processing module (120) is used for generating a time delay calibration signal on the basis of the source signal and outputting the time delay calibration signal to the fan-out module (130); and the fan-out module (130) is used for performing fan-out processing on the time delay calibration signal, so as to obtain a plurality of paths of output signals, which are output to the outside of the time delay calibration apparatus (100). In this way, time delay calibration can be performed on a plurality of probes simultaneously, thereby facilitating a user operation and saving on the time delay calibration time; and compared with time delay calibration using an ordinary signal source, time delay calibration in the present application can better meet time delay calibration requirements, such that the accuracy of time delay calibration is improved. An oscilloscope comprising a time delay calibration apparatus, a time delay calibration system, and a time delay calibration method, which is applied to a time delay calibration apparatus, are provided.
