Problems solved by technology
The signal measuring instrument will capture multiple data involved in the signal switching, but the user cannot find the details of the signal switching from the waveform diagram displayed by the signal measuring instrument. Spend a lot of time triggering the signal to observe the waveform of the signal switching, and then study the details of the signal switching or the wrong operation of the signal measurement instrument

Embodiment Construction
[0013] Such as figure 1 Shown is an operating environment diagram of a preferred embodiment of the signal detection system of the present invention. The signal detection system 10 runs in a signal measuring instrument 1 , and the signal measuring instrument 1 is used for detecting a signal of an object under test 2 . In this embodiment, the signal measuring instrument 1 may be an oscilloscope, a spectrum analyzer and the like. This signal measuring instrument 1 is connected to a database 11, and this database 11 can be built in this signal measuring instrument 1, also can be externally connected to this signal measuring instrument 1 ( figure 1 It is shown that the database 11 is built into the signal measuring instrument 1). The database 11 is used to store test data when the signal measuring instrument 1 detects the signal of the object under test 2 . The signal measuring instrument 1 includes a display screen 12 for displaying a waveform obtained by the signal measuring i...

The invention provides a signal detection method. The method comprises the following steps: receiving an time interval for setting restore points set by a user; capturing all test data of an object to be measured by a current signal measurement instrument at set time interval when the signal measurement instrument measures a signal of the object to be measured, and establishing a folder; storing the captured test data in the established folder which is a restore point; and calling all test data in the folder which is established most recently when the signal measurement instrument is required to return to the restore point, and displaying all the test data on the display screen of the signal measurement instrument. The invention also provides a signal detection system. By the method and the system, the measurement result before misoperation can be returned at any time, so that repeated signal detection is avoided.
Description
technical field [0001] The present invention relates to a detection system and method, in particular to a signal detection system and method. Background technique [0002] Measuring the signal with a signal measuring instrument allows the user to see the waveform diagram of the signal. When the signal is switched, for example, the switching between reading data and writing data in the computer memory, etc. The signal measuring instrument will capture multiple data involved in the signal switching, but the user cannot find the details of the signal switching from the waveform diagram displayed by the signal measuring instrument. Spend a lot of time triggering the signal to observe the waveform of the signal switching, and then to study the details of the signal switching or the wrong operation of the signal measurement instrument. Contents of the invention [0003] In view of the above, it is necessary to provide a signal detection system that can return the signal measure...
