Embodiment two, this application provides a kind of cache information sweep-out method for oscillograph, please refer to Fig. 2, step
Following S000~S100, is specifically described below.
S000, digital oscilloscope include multiple function modules, and a data cache module is provided respectively to each function module
To cache the data that the function module need to cache.The waveform that 151 stored waveform display module 131 of Wave data cache module generates
It is data cached；It is data cached that twilight sunset data cache module 152 stores the twilight sunset that twilight sunset display module 132 generates；Statistical data is slow
It is data cached that storing module 153 stores the statistics that statistical measurement module 133 generates；Test data cache module 154 stores pass/
The test that fail test modules 134 generate is data cached.
S100 responds total clearance order to remove the data cached.See that Fig. 1, function module 13 are controlled in response to removing
Total clearance order that unit 11 generates, the data cached in the cache module 15 that clears data.
In one embodiment, as shown in figure 3, step S100 removes data cached method in response to total clearance order includes
Following steps S110~S113.
S110 obtains total clearance order.Trigger architecture 111 will generate button trigger signal, instruction when being pressed by the user
Administrative unit 113 will receive the button trigger signal and be total clearance order by the signal identification.
In one embodiment, trigger mechanism 111 is set on the shell of the digital oscilloscope, for button, is stirred
Key or knob.

It can module.
In a specific implementation, instruction administrative unit 113 generates multiple sub- clearance orders according to total clearance order, and by this
A little clearance order is with waveform clearance order, twilight sunset clearance order, statistics clearance order and the specific command for testing clearance order
Format is respectively sent to waveform display module 131, twilight sunset display module 132, statistical measurement module 133 and pass/fail tests
Module 134 instructs each function module to start the data cached removing function of itself respectively.
S112 sends corresponding delete command.Each function module 13 after corresponding sub- clearance order in response to that will start
The data cached removing function of itself sends corresponding delete command to its data cache module.
In the present embodiment, waveform display module 131 is in response to waveform clearance order, to Wave data cache module 151
Wave data delete command is sent to remove Waveform caching data；Twilight sunset display module 132 in response to the twilight sunset clearance order,
It is data cached to remove twilight sunset that twilight sunset data-delete command is sent to twilight sunset data cache module 152；133 sound of statistical measurement module
Clearance order is counted described in Ying Yu, sends statistical data delete command to statistical data cache module 153 to remove statistics caching
Data；Pass/fail test modules 134 send to test data cache module 154 and test in response to the test clearance order
Data-delete command is data cached to remove test.
In one embodiment, above-mentioned each delete command is only used for deleting the caching number in corresponding data cache module
According to (i.e. data information), without deleting the configuration parameter (controlling information) in corresponding data cache module.
S113 after data cache module 15 receives corresponding delete command, will be deleted corresponding data cached.One
In specific implementation, Wave data cache module 151 deletes internal stored Waveform caching data, twilight sunset data cache module
The internal stored twilight sunset of 152 deletions is data cached, and statistical data cache module 153 deletes internal stored statistics caching number
According to the stored test in 154 inside of test data cache module is data cached.
Using a kind of device of embodiment, the method in two in conjunction with the embodiments, user can be by way of button operation
One key removes corresponding function module in each data cache module and generates data cached, and caching letter is quickly removed to realize
The purpose of breath avoids the situation that data cached removing function is respectively started in each submenu of digital oscilloscope, carries
The high execution efficiency of the removings function of digital oscilloscope, the operation readiness for also improving user are experienced.
Use above specific case is illustrated the present invention, is merely used to help understand the present invention, not limiting
The system present invention.For those skilled in the art, according to the thought of the present invention, can also make several simple
It deduces, deform or replaces.
