The Wave data that obtains described here is from the original waveform data that waveform signal to be measured obtains after over-sampling, obtains the waveform correlation data in described self-defined measurement range.
5, described measurement result is shown.
The above-mentioned key that can customize the oscillographic implementation method of measurement range is, be provided with the vertical cursor line that can move along transverse axis that two of the first cursor lines, the second cursor line can be arranged by the user in this oscillograph, adjust the position of these two cursor lines by step 1, the measurement range that can customize setting is provided for the user, thereby provides oscillographic measurement mode more flexibly for the user.Fig. 2 is Wave data scope schematic diagram.We can clearerly see that Lookup protocol in self-defined measurement range provided by the present invention and prior art measures and specify the difference of the measurement pattern that measurement is set by this Fig. 2.So-called Lookup protocol measurement is that the Wave data for whole collections carries out analytical calculation, and the scope of its processing is relevant with the Wave data scope that gathers.So-called appointment arranges and measures is to carry out analytical calculation for the Wave data in oscillograph screen scope, and the scope of its processing is relevant with shown Wave data scope in the oscillograph screen.These two kinds of measurement ranges are established a capital the flexible setting that is not easy to the user really.And self-defined measurement range provided by the present invention is in oscillograph screen scope, by the user to the setting of two cursor line positions and definite.Therefore, determining of its measurement range is more flexible, and the user can measure easily according to self needs the parameter of partial waveform.
The order that should be pointed out that described step 1 and step 2 might not also can first be set the project that will measure according to the sequencing of above-mentioned flow process, then first, second cursor line position that limits self-defined measurement range is arranged.Above-mentioned flow sequence also should be within protection scope of the present invention.
Be described further below by the oscillographic implementation method that can customize measurement range of a specific embodiment to the invention described above.
As shown in Figure 3, be provided with two vertical cursor lines in this oscillograph, the first cursor line A and the second cursor line B.The user selects to arrange the first cursor line A, the second cursor line B or while operational light graticule AB by actions menu.The initial position of this cursor line A, B is generally by the random appointment of manufacturer.For example, in the present embodiment be start address take about screen center 3 lattice as cursor line A, B.The user changes the current cursor line position of choosing by rotation knob key.
Be noted that in the present embodiment, given cursor line adjustment mode operates by the knob key.But in addition, also can realize by other any operation that can change the measurement range parameter, for example, select the rectangular area on touch-screen, use mouse to select the rectangular area, use remote command configuration parameter etc.
Here, use in the remote command configuration parameter, remote command is the method for the general Long-distance Control instrument of all supporting of a kind of surveying instrument.This collocation method is followed SCPI (Standard Commands for Programmable Instruments, programmable instrument standard command set) standard.
As shown in Figure 4, by the measure the item in the button choice menus.In this example, what specifically select is " positive pulsewidth " option.After setting completed, oscillograph namely begins to measure with regard to this test event according to the self-defined measurement range that sets.
The concrete process of measuring, at first the self-defined measurement range that has arranged before the basis is obtained the Wave data in this self-defined measurement range from the Wave data that gathers, then according to setting measure the item " positive pulsewidth ", Wave data in the self-defined measurement range of obtaining is carried out analytical calculation, obtain corresponding measurement result.

As seen above-mentioned, in the oscillographic implementation method of self-defined measurement range, employing be that two vertical cursor lines limit user-defined measurement range.In addition, we can also arrange the cursor line of two levels again, and the cursor line of these two levels is respectively the 3rd cursor line and the 4th cursor line.When this first cursor line and the second cursor line position are set, the cursor line of these two levels also is set respectively, the position of the 3rd cursor line and the 4th cursor line.The rectangular area that is limited by above-mentioned first, second, third, fourth cursor line is described self-defined measurement range.Like this, technical scheme provided by the present invention not only provides the circumscription on horizontal direction, and the circumscription on vertical direction also is provided simultaneously, thereby makes the setting of this self-defined measurement range more comprehensive.
Due in some cases, the user the start address of self-defined measurement range early than the start address of collected by oscillograph Wave data, can cause like this error of oscillograph when analytical calculation.Therefore, for fear of this problem, the present invention also is provided with the comparison step that waveform acquisition start address and user is defined start address in described step 3 is obtained the step of Wave data, specific as follows:
Relatively waveform acquisition start address and user define the time sequencing of start address; If the waveform acquisition start address defines start address early than the user, define start address as the initial Wave data that obtains take the user; If the user defines start address early than the waveform acquisition start address, take the waveform acquisition start address as the initial Wave data that obtains.
Can guarantee that by above-mentioned steps the Wave data that obtains through step 3 is real effectively Wave data.

By above-mentioned, original waveform data is carried out the track pre-service, the step that makes described step 4 pair Wave data carry out analytical calculation only needs that this waveform envelope is carried out analytical calculation and gets final product, and effectively reduces the operand when Wave data is carried out analytical calculation.
Should be pointed out that the designer can also do further restriction to the pretreated data area of this track.Referring to Fig. 2, the pretreated data area of this track can be total data scope, display data on the screen scope and self-defined measurement data scope.By the pretreated data area of track is limited, can further reduce the pretreated operand of track.
When using the track pre-service, also need to define track initial coordinate Start
