A described state setting module of measuring arranges and measures mode that institute in a memory module store use state of each measurement item and can have a variety of.Here, we specifically provide three kinds of feasible embodiments.But should point out, these three kinds of embodiments are only in order to illustrate, not in order to limit protection scope of the present invention.Those skilled in the art arrange the use state of measuring item with other any predictable related embodiment, all should be considered as within protection scope of the present invention.
Oscillograph embodiment one
A described measurement state setting module is used mode set command to set up according to the user and is effectively measured a storage queue.This effectively measures a storage queue, is used for using the mode set command storage to be in the measurement item of effective status (can use) according to the user.The item memory module is identical with measuring, and this is effectively measured the measurement item of storing in storage queue and comprises the perfect measurement item information of measuring item, the waveform characteristic that namely includes this measurement measured waveform information source and will measure.As seen, the measurement item of storing in this effective measurement storage queue should be for measuring the subset of the measurement item of storing in a memory module.Only have, store in measuring a memory module and the measurement item that is in effective status just is stored in this and effectively measures in item storage queue.
Like this, when oscillograph is measured analytical calculation, only need directly effectively to measure from this and call its effective measurements item of storing storage queue and get final product.And when the user need to carry out invalid or recovery operation to the correlative measurement quantifier, also only need the deletion or call from measure a memory module and be stored in the storage queue of effective measurement item and get final product from effective measurements storage queue of correlative measurement quantifier.Aforesaid operations does not all need the measurement item that a measurement memory module is stored is changed, and therefore need not the user and again arranges measuring item, has facilitated user's flexible operating.
Oscillograph embodiment two
A described measurement state setting module is used mode set command to set up according to the user and is measured a status list.This measures a status list, and each measures the use state parameter of item for use the described measurement memory module of mode set command storage according to the user; The use state that this use state parameter is measured item in order to identify each.This use state parameter identifies at least and comprises two kinds of use states: effectively with invalid.
Different from above-described embodiment one, in the present embodiment, a measurement status list is not directly stored the perfect measurement item information of measuring item, but only stores the use state parameter of measuring item, so that in sign measurement item memory module, each measures the use state of item.And, measuring the measurement item use state parameter of storing in the item status list and measuring the measurement item of storing in a memory module is one-to-one relationship, and the measurement item correspondence of namely storing in each measurement item memory module is measured use state parameter in a status list.
Like this, when oscillograph is measured analytical calculation, need to identify the use state parameter of correlative measurement quantifier in this measurement status list by measuring a state recognition module, and call the correlative measurement quantifier that is in effective status from measure a memory module, to carry out the analytical calculation of correlative measurement quantifier.And when the user need to carry out invalid or recovery operation to the correlative measurement quantifier, only need to modify to relevant use state parameter in a measurement status list got final product.Aforesaid operations does not all need the measurement item that a measurement memory module is stored is changed, and therefore need not the user and again arranges measuring item, has facilitated user's flexible operating.
Oscillograph embodiment three
Add the use state parameter in described each measurement item information of measuring of measuring that a state setting module uses that mode set command stores according to the user in measuring a memory module; This use state parameter is measured the use state of item in order to identify the place.Herein measurement item uses identical in state parameter and embodiment two, and sign comprises two kinds of use states at least: effectively and invalid.
The present embodiment and embodiment two are similar, just each use state parameter of measuring not centralized stores independently measure in a status list in one, but pass through to revise the measurement item information that each measures item, join in each measurement item information of measuring item.
In this embodiment, although need to modify to measuring each measurement item of storing in a memory module.But its operation of carrying out only limits to revise measure in item information measures a use state parameter that uses state in order to sign, and the measurement item of a measurement memory module not being stored carries out content modification or the deletion of essence.When oscillograph is measured analytical calculation, need to identify each use state parameter of measuring correspondence in item by measuring a state recognition module, call the correlative measurement quantifier that is in effective status according to the information that this use state parameter identifies from measure a memory module, to carry out the analytical calculation of correlative measurement quantifier.And when the user need to carry out invalid or recovery operation to the correlative measurement quantifier, only need to modify to relevant use state parameter got final product.
In addition, need consideration for storage space and actual use, the measurement item bank bit in order to storage measurement item that a described measurement memory module provides is limited.In the present embodiment, a described measurement memory module provides five to measure a bank bit altogether.
Have, the described measurement item of storing in a memory module of measuring is stored with the sequential storage structure again, storage morning that namely early arranges, the storage in evening of setting in evening.And when measuring measurement item bank bit that a memory module provides when not enough, its replacement operation is also with this storage order, the preferential deletion that early arranges, the deletion in evening that arrange evening.Certainly, should consider equally each measurement current use state in delete procedure, the measurement item that is in disarmed state is preferentially deleted.
In addition, in order to be user-friendly to, the present invention also is provided with a key control module in this measurement control module.This key control module, all measurement items that are used for a measurement memory module is stored carry out unified use status modifier operation, as unified be revised as effective status or disarmed state or all measure a use state all change (effective status change disarmed state into, disarmed state change effective status into).Can unify to revise by this key control module the current use state that each measures item, for user's operation is provided convenience.What should be pointed out that still that a key control module here revises is only to measure the use state that each that identify in a state setting module measured, does not carry out any modification to measuring the measurement item of storing in a memory module.
Fig. 2 is the oscillographic implementation method process flow diagram that the present invention has controlled measurement function.As shown in the figure, this oscillographic implementation method comprises:
According to the user, instruction is set the measurement item information of measuring item is set; At least include waveform information source and waveform characteristic in this measurement information;

If should measure and use state to be disarmed state, revise the use state parameter in the measurement item information of this measurements item, make this use state parameter be designated effective status.
In this embodiment, although need to modify to measuring each measurement item of storing in a memory module.But its operation of carrying out only limits to revise measure in item information measures a use state parameter that uses state in order to sign, and the measurement item of a measurement memory module not being stored carries out content modification or the deletion of essence.
In addition, the other key point of the present invention is by measuring a state recognition module, set measurement item use state to be identified, to operate accordingly.Equally, corresponding to aforementioned three different embodiment, it is also not identical that this measures a use state recognition process of state recognition module.Therefore, we use the state recognition process to be introduced with regard to it respectively here according to aforementioned three embodiment.
Recognition method one
For embodiment of the method one, this uses the state recognition process as follows:
Judge whether use state measurement item to be identified is stored in effective measurement storage queue;
If be stored in effective measurement storage queue, this measurement item is in effective status;
If be not stored in effective measurement storage queue, this measurement item is in disarmed state.
Recognition method two
For embodiment of the method two, this uses the state recognition process as follows:
Judge the corresponding state parameter that uses of use state measurement item to be identified institute in measuring a status list;
If this use state parameter is designated effective status, this measurement item is in effective status;
If this use state parameter is designated disarmed state, this measurement item is in disarmed state.
Recognition method three
For embodiment of the method three, this uses the state recognition process as follows:
Judge in the measurement item information of use state measurement item to be identified and use state parameter;

As shown in Figure 7, at first the waveform at the right menu setecting measurement of oscillograph item is the square wave of passage 1, and then by left menu, this measurement waveform characteristic that will measure being set is frequency measurement.What therefore, this measurement item will carry out is the frequency measurement of passage 1 square wave.After the setting of above-mentioned measurement item was completed, oscillograph inside was in measuring a control module, and the measurement item that this setting is completed is stored in to be measured in a memory module, and the use state of this measurements item is set by measuring a state setting module.
2, invalid measurement item
As shown in Figure 8, be provided with passage 1 peak-to-peak value (Vpp), frequency (Freq) in this embodiment, passage 2 peak-to-peak values (Vpp), frequency (Freq), and the time-delay (Dly) between passage 1 and passage 2 are measured item for totally five.And only need be to the peak-to-peak value of passage 1, when frequency is measured as the user, it does not need its excess-three measurement item.Therefore, based on the designed oscillograph of the present invention, the user need not to delete these three relevant settings of measuring item, gets final product and only need invalid these to measure item.As shown in Figure 8, the user makes the correlative measurement quantifier be disarmed state by the state that uses that a measurement state setting module arranges by to three illegal commands of measuring item of the time-delay between passage 2 peak-to-peak values, frequency, passage 1 and passage 2.Like this, oscillograph can not measured computing to these three invalid measurements in follow-up actual measurement, measures and shows result and only passage 1 peak-to-peak value, two of frequencies are effectively measured item.
3, recover to measure item
As shown in Figure 9, when the user need to measure peak-to-peak value, the frequency of passage 2, and when need not passage 1 is measured, the user only needs that two of peak-to-peak value, the frequencies of passage 1 are measured item illegal command is set, and two of peak-to-peak value, the frequencies of passage 2 are measured item, the recovery instruction is set, thereby makes the correlative measurement quantifier carry out corresponding modify by measuring a use state of state setting module setting.In this invalid and rejuvenation, do not change because the measurement item information of correlative measurement quantifier is stored in to measure in a memory module always, so do not need the user again the correlative measurement quantifier to be arranged.By aforesaid operations, oscillograph can not measured passage 1 in follow-up measurement again, and only can measure and show result the correlative measurement quantifier of passage 2.
Simultaneously, as seen in this embodiment, oscillograph also provides a key control function, can only carry out single stepping by this key control function and namely completes the invalid of above-mentioned five measurement items or recover instruction.
In sum, the invention provides a kind of oscillograph and its implementation with controlled measurement function, by wherein measuring the item state setting module and measuring a state recognition module, oscillograph can arrange the use state of measuring item has been set.The user only changes the use state of this measurement item, and does not modify to being stored in the measurement item of measuring in a memory module when operation correlative measurement quantifier.Like this, need not the setting operation that the user re-starts this measurement item, greatly facilitate user's use.Persons skilled in the art any not creative transformation of doing under this design philosophy all should be considered as within protection scope of the present invention.
