Embodiment
For making the object of the invention, technical scheme and advantage clearer, the embodiment of the invention is done further explain below in conjunction with accompanying drawing.At this, illustrative examples of the present invention and explanation thereof are used to explain the present invention, but not as to qualification of the present invention.
The embodiment of the invention provides a kind of state synchronization method, is applied to spectrum analyzer and the computing machine that is connected with spectrum analyzer, and Fig. 1 is a process flow diagram of the state synchronization method of the embodiment of the invention.
As shown in Figure 1, said method comprises:
When step 101 was implemented, computing machine can read the status information of spectrum analyzer through the SCPI order in the communication process of frequency spectrum data.Communication process can be the transmission of computing machine of completion to spectrum analyzer, is carrying out the read process of spectrum analyzer to computing machine.
For example, can send following command sequence to spectrum analyzer:
：GetSpectrumData?；：GetStateChange?
Through the mentioned order sequence, can get access to frequency spectrum data and status information.More than be merely obtaining the schematic illustration of status information, but be not limited thereto, can confirm concrete embodiment according to actual conditions.
When step 101 was implemented, whether the state that status information is used to identify spectrum analyzer changed, and can be bit, for example, adopts 0 expression state not change, and adopts 1 expression state to change; Perhaps can adopt ASCII character.But be not limited thereto, can confirm concrete embodiment according to actual conditions.
When step 102 was implemented, computing machine can judge at first whether the state of spectrum analyzer changes according to status information, if do not change, did not then read the status data of spectrum analyzer.
If change, can judge further that then the current frequency spectrum data that whether reading perhaps sends control data, if the current frequency spectrum data that do not read perhaps sends control data, then directly reads the status data of spectrum analyzer; If currently reading frequency spectrum data or sending control data, then after the current communication process that reads frequency spectrum data or send control data finishes, read the status data of spectrum analyzer again.
When step 102 was implemented, computing machine can also judge at first that the current frequency spectrum data that whether reading perhaps sends control data, if the current frequency spectrum data that do not read perhaps sends control data, judges further then whether the state of spectrum analyzer changes.If state does not change, then do not read the status data of spectrum analyzer; If change, then directly read the status data of spectrum analyzer.
If currently reading frequency spectrum data or sending control data, then after the current communication process that reads frequency spectrum data or send control data finishes, judge further more whether the state of spectrum analyzer changes.
