Description
Technical field
The present invention relates to spectrum analysis field, more particularly to a kind of trajectory processing being applied in spectrum analyzer are newly square
Method.
Background technology
In spectrum analyzer, more information are obtained from frequency spectrum data in order to facilitate user, typically can all be provided more
Bar track, and can provide simultaneously for every track such as refresh display, it is maximum keep, it is minimum keep and video it is average this four
Kind tupe.In these four patterns, in addition to refreshing and showing, its excess-three pattern is all referred to current spectral data
After being handled with historical data, final display data can be just obtained.Such as, it is necessary to ought in the case of maximum be kept
The frequency spectrum data of preceding acquisition and last frequency spectrum data carry out maximum holding operation between the two, and the result after processing is stored
Into display buffer, screen is sent to afterwards and is shown.After original initial data is obtained again next time, mistake above is repeated
Journey, so as to realize that the maximum of track keeps display function.Minimum keeps similar therewith with video averaging process.Said process
It is the normal operation flow after track tupe is set, now the problem is that when trajectory processing pattern changes
(for example remaining switched to minimum holding pattern or video average mode by maximum), above-mentioned repetitive process will be interrupted, journey
Sequence should be handled according to new trajectory processing pattern.But now due to the data in the display buffer of track still interrupt
Last frame data before.Obviously, if recycling the data in display buffer and the data that newly obtain under new model
Respective handling is carried out, obtained display data is incorrect.So switch (can also be referred to as at breakpoint) in emergence pattern
Afterwards, how handling historical data present in the display buffer of track must just solve the problems, such as one.
Processing method at present in spectrum analyzer is as follows：After the tupe of track changes, root in a program
According to the new model after switching, artificially the data of display buffer are initialized.Such as when tupe is cut from display is refreshed
After changing to maximum keep, the work for needing to do in a program includes two aspects：1) mark of data processing mode is carried out；2) because
Maximum holding pattern is now switched into, then is needed the setting value of current track display buffer to a very small numerical value
(for example being set to -500.0), become the initial data that initial history data obtain again and newly and carry out maximum holding computing,
So as to obtain the first frame data under maximum holding pattern；When being switched under minimum holding pattern, then need display buffer
Data initialization in area is to a very big value.In specific programming, current way is initialised to reference to electricity
It is flat residing numerically (for example with reference now to level to be 0dBm, be then initialised to 0.0；It is if 10dBm, then its is initial
Change to 10.0.) artificially initialize the data of display buffer and as the initial history data after pattern switching, Zhi Houzai
Into normal handling process so as to realizing the pattern switching of track.
Prior art has the following disadvantages：
1), it is necessary to artificially be initialized to the data in the display buffer of track after pattern switches, and this
Initialization needs the initialization according to corresponding to being carried out the identification number of track and current datum.The variable being related to and consideration
Factor is more, and realization is wasted time and energy first.
2) when spectrum analyzer provides multiple track datas, data processing is complex, is not easy to maintenance and expansion.
After pattern switches, although handling the display data for correctly obtaining the first frame by prior art,
Clearly display data now is exactly that pattern switches the initial data obtained afterwards.But for this number of acquisition
According to program needs to carry out two steps：First, the artificial initialization of display buffer is carried out first；Second, after initialization
The raw spectroscopy data that obtains again and newly of data carry out processing under new model.It is time-consuming, laborious for the angle of program.
The content of the invention
For the trajectory processing method in existing spectrum analyzer after hand-off process pattern, to display buffer
Operating process existing for data processing is complicated, it is necessary to artificial the problem of initialization to the data in display buffer, this
Invention provides a kind of trajectory processing new method being applied in spectrum analyzer.
