Description
Technical field
The present invention relates to automatization testing techniques, in particular to wireless communications products noise testing technology, specifically, it is opened up
Show that a kind of wireless communications products noise budget control removes wrong measurement system.
Background technique
Wireless communications products have cloud calculating (Cloud with the demand of various applications and service
Computing), however each single item application or service must be set up is having the enough online rates (Throughput) could reality
It is existing.The speed of online rate is depending on by network foundation, packet size coding mode and error rate.Crossing higher position when error rate must
Must reduction of speed, the error rate of digital wireless communication and Eb/N0 (Eb is Energy per Bit, and N0 is equivalent Gaussian noise,
The two all appears in the Baseband of wireless communications products).
In addition to considering for its online rate needed for can not providing application and servicing caused by each wireless communication interference；
Similarly, used each perceptron (sensor) and touch control display also must be in wireless communications products on wireless communications products
It can normally be acted when transmitting, this includes power supply ripple caused when 2G/3G emits, power supply supply RF Power
(wireless communications products generally use miniature antenna to surface current when Amplifier when instantaneous peak current, antenna transmitting
Current distribution when Electrical Small Antenna, transmitting or reception is not limited to ESA but includes circuit board
And extremely thin coaxial wire etc..
Since in development in recent years, quickly, various communications protocol continues to introduce new wireless communication technical field, and wireless
The quality of communication is based on enough miscellaneous ratios (S/N) of news, and any communications protocol must all ensure that signal strength is higher than noise intensity
It can correctly be linked up to message, herein under the premise of one, emphasis that microscope carrier noise potential must be of interest for each wireless product manufacturer.With
The progress of science and technology and the arriving in cloud epoch, the circulation of data is increasing, and market is necessarily required to support multinomial mechanics of communication
And the product of higher speed network.
Therefore, it is necessary to which providing a kind of wireless communications products noise budget control removes wrong measurement system to solve above-mentioned ask
Topic.
Summary of the invention
The object of the present invention is to provide a kind of wireless communications products noise budget control to remove wrong measurement system.
Technical solution is as follows:
A kind of wireless communications products noise budget control removes wrong measurement system, including PNS microscope carrier Noise scan instrument is scanned:
PNS is corrected with coplanar microstrip line, and measurement is the energy given off from microstrip line, this energy can be used to replace causing to conduct
It interferes, interfering energy caused by the components such as circuit coupling and antenna coupling or module；Measurement includes the following steps:
1) corrector measurement probe position correction is compared；
2) the placement position positioning correcting of determinand is carried out；
