Specific embodiment
Embodiment:
Fig. 1 to Fig. 5 is please referred to, the present embodiment shows that a kind of wireless communications products noise budget control removes wrong measurement system,
Be scanned including PNS microscope carrier Noise scan instrument: PNS is corrected with coplanar microstrip line, and measurement is to give off from microstrip line
Energy, this energy can be used to replace causing Conduction Interference, do caused by the components such as circuit coupling and antenna coupling or module
Disturb energy；Measurement includes the following steps:
1) corrector measurement probe position correction is compared；
2) the placement position positioning correcting of determinand is carried out；
3) structure is improved by the noisiness degree of discrimination and carries out noise identification；
4) system measurements and uncertainty evaluation are carried out: it is different for varying environment condition and instrument, to master below
It measures uncertainty source and carries out analysis assessment:
The measurement parameters measured can not 4-1) be grasped completely；
Method for measurement 4-2) measured is imperfect；
The environmental condition of measurement can not 4-3) be grasped completely；
4-4) performance of measuring instrument, jig or standard component is not sufficiently stable；
4-5) the retrospect value inaccuracy of measuring instrument or standard component or reference material；
4-6) personnel are inaccurate to the readings identification of analog instrument；
5) error of wide-angle lens institute's capturing picture and actual size is substituted into: since wide-angle lens mirror surface is non-planar, institute
With unit pixel that under the different altitudes, wide-angle lens is shone can difference, cause probe to be clapped according to camera lens
When the pixel arrived moves, the case where having positional shift or difference generation；With lens correction plate, make on different height
The movement of the corresponding picture pixel correction of one height, to solve picture curved edge caused by flake phenomenon, and in camera lens of arranging in pairs or groups
The position correction mode of the heart and probe allows probe can be more by two correcting modes according to the picture captured
User is accurately fallen in want within the scope of measuring；
6) scanning obtains data, and carries out data preparation and archive.
Further, PNS microscope carrier Noise scan instrument, which is placed in, efficiently inhales in waves shielded box 8, efficiently inhales waves shielded box, packet
The hollow cube 8 being made of the connection combination of upper wall 81, lower wall 82, left wall 83, right wall 84, antetheca and rear wall 85 is included, antetheca is set
It is set to chamber door, and is uniformly laid on upper inside walls, downside inner wall, inner left wall, right side inner wall, front inner wall and rear side inner wall
There is wave-absorber material 86, and upper inside walls, downside inner wall, inner left wall, right side inner wall are respectively arranged with poliarizing antenna 87.
Absorbing material 86 selects EMERSON & CUMING wave-absorber.
Poliarizing antenna 86 is dual polarized antenna.
Upper wall 81, lower wall 82, left wall 83, right wall 84, antetheca and 85 junction of rear wall are provided with sealing material.
Further, laser alignment risk management setting is carried out: in order to avoid every time in the height of detecting Stage or DUT
, often can be not appropriate enough at a distance from platform because of laser when spending, cause laser ranging to be easy error, and then lead to measurement executes effect
Rate reduces.Therefore board needs laser alignment risk management；Tester need to first measure determinand when measuring using PNS
Highly, if the excessive height of determinand or it is too low when, laser can not be operating normally, and tester should can not be by this case
Lower measurement；If therefore risk management may be designed to that the distance measurement function of correlation can not be chosen apart from inappropriate；When laser and put down
The distance of platform, which reaches, suitably can just choose distance measurement function；A line is pulled out from the signal source of laser to trigger to DAQ control card,
In laser low signal can not be sent out to software, so that software is generated warning or user can not measure under operative scenario.
PNS microscope carrier Noise scan instrument include be set to X-axis slide rail 1, the fixation carrier 2 that is set in X-axis slide rail 1, setting
Measurement probe 3 above X-axis slide rail 1 and corresponding with fixed carrier 2, when scanning, elder generation's scanning of a surface is each in a manner of laser
Point height is tested, measurement probe maintains the spacing of 1 mm to measure according to the height setting of laser ranging with determinand；Setting height
Difference set is on each measuring point, and when being moved to this every time with construction, probe can be moved up and down automatically to the point from probe
The distance of the vertical height of 1mm, can the entire IC plate of single pass.
Measurement probe 3 be connected on the Z axis 4 being correspondingly arranged above X-axis slide rail 1, and be connected to preamplifier 31, and
Fixed 2 front end of carrier is provided with the trigger sensor 21 being used cooperatively with measurement probe 3；3 slamming down of measurement probe is to be measured
When object, triggered by trigger sensor 21, equipment downtime.
Trigger sensor 21 is made of light sensor, and measurement probe is slidably to be set on Z axis 4, and top connects
It is connected to tension spring 5.
PNS microscope carrier Noise scan instrument equipped with meet each international money communication apparatus such as Apple, HP, DELL, Lenovo,
The system compensation software of the specifications such as NOKIA, MOTO, SONY is by correction program systematization.
Compare corrector measurement probe position correction specifically: in setting correction image A, correction on test reference face
Image A is the administrative division map scanned needed for measurement probe, after changing new measurement probe, obtains the region that measurement probe really scans
Scheme B, by contrast district figure B and correction image A, after pass sequentially through Y-axis adjust and X-axis adjust, finally make administrative division map B and correction
Image A is overlapped, and rear measurement probe position is the accurate location after correction；
Y-axis is adjusted are as follows: and whether the measuring point portable cord L1 for setting laser coincides with the L11 of the administrative division map really scanned, this
When multiaxis regulating system adjustment laser or measurement probe, be overlapped L1 and L11；
X-axis is adjusted are as follows: and it is parallel with X-axis by adjusting laser and the straight line L2 that measurement probe is linked to be, utilize vernier caliper
Measurement probe top B2 and the spacing with laser point A1 are measured, and calculates the needed X-direction movement of this spacing, realizes X-axis tune
Section.
Step 2 is carried out by the placement position positioning correcting structure of comprehensive adjustment formula determinand, comprehensive adjustment formula determinand
