Examination, compared with existing ripe method of testing, low port number equipment（Within 16 passages）The suitable even more high of test accuracy rate, can
To illustrate that method of the present utility model and device have good industrial applicability especially, the utility model can be to existing
The 5G equipment more than 16 passages that technology is had no way out fast and accurately is tested, and solves this area a great problem.
When there is prior art test by testing multi-path-apparatus only and the utility model, or prior art
When test performance parameter has relatively large deviation with the utility model test performance parameter, test object is subjected to practical application, as a result
Display the utility model more tallies with the actual situation.Such as when testing 8 channel units, quantity 35, prior art test
There is no substandard products；But present invention test finds that 1 equipment has parameter error, by actual verification, this equipment is implicitly present in
Parameter error；If by its direct practical application, at least ten million yuan of loss can be caused；Equally 140 16 channel units are examined
During survey, prior art finds that 1 equipment error is larger, of the invention then 4 equipment errors of discovery are larger, by actual verification, 4
Equipment is implicitly present in parameter error, it is necessary to could be applied after correcting.On the one hand the technique effect of the present invention is embodied, can also be illustrated
Prior art is unable to do what one wishes to multi-path-apparatus.Especially in terms of testing efficiency, it is too many that the present invention is higher by prior art, takes not
Its twenty percent of foot.
Specific embodiment is applied in the utility model to be set forth principle of the present utility model and embodiment, with
The explanation of upper embodiment is only intended to help and understands method and its core concept of the present utility model；Meanwhile for this area
Those skilled in the art, according to thought of the present utility model, there will be changes in specific embodiments and applications, especially
Its change of installation site, mounting plates structure profile to the increase and decrease in multichannel integrated RF interface number and on the supporting plate
Change, in the range of this patent covers.
