Examination equipment, with the fast development of present mobile communication technology, especially forth generation (4G) communication base station system construction is as fire
Such as the carrying out of the bitter edible plant, the demand of cavity body filter is surged.This forms immense pressure to the production of unit wave filter, due to cavity
Wave filter electric performance test index is more, station is more, time-consuming, and the test job of wave filter also becomes increasingly heavy.
Wave filter carried out power test in the past, and intermodulation testing, S parameter test adopt independent test mode, tri- roads of Ji Fen
Operation, needs three sets of test systems to be respectively completed.Particularly power and intermodulation testing, needs independent signal source (follow-up frequency range customization
Signal source), power amplifier, audiofrequency spectrometer.And portioned product, need to test power and the intermodulation of multiple frequency ranges, it is necessary to which distribution is more
Station, more signal sources, power amplifier and audiofrequency spectrometer.So not only need many people operation, and more equipment, bigger need to be configured
Test site could meet Production requirement.While single machine test, it is impossible to unified to collect data, subsequently also need manually data are united
One is aggregated in form.
The content of the invention
For problem above, the present invention provides a kind of wave filter integrated test system, changes conventional filters to test side
Formula, greatly improves wave filter production efficiency, reduces personnel and puts into place, reduces enterprise's production capacity, improve enterprise
Production capacity, makes enterprise obtain more profits.
Technical scheme：In order to solve problem above the invention provides a kind of wave filter integrated test system, its feature exists
In, including power test part, intermodulation testing part, S parameter part of detecting, three part of detecting include terminal PC, switch,
Server, signal source/power amplifying device, matrix device, arrow net, audiofrequency spectrometer；
Power test part：When terminal PC sends operation instruction signal, server is sent to by switch, server with
Required test program is recalled, and operation signal is sent to signal source/power amplifying device and terminal PC, terminal PC by switch
The data signal for being involved in audiofrequency spectrometer test request sends audiofrequency spectrometer to by netting twine or GBIP cards；Signal source/power amplifying device
Power signal is sent by instruction, power signal sends measured piece to by matrix device, and power signal leads to Jing after measured piece filtration
Cross after matrix device is processed and send audiofrequency spectrometer to, Jing after audiofrequency spectrometer process pass through result data Jing terminal PC on switch
Server is passed, server judged result numerical value is whether in default numerical range, and the display processing result in terminal PC.
Intermodulation testing part flow process is consistent with power test flow process.
S parameter part of detecting：When terminal PC sends operation instruction signal, server, server are sent to by switch
Required test program is recalled, and operation signal is sent to into terminal PC by switch, terminal PC passes through netting twine or GPIB cards again
The data signal of test request is issued into arrow net, and arrow net sends power signal and measured piece distributed to by matrix device, and arrow net is same
Shi Jinhang power signals are received and are processed, and by result data Jing terminal PC by switch upload server, server
Whether judged result numerical value is in default numerical range, and the display processing result in terminal PC.
Described matrix device is matrix switch.Matrix switch is a kind of priority structure, and it has gathered cavity body filter institute
Various test interfaces are needed, various test distinct interfaces are realized, it is only necessary to which once mounting connection can be completed, and press interfacing order point
It is fitted on product, completes the various tests (power, intermodulation, the test of S parameter ATE) of product.
Three stations are incorporated into a station by the wave filter integrated test system of the present invention, and former wave filter production is surveyed
Examination needs three people of test man, three stations to take about 12 square metres of production site, first carry out power test, shift after the completion of test
To intermodulation testing, be then transferred to ATE test, the testing time under whole Qualifications about at 40 minutes, if running into bad products,
Can only know that certain single test link is bad, and not can know that whether other test links are qualified.After employing the technology of the present invention,
Same wave filter production test only needs one people of test man, a station to take about 4 square metres of production site, and the testing time about exists
20 minutes, and once test can know that the behavior pattern of link is tested in former three road, running into unfavorable condition disposably can keep in repair, efficiency
Greatly improve, enterprise's production capacity is obviously improved.
Description of the drawings
Fig. 1 is the theory diagram of this wave filter integrated test system.
Wherein, solid line represents power signal, and dotted line represents data signal.
Specific embodiment
Below in conjunction with the accompanying drawings, the invention will be further described.
