Abstract
The invention discloses a kind of waveguide-to-coaxial adapter test fixture and test method, belong to communication test field.After waveguide-to-coaxial adapter test fixture using the present invention, simplify test system, only need to net attached coaxial calibrating device using arrow to two ports of arrow net, opened a way according to arrow network school quasi- guide, short circuit, load and thru calibration, eliminate waveguide calibrating device, swear that net port need not carry out coaxially arriving the conversion of waveguide port at the same time, convenient test, improves testing efficiency.
Description
Technical field
The invention belongs to communication test field, and in particular to a kind of waveguide-to-coaxial adapter test fixture and test method.
Background technology
Waveguide-to-coaxial adapter can realize coaxial interface to the signal transmission between Waveguide interface, and Waveguide coaxial turns
It is small to connect device, signal transmission quality is high, is a kind of widely used microwave component, especially in the various surveys such as radar and antenna
In test system.Existing testing scheme needs a port for swearing net being converted to waveguide test port, simultaneously because Waveguide coaxial
Adapter can not be connected directly with shaft end with existing coaxial connector, it is necessary to could be tested using associated clamps, and the whole series are surveyed
Test system is complicated, calibration trouble, and inefficiency, particularly with the waveguide-to-coaxial adapter simultaneous with multiplexing.
The content of the invention
For above-mentioned technical problem existing in the prior art, the present invention proposes a kind of waveguide-to-coaxial adapter test clip
Tool and test method, design is reasonable, overcomes the deficiencies in the prior art, has good effect.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of waveguide-to-coaxial adapter test fixture, including straight-through waveguide plate, coaxial adapter assembly, mounting screw, installation
Plate and mandril, wherein, coaxial adapter assembly is installed on installing plate by mounting screw, and mandril passes through peace as support member
Cartridge screw is installed on installing plate, leads directly to waveguide plate, is configurable for being fixed on two waveguide-to-coaxial adapters during test
Together.
Preferably, flexible inner wire is installed in coaxial adapter assembly, is followed by for ensureing that waveguide-to-coaxial adapter loads
Touch good.
Preferably, offered on installing plate with the relief hole stepped down with positioning action.
In addition, the present invention is it is also mentioned that a kind of test method of waveguide-to-coaxial adapter, this method use as described above one
Kind waveguide-to-coaxial adapter test fixture, specifically comprises the following steps：
Step 1：Two waveguide-to-coaxial adapters are fixed together by straight-through waveguide plate；
Step 2：Two waveguide-to-coaxial adapters being fixed together by leading directly to waveguide plate are loaded into installing plate, tighten peace
Cartridge screw；
Step 3：Coaxial signal is respectively connected at the both ends of coaxial adapter assembly, you can is tested.
Advantageous effects caused by the present invention：
After waveguide-to-coaxial adapter test fixture using the present invention, test system is simplified, it is only necessary to the two of arrow net
Attached coaxial calibrating device is netted in a port using arrow, opened a way according to the quasi- guide of arrow network school, short circuit, load and thru calibration, save
Waveguide calibrating device is fallen, while has sweared that net port need not carry out coaxially arriving the conversion of waveguide port, convenient test, improves test
Efficiency.
