Technical field
The present invention relates to technical field of measurement and test, and in particular to a kind of applicable aerospace level Multi-channel microwave component environment experiment
Switching network.
Background technology
In avionics equipment, the Multi-channel microwave component such as T/R components is equally existed.In Practical Project practice,
Each microwave multifunctional module is required for carrying out environmental test test one by one, and its environmental test condition is still very harsh
, if the spaceborne T/R component environments test temperature of certain type is -45~85 DEG C, this significantly larger than current most of tester equipment
Operating temperature range.
As shown in figure 1, aerospace level Multi-channel microwave component environment test system is typically by general test instrument, state
A few part compositions such as control device, switching network, main control computer, test fixture and environmental test chamber.General test instrument, shape
State control device and main control computer are typically placed in chamber side, will not enter in chamber.Test fixture directly with quilt
Survey component to be attached, therefore, be necessarily positioned in environmental test chamber.And switching network is the important composition portion of test system
Divide, and the equipment few in number for needing to customize, its one end are attached with tester, the other end is connected with MUT module under test
Connect, be mainly used to realize the automatic foundation and switching of TCH test channel, also complete signal condition (such as transmission signal coupling of MUT module under test
Conjunction/decay, pumping signal work(grade), while with its importance and complexity, its performance indications to whole system, reliability,
The influence of cost, maintainability also own profound.If MUT module under test passage is more, often and environmental test chamber is placed it in
In, so pass through chamber lateral through aperture or the microwave cable negligible amounts of connector.Go out spaceborne T/R groups as certain type 2 enters 48
Switching network needed for part test is just located in environmental test chamber, and so there is no need to throw away 50 microwaves by chamber
Cable, along with power supply and state control cable, actually environmental test chamber does not have space to allow the so many cable of quantity
Pass through.
As shown in Fig. 2 as a complete test equipment, switching network is mainly by computer module, switch control mould
The part such as block, microwave switch and block combiner, programmable interface module and AC/DC power modules forms.
Microwave switch and module typically have three generic ports, are power port, control port and microwave port respectively.It is most of
In the case of, power supply is dc source, therefore, inside switching network needs to be equipped with AC/DC power modules.Control port needs defeated
Enter the logic levels such as TTL, realize the switching of working condition, pins are controlled as the throw switch of hilted broadsword six shares 7, in different control letters
The action of switch is completed in the presence of number.Microwave port is attached with other microwave switch/modules and tester, they it
Between connection just constitute TCH test channel.
The workflow of switching network is as follows：(it is usually embedded computer by programmable interface module, computer module
Module) order from external system main control computer is received, and external command is translated and explained, command information is sent out
Internal pci bus is sent to, the generation of switch control module correspondence position switch controlling signal is realized with this, so as to reach control
Building for TCH test channel can be achieved in the combination of the purpose of microwave switch and module, multiple microwave switches and module position.Power supply
Then realize the power supply of computer module, switch control module and microwave switch and block combiner in part.
As shown in figure 3, said so that 2 enter 48 topological structures for going out the switching network needed for spaceborne T/R module testings as an example
It is bright.In addition to power supply, switch control and programmable interface part, inside shares 16 microwave switches, passes through the switching of switch, Ke Yishi
Existing TXOUT/RXIN1~48 to 288 passages such as frequency spectrograph, signal source, arrow net 1, oscillograph 1, power meter and noise source,
RXOUT/TXIN1~2 to 10 passages such as frequency spectrograph, signal source, arrow net 2, oscillograph 2 and acoustic meter amount to 298 passages
Build.There are 48 TXOUT/RXIN ports and 2 RXOUT/TXIN ports on switching network panel, it is corresponding with MUT module under test respectively
Port is attached；Panel also has frequency spectrograph mentioned above, signal source, arrow net 1, oscillograph 1, power meter, noise source, arrow net
2nd, 9 ports such as oscillograph 2 and acoustic meter, are also attached with corresponding tester respectively.
