Description
Technical field
The present invention relates to the testing field of T/R components, and in particular to a kind of dress of raising T/R component test system securities
Put and method.
Background technology
It is defeated in addition with radio frequency mainly comprising three transmission channel, receiving channel and drive control parts in T/R components
Enter the component interface such as output, low-frequency connector part.Transmission channel mainly completes the amplification of rf excitation signal, and exports to feedback
Gauze network；The echo-signal that receiving channel receives antenna is amplified, and ensures relatively low noise coefficient；The transmit-receive switch of component is cut
Change and phase, the control of decay are completed by drive control part.
T/R components have the characteristics that more passage, high or low power and deposited and multiplexed port, and index species is more, it is necessary to more
Kind tester could be completed to test.So-called high or low power is simultaneously deposited, i.e., transmission channel output power, receiving channel power are small；
For multiplexed port, that is, launch output port and namely receive input port, launch input port i.e. Rreceive output end
(it is different also to have some T/R components transmitting input port and receiving port to mouth, but it is also reception certainly to launch output port
Input port), it is the working system of a timesharing certainly.Therefore, the test of T/R components is realized more difficult, also very multiple
It is miscellaneous, test is completed using test system mostly, this just needs to nurse one's health receiving and transmitting signal, then utilizes the switching of switching network
Building for TCH test channel is realized, and then completes the test of transceiver channel performance indications.
Because T/R component transmission signal power is generally large, it can not input in instrument and directly be tested, transmission signal must
It must be decayed or could be tested after coupling conditioning using tester.But for T/R module testings, due to
The characteristic of multiplexing is received and dispatched, while nursing one's health transmission signal, the power attenuation that should not result in reception input signal is excessive
(10dB is typically not to be exceeded), the inaccurate feelings that can not even test of noise coefficient test result of receiving channel otherwise can occur
Condition occurs.It is general using built-in attenuator or directional couple in switching network when being tens watts of magnitudes for transmission power
Device, switch switching is recycled to realize the Opsonizing method for receiving and dispatching separation.
As described in Figure 1, by taking the T/R module testings of certain type as an example, it has 2 transmitting input/Rreceive output ports, 22 transmittings
Output/reception input port.Mainly there are 11 microwave mechanical switch (5 throw switches of hilted broadsword six, 3 hilted broadswords inside switching network
Four throw switches, 3 single-pole double-throw switch (SPDT)s) and 3 attenuator compositions, the AC/DC of certainly also promising switch offer power supply and control
The part such as power module, switch control module (part containing programmable interface) (Fig. 1 is not drawn).And there are 31 external connection ends on panel
Mouthful, tested T/R components transmitting input/Rreceive output 1~2 port of the port of wherein TXIN/RXOUT1~2 connection, TXOUT/RXIN1
Connection tested T/R components transmitting output/reception in~22 ports inputs 1~22 port, and other 7 ports are corresponding according to mark connection
Tester.
Its internal annexation is：The port of TXIN/RXOUT1 on the corresponding connection panel of SW1-1~2~2 is switched, and is opened
Close SW1-C ports connecting valve SW7-C ports, switch SW7-3~6 ports difference connecting valve SW9-1 ports, SW10-1 ends
Acoustic meter port and vector network analyzer port 1 on mouth, panel, the connecting valve SW9-2 ports of attenuator 1, switch SW9-C ends
Spectrum analyzer port on mouthful connection panel, the port of TXOUT/RXIN1 on panel~22 correspond to connecting valve SW2-1~6, SW3-
1~6, SW4-1~6, the port of SW5-1~4, and switch SW2-C, SW3-C, SW4-C, SW5-C port and correspond to connecting valve SW6-1
~4 ports, switch SW6-C ports are attached with switch SW8-C ports, and switch SW8-1 ports are entered with switch SW11-1 ports
Row connection, SW8-2 ports are attached with attenuator 3, and SW8-3 ports are attached with attenuator 1, switch SW8-4 ports and
Switch SW10-2 ports are attached, and switch SW8-5 ports are attached with panel noise source port, switch SW8-6 ports and
Attenuator 2 is attached, and switch SW10-C ports are attached with panel signal generator port, attenuator 3 and panel peak value
Power meter port is attached, and switch SW11-2 ports are attached with attenuator 2, switch SW11-C ports and panel vector net
Network analyzer port 2 is attached.
During transmitting test, it is signal generator and vector network analyzer port 1 that input signal, which produces equipment, and signal occurs
The output signal of device is separately input into the end of TXIN/RXOUT1~2 through switching SW10-C, SW10-1, SW7-4, SW7-C, SW1-C
Mouthful, and the output signal of vector network analyzer port 1 is separately input into TXIN/ through switching SW7-6, SW7-C, SW1-C
The port of RXOUT1~2, and the high-power transmission signal exported through TXOUT/RXIN1~22 ports, switch SW2, SW3, SW4,
SW5, SW6 are extracted (synchronization only has a TXOUT/RXIN port to have transmitting output signal) all the way.Access switch SW8
Afterwards, enter vector network analyzer port 2 through SW8-6, attenuator 2, SW11-2, SW11-C, with this complete standing-wave ratio, phase shift,
The test of the transmission channel scattering parameter such as amplitude coincidence, phase equalization；Enter peak power meter through SW8-2, attenuator 3,
The test of the parameters such as transmission power, top drop, pulsewidth is completed with this；Divide through SW8-3, attenuator 1, SW9-2, SW9-C into frequency spectrum
Analyzer, the test of the transmission channel frequency spectrum parameter such as spuious, harmonic wave is completed with this.
When receiving test, it is signal generator, vector network analyzer port 2 and noise source that input signal, which produces equipment,
The output signal of signal generator is separately input into through switching SW10-C, SW10-2, SW8-4, SW8-C, SW6, SW2~SW5
The port of TXOUT/RXIN1~22, and the output signal of vector network analyzer port 2 through switch SW11-C, SW11-1, SW8-1,
SW8-C, SW6, SW2~SW5 are separately input into the port of TXOUT/RXIN1~22, the output noise of noise source through switch SW8-5,
SW8-C, SW6, SW2~SW5 are separately input into the port of TXOUT/RXIN1~22, and Rreceive output signal through TXIN/RXOUT1~
2 ports, switch SW1 are extracted (synchronization only has a TXIN/RXOUT1 port to have Rreceive output signal) all the way.Into opening
After closing SW7, enter vector network analyzer port 1 through SW7-6, completing phase shift, amplitude coincidence, phase equalization etc. with this connects
Receive the test of passage scattering parameter；Enter spectrum analyzer through SW7-3, SW9-1, SW9-C, completing spuious, harmonic wave etc. with this connects
Receive the test of channel frequency spectrum parameter；Enter acoustic meter through SW7-5, the test of the receiving channel parameter such as noise coefficient is completed with this.
Transmitting output signal is all decayed using attenuator, and is received input signal and output signal and all do not passed through
Attenuator, transmitting-receiving test separation is advantageously implemented the test of noise coefficient, while requires that the microwave machinery inside switching network is opened
Transmission power can be born by closing SW2~SW6, SW8 and whole attenuators.
Safety risks be present when being transmitting test in subject matter existing for existing Opsonizing method：
1) if SW8 has failure, SW8 is in 1 position, while SW11 is in 1 position, then high-power transmission signal is just entered
Enter vector network analyzer port 2, so as to burn.
If 2) there is failure in SW8, SW8 in 4 position, while SW10 also 2 position, then high-power transmission signal is just
Entering signal generator, so as to burn.
3) if there is failure, positions of the SW8 5 in SW8, then high-power transmission signal is put into noise source, so as to
Burn.
