Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
First embodiment of the invention relates to a kind of jamming-proof terminal radio frequency test macro, comprise at least two p-wires, in every p-wire, comprise at least two test station, test-types corresponding at least two test station wherein, the position of the test station of same test type on adjacent two p-wires is different.
Present embodiment is the test macro of single-mode terminal, and the test station of the different test-types here refers to frequency calibration website and communication test website.That is to say, if frequency calibration website is at front communication test website rear on a p-wire, on adjacent another p-wire, communication test website is calibrated website rear at front frequency.Utilize rational p-wire website to distribute to increase the distance between the test station of same test type, by space attenuation, reduce upward signal impact on upward signal on downstream signal or downstream signal between different p-wires.
Second embodiment of the invention relates to a kind of jamming-proof terminal radio frequency system equally, and present embodiment is improved on the basis of the first execution mode, and in the present embodiment, the terminal of testing is multimode terminal, at least supports two communication patterns.
When carrying out website distribution, can only the communication test website of same communication pattern be arranged in to the diverse location on adjacent two p-wires, also the website of same communication pattern all can be staggered, can also be by each test station sorting by reversals on adjacent two p-wires, even where necessary, when as more in test station, can be after sorting and staggering, then carry out integral inverted to.The object of above-mentioned variety of way is utilizes rational p-wire website to distribute to increase the distance between the test station of same test type, by space attenuation, reduces upward signal impact on upward signal on downstream signal or downstream signal between different p-wires.
The p-wire of TD-SCDMA/GSM dual-mode terminal of take is example, Fig. 1 shows the distribution of test station on each p-wire in prior art, because the distance between communication test website is very near, therefore between each measurement circuit terminal, can produce greatly and disturb, especially for TD-SCDMA communication test website, what use due to its up-downgoing is identical frequency, so disturb very obvious.
Adopt present embodiment, on adjacent two p-wires, the sequence of each test station is as shown in Figure 2: p-wire 1:TD-SCDMA frequency calibrated meter → GSM frequency calibrated meter → gsm communication test instrumentation → TD-SCDMA communication test instrument ....P-wire 2:TD-SCDMA frequency calibrated meter → GSM frequency calibrated meter → TD-SCDMA communication test instrument → gsm communication test instrumentation ....Thereby the communication test website of TD-SCDMA on two p-wires is staggered, reduce the interference between two websites.
Also can be after sorting and staggering, then carry out integral inverted to, as shown in Figure 3.P-wire 1:TD-SCDMA frequency calibrated meter → GSM frequency calibrated meter → gsm communication test instrumentation → TD-SCDMA communication test instrument ....P-wire 2:GSM communication test instrument ← TD-SCDMA communication test instrument ← GSM frequency calibrated meter ← TD-SCDMA frequency calibrated meter ....Thereby make on adjacent p-wire each test station position of same communication pattern all different, can reduce to the full extent by two signals between website and disturb.
Third embodiment of the invention relates to a kind of jamming-proof terminal radio frequency test method, the uplink and downlink works frequency range of this terminal is identical, it can be specifically TD-SCDMA terminal, during test, in its working frequency range, get two discontinuous frequencies, use the first frequency to carry out the uplink communication test of terminal, use the second frequency to carry out the downlink communication test of terminal.For example the up test frequency of terminal is 10054MHz, and the descending test frequency of its correspondence no longer adopts 10054MHz, and adopts 10070MHz.Utilize frequency division mode separately to measure up-downgoing index, reduce upward signal interference to upward signal to downstream signal or downstream signal between each p-wire.
Four embodiment of the invention relates to a kind of jamming-proof terminal radio frequency test method, and in the method, at least two p-wires communicate test simultaneously, wherein on a p-wire, send frame synchronizing signal; All p-wires, according to this frame synchronizing signal, synchronously carry out uplink and downlink communication test.
When specific implementation, take the test macro shown in Fig. 1 as example, can be with a TD-SCDMA instrument output frame synchronous timing signal (5mS frame synchronization Trig signal), other TD-SCDMA instrument are carried out Timing Synchronization with this Trig signal, consistent to guarantee the 5mS subframe time reference of every TD-SCDMA instrument, uplink and downlink timeslot between the TD-SCDMA pattern of each test terminal will can be not overlapping so, just there will not be upward signal to have influence on descending index test yet.As shown in Figure 4, with the synchronous Trig signal of TD-SCDMA calibrated meter output 5mS of p-wire 1, and other p-wires TD-SCDMA instrument is inputted this Trig signal, take this Trig signal as time reference maintenance TD 5mS synchronizing sub-frame.By test station instrument, send frame synchronizing signal, guarantee the Timing Synchronization of the test station time of same communication pattern on each p-wire, can thoroughly solve the mutual interference between p-wire terminal and website instrument.
The respective embodiments described above of the present invention can combine, to reach better anti-tampering effect.In the first or second execution mode, communication test website can be got two discontinuous frequencies equally in TD-SCDMA working frequency range, uses the first frequency to carry out the uplink communication test of terminal, uses the second frequency to carry out the downlink communication test of terminal.Utilize frequency division mode separately to measure up-downgoing index, further reduce upward signal interference to upward signal to downstream signal or downstream signal between each p-wire.
Equally, in the first or second execution mode, the test station of a p-wire comprises a synchronization module therein, for sending frame synchronizing signal; On all p-wires, communication test website be take this frame synchronizing signal as benchmark, synchronously carries out uplink and downlink communication test.Specifically as shown in the 4th execution mode.
Equally, also the third and fourth execution mode can be combined, in the situation that sending frame synchronizing signal, use different frequencies to carry out the uplink and downlink communication test of terminal.
Equally, also can be by the one the 3 4th or the two the 3 4th execution mode combinations, to reach better anti-jamming effectiveness.
Because each execution mode of the present invention is when terminal room disturbs on each p-wire in reducing radio frequency testing, without retest or increase shield facility, thereby can not affect production efficiency and increase, produce line cost.
Although pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and described, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
