Fig. 2 is a circuit block diagram of the present utility model.
Fig. 3 is the circuit diagram of frequency division multiplexing of the present utility model and multi-channel gating device.
Embodiment
As shown in Figure 1, 2, the network cable twisted-pair feeder tester of band talkback unit comprises talkback unit and network cable twisted-pair feeder tester, and existing talkback unit and network cable twisted-pair feeder tester tester are improved, and it is combined into one; It mainly is end to be gone in the output of the antenna connection terminal of the wireless talkback circuit (known technology) of this talkback unit 1 and this network cable twisted-pair feeder tester 2 connect a frequency division multiplexing and multi-channel gating device, and the other end of frequency division multiplexing and multi-channel gating device is connected with the twisted-pair feeder interface 4 of tester.
This talkback unit 2 is different with the frequency that network cable twisted-pair feeder tester 3 is adopted.
This frequency division multiplexing and multi-channel gating device are made up of Hi-pass filter, low-pass filter, multichannel netting twine intercommunication switch 5 and multichannel netting twine Test Switchboard 6, and wherein: the antenna connection terminal of above-mentioned wireless talkback circuit connects multichannel netting twine intercommunication switch 5 by Hi-pass filter; The output of this network cable twisted-pair feeder tester is gone into end and is connect multichannel netting twine Test Switchboard 6 by low-pass filter, and the other end of this multichannel netting twine intercommunication switch 5 and this multichannel netting twine Test Switchboard 6 is corresponding and connect and then be connected (as shown in Figure 3) with the twisted-pair feeder interface 4 of tester.
This multichannel netting twine intercommunication switch 5 can be a hand switch with this multichannel netting twine Test Switchboard 6.It also can be automatic switch by microprocessor control.When being provided with microprocessor in talkback unit or the network cable twisted-pair feeder tester, this multichannel netting twine intercommunication switch and this multichannel netting twine Test Switchboard can be controlled by microprocessor.All be provided with microprocessor mostly in existing in general talkback unit or the network cable twisted-pair feeder tester, the microprocessor of the two can be replaced with one, under certain software arrangements, simultaneously talkback unit, tester and switch are controlled.
This talkback unit and network cable twisted-pair feeder tester are to be installed in the box body, on box body except that the various functional switches that are provided with tester, display screen, also be provided with pickup 7 and earphone jack 8, the pickup jack is electrically connected the input end of the input audio amplifier circuit of this wireless talkback circuit, and earphone jack is electrically connected the output terminal (shown in Fig. 1,2) of the output audio amplifying circuit of this wireless talkback circuit.
The utility model is that the antenna with talkback unit replaces with tested network cable line, according to the law of electromagnetic induction, when the magnetic flux that passes area that enclose the closed-loop path changes, to in the loop, produce induced electromotive force, when power transformation magnetic field exists when near the lead high frequency being arranged, the corresponding induced electromotive force and the corresponding induced current that in lead, will generate with the same frequency variation, and, form guided electromagnetic wave along wire spread.When conductor length was big, electric current because radiation and decay is gradually seldom reflected at end points, so was a kind of export-oriented damping row ripple in transmission course basically, so lead can be similar to and regards a long-line traveling-wave antenna as.For general communication frequency, 30 to 3000MHz, and respective wavelength is 10 to 0.1 meters, and when the radiation source yardstick is long for example between 10 meters to 100 meters, then tens meters scopes all should be calculated the near field.
Therefore when test, both sides need contact, and the calling party is inserted in the stube cable of tester in the network interface, and presses call button.Even at this moment both sides' distance is far away, or factor such as buildings internal cause wall causes shielding, when making wireless signal propagate into the other end, owing between the test both sides network cable is arranged, signal can propagate near the callee by cable, callee's tester ring this moment, the callee can answer by answering key.
