In order to simplify the description, in the example illustrated in FIG. 4, the terminal device 30 (30-1 to 30-M: M is a natural number) as a measurement target has two antenna units. The number of parts is not limited to this.

And a half-duplex communication terminal that can be connected to an antenna unit that performs half-duplex communication.

  The signal generation unit 22 includes a baseband signal generation unit 22a and an RF modulation unit 22b. Based on a predetermined clock, the baseband signal generation unit 22a generates an I component baseband signal and a Q component baseband signal that is an orthogonal component signal whose phase is shifted by π / 2 from the I component baseband signal. It has become.

  These baseband signals include control information necessary for the measurement module 10 to function as a pseudo base station for the terminal device 30. The control information includes, for example, instructions necessary for location registration, incoming call, disconnection, and other tests exchanged between the terminal device 30 and the pseudo base station.

  The RF modulation unit 22b generates a test signal corresponding to the frequency of each communication standard by mixing the baseband signal received from the baseband signal generation unit 22a with a local signal corresponding to the frequency of each communication standard, The generated test signal is output to the terminal device 30 connected to the terminal device connection unit 21.

  The signal analysis unit 23 receives the local signal from the RF modulation unit 22b, orthogonally demodulates a response signal or a transmission signal (hereinafter referred to as a terminal transmission signal) from the terminal device 30, and performs an I component baseband signal and a Q component. After conversion into baseband signals, the baseband signals are decoded and analyzed for measurement. For example, the signal analysis unit 23 may be capable of performing modulation accuracy measurement, adjacent channel leakage power measurement, power measurement, and the like.

  That is, the signal analysis unit 23 receives a response signal from the terminal device 30 with respect to the test signal or a terminal transmission signal from the terminal device 30, and uses the response signal or the terminal transmission signal to communicate with the terminal device 30. The above-mentioned measurement is performed.

  The switching unit 24 selectively selects the antenna units 30-1a to 30-Ma and 30-1b to 30-Mb of the plurality of terminal devices 30 to the signal generation unit 22 and the signal analysis unit 23 via the terminal device connection unit 21. Or selectively connected to either one of the signal generation unit 22 and the signal analysis unit 23.

  The control unit 25 causes the signal generation unit 22, the signal analysis unit 23, and the switching unit 24 to perform processing corresponding to one of a plurality of communication standards. Specifically, the control unit 25 causes the signal generation unit 22 to generate a test signal corresponding to any one of the plurality of communication standards, and causes the signal analysis unit 23 to correspond to any one of the plurality of communication standards. The analysis process is performed. The external control device 100 can be connected to the control unit 25 via the interface unit 11 and the chassis connection unit 26.

  In addition, the control unit 25 stores a program for controlling the signal generation unit 22, the signal analysis unit 23, and the switching unit 24 corresponding to the communication standard of the terminal device 30 in the memory 25a in advance. The control unit 25 can receive a new program or a program whose version has been changed from the outside, and can add or update the memory 25a.

  Furthermore, the memory 25a stores in advance a correction value for the loss of the wiring inside the measurement module 10, and the signal analysis unit 23 can correct the analysis result using the correction value.

  Further, the measurement module 10 may include a reception signal analysis unit (not shown) that measures the reception function of the terminal device 30 with respect to the test signal from the signal generation unit 22. Furthermore, the measurement module 10 may include a determination unit (not shown) that determines whether or not the measurement value satisfies a predetermined standard. This determination is performed, for example, by evaluating the magnitude relationship between a predetermined threshold value and the measured value, or the output levels of the antenna unit 30-ma and the antenna unit 30-mb (m = 1,..., M). Or by evaluating the difference in reception sensitivity.

Hereinafter, the measuring method of the terminal device 30 using the measuring apparatus 1 of this embodiment is demonstrated.

  Next, the external controller 100 and the measurement module 10 are connected by the cable 18 by the operator (connection stage).

  For example, in the configuration in which the external control device 100a controls the measurement module 10-1 and the external control device 100b controls the measurement modules 10-2 to 10-4 as shown in FIG. 1, the measurement module 10-1 and the external control device 100 a are connected by a connector.

  Further, the terminals 15-2 to 15-4 of the module side terminal portion are connected to the terminals 16-2 to 16-4 of the input side terminal portion, respectively, and the terminal 17a (or 17b) of the output side terminal portion is externally connected. The connector 19 is connected to the external control device 100b through the hub 19.

  Next, each external control device 100 assigns an IP address to the measurement module 10. In the example shown in FIG. 1, since one external control device 100b controls the plurality of measurement modules 10-2 to 10-4, it is necessary to assign different IP addresses to the plurality of measurement modules 10-2 to 10-4. There is.

  In the configuration of FIG. 1, for example, “192.168.1.1” is assigned as an IP address to the measurement module 10-1 by the external control device 100a, and the measurement modules 10-2 to 10-4 are assigned by the external control device 100b. “192.168.1.2”, “192.168.1.3”, and “192.168.1.4” are respectively assigned as IP addresses. Note that there is no problem in control even if the IP address of the measurement module 10-1 is the same as any of the IP addresses of the measurement modules 10-2 to 10-4.

Here, a case where one measuring apparatus 1 performs an examination on different communication standards (for example, cellular, WLAN, GNSS, and FM radio broadcasting) for a plurality of terminal devices 30 will be described as an example. The operator can select a communication standard to be inspected from a plurality of communication standards by using the operation unit 110 of the external control device 100.

  First, the control unit 25 of each measurement module 10 included in the measurement apparatus 1 transmits an instruction signal instructing a communication standard (cellular, WLAN, GNSS, and FM radio broadcast) to be inspected from the corresponding external control apparatus 100. It is confirmed that the measurement function of each measurement module 10-1 to 10-4 is set to one corresponding to cellular, WLAN, GNSS, and FM radio broadcasting.

  Then, a plurality of terminal devices 30 are connected to the respective terminals 21-1a to 21-Ma and 21-1b to 21-Mb of the respective measurement modules 10 of the measuring apparatus 1 by the operator.

  The control unit 25 of the measurement module 10 sends an instruction signal to the signal generation unit 22 and the switching unit 24 toward the antenna unit of the terminal device 30 connected to each terminal of the measurement module 10. A test signal corresponding to GNSS and FM radio broadcasting is output.

  Next, the control unit 25 sends an instruction signal to the signal analysis unit 23 and the switching unit 24, analyzes the response signal or terminal transmission signal from the antenna unit of each terminal device 30 with respect to the test signal, and the analysis result Is stored in the memory 25a. At this time, it is assumed that the control unit 25 notifies the signal analysis unit 23 of the correction value of the loss of the internal wiring stored in advance in the memory 25a.

  The terminal device 30 for which measurement has been completed is sequentially detached from the terminals 21-1a to 21-Ma and 21-1b to 21-Mb of the measurement module 10 by the operator. New terminal devices may be sequentially attached by the operator to the terminal from which the terminal device 30 has been removed.

  As described above, according to the present embodiment, a plurality of measurement modules 10 can be connected to one or more external control devices 100 via the hub 13, while one measurement module 10 is not connected via the hub 13. It is also possible to connect the external control device 100 one by one.

  Further, according to the present embodiment, the connection method between the external control device 100 and the measurement module 10 can be freely changed. In particular, when the hub 13 breaks down, it is possible to avoid a situation in which all of the plurality of measurement modules cannot be used by connecting one external control device 100 to each measurement module 10.

  Further, according to the present embodiment, when the number of terminals 16 of the input side terminal portion is equal to or larger than the maximum number of measurement modules 10 that can be accommodated by the chassis 12, the maximum number of measurement modules 10 is included in one measurement apparatus. Even if all of them are connected to the external control device 100 via the hub 13, the measurement module of another measurement device is connected to the input side terminal portion of the one measurement device, and the same external control is performed. Control by the apparatus 100 is possible.

  Further, according to the present embodiment, since any number of measurement modules 10 capable of changing the measurement function by software can be arranged in the chassis 12 according to the measurement contents, the terminal device 30 It becomes possible to construct a measuring device according to the form of the production line.

  In addition, according to the present embodiment, since the display unit 120 of the external control device 100 can be connected via the interface unit 11, the analysis results output from the plurality of measurement modules 10 are combined into one monitor. It is possible to display them collectively, and it is possible to realize space saving of the arrangement area of the apparatus and cost reduction of the apparatus.
