FIG. 5 is a functional block diagram showing the outline of the measurement system according to the third embodiment, and FIG. 6 is a flowchart showing the operation of the measurement system. The measurement system will be described below with reference to FIGS. 5 and 6. The functional blocks similar to those of the measurement system according to the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 5, the measurement system measures a mobile communication terminal 10c such as a mobile phone terminal device, PHS, mobile information communication terminal device, wireless LAN, and ITS (automatic charge system) as an object to be measured. A section 1c is provided.

May be composed of a circulator, a duplexer, or the like.

Next, the operation of the measuring system will be described. In FIG. 5 and FIG. 6, the mobile communication device 10c in the state where the completion assembly process is completed is first performed as follows.
0c itself to enable operation, the mobile communication device 10c
The power source (not shown) of the internal battery mounted on the vehicle is turned on (step S31).

Next, the measuring section 1c is connected to the mobile communication device 10c.
A mobile communication device 1 using a communication method such as a packet method corresponding to
In order to enable communication with the mobile communication device 0c, a unique communication channel is assigned to the mobile communication device 10c that is the measurement target (step S32).

Next, the measuring section 1c includes the command output section 64
Transmits a measurement start command to the mobile communication device 10c (step S33). This is a communication method such as a packet method corresponding to the mobile communication device 10c, and the step S3 is performed.
It is transmitted via the transmitter 3, the switch 5, and the antenna 2 using the communication channel set in 2.

Then, the mobile communication device 10c receives the measurement start command transmitted in step S33, and brings the mobile communication device 10c into a measurable state (step S34).
The measurement start command is received by the antenna 11 via the wireless interface, and the command analysis unit 151 analyzes the command as a measurement start command via the switch 14 and the reception unit 13. After that, the command analysis unit 151 notifies the system control unit 153 of the start of measurement, and the system control unit 153 brings the mobile communication device 10c into a measurable state.

Next, the mobile communication device 10c notifies the measuring section 1c that the measurement is possible (step S3).
5). This is because the mobile communication device 10c transmits a command indicating the measurable state from the LOGIC unit 15c via the transmission unit 12c, the switch 14, and the antenna 11 in order to notify that the portable communication device 10c has entered the measurable state.

Then, the measuring unit 1c causes the above-mentioned step S35.
The notification of the measurable state transmitted by the control unit 6c is received.
(Step S36). This is the measuring unit 1c
However, the notification of the measurable state is received via the wireless interface, and is notified to the command analysis unit 62 via the antenna 2, the switch 5, and the receiving unit 4. Then, the command analysis unit 62 analyzes the command of the notification of the measurable state, so that the control unit 6c recognizes that the portable communication device 10c is in the measurable state.

Next, the measuring unit 1c transmits a notification of the default value of the control voltage output of the VCO 121 (step S).
37). This is because after the measuring unit 1c recognizes the measurable state of the mobile communication device 1c, the command output unit 64 outputs VC.
The notification of the default value of the control voltage output of O121 is transmitted via the transmission unit 3, the switch 5, and the antenna 2.

Then, the portable communication device 1c receives the notification of the default value transmitted in the above step S37, and D
The default value of the / A output unit 154 is set (step S38). This is because the mobile communication device 1c receives the notification of the default value transmitted in step S37 via the wireless interface, and the antenna 11 and the switch 1
4, sent to the command analysis unit 151 via the reception unit 13. After the notification analyzes the command in the command analysis unit 151, it is sent to the system control unit 153, and the system control unit 153 causes the D / A output unit 154 to set the default value of the output voltage based on the notification. Be instructed.

Next, the portable communication device 1c outputs the digital value of the default value of the output voltage of the D / A output section 154 set in the above step S38 to the D / A 155 (step S39), and the above default value. The RF signal is transmitted at a frequency based on (step S40). This is because the digital value of the default value of the output voltage of the D / A output unit 154 set in step S38 is output to the D / A 155, and the D / A 155 converts the digital value into an analog value. , The frequency control voltage of the voltage controlled oscillator VCO 121 is set to a default value. And V
The CO 121 transmits the RF through the switch 14 and the antenna 11 according to the frequency set by the default value.
Output a signal.

Next, the measuring unit 1c receives the RF signal output in step S40 via the wireless interface, and the measuring instrument 8 measures the frequency of the RF signal (step S41). The measuring unit 1c receives the RF signal at the antenna 2 via the wireless interface and sends the RF signal to the measuring instrument 8 via the switch 5. Then, the measuring instrument 8 measures the frequency of the received RF signal.

Next, the frequency measurement value of the RF signal measured by the measuring instrument 8 is sent to the control section 6c, and it is judged whether or not it is within a predetermined frequency range (step S42). This is because the frequency measurement value of the RF signal measured by the measuring instrument 8 is the control unit 6 via a measurement communication cable such as GP-IB.
Then, the control unit 6c determines whether the frequency measurement value is within a predetermined frequency range.

Then, in step S42, when the frequency measurement value is included in the predetermined frequency range, the measuring unit 1
The c transmits a pass notification to the mobile communication device 10c via the wireless interface, and stores a predetermined pass flag in a flash memory (not shown) provided inside the mobile communication device 10c (step S43). Then, the mobile communication device 10c is sent to the next step, and the flow ends.

On the other hand, when the frequency measurement value is not included in the predetermined frequency range in step S42, the control section 6 converts the difference between the frequency measurement value and the predetermined frequency range into the voltage value of the VCO 121. Then, the voltage value is transmitted again from the measuring unit 1c by the same method (step S
44), and returns to step S38. In this way, the output frequency of the mobile communication device 10c is repeated until it reaches the predetermined frequency range, and when the frequency reaches the above frequency range, the frequency adjustment ends. When the adjustment is not completed or the adjustment cannot be performed with the preset number of repetitions, the mobile communication device 1
0c is sent to the failure analysis process, where failure analysis is performed, measures such as component replacement are performed as necessary, and measurement and adjustment are performed again by the method described above.

Here, the VCO 121 of the portable communication device 10c according to the present embodiment is used as a power amplifier (PA: transmission output amplifier), the control voltage of the VCO 121 is adjusted to adjust the bias voltage of the PA, and the measuring instrument 8 is set to a power meter. The mobile communication device 10c is configured in the same manner as described above by configuring
It is possible to measure and adjust the output power of.

Further, in the case of a mobile communication device such as a mobile phone terminal device that has been used and collected, if the communication method is the same, the readjustment can be easily performed by adjusting the frequency and the output power by the above method. It can be reused.

As described above, the measuring unit to which the wireless interface unit is added measures the measurement and adjustment of the measured object having the wireless interface, and receives the adjustment instruction of the control voltage and the bias voltage from the measuring unit using the wireless interface. By transmitting to the measurement object, the output frequency and the output power of the measurement object can be measured and adjusted. Further, by using the wireless interface, the physical interface can be eliminated, the measurement and inspection process can be simplified, and the cost of the measurement system can be reduced.

In the description of the measurement systems according to the above-described first to third embodiments, various types of measurement are carried out, but among the measurement items of the measured object, there is a direct connection with the measured object. There are also items that must be measured. For example, when measuring the internal power supply of the object to be measured, that is, the DC system, the relationship between the initial value of the DC system and the amount of change in the power supply voltage due to the D / A output, which has not been adjusted, can be obtained only by the internal measurement application software. It is difficult to make an accurate determination. In such a case, the present invention can be applied by connecting an auxiliary measuring instrument, which can communicate by directly connecting to the serial communication unit provided in the measured object, to the measured object. That is, only the processing that requires measurement by direct connection such as DC system measurement is measured by the auxiliary measuring instrument directly connected to the DUT, and the measurement result is transmitted via the serial communication unit to the wireless interface as described above. The present invention can be similarly applied by being transmitted using.

For example, a user may obtain an interface protocol, adjust an object to be measured, or tamper with internal software to misuse it. Even if the data of the wireless interface is encrypted, the risk of being misused if the code is decrypted cannot be avoided. Further, even when the device under test is not the object to be measured and adjusted, it is possible that various functions are adjusted by receiving the above-mentioned command through the wireless interface. In order to avoid these risks, in the embodiment, the key function is used to prevent the internal software of the object to be measured from being tampered with or adjusted arbitrarily.

Data is transmitted from 53 via the communication unit 20 using an infrared communication interface.

Then, the measuring unit 1f causes the step S74 to be executed.
The notification of the measurable state transmitted in step S75 is received (step S75). This is because the measuring unit 1f receives the serial command indicating the measurable state at the communication unit 65 via the infrared communication interface, so that the control unit 6 can receive the serial command.
f recognizes that the mobile communication device 10f is in a measurable state.

Next, the measuring unit 1f transmits a notification of the default value of the control voltage output of the VCO 121 (step S).

And VC
The O121 outputs the RF signal via the antenna 11 according to the frequency set by the default value.

Next, the measuring unit 1f receives the RF signal transmitted in step S79 via the wireless interface, and the measuring instrument 8 measures the frequency of the RF signal (step S80). This is because the measurement unit 1f receives the RF signal with the antenna 2 via the wireless interface and sends it to the measuring instrument 8. Then, the measuring instrument 8 measures the frequency of the received RF signal.

Next, the frequency measurement value of the RF signal measured by the measuring instrument 8 is sent to the control section 6f, and it is judged whether or not it is within a predetermined frequency range (step S81). This is because the frequency measurement value of the RF signal measured by the measuring instrument 8 is the control unit 6 via a measurement communication cable such as GP-IB.
Then, the controller 6f determines whether the frequency measurement value is within a predetermined frequency range.

Then, in step S81, if the frequency measurement value is included in the predetermined frequency range, the measuring unit 1
f transmits a pass notification to the mobile communication device 10f through the infrared communication interface, and stores a predetermined pass flag in a flash memory (not shown) provided inside the mobile communication device 10f (step S82). . Then, the mobile communication device 10f is sent to the next step, and the flow ends.

Then, using the infrared communication interface in the same manner, the measuring unit 1f is calculated again.
The above voltage value is transmitted from (step S83), and the process returns to step S77. In this way, the output frequency of the mobile communication device 10f is repeated until it reaches the predetermined frequency range, and when the frequency reaches the above-mentioned frequency range, the frequency adjustment ends. When the adjustment is not completed or the adjustment cannot be performed with the preset number of repetitions, the mobile communication device 10f is sent to the failure analysis step, the failure analysis is performed, and the parts are replaced as necessary. The measurement and adjustment are performed again by the method described above.
