However, during testing and calibration, the wireless product under test may be the first tester, the retest is required for the previous test failure, and the retest is performed after the assembly error occurs at the back end of the production line and the repair is performed. Therefore, wireless products that have been writable to and unwritable to read only memory are mixed together for testing and calibration.
The traditional test method needs to classify tested wireless products which can be written into and can not be written into the read-only memory, and then selects a proper flow to test and correct.

Detailed Description
Embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawings, the same reference numbers indicate the same or similar elements or process flows.
FIG. 1 is a simplified functional block diagram of a test system 100 according to an embodiment of the present disclosure. The testing system 100 includes a first device 110, a second device 120, and a wireless device 130. The first device 110 is coupled to the wireless device 130, the second device 120 is coupled to the first device 110 and the wireless device 130, and the second device 120 is used for controlling the first device and the wireless device 130 to communicate with each other to test a signal receiving or transmitting function of the wireless device. The wireless device 130 includes a first read only memory 132 and a second read only memory 134, the first read only memory 132 and the second read only memory 134 being used to store data required for the operation of the wireless device 130. Wherein the second device 120 may utilize the first device 110 to perform an analysis of the signal transmission and reception functions of the wireless device 130.
In practice, the first device 110 may be a desktop computer, a notebook computer, a Field Programmable Gate Array (FPGA) or other devices with computing functions. The second device 120 may be an In-Phase/Quadrature (IQ) rf test instrument. The wireless device 130 may be any suitable device that is wireless network enabled and/or bluetooth enabled. The first device 110 may be coupled to the wireless device 130 through a radio frequency cable (radio frequency cable). The second device 120 may be coupled to the first device 110 and the wireless device 130 through an Ethernet cable (Ethernet cable).
FIG. 2 is a simplified flowchart of a testing method 200 according to an embodiment of the present disclosure. The test method 200 is suitable for use in the test system 100 and can be used to correct for signal transmission dysfunction of the wireless device 130. As shown in fig. 2, in the process S210, the second device 120 tests whether the signal receiving function of the wireless device 130 meets the standard by using the first device 110. For example, the second device 120 may control the first device 110 to transmit one or more received test packets to the wireless device 130, and then calculate a packet loss rate (packet loss rate) according to the number of the received test packets successfully received by the wireless device 130, so as to analyze the signal receiving function of the wireless device 130. If the signal receiving capability of the wireless device 130 meets the standard (e.g., the packet loss rate is lower than the predetermined threshold), the second device 120 performs the process S220, otherwise, the second device 120 determines that the test of the wireless device 130 fails.
In the process S220, the second device 120 may utilize the first device 110 to test whether the signal transmission function of the wireless device 130 meets the standard. For example, the second device 120 may control the wireless device 130 to transmit one or more transmission test packets to the first device 110, and control the first device 110 to parse the received transmission test packets to obtain the power and frequency of the transmission signal of the wireless device 130. If the second device 120 determines that the signal transmitting function of the wireless device 130 does not meet the standard (e.g., the power or frequency of the transmitted signal does not meet the predetermined value) and needs to be calibrated, the second device 120 performs the process S230. Otherwise, the second device 120 performs the process S240.
The process S220 may further include a process S222 of testing whether the frequency of the transmission signal of the wireless device 130 meets a predetermined frequency value, and a process S224 of testing whether the power of the transmission signal meets a predetermined power value. If the frequency of the transmitted signal does not meet the predetermined frequency value or the power of the transmitted signal does not meet the predetermined power value, the second device 120 determines that the wireless device 130 needs to perform calibration.
In flow S240, the second device 120 determines whether the first rom 132 of the wireless device 130 has stored any network addresses. If the first ROM 132 does not store any network address, the second device 120 knows that the wireless device 130 has not been tested by the testing method 200, and the first ROM 132 and the second ROM 134 can be written with new values. In this case, the second device 120 performs the process S250 to allocate a network address and write the network address into the first rom 132.
In the case where the second device 120 performs the process S220 first and then performs the processes S240 and S250, the signal transmitting and receiving functions of the representative wireless device 130 are standard-compliant and do not require further calibration. Therefore, in the process S250, the second device 120 further writes the preset power parameter and the preset frequency parameter into the first rom 132 and the second rom 134 of the wireless device 130, respectively, to set the power and the frequency of the transmission signal of the wireless device 130, so that the wireless device 130 generates the transmission signal according to the preset power parameter and the preset frequency parameter in the subsequent operation. The second device 120 then determines that the wireless device 130 has successfully tested.
On the other hand, if the second device 120 determines in the process S240 that the first rom 132 has stored the network address, the second device 120 knows that the wireless device 130 has passed the test of the test method 200 and reflowed from the back end of the production line and needs to be retested due to some factors. In this case, the second device 120 determines that the first ROM 132 and the second ROM 134 have stored the correct power and frequency parameters without writing new values. Therefore, the second device 120 does not write the network address, the preset power and frequency parameters to the wireless device 130. The second device 120 then determines that the wireless device 130 has successfully tested.
The aforementioned network Address may be a Media Access Control Address (Media Access Control Address). The predetermined power and frequency parameters may be stored in a flash memory (not shown) of the wireless device 130 in advance, so that the wireless device 130 can generate the transmission signal according to the predetermined power and frequency parameters during the test process for the second device 120 to determine. And the preset power and frequency parameters are not written into the first rom 132 and the second rom 134 by the second device 120, respectively, until the process S250.
In the case that the second device 120 determines that the wireless device 130 needs to be calibrated, the second device 120 determines whether the first rom 132 of the wireless device 130 stores any network addresses in the process S230. The step of determining whether the first rom 132 has stored any network address comprises: reading the data section of the first ROM 132; judging whether the data section cannot be read, whether a null value or a preset value exists or not; and if the data segment cannot be read, the null value is stored, or the preset value is stored, determining that the first rom 132 does not store any network address. If the second device 120 determines that the network address has been stored in the first ROM 132, the second device 120 knows that the wireless device 130 passed the test of the test method 200 and needs to be retested due to some factors in the back end of the production line. In this case, the second device 120 determines that the first rom 132 and the second rom 134 have accepted the value writing and cannot write new parameters for power or frequency correction. Therefore, the second device 120 determines that the wireless device 130 has failed in calibration.
On the other hand, if the first rom 132 does not store any network address, the second device 120 performs the process S260 to correct the power or frequency of the transmitted signal of the wireless device 130. In the process S260, if the second device 120 corrects the power of the transmission signal of the wireless device 130, the second device 120 correspondingly adjusts the predetermined power parameter, and if the second device 120 corrects the frequency of the transmission signal of the wireless device 130, the second device 120 correspondingly adjusts the predetermined frequency parameter.
Next, the second device 120 performs the process S270 to test whether the signal receiving function of the wireless device 130 meets the standard, and performs the process S280 to test whether the corrected signal transmitting function of the wireless device 130 meets the standard. If the signal transmission or reception function of the wireless device 130 does not meet the standard, the second device 120 determines that the wireless device 130 fails the test. If the signal transmitting and receiving functions of the wireless device 130 meet the standard, the second device 120 performs the aforementioned process S250 to write the preset/adjusted power parameter and the preset/adjusted frequency parameter into the first rom 132 and the second rom 134, respectively. In this way, the wireless device 130 can be ensured to meet the relevant legal standards.
The calibration process of the wireless device 130 will be further described with reference to fig. 3. Fig. 3 is a further detailed flowchart of the process S260 of fig. 2. In the process S310, the second device 120 determines whether the second rom 134 stores any frequency parameters. If the second rom 134 does not store any frequency parameter, the second device 120 performs the process S320 to modify the frequency of the transmission signal of the wireless device 130 and correspondingly adjust the predetermined frequency parameter. Next, the second device 120 executes the process S330 to instruct the first device 110 to analyze the transmission test packet sent by the wireless device 130 and report the result of the frequency correction to the second device 120, and the second device 120 then determines whether the corrected frequency matches a preset frequency value. If the modified frequency does not meet the predetermined frequency value, the second device 120 performs the process S340 to determine whether the frequency of the modified transmission signal is greater than or equal to a first predetermined frequency. If the frequency of the transmission signal is modified for a number of times greater than or equal to the first predetermined number of times, the second device 120 determines that the test of the wireless device 130 fails, otherwise, the second device 120 performs the aforementioned process S320 again to perform frequency calibration on the wireless device 130 again. If the modified frequency matches the predetermined frequency value, the second device 120 performs the process S350 to perform power calibration.
On the other hand, if the second device 120 determines in the process S310 that the second rom 134 already stores the frequency parameters, the second device 120 knows that the wireless device 130 has passed the test of the test method 200 and the second rom 134 can no longer write new parameters for frequency calibration. In this case, the second device 120 omits the related processes S320 to S340 of the frequency correction and directly executes the process S350.
In the process S350, the second device 120 modifies the power of the transmission signal of the wireless device 130 and adjusts the predetermined power parameter accordingly. Next, in the process S360, the second device 120 instructs the first device 110 to analyze the packet sent by the wireless device 130 and report the power correction result back to the second device 120, and the second device 120 then determines whether the corrected power matches a predetermined power value. If the modified power value matches the predetermined power value, the second device 120 performs the process S270 in fig. 2.
On the other hand, if the modified power does not meet the predetermined power value, the second device 120 performs the process S370 to determine whether the number of times of modifying the power of the transmitted signal is greater than or equal to a second predetermined number of times. If the power of the transmission signal is modified more than or equal to the second predetermined number of times, the second device 120 determines that the test of the wireless device 130 fails. If the number of times of modifying the power of the transmitted signal is less than the second predetermined number of times, the second device 120 performs the aforementioned process S350 again to perform power calibration on the wireless device 130 again.
Please note that, the flow charts of fig. 2 and fig. 3 are only exemplary embodiments, and are not intended to limit the embodiments of the present invention. In some embodiments, the order of power correction and frequency correction performed on wireless device 130 may be swapped. Therefore, the processes S350 to S370 may be performed first, and then the processes S310 to S340 may be performed.
In the foregoing embodiment, the frequency and power of the transmission signal of the wireless device 130 are determined by different control circuits (not shown in the figure). Therefore, the aforementioned power and frequency parameters are stored in the first rom 132 and the second rom 134, respectively. In embodiments where the frequency and power of the transmitted signal of the wireless device 130 are determined by the same control circuit, the aforementioned power and frequency parameters may be stored in the same ROM.
FIG. 4 is a simplified flowchart of a testing method 400 according to another embodiment of the present disclosure. The test method 400 is similar to the test method 200, except that the flows S210-S220 and S260 of the test method 400 test the wireless device 130 for signal transmission and reception with respect to wireless network transmissions, and the test method 400 additionally tests the wireless device 130 for signal transmission and reception with respect to Bluetooth transmissions.
Specifically, in the testing method 400, after the second device 120 performs the process S220 or S260, the process S410 is executed to test the bluetooth signal transmitting and receiving function of the wireless device 130. If the bluetooth signal transmitting or receiving function of the wireless device 130 does not meet the standard, the second device 120 determines that the test of the wireless device 130 fails. If the bluetooth signal transmitting or receiving function of the wireless device 130 meets the standard, the second device 120 then performs processes S240-S250 to determine whether to write the power and frequency parameters for the wireless network transmission and the power and frequency parameters for the bluetooth transmission into the wireless device 130.
Many of the processes and advantages of the testing method 400 are similar to those of the testing method 200, and for brevity, are not repeated here.
To summarize, when the second device 120 tests the signal receiving function of the wireless device 130, if the second device 120 determines that the signal receiving function of the wireless device 130 meets the predetermined standard, the second device 120 performs the operations of the aforementioned processes S220 to S280 to test the signal transmitting function of the wireless device 130 and correct the signal transmitting function of the wireless device 130 when the signal transmitting function is abnormal.
That is, when the second device 120 tests the signal transmitting function of the wireless device 130, if the second device 120 determines that the power of the transmitting signal of the wireless device 130 does not meet the predetermined power value or the frequency does not meet the predetermined frequency value, the second device 120 performs the operations in the aforementioned processes S230 to S280 to calibrate the power or the frequency of the transmitting signal of the wireless device 130.
On the other hand, if the second device 120 determines that the power and the frequency of the transmission signal of the wireless device 130 respectively conform to the preset power value and the preset frequency value, the second device 120 then performs the operations in the processes S240 to S250, or performs the operations in the processes S410 and S240 to S250, and does not perform the operations in the processes S230 and S260 to S280.
In view of the above, the test system 100, together with the test method 200 or 400, can distinguish the wireless products in which the rom can be written and the rom cannot be written by the same set of test procedures. Therefore, the test system 100 and the test methods 200 and 400 can reduce the error rate of the production line operation and improve the working efficiency of the production line.
