s201: and acquiring target compensation calibration data corresponding to the target switch channel.

S202: and controlling the test unit to test and/or calibrate the target test port according to the target compensation calibration data through the target switch channel.

In this embodiment, there is only one common rf connector, so when testing and/or calibrating the test ports, it is necessary to test and/or calibrate each test port through different switch channels, and the corresponding transmission links are different. However, due to the influence of factors such as the length of the wires in the transmission link and the radian of the wires, the transmission links are different, and the loss of each test port in the test and/or calibration process is also different. Therefore, the transmission loss difference corresponding to different switch channels can be predetermined and used as compensation calibration data of the switch channel, and then when the test unit is controlled to test and/or calibrate the target test port through the target switch channel, the target compensation calibration data corresponding to the target switch channel is obtained first, and then the test unit is controlled to test and/or calibrate the target test port according to the target compensation calibration data through the target switch channel.

Optionally, assuming that the switch is a DPDT switch, the antenna without the rf connector is a second antenna, and the antenna with the rf connector is a first antenna, since the impedance line states from the two antennas to the DPDT switch are different, the signal loss is also different. Optionally, when the ornament is in a development stage, the measured power of the rf connector corresponding to the first antenna is 24dBm, since the second antenna has no rf connector, a coaxial line needs to be temporarily welded at the second antenna, and then the measured power of the coaxial line is 22dBm, so that a difference value of 2db is obtained, that is, the compensation calibration data corresponding to the target switch channel is 2 db. In the actual mass production stage, when the target switch channel is controlled to be switched on, the control end can control the test unit to test and/or calibrate the target test port according to the compensation calibration data 2db through the target switch channel.

The accuracy of the calibration of the test port is improved by combining the compensation calibration data to test and/or calibrate the test port.

Optionally, before the S10, the method may further include: and acquiring actual loss values corresponding to input ports in the switch and reference loss values corresponding to switch channels. And performing difference processing on the reference loss value and the actual loss value to obtain compensation calibration data corresponding to each switching channel.

Optionally, when determining the compensation calibration data corresponding to each switch channel, an actual loss value corresponding to each input port in the switch may be determined first, that is, a loss value measured when each input port is connected to a radio frequency connector or a radio frequency test socket. And then determining a reference loss value corresponding to each switch channel, namely determining a loss value corresponding to an input port when only one input port is connected with the radio frequency connector. And performing difference processing on the reference loss value and each actual loss value to obtain compensation calibration data corresponding to each switch channel.

Optionally, the switch has three input ports A, B, C, with input port a having an actual loss value of 24dBm, input port B having an actual loss value of 23dBm, and input port C having an actual loss value of 22 dBm. In practical application, the radio frequency connector is connected to the input port C, and the reference loss value corresponding to each switch channel is 22dBm, so that the compensation calibration data of the switch channel corresponding to the input port a is 24dBm-22 dBm-2 dBm, and the compensation calibration data of the switch channel corresponding to the input port B is 23dBm-22 dBm-1 dBm.

Optionally, after the S20, the method may further include: receiving a calibration abnormity prompt sent by the test unit, and judging whether the times of the calibration abnormity prompt exceed a preset time threshold value; if the number of times of the abnormal calibration prompt does not exceed the preset number threshold, executing the step S10 again; and if the times of the abnormal calibration prompt exceed a preset time threshold, outputting a calibration failure prompt.

In this embodiment, during the process of testing and/or calibrating the test port by the test unit, an abnormality may occur in the test process or the calibration process due to a transmission link or a network failure, and in order to ensure normal implementation of the calibration process and the test process, a calibration abnormality prompt may be sent to the control terminal when the calibration process or the test process is abnormal. After receiving the calibration abnormal prompt, the control end can further process according to whether the frequency of the abnormal prompt exceeds a preset frequency threshold value. Optionally, when the number of times does not exceed the number threshold, the target calibration instruction may be sent to the radio frequency unit again, so that the radio frequency unit controls the target switch channel to be turned on, and controls the test unit to test and/or calibrate the target test port through the target switch channel. If the number of times exceeds the threshold value, a calibration failure prompt is output, the situation that the cyclic judgment is always carried out is avoided, and the timeliness and the accuracy of calibration are improved.

Third embodiment

The S10 may include: determining the calibration sequence of each test port according to a calibration rule; determining or generating calibration instructions for the test ports according to the calibration sequence, and executing the step S10 according to the calibration instructions in sequence.

In this embodiment, when calibrating each test port, a calibration order of each test port may be determined according to a calibration rule, then a calibration instruction for the test port is determined or generated according to the calibration order, and a target calibration instruction is sequentially sent to the radio frequency unit according to the calibration instruction, so that the radio frequency unit controls the target switch channel to be turned on, and controls the test unit to test and/or calibrate the target test port through the target switch channel.

In one implementation, the calibration rule may be a random calibration rule, that is, the test ports may be randomly tested and/or calibrated without limiting the calibration order of the test ports. For example, assuming that there are two test ports, namely a first test port and a second test port, the first test port may be calibrated first, and then the second test port may be calibrated. The second test port can be calibrated firstly, then the first test port is calibrated, and the flexibility and convenience of calibration are improved in a mode of not limiting the port calibration sequence.

In another implementation, if the calibration rule is calibration according to the type of the test port, the S20 may include: and if the number of the switch channels is at least two, controlling the test unit to test and/or calibrate the first target test port through the first target switch channel.

Optionally, after the testing and/or calibration of the first target test port is completed, the testing unit is controlled to sequentially test and/or calibrate at least one second target test port through a second target switch channel, where port types of the first target test port and the second target test port are different.

Illustratively, the first target test port is a 5G type port, the second target test port is a 4G type port, and the second target test port is at least one, and the calibration rule is to calibrate the 5G type port first and then calibrate the 4G type port, so that the test unit may be controlled to test and/or calibrate the first target test port through the first target switch channel, and after the test and/or calibration of the first target test port is completed, the test unit may be controlled to test and/or calibrate at least one second target test port sequentially through the second target switch channel.

In addition, the present application only lists a few specific ways of determining the calibration order, and other ways of determining the calibration order are within the scope of the present application.

Optionally, the S20 may include: if the number of the switch channels is at least two, controlling the test unit to test and/or calibrate the first target test port through the first target switch channel; after the first target test port is tested and/or calibrated, the test unit is controlled to sequentially test and/or calibrate at least one second target test port through a second target switch channel.

In this embodiment, the switch types corresponding to different numbers of test ports are different, and if there are two test ports, that is, one first target test port and one second target test port, the switch type is NPNT (N Pole N through, N Pole N through switch), the first target test port may be tested and/or calibrated through the first target switch channel, and the second target test port may be tested and/or calibrated through the second target switch channel.

Alternatively, if there are three test ports, i.e., a first target test port and two second target test ports, and the switch type is 3P3T (3Pole 3 thru, three Pole three Throw switch), the first target test port can be tested and/or calibrated through the first target switch channel, and the remaining two second target test ports can be tested and/or calibrated through the second target switch channel. Alternatively, the number of second target test ports may be more than two, for example, three, five, etc., which are not listed in detail herein.
