Description
Technical Field
The invention relates to the field of communication measurement, in particular to a one-stop full-automatic radio frequency device testing system.
Background
The environment adaptation requirements of communication systems to communication equipment are higher and higher, and the design and manufacture of the communication industry also face a large number of test measurement and data acquisition tests. For example, radio frequency wireless communications require filters to remove out-of-band signals and interference. In this process, the target signal is distorted by the filter, resulting in an increase in the error rate. This requires filters with low in-band insertion loss and in-band ripple, and high out-of-band rejection, thereby reducing signal distortion. The increase in the filter index makes the debugging of the filter more and more difficult.
To manufacture a high performance filter, debugging is more important than design. Because the inductance of the coils in the filter is difficult to accurately test, various factors (collectively referred to as parasitic parameters) such as turn-to-turn capacitance, contact capacitance, and mutual inductance between the coils can cause a large difference between the characteristics of the actually manufactured filter and the characteristics expected during design. The effects and errors caused by these parasitic parameters must be adjusted to compensate.
The traditional filter test adopts a pipeline working mode, each post is only responsible for one test item, and generally, one filter finishes 3-8 unequal test procedures which are probably required to be converted for all the test items according to different test indexes, so that the following problems can be caused:
the circulation efficiency is not high, although the assembly line test is nominally adopted, in practice, because each test needs manual insertion of the instrument, the work station and the work station are still transferred by manpower and are not connected by an automatic assembly line, the real flow type operation cannot be realized, and the whole test efficiency is low
The outward appearance that causes in the transportation damage even performance, because the metal cavity is comparatively heavy, and the surface is irregular, and consider that the efficiency problem often can pile up to a certain amount after with the vehicle transport to next test station, because the operation among the operation process is improper or the protection is not in place, often can cause the collision and the lamination of metal cavity, light then the outward appearance collides with the damage, heavy then thoroughly destroys the performance index.
The line balance configuration is not good, because the testing time of each work station is different, the line balance needs to be configured to achieve or approach the pipeline type testing efficiency, the testing requirements of filters of various types are not consistent, the line balance configuration needs a large amount of instrument investment, the equipment connection is complicated, and the equipment cannot be changed easily, so the existing line balance configuration can only rely on past experience to compromise the equipment investment and the testing efficiency.
The consistency difference of the instruments is obvious, each work station needs to be configured with a vector network analyzer and other measuring instruments, the seamless connection between the work stations is based on the measurement error alignment between the instruments, although the daily calibration can meet the requirement of daily test, the problem cannot be thoroughly solved, and frequent calibration consumes manpower and time.
The connector is obvious in use loss, and as the connector is circulated to each work station and needs to be re-plugged with the instrument and the workpiece and is used as a component of a test link, all the connectors have verified service life regulations (less than or equal to 500 times), the overrun use not only brings hidden danger to measurement, but also has more limited connector loss which can be really saved.

13. The method of claim 9, wherein the programming step includes setting the signal switching unit to include one or more of an S-parameter test, a high power test, an intermodulation test, a leakage test, and a low reflection load test.
14. The radio frequency device testing method according to claim 9,
in the step of obtaining the result, the test instrument unit feeds back the test result to be displayed on the test instrument, or sends the test result back to the main control unit.
15. The radio frequency device testing method according to claim 12,
when the test result is sent back to the main control unit, the test result is sent to the remote receiving terminal through a wired or wireless communication mode.
16. The method of claim 9, further comprising, after the obtaining step:
and a processing step, namely judging whether the test item is the last test item or not by the main control unit, terminating the test if the test item is the last test item, processing the final test result, and entering the testing step if the test item is not the last test item.
17. A method for radio frequency device testing using the radio frequency device testing system of any one of claims 1-10, the method comprising the steps of:
setting the type of a device to be tested, test items and a test sequence of the test items on a remote terminal, and sending a test message to a test message transceiving module of a radio frequency device test system;
the test message receiving and sending module sends the received test message to a main control unit, and the main control unit loads a test instruction and starts a test flow;
and the main control unit sends the test result to the remote test terminal.
18. A radio frequency device testing remote terminal for use with the radio frequency device testing system of any one of claims 1-10, wherein the remote terminal comprises:
the setting module is used for setting the type of a device to be tested, test items and the test sequence of the test items; the sending module is used for sending the test message to a test message receiving and sending module of the radio frequency device test system;
and the receiving module is used for receiving the test result sent by the test message receiving and sending module.
19. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out the steps of one of the claims 9 to 14.
