It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In an embodiment, as shown in fig. 1, the WiFi non-signaling test method provided by the present application includes steps S110 to S140.
In step S110, the current digital gain value is set to a first value.
In the non-signaling test of the WiFi chip, a QSPR tool is installed on a control terminal, the control terminal is connected with a tested device, a current digital gain value is set through the QSPR tool, and the tested device is controlled to transmit a WiFi signal according to the current digital gain value; in this embodiment, the initial digital gain value is set to a first value.
And step S120, controlling the tested device to transmit a WiFi signal according to the current digital gain value, and obtaining a WiFi performance index of the WiFi signal. The WiFi performance index comprises a first performance index and at least one second performance index.
In one embodiment, the first performance metric includes WiFi power; the second performance index includes: error Vector Magnitude (EVM), frequency error. In other embodiments, the second performance may include other WiFi transmission indicators.
In one embodiment, controlling the device under test to transmit a WiFi signal at the current digital gain value comprises: and controlling the tested equipment to perform digital-to-analog conversion on the current numerical gain value, and transmitting a WiFi signal by the WiFi chip according to an analog signal obtained by converting the current digital gain signal.
In one embodiment, obtaining a WiFi performance indicator for a WiFi signal comprises: and receiving the WiFi signal transmitted by the tested equipment through the test instrument, and reading the WiFi performance index returned by the test instrument by the QSPR tool on the control terminal. In a specific embodiment, the test instrument sends the WiFi performance index to the QSPR of the control terminal, and the QSPR determines whether the WiFi performance of the device under test is qualified according to whether the performance index is within a corresponding preset index range.
And S130, when the first performance index is out of the first preset index range, adjusting the current digital gain value to a second numerical value based on the first performance index, and returning to the step of controlling the tested device to transmit the WiFi signal according to the current digital gain value.
In this embodiment, the adjusted digital gain value is recorded as a second numerical value.
In one embodiment, adjusting the current digital gain value to the second value based on the first performance metric comprises:
if the first performance index is smaller than the minimum value of the first preset index range, increasing the current digital gain value to a second value; and if the first performance index is larger than the maximum value of the first preset index range, reducing the current digital gain value to a second value.
Further, increasing the current digital gain value to a second value includes: adding one to the current digital gain value to obtain a second value; reducing the current digital gain value to a second value, comprising: and subtracting one from the current digital gain value to obtain a second numerical value.
In other embodiments, the current digital gain value may be adjusted by increasing or decreasing other values each time. In this embodiment, each time the value of the current digital gain value is adjusted to be 1, for example, 1 is added to the current digital gain value, so that it can be avoided that the WiFi power detected by the adjusted digital gain value correspondingly exceeds the maximum value of the preset power index range.
In one embodiment, the first preset index range includes a preset power index range, and the preset index range may be set according to actual conditions. In one embodiment, taking the WiFi rate as 11b as an example, the first value is 15, and the preset power index range may be 13dbm to 18 dbm; in this embodiment, when the device under test is controlled to transmit the WiFi signal with the digital gain value of 15 and the WiFi power in the obtained WiFi performance is less than 13dbm, the current digital gain is adjusted from 15 to 16, and the step of controlling the device under test to transmit the WiFi signal with the current digital gain is returned.
And step S140, when the first performance index is within the first preset index range, determining whether the WiFi performance of the tested equipment is qualified or not based on each second performance index.
In one embodiment, determining whether the WiFi performance of the device under test is qualified based on the second performance indicators includes: if the second performance indexes are within the second preset index range, determining the WiFi performance of the tested equipment to be qualified; and if the second performance indexes are out of the second preset index range, determining that the WiFi performance of the tested equipment is unqualified.
In one embodiment, the second predetermined index range includes a predetermined error vector magnitude index range and a predetermined frequency error index range. Still taking the WiFi rate as 11b for example, the first value is 15, and the predetermined power index range may be 13dbm to 18 dbm. And when the WiFi power in the WiFi performance indexes is detected within the range of 13-18 dbm at any time, judging whether each second performance index is within the corresponding preset index range, if so, determining that the WiFi performance of the tested equipment is qualified, and otherwise, determining that the WiFi performance of the tested equipment is unqualified.
The WiFi non-signaling test method comprises the steps of firstly, controlling tested equipment to transmit WiFi signals through current digital gain, obtaining WiFi performance indexes of the WiFi signals, returning to control the tested equipment to transmit the WiFi signals after adjusting the current digital gain when a first performance index in the WiFi performance indexes is out of a first preset index range, and detecting the performance indexes of the WiFi signals again. And when the first performance index is within the first preset index range, determining whether the WiFi performance of the tested equipment is qualified or not by combining with the second performance index. By the method, when the WiFi chip is screened, when the first performance index is not within the first preset index range, the digital gain is adjusted to repeatedly detect the WiFi performance index of the tested equipment, so that the WiFi chip with poor consistency in the tested equipment is prevented from being screened as a bad chip on the premise of not changing the preset standard range.
In one embodiment, as shown in fig. 2, the method further includes step S210: and when the first performance index is out of the first preset index range and the adjusting times of the current digital gain value reach preset times, determining that the WiFi performance of the tested equipment is unqualified.
In this embodiment, the number of times of adjusting the digital gain is recorded every time the digital gain is adjusted. When the number of times of adjusting the digital gain reaches the preset number of times, but the detected WiFi power in the WiFi performance is still outside the preset power index range, the digital gain is not continuously adjusted, and the WiFi performance of the tested device is determined to be unqualified.
The preset times can be set according to requirements. In one embodiment, the preset times are set to 3 times, so that the requirement of detecting a WiFi chip with poor consistency can be met, and excessive time is not spent, so that the WiFi non-signaling test method in the embodiment of the application is shorter in the time spent on increasing the test compared with a method of detecting only once.
As shown in fig. 3, which is a schematic flowchart illustrating a procedure of a WiFi non-signaling test method in a specific embodiment of the present application, the WiFi non-signaling test method is applied to a WiFi non-signaling test system, and the system includes a control terminal and a test instrument. In this embodiment, the control terminal is a pc (personal computer) for example; and a high-pass QSPR tool is installed at the PC end. The PC is connected with the test instrument through a GPIB (General-Purpose Interface Bus), the test instrument is controlled through the GPIB line, and the power value returned by the instrument is read; the PC is connected with the tested equipment through a USB wire, and the tested equipment is controlled through QSPR; the testing instrument is connected with the tested device through a testing line.
When the device to be tested is tested, the initial digital gain value of the transmission is set to 15 by taking the WiFi rate as 11b as an example. Setting a current digital gain at a PC end, controlling the tested equipment to perform digital-to-analog conversion, enabling a WiFi chip of the tested equipment to transmit a WiFi signal by the current digital gain (15), sending the WiFi signal to a test instrument through a test line, reading a WiFi performance index of the tested equipment by the test instrument, and transmitting data to a QSPR tool at the PC end through a GPIB. QSPR judges whether the WiFi performance index is in the corresponding preset index range.
And judging whether the WiFi power in the WiFi performance index is within a preset power index range, if not, adjusting the digital gain value by the QSPR according to the WiFi power, and returning to the step of controlling the tested equipment to perform digital-to-analog conversion to transmit the WiFi signal. In this embodiment, the preset power index range is 13dbm to 18dbm, if the detected WiFi power is less than 13dbm, the QSPR controls the digital gain to increase by 1 to 16, controls the WiFi chip of the device to be tested to transmit a WiFi signal with the digital gain of 16, and then reads and detects the WiFi performance index. If the detected WiFi power is larger than 18dbm, the QSPR controls the digital gain to be reduced by 1 to 14, and then detects the WiFi performance index of the tested device for transmitting the WiFi signal with the digital gain 16. After the digital gain value is adjusted, the method also comprises the step of recording the times of adjusting the digital gain.
If the WiFi power in the WiFi performance indexes is within a preset power range, judging whether other indexes (EVM, frequency error and the like) in the WiFi performance indexes are within respective corresponding preset index ranges, and if so, determining that the WiFi performance of the tested equipment is qualified; and if not, determining the WiFi performance of the tested device to be unqualified.
If the WiFi power read after the digital gain is adjusted in the WiFi performance index is out of the preset power range, the digital gain value is continuously adjusted, whether the number of times of adjusting the digital gain value is larger than the preset number of times is judged, if not, the step of controlling the tested equipment to transmit WiFi signals is returned, and the WiFi performance index is continuously detected. And if the times of adjusting the digital gain are greater than the preset times, directly determining that the WiFi performance of the tested equipment is unqualified. In this embodiment, the preset number of times is set to 3, and taking the WiFi power detected by the initial digital gain 15 corresponding to the WiFi power smaller than 13dbm as an example, that is, the digital gain value is adjusted from 15 to 18 at most, and if the test fails, the WiFi performance of the device under test is determined to be unqualified.
By the method, the WiFi chips with poor consistency can be screened, namely, the control on the production quality of the WiFi chips is more strict, the hardware cost is not required to be increased, and in addition, repeated tests are required to be added only for a few WiFi chips with poor consistency, so the increased test time cost of the whole method is less.
It should be understood that, although the steps in the flowcharts of fig. 1 to 3 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows.

And when the first performance index is out of the first preset index range, adjusting the current digital gain value to a second numerical value based on the first performance index, and returning to the step of controlling the tested equipment to transmit the WiFi signal by using the current digital gain value.
When the first performance index is within the first preset index range, the control terminal 420 determines whether the WiFi performance of the device under test is qualified based on each second performance index.

And when the WiFi power in the read WiFi performance indexes is out of the preset power range after the digital gain is adjusted, and the times of adjusting the digital gain value reach the preset times, the WiFi performance indexes are not tested in a circulating mode, and the WiFi performance of the tested equipment is determined to be unqualified.
