According to the method for calibrating the output power, the output power of the target object is calibrated based on the external measured value and the power difference value, wherein the power difference value is the difference value between the output power value of the target object and the preset power value.
In the embodiment of the application, the output power of the target object is calibrated based on the external measured value and the power difference value, the power difference value is the difference value between the output power value of the target object and the preset power value, and the output power of the target object is calibrated by using the external measured value and the power difference value without using external equipment to test the output power value repeatedly, so that the calibration efficiency can be improved.
A method of calibrating the output power of the target object based on the external measurement value and the power difference value will be described in detail below.
Fig. 1 schematically illustrates a method for calibrating output power according to an embodiment of the present application, which specifically includes the following steps:
s101, after a sending module and a receiving module in a target object are switched to a connection state, determining target configuration according to an internal measured value which is received by the receiving module and used for representing output power;
and S102, under the target configuration, calibrating the output power value of the target object based on the external measurement value and the power difference value.
Wherein the output power value of the target object comprises an output power value corresponding to the external measurement value in the target configuration.
In the embodiment of the application, a sending module and a receiving module of a target object are switched to a connection state, then a target configuration is determined according to an internal measurement value received by the receiving module and used for representing output power, and finally an output power value of the target object is calibrated under the target configuration based on the external measurement value and a power difference value.
The target object in the embodiment of the present application may be a chip, such as a radio frequency chip, or a module.
The present application will be described below with reference to a target object as a radio frequency chip.
In implementation, a Transmit (TX)/Receive (RX) switch inside the radio frequency chip may switch a TX module and an RX module inside the radio frequency chip to a connection state, that is, a connection state inside the radio frequency chip, and then turn on the TX module and the RX module, that is, the TX module may transmit a signal, and the RX module may receive the signal, and then determine a target configuration according to an internal measurement value received by the RX module for characterizing output power.
Specifically, the target configuration may be determined by first obtaining a maximum internal measurement value representing the output power, and then using a preset configuration corresponding to the maximum internal measurement value as the target configuration.
In the embodiment of the present application, the manner of obtaining the maximum internal measurement value representing the output power may be implemented by the following two manners:
the first method is that preset configuration parameters for controlling the output power of the TX module are automatically adjusted, the RX module keeps a receiving state, then internal measurement values received by the receiving module under each preset configuration are determined, the maximum internal measurement value is selected from the determined internal measurement values, and finally the preset configuration corresponding to the maximum internal measurement value is used as target configuration.
For example, there are 5 preset configurations, which are respectively a preset configuration a, a preset configuration B, a preset configuration C, a preset configuration D, and a preset configuration E, where the TX module outputs power under the control of each preset configuration, the RX module receives an RSSI (received Signal Strength Indicator) value of 1946 under the preset configuration a, an RSSI value of 1935 under the preset configuration B, an RSSI value of 1952 under the preset configuration C, an RSSI value of 1941 under the preset configuration D, an RSSI value of 1922 under the preset configuration E, and a maximum RSSI value of 1952, and then takes the preset configuration C as a target configuration.
For another example, the preset configuration includes 3 options, which are a, b, and c, and a fixed value may be set for the three options a, b, and c, and then each option is increased or decreased, and then any combination is performed to obtain multiple preset configurations, and then the measurement value received by RX is determined under each preset configuration, and then the preset configuration corresponding to the maximum measurement value is taken as the target configuration.
And in the second mode, the preset configuration parameters for controlling the output power of the TX module are automatically adjusted, the RX module keeps a receiving state, the internal measured values received by the RX module are compared due to the fact that the change rule of the internal measured values is parabolic, if the internal measured value before and after a certain internal measured value is smaller than the internal measured value, the internal measured value is used as the maximum internal measured value, and finally the preset configuration corresponding to the maximum internal measured value is used as the target configuration.
As shown in fig. 2, a schematic structural diagram of a TX module and an RX module in a connection state according to an embodiment of the present invention is provided. The TX module transmits a signal under the control of the configuration parameters adjusted by the RF control module, and the RX receives the signal to obtain an internal measurement value, and transmits a target configuration parameter corresponding to the maximum internal measurement value to an MCU (micro controller Unit).
The MCU terminal can store the target configuration parameters for use when the MCU terminal is powered on next time.
It should be noted that the measured value for characterizing the output power may be an RSSI value, and the RSSI value measured by the RX module is also a way to measure the power, and the unit thereof may be changed to be the same as the power value measured by the external instrument; configuration parameters may include LC filter trimming, Voltage-Controlled Oscillator (VCO) bias for optimum efficiency, etc.
After the target configuration is determined, a target measurement value may be obtained based on the external measurement value and the power difference value, and then, under the target configuration, an output power value obtained by adjustment, which corresponds to an adjustment value in which an error of the target measurement is within a preset range, is used as the output power value after calibration of the target object.
Specifically, the power difference may be determined first, and then the measurement value corresponding to the power difference may be obtained.
In the implementation, a measuring instrument capable of measuring an output power value can be connected to the outside of the radio frequency chip, then a TX/RX switch inside the radio frequency chip is switched to a TX module and RX module disconnection state and a TX module and measuring instrument connection state, then under a target configuration, an output power value of the radio frequency chip is measured by the external measuring instrument, a measured value corresponding to the output power value is used as an external measured value, and finally, the output power value measured by the external measuring instrument is subtracted from a preset power value to obtain a power difference value.
For example, the target configuration is configuration a, and in configuration a, the output power value of the radio frequency chip measured by the external measuring instrument is 7.5dbm, and the preset power value is 5dbm, then the power difference is 2.5 dbm.
Fig. 3 is a schematic structural diagram of a TX module and a measurement instrument connection according to an embodiment of the present invention. And the TX sends a signal, an external instrument measures the power value of the signal and sends the power value to the MCU.
It should be noted here that, since the external measurement value is measured in the target configuration, which is the preset configuration corresponding to the maximum internal measurement value, the external measurement value measured in the target configuration is the maximum external measurement value.
After the output power value of the radio frequency chip is measured by the external measuring instrument, the output power value can be fed back to the MCU, and the MCU makes a difference between the output power value and a preset power value to obtain a power difference value.
The preset power may be obtained through a large number of experiments, may be an empirical value, or may be a common practice in the industry, and the embodiment of the present application is not particularly limited.
And after the power difference value is obtained, obtaining a measured value corresponding to the power difference value, then subtracting the external measured value from the measured value corresponding to the power difference value, and taking the difference value as a target measured value.
In implementation, the measured value corresponding to the power difference value may be determined by a preset mapping relationship.
And after the target measurement value is obtained, under the target configuration, taking the output power value which is obtained by adjustment and corresponds to the adjustment value of which the error of the target measurement value is within the preset range as the output power value of the target object after calibration.
Specifically, a target adjustment value corresponding to a target measurement value is obtained, a target object is adjusted until an error between the adjustment value and the target adjustment value is within a preset range, an output power value corresponding to the adjustment value is output, and finally, the output power value corresponding to the adjustment value is used as the output power of the target object after calibration.
In specific implementation, the TX module and the RX module may be switched to a connection state, the TX module and the RX module are simultaneously turned on, an adjustment value of a transmission signal of the transmission module is adjusted and controlled, and when an error between the adjusted adjustment value and a target adjustment value is within a preset range, an output power value corresponding to the adjustment value is used as an output power value after calibration of the radio frequency chip.
The RSSI value is exemplified as the measured value.
For example, the maximum RSSI value is 1952, the output power value of the rf chip measured by the external measuring instrument is 7.5dbm, the preset power value is 5dbm, and the power difference is 2.5dbm, under the control of the target configuration, the RSSI value should be adjusted to 1932 (if the designed value 8 of the RSSI value is represented as 1dbm), and the difference between the maximum RSSI value and the target difference, which is 2.5dbm, is equal to the difference 2.5 × 8, which is 20.
In the embodiment of the present invention, a target gear position value corresponding to a target measurement value may be determined, then the TX module and the RX module are switched to the off state, and then a target output power of the radio frequency chip is determined under a target configuration and the target gear position value, and finally the target output power is used as the output power after calibration of the radio frequency chip.
Further, the target gear value may be saved, for example, the target gear value may be fed back to the MCU for saving, and the target gear value may be used when the rf chip is powered on next time.
In the finished product which is already produced in mass, the calibration of the secondary output power can also be carried out by the method for calibrating the output power provided by the application. Firstly, a relevant measuring instrument is connected to the outside of a radio frequency chip, a switch of an internal TX/RX is switched to a TX and an instrument which can measure radio frequency power outside the radio frequency chip, a specific value of the maximum value Pmax of the output power in the current state is measured, and then the maximum value Pmax is fed back to an MCU end through relevant interface communication. Feeding back the current output value to the inside, and calculating a difference value delta P between the Pmax and the target value Ptarget; and then switching the switch of the internal TX/RX to a connection state of the TX and the RX, adjusting the adjustment gear of the relevant TX output power, continuously testing a corresponding RSSI value as RSSI _ now by the RX module, when the difference value obtained by subtracting the RSSI _ now from the RSSI _ max is required delta P2, considering the corresponding power output gear as a required target value by calculating that the equivalent conversion delta P2 is the same as the delta P unit, and when the two values are consistent or approach within an error allowable range, saving the adjustment gear value of the relevant TX output power, sending the adjustment gear value to an MCU (microprogrammed control unit) end for saving, and using the configuration when the power is powered on next time.
Generally, after the output power of the radio frequency chip is calibrated when leaving a factory, secondary calibration cannot be carried out, and the adjustment of the output power value can be realized only by a mode of adjusting gears in batches, but because the conditions of each product are different, the final consistency is not ideal due to matching network difference on a path, device parameter errors and the like; the calibration mode can support secondary calibration, and internal adjustment is carried out in a mode of calculating a difference value by testing a current value and a target value, so that self-calibration is efficiently realized.
