Description

Technical Field

[0001] This invention relates to the field of combined power testing, specifically to a power testing system and method for multi-channel combined circuits. Background Technology

[0002] In existing multi-channel combined power testing methods, the testing equipment is highly sensitive to environmental temperature and humidity. For example, in environments with large day-night temperature differences or high humidity, the performance of the testing equipment will drift significantly due to environmental fluctuations, resulting in inaccurate power measurement results. Existing solutions only correct the effects of temperature and humidity through linear compensation, while ignoring the coupling effects between temperature and humidity, such as the increased nonlinear insertion loss in high temperature and high humidity environments, which cannot completely eliminate the errors caused by environmental fluctuations.

[0003] In addition, the testing equipment will experience aging during long-term use, which will lead to a decrease in its sensitivity or drift of the bias voltage. Existing methods mostly use a fixed aging coefficient for compensation, which fails to distinguish the effects of linear aging (such as uniform device decay) and nonlinear aging (such as accelerated oxidation and material fatigue). Especially under complex working conditions (such as high temperature accelerated aging), the measurement accuracy will gradually decrease over time. Summary of the Invention

Moreover, the present application can adopt a computer program product in the form of being implemented on one or more computer usable storage media (including but not limited to disk memory, CD-ROM, optical memory, etc.) containing computer usable program codes.

[0077] In a multi-channel combined power test system, accurate measurement of the power of each single channel is a key link to ensure the performance of the communication system. However, the traditional test method is often significantly affected by environmental and operational factors in practical application, resulting in increased measurement error and affecting the reliability of the test results, including:

[0078] 1. Environmental noise interference: In a non-shielded test environment, external electromagnetic interference (such as radio frequency noise, power supply harmonics, etc.) may be coupled into the measured signal, resulting in a higher power measurement value, especially when high-sensitivity reception or weak signal testing is affected more significantly;

[0079] 2. Device drift caused by temperature and humidity changes: The parameters (such as insertion loss, gain) of devices such as combiners and amplifiers in a multi-channel combined system are easily affected by changes in environmental temperature and humidity, and if not calibrated in real time, it will cause power measurement deviation in long-term testing;

[0080] For the above problems, please refer to Figure 1 The first embodiment of the present application proposes a multi-channel combined power test system, which includes an information acquisition module, a single channel power calculation module, a power correction module and a multi-channel combined power calculation module.

[0081] The information acquisition module is used to acquire first working information and second working information; specifically, the first working information includes the original voltage of each single channel , the detector sensitivity of the detector corresponding to each single channel , and the bias voltage of the detector The second set of operating information includes ambient temperature and ambient humidity. Specifically, the original voltage is obtained by converting the radio frequency power into a DC voltage output value through a detector. It should be noted that the method for obtaining the original voltage is a common existing technology and will not be elaborated here. The detector sensitivity and bias voltage can be obtained from the technical manual provided by the detector manufacturer. Ambient temperature and ambient humidity are obtained by detecting temperature and humidity sensors, respectively. It should be noted that both ambient temperature sensors and humidity sensors are common existing technologies and will not be elaborated here.

[0082] The single-channel power calculation module is used to calculate the first power of each single channel based on the first operating information. Specifically, the first power The specific calculation steps are as follows:

[0092]

[0093] In the formula, Indicates the frequency response compensation of the detector Specifically, frequency response compensation is obtained from the frequency response compensation data sheet provided by the manufacturer, as shown in the following table:

[0094]

[0095] It should be noted that the frequency response compensation value provided by the sound field manufacturer has been calibrated for the reference calibration;

[0096] In step S11 of the present application, the bias voltage of the detector is first removed to obtain a detection voltage, so as to eliminate the expected deviation and ensure that the voltage value calculated subsequently only reflects the actual signal power; in step S12, the detection voltage is converted into linear power, so as to realize the conversion of the voltage signal into a physical power value and provide a basis for subsequent calculation; in step S13, the linear power is converted into logarithmic power in decibel-milliwatt (dBm) units, and it should be noted that decibel-milliwatt (dBm) is a commonly used power unit in the communication field, which is convenient for direct comparison and analysis of signal strength; in step S14, when calculating the first power, the corresponding deviation of the corrected detector at different frequencies is fully considered, so that a frequency response compensation value is introduced to ensure that the power measurement result remains accurate at different frequencies.

[0097] The power correction module is configured to correct the first power according to the second working information to obtain a second power ; Specifically, the environmental temperature, the environmental humidity and the aging degree of the detector will all affect the calculation accuracy of the single-channel power to a certain extent. The common calculation method can consider the influence of each of the above factors on the power alone, but does not consider the mutual influence relationship between these factors. For example, in a high-temperature and high-humidity environment, the metal oxidation of the combiner is accelerated, resulting in an increase in the insertion loss far exceeding the linear superposition of the influence of temperature and humidity alone; high temperature accelerates the aging of the device, such as the drying of the electrolytic capacitor, and the temperature drift coefficient of the aged device becomes larger; long-term high humidity causes the PCB to absorb moisture, and the humidity sensitivity of the aged device is enhanced.
