Problems solved by technology
At this time, it is necessary to manually move the probe from the measured end to the output end of the calibration source for calibration, and then re-establish the calibration table for temperature compensation. It takes about 2 minutes. The whole process is time-consuming and laborious, which seriously affects the efficiency and consistency of the measurement. sex
[0004] Since the calibration cannot be performed in real time, the above calibration scheme cannot be satisfied for systems and equipment with frequent temperature fluctuations and high requirements for real-time measurement accuracy.

The invention discloses a temperature compensation system and method of peak power probes. According to the system, a plurality of compensation probes are arranged in a high and low-temperature test chamber; the input end of a power divider is connected with a signal source; one output end of the power divider is controlled with the peak power probes requiring compensation in the high and low-temperature test chamber through a program-control multi-way switch; the other output end of the power divider is connected with a standard power meter; a compensation power meter is connected with the plurality of compensation probes through a multi-core cable respectively; and a computer communicates with the compensation power meter through a GPIB. The temperature compensation system and method ofthe invention have the advantages of high measurement efficiency and short temperature compensation time. According to the temperature compensation system and method of the invention, measurement is automatically completed through the DSP of a host computer, and human intervention is not required; and the compensation time of the system and method is about 10ms.
Description
technical field [0001] The invention relates to the technical field of temperature compensation of a peak power sensor, in particular to a temperature compensation system and method for a peak power sensor. Background technique [0002] Since the detection circuit of the peak probe and the logarithmic amplifier after detection are temperature-sensitive devices, the ADC (Analog to Digital Converter) value measured at different temperatures with the same input power deviates greatly. In order to solve this kind of deviation, it is necessary to carry on the temperature compensation to the probe. [0003] Since most current peak power sensors do not have temperature compensation, their temperature characteristics are guaranteed by an external calibration source, that is, the external calibration source is temperature compensated, so as long as the temperature changes by more than 5°C, the host will prompt the user to Connect the probe to the calibration source for recalibration...
