Abstract

The invention relates to a detection system and method of a voltage-controlled attenuator. The voltage-controlled attenuator is composed of an FPGA, an ARM single chip microcomputer, an AD chip, a DA chip, amplifiers and an attenuator filter, two same detection signals can be sent out, one signal passes through the voltage-controlled attenuator, the other signal does not pass through voltage-controlled attenuator, and a detection result of the quality of the voltage-controlled attenuator is obtained and sent to a PC through final comparison analysis of the two signals. The detection system and method of the voltage-controlled attenuator have the advantages that the structure is simple, operation is easy, the detection cost and the detection difficulty are reduced, the quality of the voltage-controlled attenuator is controlled in incoming inspection, and therefore changing or refunding is conducted in time without affecting later production, research and development.

Description

technical field [0001] The invention relates to a voltage-controlled attenuator, in particular to a detection system and a detection method of the voltage-controlled attenuator. Background technique [0002] The voltage-controlled attenuator is frequently used and expensive. Now, after soldering the PCB, use a network analyzer and a dedicated control circuit to check the quality of the device. When there is a problem with the quality of the voltage-controlled attenuator, it will give R & D and production work Bring huge losses in schedule and cost. Contents of the invention [0003] In order to solve the loss caused by the quality problem of the voltage-controlled attenuator to the research and development and production work, the present invention provides a detection system and detection method of the voltage-controlled attenuator, which can control the quality of the voltage-controlled attenuator in the incoming material inspection link. The specific technology The sch...
