Abstract:This paper designs a set of automatic metering system suitable for general-purpose signal generators, the system is coded through the software platform, and the hardware is connected as a control bus to achieve automatic measurement calibration of the main types of signal generators, so as to reduce labor costs, improve work efficiency and accuracy. Its good compatibility and practicality make the system have a good promotion and application value. The automatic metering system has been widely used in the automatic verification of signal generators in factories.
