Abstract
The mechanical phase shifting method is often used to evaluate the accuracy of transmission error (TE) testing system, but the application scope of the mechanical phase shifting method is limited. This paper designed a new type of TE signal generator. Firstly, based on the principle analysis of the mechanical phase shifting method, the relationship between angle error from mechanical phase shifting and pulse signal of sensor is established, and then according to the TE’s synthesis formula we can obtained two displacement sensor signals which are used to replace real mechanical phase forming a special TE signal generator. The signal generator is composed of FPGA and ARM. The TE detection system is used to test the signal generator, after analysis, the error of the TE signal generator is 0.1%, which shows that the TE signal generator can be used to assess accuracy of TE system instead of the mechanical phase shifting method.
