  The SXFEL (Soft X-ray Free Electron Laser) and DCLS (Dalian Coherence Light Source) have been under con-structions since 2015. To satisfy the huge demands of digital beam position monitor processor, we batch pro-duced over 200 sets of DBPM processor. This paper de-scribes a high automatic test platform based on MATLAB and SCPI, used for the device acceptance test and performance evaluation. The simulation beam sig-nals generated by the Agilent signal source MXG N5181A, connected to a 4-way power splitter. The network control system based on the architecture of the client and server mode, integrated instruments test commands and exper-imental data transferred via a Mercury router. Using EP-ICS LabCA realized the data acquisition channel access interface. The platform has been successfully used for the Dalian Coherent Light Source (DCLS) devices acceptance testing, the noise level, crosstalk between channels, ampli-tude frequency response and SNR test reports automatic generation under test.

A digital BPM processor has been developed in SINAP, which can be used on the signal processing of both stripline BPM and cavity BPM. The processor is a standalone system and providing 4 channels 120MS/s, 16 bits ADC and powerful Virtex-5 FPGA. The processor has been mas applied on Dalian Coherent Light Source and Shanghai X-ray FE. The processor specification and performance evaluations including lab and beam tests will be introduced.
