The X-ray beam position monitor (XBPM) can be used to measure the position of beamline synchrotron radiation light. The front-end acquisition circuit of XBPM is mainly used for analog signal acquisition and processing. To meet the demand for precise measurement of synchrotron light position information in the beamline front-end area of high energy photo source (HEPS), an XBPM electronic analog front end (AFE) board card has been developed in this paper. The functions such as current-voltage conversion, range switching, gain control and ADC sampling of XBPM signals were designed and implemented, and a laboratory test platform was built to conduct performance tests on XBPM-AFE. The test results show that the current input range of the I/V conversion module is from 10 nA to 1 mA. When the input current varies by three orders of magnitude, the linear error of the transimmer gain in each range segment remains at a relatively low level. The average relative standard deviation of the measurement results among the four channels is less than 0.46%. The analog-to-digital conversion module can accurately reflect the signal input conditions with changing speeds of over 0.1 s and 1 ms respectively in both slow acquisition and fast acquisition modes.
