  The Japan Proton Accelerator Research Complex (J-PARC) linac beam pulse, generated by a beam chopper system placed at the MEBT, comprises a series of intermediate pulses with a comb-like structure synchronized with the radio-frequency of the rapid cycling synchrotron (RCS). The sequentially measuring and monitoring the comb-like beam pulse ensures the beam stability with less beam loss at the current operation and higher beam intensity scenarios at the J-PARC. However, signal processing as a function of the pulse structure is challenging using a general-purpose digitizer, and monitoring the entire macro pulse during the beam operation is unavailable. To this end, an advanced beam monitor digitizer complying with the MicroTCA.4 (MicroTelecommunications Computing Architecture.4) standard, including digital signal processing functions, has been developed. This paper reports the implementation, performance evaluation, and the first results of this unique beam monitor digitizer.
