Total System of 324MHz-Low Level RF Control for J-PARC Linac was produced and its performance study was done. In this system, in order to stabilize the Klystron output and to compensate the linearity of that, an analog feedback control system is adopted. The response function including phase characteristic (vector locus) of this feedback system was obtained by means of measurement. From this result the prospect for the transient analysis is discussed.
