Abstract: We conducted a study of PSR J1224−6407 at three frequency bands using the Parkes radio telescope in Australia, with a time span of about 10 years. The central frequencies of the three bands are 732 MHz, 1369 MHz, and 3100 MHz, respectively. By combining the measured flux densities with spectral data from literature, we derived the spectral characteristics of the pulsar. A simple power-law spectrum model was used to fit the spectrum, resulting in a spectral index of −1.45. The average pulse profiles and polarization observations at the three frequencies were obtained using the PSRCHIVE software. The total intensity, circular polarization, linear polarization, and polarization position angle curves exhibited different variations with frequency. At the frequency of 1.4 GHz, we analyzed the timing residuals of the pulsar and updated its basic parameters such as position, rotation period, and period derivative.
