The integrated pulse profiles of 27 pulsars are measured at 4.6 and 10.7 GHz in an effort to determine their integrated flux valuues. The validity of current dispersion measure determinations which rely solely on integrated pulse profiles is assessed, and experimental results are outlined and subsequently interpreted in the framework of a two-component magnetic field model. Nondispersive time shifts were exhibited by the following PSRs: (1) 0809 + 74, (2) 0031 - 07, (3) 1642 -03, and (4) 2020 + 28. Data show that at high frequencies, pulse-width narrowing abates and pulse energy spectra steepen. Interpretation of experimental results in the framework of a two-component magnetic field model suggests that dipole fields dominate at large distances from the neutron star, whereas magnetic-field quadripole components dominate at small distances.
