We report on the timing and spectral analysis of two Suzaku observations with different flux levels of the high-mass X-ray binary KS 1947+300 during its 2013 outburst .
In agreement with simultaneous NuSTAR observations , the continuum is well described by an absorbed power law with a cut-off and an additional black body component .
In addition we find fluorescent emission from neutral , He-like , and even H-like iron .
We determine a pulse period of \sim 18.8 s with the source showing a spin-up between the two observations .
Both Suzaku observations show a very similar behavior of the pulse profile , which is strongly energy dependent , with an evolution from a profile with one peak at low energies to a profile with two peaks of different widths towards higher energies seen in both , the Suzaku and NuSTAR data .
Such an evolution to a more complex profile at higher energies is rarely seen in X-ray pulsars , most cases show the opposite behavior .
Pulse phase-resolved spectral analysis shows a variation in the absorbing column density , N _ { \mathrm { H } } , over pulse phase .
Spectra taken during the pulse profile minima are intrinsically softer compared to the pulse phase-averaged spectrum .
