   PSR B0833-45 (Vela pulsar) is a proto-type of rotation-powered pulsar
   together with the Crab pulsar. Our understanding of the pulsars is
   basically based on these two pulsars. PSR B0833-45 is very luminous in
   Gamma-rays, but X-ray pulsation was detected only very recently by
   ROSAT. We estimated ASCA detection limit of pulsed X-ray flux from
   PSR0833-45 based on the outer gap model and pulsed black body component
   detected by ROSAT PSPC. We found that ASCA SIS can detect the pulsed
   black body with good statistics. Detection of outer gap emission by GIS
   may be marginal. Studies of the pulsation from PSR B0833-45 in higher
   energy band with ASCA will play an important role in improving our
   knowledge of the emission mechanism of the pulsars.
