Spectroscopic scans were made of two cataclysmic variables (CVs) containing dwarf stars in order to define a model for the observed burst phenomena. CVs have been classified into three groups according to their outburst periods: quick rises and falls, sustained peaks, and the presence of regular and superoutbursts. The present campaign covered the objects CPD-48 deg 1577 and HL CMa. Orbital period, spectral features, continuum distributions, and IR data are discussed. The two CVs had similar line features, line profile structures, and continuum shapes; however, no quiescent stage was observed for CPD-48 deg 1577, which also exhibited evidence for a magnetic field, an uncommon dwarf feature.
