    Generates  and draws a spectrum with only gaussian noise of rms S, to be
    compared with actual receiver noise.

    S defaults to the rms computed in the BASE section of the current  spec-
    trum.  If  this  section is absent, it is computed from Tsys, resolution
    and integration time in the GENERAL section. If one of these  values  is
    null  (e.g.  spectrum  was  generated by the command MODEL), an error is

    If the argument NEW is present, the spectrum is not plotted  but  the  R
    buffer is copied in T, and the generated noise put into the R buffer.
