    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.
