g_speana

DESCRIPTION

"g_speana" displays spectrum of data supporting a variety of data formats (Mark5B, VDIF, ADS, OCTAD, VSSP).

SYNOPSIS

g_speana filename [mode [sekibun [pmode [comment [soffset [f1khz [f2khz [mindbm [maxdbm]]]]]]]]]
   or
g_speana filename [options]
   or
g_speana --version|--help

 where

filename data file name (supporting data formats are ark5B, VDIF, ADS, OCTAD, VSSP)
mode set axis mode or autocorrelation mode
0 : amplitude log, frequency log
1 : amplitude log, frequency linear (dfault)
10 : amplitude linear, frequency log
11 : amplitude linear, frequency linear
-1 : plot auto correlation function
-N : plot auto correlation function (central N points)
sekibun integration period (sec) (default 1.0)
pmode plot device selection
0 : "/XSERVE" and PostScript file (pgplot.ps) out (dfault)
1 : PostScript file (pgplot.ps) out only
2 : "/XSERVE" only
comment comments appeared in graphics
soffset start time offset (sec) (default 0.0)
f1khz search frequency range (lower boundary) (kHz) for power Maximum (default is 0.0)
f2khz search frequency range (upper boundary) (kHz) for power Maximum (default is video frequency)
mindbm display amplitude minimum (dBm) (default auto)
maxdbm display amplitude maximum (dBm) (default auto)
--version show program version
--help show how to execute
