vdif2m5b

DESCRIPTION

"vdif2m5b" converts VDIF format data to Mark5B format data.

SYNOPSIS

vdif2m5b vdif_file [options]
   or
k5tom5b --version|--help

 where

vdif_file VDIF data file to be converted
--version show program version
--help show how to execute
OPTIONS
-o m5bfile set Mark5B file name to be created
-d m5dir set directory for Mark5B file out (default: VDIF directory)
-fsampl fmhz channel sampling frequency (MHz) to compulsory set
-2bit mode set 2bit AD decode table
1:offset binary 0,1,2,3 (no conversion)
2: Mark V standard 0,2,1,3 (default)
3: signed integer 1,0,2,3
-s soffset set offset time from data head (sec) (default: 0.0)
-p period set data period to convert (sec) (default: all)
-type1 set output file naming Type 1 (replace file extention by "m5b") (default is Type 0)
-pid thread_id set pickup thread ID compulsory
-ch1 nn set VDIF channel # corresponding to Mark5 ch #1
nn is VDIF channel number (1-16)
-ch2 nn set VDIF channel # corresponding to Mark5 ch #2
.......................
-ch16 nn set VDIF channel # corresponding to Mark5 ch #16
-chall n1:n2:....:nNN
set VDIF channels corresponding to Mark5 all channels
n1 -- VDIF channel number (1-16) corresponding to Mark5 ch #1
n2 -- VDIF channel number (1-16) corresponding to Mark5 ch #2
....................
nNN -- maximum is 16 channel

Naming rule for Mark5B file created (VDIF.vdif : original VDIF name)
     Type 0 -- VDIF.vdif.m5b (default)
     Type 1 -- VDIF.m5b

EXAMPLES

Example 1

use default settings.
