    NAME
           psout - Export PIB Prescalers

    SYNOPSIS
           psout [options] file [>stdout]

    DESCRIPTION
           Export the prescaler section of a PIB file as an amplitude map suitable for input to program psin or the Qualcomm Atheros
           Windows Device Manager.  Prescalers are stored in the PIB in binary format but the amplitude map is  in  text  format  so
           that  values  may be changed using an ordinary text editor.  Program psin can be used to import an amplitude map into the
           original or another PIB file.

           This program is part of the Qualcomm Atheros Powerline Toolkit.  See the AMP man page for an  overview  and  installation
           instructions.

    OPTIONS
           None.

    ARGUMENTS
           file   The  name  of  an  Atheros Parameter Information Block (PIB) file.  This file is not modified.  By convention, PIB
                  files have a .pib extension but this program does not enforce that convention and does  not  make  any  assumption
                  based  on  filename or extension but the program will reject invalid PIB files.  Only one filename is permitted on
                  the command line.

    FILES
           An amplitude map consists of 1155 frequency-amplitude pairs.  Each pair consists of a decimal  index  and  a  hexadecimal
           scaler.   The  index  represents a frequecy from 1.8 mhz through 30 mhz.  The scaler represents the amplitude attenuation
           applied at that frequency.  The frequency and attenuation are computed as follows.

                frequency = 40.96 * (index + 74)

                index = (frequency / 40.96) - 74

                decibels = 20 * log10 (scaler / 256)

                scaler = 256 * pow (decibels / 20)

    EXAMPLES
           The following example prints the prescaler section of file abc.pib on stdout as an amplitude map.  The  output  has  been
           abbreviated here to save space.  A single comment line identifies the prescaler source file.  Output may be directed to a
           text file, edited using a text editor and read into the same or another PIB file with program psin.

              # psout abc.pib
              # file: abc.pib
              00000000 00000000
              00000001 00000000
              00000002 00000000
              00000003 00000000
              ...
              00000027 000000D0
              00000028 000000D0
              00000029 000000D1
              00000030 000000D1
              ...
              00000214 00000000
              00000215 00000000
              00000216 00000000
              ...
              00001155 00000000

           The next example copies prescalers from file abc.pib to def.pib using a command line pipe.

              # psout abc.pib | psin def.pib
