Generate a constantly updating strip chart of the Band limited RMS of a set of bands defined by a configuration file. Each channel displays the power produced on a single channel in a limited band width. By default, the scale is logarithmic with a factor of 10 corresponding to half the pen spacing. The Channel configuration for the strip chart is specified by an ascii file passed as an argument to Chart. The format of the file is as follows:

   Line 1: <nPens> <tAccum> <write> <nSteps>
   Line 2: <Title>
   Line 3: <output>
   ...   : <channel> <fLow> <fHigh>

   

The fields on the first 3 lines have the following meaning:

   <nPens>     The number of pens to be displayed.
   <tAccum>    The accumulation period in seconds. Data from each
               specified channel will be accumulated for the period 
               specified by <tAccum>
   <write>     Specifies whether data are to be written to a log file.
               <write=0 indicates that no log file is to be written.
   <nSteps>    The number of time intervals to be displayed on the strip 
               chart.
   <Title>     A title for the chart. The title is displayed on the 
               strip chart window.
   <output>    a fully qualified file name for the strip chart log.
   

Following these lines comes a description of the contents of each pen. One line must be specified for each pen containing:

   <channel>      The name of the channel from which the data are derived.
   <fLow>         the minimum fraquency.
   <fHigh>        The maximum frequency.
   

Parameters:

Config - Name of a configuration file defining the char parameters.
