The init_IO routine initializes the analyzer and interface so that the scope can capture data
and perform measurements on the data. At the start of the program, global symbols are
defined which will be used to store and convert the digitized data to time and voltage values.
init.c - Initializing the Analyzer
/*
* Function name: initialize
* Parameters: none
* Return value: none
* Description: This routine initializes the analyzer for proper
* acquisition of data. The instrument is reset to a known state and the
* interface is cleared. System headers are turned off to allow faster
* throughput and immediate access to the data values requested by queries.
* The analyzer time base, channel, and trigger subsystems are then
* configured. Finally, the acquisition subsystem is initialized.
