* 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.
