learnstr.c Sample Program
/* learnstr.c */
/*
* This example program initializes the Agilent 86100 scope, runs autoscale to
* acquire a signal, queries for the learnstring, and stores the learnstring
* to disk. It then allows the user to change the setup, then restores the
* original learnstring. It assumes that a signal is attached to the scope.
