// Declares a variable of type ViStatus
// for GPIB verifications
// open session to gpib device at address 19
// If problems, then prompt user
// Clears the signal generator
// Resets the signal generator
// Sets FM path 2 modulation deviation rate of 100 kHz
// Sets carrier frequency to 900 MHz
// Sets the power level to -15 dBm
// Turns on frequency modulation
// Turns on RF output
// Prints a carriage return
// Print user information
// Print a carrage return
