// PROGRAM DESCRIPTION:This example sets the signal generator FM source to External 2,
// coupling to AC, deviation to 20 kHZ, carrier frequency to 700 MHz and the power level
// to -2.5 dBm. The RF state is set to on.

// Declares a variable of type ViStatus
// for GPIB verifications
// Initialize VISA session
// open session to gpib device at address 19
// If problems, then prompt user
// Resets the signal generator
// Sets EXT 2 source for FM
// Sets FM path 2 coupling to AC
// Sets FM path 2 deviation to 20 kHz
// Sets carrier frequency to 700 MHz
