Keysight Signal Generators Programming Guide
// Declares variables of type ViSession
// for instrument communication
// Declares a variable of type ViStatus
// for GPIB verifications
// Declares variable to hold string data
// Declares variable to hold integer data
// Initialize the VISA system
// Open session to GPIB device at address 19
// If problems, then prompt user
// Resets signal generator
// Querys the CW frequency
// Reads response into rdBuffer
// Prints the source frequency
// Prints new line character to the display
// Querys the power level
// Reads the response into rdBuffer
// Prints the source power level
// Prints new line character to the display
