GPIB Programming Interface Examples
// PROGRAM DESCRIPTION:This example program verifies that the GPIB connections and
// and interface are functional.
// Turn signal generator power off then on and then run the program

Local Lockout Using HP Basic and GPIB
This example demonstrates the Local Lockout function. Local Lockout disables the front panel signal
generator keys. basicex2.txt performs the following functions:
• resets instrument
• places signal generator into local
• places signal generator into remote
