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
The following program example is available on the signal generator Documentation CD- ROM as
basicex2.txt.

The LOCAL command, executed from the controller, is then
the only way to return the signal generator to front panel,
