pitch beep confirms an entry, and a longer lower pitch beep signals

is helpful for testing and debugging system application software.
When enabled, half of the screen is used to display commands
performed by the 1258. Each command is proceeded by a
designator of its source: E (Ethernet), G (GPIB), M (Manual), or R
(RS232). Manual refers to commands performed through the
front-panel. All communication commands display the string
received on the first line, and the command recognized by the
1258 on the next line. See Configuration Commands and Queries
for details on executing this command remotely. The Error Log in
the SYSTEM
Ö
ERROR LOG menu, which provides a list of the last
ten errors that have occurred, can also be very useful when
debugging application software.
