tells you that an amplitude offset has been set. An amplitude offset changes the

plus the value for the offset. To eliminate the offset, press
the numeric keypad and press the

Optional Features are Not Working?
If you enable an option that does not have the required hardware installed, the menus for
that option will be activated but the option cannot operate, despite what the menus may
seem to indicate. Check to be sure that the required hardware is physically installed in the
signal generator.
If a software option is disabled but should be enabled, try the following suggestions for
resolution:
• Verify that the optional hardware is installed.
• Verify that the hardware option is enabled.
• Verify that the software option is enabled with the correct license key. Refer to your
License Key Certificate for the correct license key or, if your option was installed by HP,
contact your HP service office with the instrument model number, the host ID, and the
software option that should be enabled.
