Output Configuration

Voltage Autoranging

Autoranging is enabled by default and the function generator
automatically selects the optimal settings for the output amplifier and
attenuators. With autoranging disabled, the function generator uses the
current amplifier and attenuator settings.
• You can disable autoranging to eliminate momentary disruptions
caused by switching of the attenuators while changing amplitude.
However, turning autoranging off has side effects:
• The amplitude and offset accuracy and resolution (as well as
waveform fidelity) may be adversely affected when reducing the
amplitude below a range change that would occur with
autoranging on.
• You may not be able to achieve the minimum amplitude that is
available with autoranging on.
• Front-Panel Operation: Press
softkey. Then press the Range softkey again to toggle between the
"Auto" and "Hold" selections.
• Remote Interface Operation:
VOLTage:RANGe:AUTO {OFF|ON|ONCE}
The APPLy command overrides the voltage autorange setting and
automatically enables autoranging.

Output Control

You can disable or enable the front-panel Output connector. By default,
the output is disabled at power on to protect other equipment. When
enabled, the key is illuminated.
• If an excessive external voltage is applied to the front-panel Output
connector, an error message will be displayed and the output will
be disabled. To re-enable the output, remove the overload from the
Output connector and press
• Front-Panel Operation: Press
66
and select the Output Setup
to enable the output.
to enable or disable the output.
