Keysight Technologies 33210A - Voltage Autoranging; Output Control

Features and Functions 3
Keysight 33210A User’s Guide 79
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 and select the Output Setup 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 to enable the output.
– Front-Panel Operation: Press to enable or disable the output.
