VOLTage:RANGe:AUTO?
Disable or enable voltage autoranging for all functions. In the default mode,
autoranging is enabled ("ON") and the function generator automatically selects
the optimal settings for the output amplifier and attenuators. With autoranging
disabled ("OFF"), the function generator uses the current amplifier and attenuator
settings. The :AUTO? query returns "0" (OFF) or "1" (ON).
– The APPLy command overrides the voltage autorange setting and
– The advantage of disabling autoranging is to eliminate momentary disruptions
– The "ONCE" parameter has the same effect as turning autoranging "ON", and

and the low level to -3 volts, the resulting amplitude is 5 Vpp (with an offset
voltage of -500 mV).
setting, the displayed voltage levels will be automatically adjusted (and no
error will be generated). For example, if you set the high level to +100 mVdc
and then change the output termination from 50 ohms to "high impedance",
the voltage displayed on the function generator's front-panel will double to
+200 mVdc. If you change from "high impedance" to 50 ohms, the displayed
voltage will drop in half. See the OUTP:LOAD command on page 199 for
more information.

the amplitude and offset accuracy and resolution (as well as waveform fidelity)
may be adversely affected when reducing the amplitude below the expected
range change.
