AMPTD Y Scale
Range Auto/Man
The Auto setting for Range causes the range to be set based on the Y Scale settings. When Range is
"Auto", the I & Q Range are set based on the top of the Y Scale when the Y scale is in dB units (for
example, power), or to the max(abs(top), abs(bottom)) when the Y scale reference is not at the top of the
screen.
Not all measurements support Range Auto/Man. If Auto is not supported in the current measurement,
this key is grayed out and shows "Man" and MAN is returned to a SCPI query; but this does NOT
change the Auto/Man setting for Range.When you go to a measurement that supports Auto, it goes back
to Auto if it was previously in Auto mode.

[:SENSe]:VOLTage:IQ:RANGe:AUTO OFF|ON|0|1
[:SENSe]:VOLTage:IQ:RANGe:AUTO?
Put the I Range and Q Range in manual.
VOLT:IQ:RANG:AUTO OFF
If Auto is not supported, sending the SCPI command will generate an error.
When in Auto, both I Range and Q Range are set to the same value, computed
as follows:
Maximum absolute value is computed for the Y Scale. The top and bottom of
the graph are computed based on Ref Value, Scale/Div, and Ref Position.
Formula: YMax = max(abs(top), abs(bottom)).
The I Range and Q Range are then set to YMax.

[:SENSe]:POWer:IQ:RANGe:AUTO OFF|ON|0|1
[:SENSe]:POWer:IQ:RANGe:AUTO?
Put the I Range and Q Range in manual.
POW:IQ:RANG:AUTO OFF
The POW:IQ:RANG:AUTO is an alternate form of the
VOLT:IQ:RANG:AUTO command. This is to maintain consistency with I
Range and Q Range, which support both the POWer and VOLTage forms of
the command.
