Syntax
POWer:REFLevel:ABSolute:LOW <NR3>; Ranges={D,-1e6, +1E6}
POWer:REFLevel:ABSolute:LOW?
Arguments
<NR3> is a floating point numb
er that specifies the absolute low value in volts.
Default value is 0.0E+0.
Examples
POWER:REFLEVEL:ABSOLUTE:LOW 1.0 sets the absolute high value to 1.0000.
POWER:REFLEVEL:ABSOLUTE:LOW? might return
