DC Output: When a matched load has been specified, MINimum selects -5.12
V; MAXimum selects 5.11750 V.
Arbitrary Waveform, Ramp, Sine, Square, and Triangle Outputs:
MINimum will select the equivalent of 0 V in the current default units. MAXimum
selects the equivalent of the lesser of (+6.0 V - output offset value) and
+5.11750 V.
For all waveform shapes, when an open circuit load has been specified, double
all the above voltages.
These values bound the legal range of values for amplitude .
Default units are specified by the
SOURce:VOLTage:LEVel:IMMediate:AMPLitude:UNIT:VOLTage command.
For DC output, the amplitude is generated using the DAC; resolution is
.0025 V into a matched load, .005 V into an open circuit. For all other
waveform shapes, output amplitude control is implemented via a output
multiplier circuit, followed by a switchable 20 dB step attenuator. The step
attenuator is used only when both amplitude and offset are each below one
tenth of their full scale values.
For DC output, acceptable units are
output, acceptable units are
triangle outputs, acceptable units are

An amplitude of -9.9e37 DBM or DBMW is equivalent to 0 V.
