DC Output: When a matched load has been specified, MINimum selects -5.12 V;
MAXimum selects 5.11875 V.
Arbitrary Waveform, Ramp, Sine, Square, and Triangle Outputs:
When a matched load has been specified, if the current offset voltage is less than or
equal to 1 V, MINimum selects the equivalent of .16187 V (peak) in the default voltage
units; if the current offset voltage is greater than 1 V, MINimum selects the equivalent of
1.02486 V in the current voltage units. MAXimum selects the equivalent of the lesser of
(+6.025 V - |output offset value|) [rounded down to a value that is a multiple of .01 dB
from 5.11875] and +5.11875 V.
For all waveform shapes, when an open circuit load has been specified, double the 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 all waveform shapes other than DC output, output amplitude control is
implemented as a 0 to 30 dB attenuator with .01 dB resolution. For DC output, the
amplitude is generated using the DAC; resolution is .00125 V into a matched load,
.0025 V into an open circuit.
For DC output, acceptable units are V (volts). For arbitrary waveform output,
acceptable units are V (volts) and VPK. For ramp, sine, square, and triangle
outputs, acceptable units are V (volts), VPK (volts peak), VPP (volts peak-to-peak),
VRMS (volts RMS), W (watts) and DBM or DBMW (dB referenced to 1 milliwatt).
For W, DBM, and DBMW, the amplitude is referenced to the
OUTPut[1]:LOAD
value; they are meaningless and therefore unavailable if OUTPut[1]:LOAD INFinity
is set.
