Autoranging
NOTE
Autoranging only applies to Agilent N675xA and N676xA power modules.
The following figure illustrates the autoranging output characteristic
of the Agilent N675xA and N676xA power modules. Point 3 shows a
situation in which the voltage and current settings are such that the
operating locus is limited by the maximum output power boundary of
the output. Depending on the power module, this may be greater than
the output power rating of the module. In this situation, the output is
not guaranteed to meet its operating specifications because it is
operating in an area that is outside its specified power rating.
Downprogramming
As shown by the dashed line on the left in the figures, the power
system is capable of sinking current over the output voltage range
from zero volts to the rated voltage. This negative current sinking
capability provides fast downprogramming of the output. The
negative current is not programmable.
