Load mode operation
The load operating modes for Keysight E36731A battery emulator are:
– Constant current (CC) mode
– Constant voltage (CV) mode
– Constant power (CP) mode
– Constant resistance (CR) mode
When programmed to a mode, the instrument remains in that mode until the mode is changed or until a fault
condition, such as an overpower or over-temperature occurs.
CC mode
In this mode, the load unit will sink a current in accordance with the programmed value regardless of the input
voltage.
The heavy solid vertical line illustrates the locus of possible operating points as a function of the load current. A CC
(constant current) status flag indicates that the load current is at the specified setting. A voltage limit is not
programmable in CC mode. Also, if the DUT imposes a voltage that is above 110% of the rated input voltage, the
overvoltage protection will trip and the load's input will turn off.
Current may be programmed in one of three overlapping ranges, a Low, Medium and a High current range. The low
range provides better programming and measurement resolution at low current settings.
CV mode
In this mode, the load unit will attempt to sink enough current to maintain the input voltage at its programmed
value.
