Single Quadrant Operation
The Keysight N6700 Modular Power System can operate in either
constant voltage (CV) or constant current (CC) over the rated output
voltage and current. Constant voltage mode is defined as an operating
mode in which the dc source maintains its output voltage at the
programmed voltage setting in spite of changes in load, line, or
temperature. Thus, when the load resistance changes, the output
voltage remains constant while the output current changes to
accommodate the change in load.
Constant current mode is defined as an operating mode in which the dc
source maintains its output current at the programmed current limit in
spite of changes in load, line, or temperature. Thus, when the load
resistance changes, the output current remains constant while the
output voltage changes to accommodate the change in load.
All DC power modules, except for Keysight Models N678xA SMU,
are designed as constant voltage sources. This means that the
specifications and operating characteristics are optimized for constant
voltage mode operation. Note that these power modules cannot be
programmed to operate in a specific mode. At turn-on, the operating
mode will be determined by the voltage setting, current setting,
and
the
load resistance. In the following figure, operating point 1 is defined by a
fixed load line traversing the positive operating quadrant in the constant
voltage region. Operating point 2 is defined by a fixed load line
traversing the positive operating quadrant in the constant current
region.
