Four front panel LEDs tell you whether the unit is operating in the voltage or current mode, or against the voltage limit or current limit. A mode switch on the front panel selects the operating channel. The tabulation of the effective series resistance and inductance in voltage mode, and the effective shunt resistance and shunt capacitance in current mode, is done to allow a calculation of the output impedance versus frequency.
