  • Page 28: Load Operating Modes

    Load Operating Modes The load operating modes for Keysight EL30000 Series DC electronic load are: – Constant current (CC) mode – Constant voltage (CV) mode – Constant power (CP) mode – Constant resistance (CR) mode When programmed to a mode, the electronic load remains in that mode until the mode is changed or until a fault condition, such as an overpower or over-temperature occurs.

  • Page 29: Cv Mode

    Voltage may be programmed in one of two overlapping ranges, a Low and a High range. The low range provides better programming and measurement resolution at low voltage settings. CP mode In this mode, the load unit will regulate the power being drawn from the DUT according to the programmed constant-power value. Keysight EL30000 Series User's Guide...
