  • Page 51: Inspect The Unit

    Inspect the Unit When you receive your power system, inspect it for any obvious damage that may have occurred during shipment. If there is damage, notify the shipping carrier and nearest Keysight Sales and Support Office immediately. Until you have turned on and checked out the power system, save the shipping carton and packing materials in case the unit has to be returned.

  • Page 54: Rack Mounting

    The Rack Mount Kit is also available by ordering part number N6709A. Keysight N6700 MPS mainframes can be mounted in a 19-inch EIA rack cabinet. They are designed to fit in one rack-unit (1U) of space. Do not block the air intake and exhaust at the sides of the unit, or the exhaust at the rear of the unit.

    Load Capacitor Response Times Ferrite Core Installation - for Keysight N6792A only Protecting Sensitive Loads Keysight N679xA Load Module input terminals are referred to as "Outputs" throughout this document Output Wiring SHOCK HAZARD Turn off AC power before making rear panel connections. All wires and straps must be properly connected with the terminal block screws securely tightened.

  • Page 58: Wire Sizing

    (refer to the following table). To satisfy safety requirements, load wires must be heavy enough not to overheat while carrying the short-circuit output current of the unit. Keysight Model N678xA SMU wiring requirements are described in the following section.
  • Page 59 4. “x” indicates wire is not rated for the maximum output current of the power module. 5. Because of wire inductance considerations, it is also recommended that you keep your load leads twisted, tie wrapped, or bundled together and less than 50 feet (14.7 meters) in length per lead. Keysight N6700C Operating and Service Guide...

  • Page 60: Keysight N678Xa Smu Wiring

    2 to 10 meters (inductance per cable foot ≤ 32 nH) High Bandwidth Modes with Remote Sensing The following wiring requirements apply when using Keysight Models N678xA SMU in the High bandwidth modes with remote sensing. Refer to Output Bandwidth for more information about the bandwidth settings.
  • Page 61 1 μA and greater. As shown below, cable guards are available at the output connector of Keysight Models N678xA SMU. The guard is typically used to drive the shields of cables and test fixtures. It provides a buffered voltage that is at the same potential as the + output terminals of the module connector.

  • Page 62: Multiple Load Wiring

    The goal is to always minimize the loop area or physical space between the + and - load wires from the power system to the load. Note that Keysight Models N678xA SMU have additional wiring restrictions as previously discussed under Keysight N678xA SMU Wiring.

  • Page 165: Mainframe Power Allocation

    Power Limit Allocation Mainframe Power Ratings For the majority of Keysight N6700C MPS configurations, full power is available from all installed power modules. However, it is possible to configure a power system in which the combined ratings of the power modules exceed the power rating of the mainframe. The power system will continue to operate normally as long as the combined module output power is within the power rating of the mainframe.

  • Page 166: Power Limit Allocation

    For Keysight N675xA, and N676xA power modules, the power limit function will limit the output power at its programmed setting. A status bit (CP+) will indicate that the output is in power limit mode. When the power drawn by the load is reduced below the power limit setting, the output automatically returns to normal operation - either constant voltage or constant current mode.

  • Page 167: Operating Mode Tutorial

    Keysight N679xA Load Module Operation Single-Quadrant Operation The Keysight N6700C 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.

  • Page 168: Multi-Quadrant Operation

    Keysight Models N678xA SMU can be operated in either voltage or current priority mode. They can source as well as sink output power. Note that Keysight Models N6781A, N6782A, N6785A, and N6786A operate only in the + Voltage quadrants. Voltage Priority Mode In voltage priority mode, the output voltage should be programmed to the desired positive or negative value.

    OC and PROT status bits will be set. Keysight N679xA Load Module Operation The operating modes of operation for Keysight N6791xA Load modules are: current priority, voltage priority, power priority, and resistance priority. When programmed to a mode, a module remains in that mode until the mode is changed or until a fault condition, such as an over=power or over-temperature occurs.
  • Page 172 In this mode, the load module will regulate the power being drawn from the DUT according to the programmed constant power value. The load module regulates the input power by measuring the input voltage and current and adjusting the input power based on data streamed from the measurement ADCs. Keysight N6700C Operating and Service Guide...
  • Page 173 The load module automatically selects the resistance range that best corresponds to the resistance value that you program.
