    Installation 2 Power Module Installation The information in this section applies if you have purchased an N6705 NOTE mainframe without the power modules installed, or if you are adding a power module to the mainframe. Turn the mainframe off and disconnect the power cord before installing or CAUTION removing power modules.
  • Page 30 Observe the output color code. Tighten all connector screws. An adapter “A” is required to install modules in Agilent N6705A mainframes. For model N6781A, install the auxiliary measurement (Aux Meas) cable.

  • Page 31: High Current Output Connections

    High current (50 A) load connections are made using the rear panel access ports of the Agilent N6705B. These access ports have a thin rubber membrane which can be pierced using the load wires.

  • Page 32: Bench Installation

    Use Rack Mount kit (Option 908 or Option 909 with handles) to rack mount the CAUTION instrument. Installation instructions are provided with the rack mount kit. Agilent N6705 DC Power Analyzer mainframes can be mounted in a 19-inch EIA rack cabinet. They are designed to fit in four rack-units (4U) of space.

  • Page 33: Connecting The Line Cord

    Connect the power cord to the IEC 320 connector on the rear of the unit. If the wrong power cord was shipped with your unit, contact your nearest Agilent Sales and Support Office. The AC input on the back of your unit is a universal AC input. It accepts nominal line voltages in the range of 100 VAC to 240 VAC.

  • Page 34: Wire Size And Length

    (refer to the table below). To satisfy safety requirements, load wires must be heavy enough not to overheat while carrying the short- circuit output current of the unit. Agilent Model N678xA SMU wiring requirements are described on the following page.

  • Page 35: Agilent N678Xa Smu Wiring Requirements

    Because of the effect of wire inductance, the wire length information given in NOTE the previous table does not apply to Agilent Models N678xA SMU. To minimize the effect of wire inductance, the following table describes the allowable load lead and wire length for several common cable types.
  • Page 36 As shown below, cable guards are available at the internal connector of Agilent 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 37: Multiple Loads

    Keep the load leads under 14.7 meters (50 feet) per lead because of inductance effects. Agilent Models N678xA SMU have additional wiring restrictions as discussed under “Agilent N678xA SMU Wiring Requirements”. If load considerations require the use of distribution terminals that...
  • Page 38 0.5Ω per lead (this requires 20 AWG or heavier for a 50 foot length). Agilent Models N678xA SMU require remote sensing when using any of the High output bandwidth modes discussed in Chapter 6. Also, these models have additional wiring restrictions as discussed under “Agilent N678xA SMU Wiring Requirements”.
  • Page 39 OVP circuit could be higher than the voltage being regulated at the load. Note that for Agilent Models N678xA SMU only, the OVP circuit senses at the 4-wire sense terminals rather than at the output terminals.

  • Page 40: Parallel Connections

    Parallel Connections Only connect outputs that have identical voltage and current ratings in parallel. CAUTION Agilent Models N678xA SMU cannot be connected in parallel. Connecting outputs in parallel provides a greater current capability than can be obtained from a single output.

  • Page 41: Series Connections

    Only connect outputs that have identical voltage and current ratings in series. CAUTION Agilent Models N678xA SMU and N6783A–x cannot be connected in series. To prevent reverse currents from damaging the DC Power Analyzer when the load is connected, always turn series-connected outputs on and off together.

  • Page 42: Additional Load Considerations

    Respo (Current Limit Setting)−(Load Current) Note that programming into an external output capacitor may cause the DC Power Analyzer to briefly enter constant current or constant power operating mode, which adds additional time to the estimation. Model N6705 User’s Guide...
  • Page 43 The instrument can be operated with any output terminal ± 240 VDC including output voltage from ground. Agilent Models N678xA SMU are optimized for grounding the negative output NOTE terminal. Grounding the positive terminal may result in increased current measurement noise and a reduction in current measurement accuracy.
