Addendum A - SERVICE MANUAL

Agilent Technologies Model E4350B and E4351B Solar Array Simulators - P/N 5962-8233 For units with serial numbers:

E4350B US37410101 and up

E4351B US37430101 and up

This addendum contains information for troubleshooting and repairing the Agilent E4350B and E4351B Solar Array Simulators. The standard Service Manual for the Agilent Series 665xA DC Power Supplies (P/N 5959-3376), together with this Service Addendum, is shipped with the Solar Array Simulators when ordered with Option 910.

Note This addendum is to be used along with the standard Service Manual for the Agilent Series 665xA DC Power Supplies. When troubleshooting the Agilent E4350B/E4351B Solar Array Simulators, start by following the procedures outlined in the standard Service Manual. This addendum documents only the differences between the standard troubleshooting procedures and the troubleshooting procedures for a Solar Array Simulator.

Areas of Difference

From a service point of view, the main difference between the SAS unit and the Agilent Series 665xA dc power supply is the addition of a Digital Signal Processor (DSP) board located over the main A1 board. This DSP board includes the portions of CV, CC, OV, and OC control circuits such as the programming DAC circuits, as well as a microprocessor and programmable gate array that is used to generate the output I-V curve. The output I-V curve simulates the output characteristics of a solar array.
