Troubleshooting the Power Supply
Introduction
Introduction
This chapter helps verify that the power supply is at fault when no indication for power is
present upon power-up. If the power supply appears defective, the problem can be
localized to the line module, mains (line) fuse, transformer, power supply, regulator,
motherboard, or power switch. This chapter is arranged to check each section of the power
supply. The views of the instrument in this chapter are both top and bottom views with the
covers removed. Refer to chapter 8 “Assembly/Disassembly” for help in removing the
covers.
NOTE The mains (line) fuses and power supply DC fuses in the HP/Agilent 8922 are all fast-blow
fuses (not “slow-blow”).
