Disassembly Procedures
This section discusses the disassembly procedures for troubleshooting and repairing Keysight
N6700C, N6701C, and N6702C MPS mainframes.
Electrostatic Discharge (ESD) Precautions
Almost all electrical components can be damaged by electrostatic discharge (ESD) during handling.
Component damage can occur at electrostatic discharge voltages as low as 50 V.
The following guidelines will help prevent ESD damage during service operations:
l Disassemble instruments only in a static-free work area.
l Use a conductive work area to reduce static charges.
l Use a conductive wrist strap to reduce static charge accumulation.
l Minimize handling.
l Keep replacement parts in original static-free packaging.
l Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
Disassembly Procedures
SHOCK HAZARD. FAN HAZARD. Only qualified, service-trained personnel who are
aware of the hazards involved should remove instrument covers. Disconnect the
power cable and any external circuits before removing instrument covers.
Required Disassembly Tools
l 9/32 Hex driver - for removing GPIB connector
l 5/16 Hex driver - for removing DC cable assembly from bias supply
l T10 Torx driver - for removing covers and board assemblies
l T20 Torx driver - for removing bias/processor board, handles, and bulk supply
Ribbon Cables
l Note the position of the conductive side of the cable for re-installation. (The blue tab is on the non-
conductive side.)
