WARNING
These troubleshooting instructions are for use by qualified personal only. To avoid
electrical shock, do not perform any troubleshooting unless qualified.
WARNING
The opening of covers or removal of parts is likely to expose dangerous voltages.
Disconnect the signal generator from all voltage sources before it is opened.
The following techniques related to ESD and static-safe workstations should not be

used when working on circuitry with a voltage potential greater than 500 volts.
ESD Information
Protection from Electrostatic Discharge
Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic assemblies
should be performed at a static-safe workstation using two types of static-safe workstation protection:
• conductive table-mat and wrist-strap combination
• conductive floor-mat and heel-strap combination
Both types, when used together, provide a significant level of ESD protection. Of the two, only the table-mat
and wrist-strap combination provides adequate ESD protection when used alone. To ensure user safety, the
static-safe accessories must provide at least 1 meg ohm of isolation from ground.
Handling of Electronic Components and ESD
CAUTION
Many of the assemblies in this instrument are very susceptible to damage from electrostatic
discharge (ESD). Perform troubleshooting procedures only at a static-safe workstation and
wear a grounding strap.
CAUTION
Always handle printed circuit board assemblies by the edges. This will reduce the possibility of
ESD damage to components and prevent contamination of exposed plating.
The possibility of unseen damage caused by ESD is present whenever components are transported, stored, or
used. The risk of ESD damage can be greatly reduced by close attention to how all components are handled.
• Perform work on all components at a static-safe workstation.
• Keep static-generating materials at least one meter away from all components.
• Store or transport components is static-shielding containers.
