Step 2. Set up Static-Safe Workstation
Electrostatic discharge (ESD) can damage or destroy the input circuits of the
Agilent 8702D. ESD can also damage or destroy electronic components that
you are measuring. All work should be performed at a static-safe work station.
The following figure shows an example of a static-safe work station (without
the instrument) using two types of ESD protection:
• Conductive table-mat and wrist-strap combination.
• Conductive floor-mat and heel-strap combination.
1-4
Installing the Agilent 8702D
Step 2. Set up Static-Safe Workstation
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 MΩ of
isolation from ground. Refer to Table 1-1 for information on ordering staticsafe accessories.
WARNING
These techniques for a static-safe work station should not be used
when working on circuitry with a voltage potential greater than
500 volts.
Reducing ESD Damage
The following suggestions may help reduce ESD damage that occurs during
testing and servicing operations.
• Personnel should be grounded with a resistor-isolated wrist strap before removing any assembly from the unit.
• Be sure all instruments are properly earth-grounded to prevent a buildup of
static charge.

Step 14. Copy the EEPROM Disk
The Agilent 8702D is shipped from the factory with an EEPROM backup disk
which is unique to each instrument. The backup disk contains a copy of correction constants which were stored in the instrument’s internal memory at
the factory. If your Agilent 8702D should ever be damaged, these correction
constants may need to be reinstalled from the disk. Use the following procedure to create a backup copy of the disk.

Manual Performance Tests
This chapter contains procedures which test the electrical performance of the
Agilent 8702D. If you are using an Agilent 8702D Option 011, perform the
tests in Chapter 6, “Performance Tests – Option 011”. Before starting these
procedures, allow the instrument to warm up for one hour.
Each procedure has a “Performance Test Record” that is located at the end of
this chapter.
To obtain the same quality of performance testing that Agilent Technologies
has administered at the factory, you must perform:
• the system verification procedures in Chapter 2, “Automated Verification” or
Chapter 3, “Manual Verification”.

These servicing instructions are for use by qualified personnel only.
To avoid electrical shock, do not perform any servicing unless you are
qualified to do so.
The opening of covers or removal of parts is likely to expose
dangerous voltages. Disconnect the instrument from all voltage
sources while it is being opened.
The power cord is connected to internal capacitors that may remain
live for five seconds after disconnecting the plug from its power
supply.
