About this Manual

We’ve added this manual to the Agilent website in an effort to help you support

your product. This manual is the best copy we could find; it may be incomplete

or contain dated information. If we find a more recent copy in the future, we will

add it to the Agilent website.

Support for Your Product

Agilent no longer sells or supports this product. Our service centers may be able

to perform calibration if no repair parts are needed, but no other support from

Agilent is available. You will find any other available product information on the

Agilent Test & Measurement website, www.tm.agilent.com.

HP References in this Manual

This manual may contain references to HP or Hewlett-Packard. Please note that

Hewlett-Packard's former test and measurement, semiconductor products and

chemical analysis businesses are now part of Agilent Technologies. We have

made no changes to this manual copy. In other documentation, to reduce

potential confusion, the only change to product numbers and names has been in

the company name prefix: where a product number/name was HP XXXX the

current name/number is now Agilent XXXX. For example, model number

HP8648A is now model number Agilent 8648A.

Safety

Considerations

Warning

Before this instrument is switched on, make sure it has been

properly grounded through the protective conductor of the ac

power cable to a socket outlet provided with protective earth

contact.

Any interruption of the protective (grounding) conductor, inside

or outside the instrument, or disconnection of the protective

earth terminal can result in personal injury.

Warning

There are many points in the instrument which can, if contacted,

cause personal injury. Be extremely careful.

Any adjustments or service procedures that require operation

of the instrument with protective covers removed should be

performed only by trained service personnel.

Caution

Before this instrument is switched on, make sure its primary power

circuitry has been adapted to the voltage of the ac power source.

Failure to set the ac power input to the correct voltage could cause

damage to the instrument when the ac power cable is plugged in.
