Overview

 

This manual contains operating instructions for the Agilent 8494G/H,

 

8495G/H, and 8496G/H attenuators. Included in the manual is information

 

required to install and test these attenuators.

Specification

Instrument specifications are indicated in Specifications, page 6. These

 

specifications are the performance standards or limits against which the

 

instruments may be tested.

Instruments Covered by

The instruments covered by this manual have a two-part serial number. The

Manual

first four digits and letter comprise the serial number prefix. The last five

 

digits form the sequential suffix that is unique to each instrument. The

 

contents of this manual apply to instruments with serial prefixes 2544A and

 

above.

 

An instrument manufactured after the printing of this manual may have a

 

serial prefix that is not listed above. This unlisted serial prefix indicates that

 

the instrument is different from those documented in this manual.

Description

The 8494G/H, 8495G/H, and 8496G/H are 50-ohm coaxial programmable

 

step-attenuators. Each attenuator is composed of three or four attenuator

 

sections connected in cascade. Each section consists of a precision, thin-film

 

attenuator card, a lossless thru-line, and a ganged pair of solenoid-actuated

 

slab line transmission lines. The slab lines are flexed by the solenoid

 

plungers to make contact with either the attenuator card or the thru-line. The

 

slab line contacts are gold plated leaf springs which ensure long life and

 

extremely high repeatability.
