10 Agilent 8494/95/96A/B Attenuators Operating and Service Manual

1 Introduction

Product Overview

Agilent 8494A/B, 8495A/B, and 8496A/B are 50- ohm coaxial

step attenuators.

For the 8494A/B, the attenuation can be varied in 1 dB steps, or

10 dB steps for the 8495A/B and 8496A/B. The attenuation shown

on the control knob is the additional attenuation added in the

signal path over the insertion loss of the attenuator in the 0 dB

position.

•Agilent 8494A/B instruments are four- section attenuators with a

range of 0 dB to 11 dB in 1 dB steps.

•The 8495A/B is a three- section attenuator with a range of 0 dB

to 70 dB in 10 dB steps.

•The 8496A/B is a four- section attenuator with a range of 0 dB

to 110 dB in 10 dB steps.

The attenuator sections are connected in cascade. Each section

consists of a precision, thin- film attenuator card, a lossless

thru- line and a ganged pair of edge line transmission lines. The

edge lines are flexed to make contact with either the attenuator

card or the thru- line. The edge line contacts are gold- plated leaf

springs which ensure long life and high repeatability. Low- torque

cams flex the edge lines. Table 8, “Attenuator Switching Order,” on

page 22 shows the switching arrangements.

CAUTION

Do not exceed the RF power rating of 1 W average or 100 W peak with a

maximum pulse width of 10 µs. Do not connect an attenuator RF input or

output connector to greater than ±7 Vdc. If the attenuator must be connected

to a device with a potential greater than ±7 Vdc, use a blocking capacitor.
