Attenuator Overview
Safety Considerations
WARNING
General Information
The 8498A is a 30 dB, 30 W (25 W between +35
attenuator with Type N connectors. Either connector may be used as the
input or output connector.
•
The attenuator is designed to work in a 50 ohm system, and operates
over the frequency range from dc to 18.0 GHz.
•
The attenuator may be used (1) to reduce a high power signal to a level
that is compatible with sensitive equipment, (2) to reduce reflections, or
(3) as a known attenuation for substitution.
Instruments Covered By Manual
The attenuators covered by this manual have a two-part serial number. The
first four characters constitute the serial number prefix. The remaining digits
form the sequential suffix that is unique to each attenuator.
The contents of this manual apply directly to the attenuators having the serial
prefix US91. An attenuator manufactured after the printing of this manual
may have a serial prefix that is not noted above. This unlisted serial prefix
indicates that the attenuator differs in some respect from the information in
this manual.
Warranty
The attenuator is warranted and certified as indicated on the warranty page
of this manual. For further information, contact the nearest Agilent
Technologies Sales and Service office. Refer to
page
v.
The attenuator is warranted only when it is operated within its specifications.
This is especially true of power handling capability. Any attenuator returned
to Agilent Technologies under warranty will be examined carefully to
determine if the failure was possibly due to improper use.
The warning that follows is related to possible personal injury.
The high power attenuator card has a substrate of beryllium oxide. Beryllium
oxide in a powder form is a hazardous material and may be injurious to your
health if inhaled. Do not perform any operation on the beryllium oxide that
might generate dust. Defective attenuator cards should be returned to Agilent
Technologies for proper disposal.
