General Information

Warranty

The power sensors are warranted and certified as indicated on the inside
cover of this manual.

Instruments Covered by Manual

These instruments have a two- part serial number: the prefix (two letters and
the first four numbers), and the suffix (the last four numbers). The two letters
identify the country in which the unit was manufactured. The four numbers
of the prefix are a code identifying the date of the last major design change
incorporated in your Agilent Technologies product. The four- digit suffix is a
sequential number and, coupled with the prefix, provides a unique
identification for each unit produced. The contents of this manual apply
directly to all serial numbers unless otherwise indicated.

Description

The E4412A and E4413A power sensors are diode power sensors. They are
intended for measurement of CW microwave power levels in a wide
dynamic range from - 70 dBm to +20 dBm (100 pW to 100 mW). The
E4412A measures at frequencies from 10 MHz to 18.0 GHz. The E4413A
measures at frequencies from 50 MHz to 26.5 GHz. These are high- speed
power sensors, and do not incorporate narrow- bandwidth averaging used in
average- power sensors. Signals with digital, pulse, or other forms of
amplitude modulation may introduce measurement errors. Multi- tone signals
(containing multiple frequency components), or signals with significant
harmonic content (> - 45 dBc) may introduce measurement errors at high
power levels. (Specifications for the power sensors are in
