instruments Covered by Manual
This instrument has a two-part serial number. The
first four digits and the letter are the serial number
prefix. The last five digits form a sequential suffix
which is unique to each instrument. The contents
of this manual apply directly to instruments hav-
ing the serial number prefix listed under SERIAL
NUMBERS on the title page.
An instrument manufactured after the printing of
this manual may have a serial number prefix that
is not listed on the title page. This unlisted serial
number prefix indicates that the manual for this
HP 84811A
instrument is supplied with a Manual Changes sup-
plement that documents the differences.
In addition to change information, the supplement
may contain information for correcting errors in the
manual. The supplement for this manual is keyed
to this manual's print dateand part number, both of
which appear on the title page.

Description
The HP 84811A is a Peak Power Sensor. With
a compatible peak power meter it measures power
levels in a range from 0 to +20 dBm (1 mW to 100
mW), and at frequencies from 100 MHz to 18 GHz.
Compatible meters are the HP 8900C and HP 8900D
Peak Power Meters.
CAUTION
The HP 84811A Peak Power Sensor has a
maximum peak power rating of +24dBm
(250 mW). Maintaining an input power
devel of 920 mW far langer than five (5)
minutes or exceeding the maximum peak
power rating may cause severe compo-
nent damage.
NOTE
The diode (UI) is easily replaceable.
Hewlett-Packard recommends that re-
placement diodes be kept as spares if the
HP 84811A is used in applications where
inadvertent high power overload might
occur.
For instructions on disassembly and ያድ
assembly of the HP 84811A, refer to the
service section of this manual.
Recommended Test Equipment
Table 2 lists the test equipment recommended to
check, adjust, and troubleshoot the Peak Power
Sensor. If substitute equipmentis used, it must meet
or exceed the critical specifications.
