1. GENERAL INFORMATION

This Operating

and

Service Manual contains informa­tion about initial inspection, operation, performance
tests, adjustments, troubleshooting and repair of the

HP Model 11722A Sensor Module.

2. Specifications

Instrument specifications are listed in

Table I. These

specifications are the performance standards or limits
agninst which the instrument can be tested. The sup-

plemental characteristics listed in Table 2 are not

specifications but are typical characteristics included
as additional information for the user.

3. Instruments Covered by Manual

This inst.rumenl, has a two-part serial number. The
first four digits and the letter comprise the serial­number prefix. The prefix is

the

same for all identical
instruments; it changes only when a change is made
to the instrument,. The last five digits form a sequen­tial suffix which is unique to each instrument. The
contents of this manual apply directly to instruments

having the serial prefix l&red under Serial Numbers
on the title page.

An instrument manufactured after the printing of this
manual may have a serial prefix that is not listed on

the title page. This unlisted serial prefix indicates that
the manual for this instrument is supplied with a
Manual Changes supplement that documents the
differences.

In addition to change information, the supplement
may contain information for correcting errors in the
manual. To keep this manual aa current and accurate
as potsible, Hewlett-Packard recommends that you
periodically request the latest Manual Changes sup­plement. The supplement is identified with the man­ual print date and part number that appear on the title
page. Complimentary copies of the suppXcment are
available on request from your nearest Hewlett-

Packard office.

For information concerning a serial prefix not listed
on the title page or in the Manual Changes supple­ment, contact your nearest Hewlett-Packard office.

4. Description

The HP Model 11722A Sensor Module is essentially
an RF power sensor with an RF switch at its input.
The RF input to the Sengor Module can be remotely

switched between its power sensor and a through path
RF cable. The power sensor is used to measure the av­erage power from an external RF source.

In use, the Sensor Module input is connected to an
RF source. The Sensor Module’s two output cables are
connected to a compatible power measuring instru­ment such as the HP 8901B Modulation Analyzer of

HP 8902A Measuring Receiver. The power sensor
input is a 5OQ load to the

RF w>urce.

The power mea-

suring instrument indicates the power dissipated in
