About the Test Software
About the Test Software
The HP 11807B Option 040 Motorola AMPS/NAMPS Cell Site Test Software is
used with the HP 8921A Cell Site Test Set, and various ancil lary equipment, to
test the functionality of Motorola cellular telephone base stations. The Test
Software package, as shippe d, co ntains the following items:
• HP 11807B Option 040 Cell Sit e Tes t So ftware Card, part number HP 11807- 10012
• HP 11807B Option 040 Test Software User’s Guide, part number HP 11807-90153
• Software licensing agreement, part num ber 5180-1566
• 128-kilobyte Memory (SR AM) Card (part num ber HP 85702A) for st oring customiz ed
tes t pr o gram s and resu lts.
• Cable and adap tor for serial connection to the base station
• 6-Conductor RJ11 (m) — RJ11 (m) cable, part number 08921-61015
• RJ11 (f) — DB25 (m) adaptor, part number 08921-61016
The following features of the Test Softwa re simplify testing:
• The Test Software sends base station control comma nds automaticall y fr om th e Tes t
Set via the RS-232 interface . The Test Softwa re also displays responses from the base
station.
• The Test Software displays the location of an adjustment whenever adjustment is
required.
• The Test Software displays a large meter on the Test Set screen and provides variabl e
auditory feedback while adjustments are being made.
• The Test Software displays system interconnects on the Test Set screen whenever cable
connections mus t change.
• The Test Software displays results of test s and pas s/fail indicat ions on the Test Set
screen, and supplies the results and indications for printing or collecting in an HP
Palmtop comp u t er, a P C , a di s k driv e , or a memory (S R A M ) ca r d .
• The Test Softwar e co n trols switche s that se lect the external RF or audio signal paths.
• The Test Software allows you to cha nge the order of TESTs, pass/fail limits,
parameters, and extern al device configurations.
• The Test Software provi des that bas e stat ion control command s can be sel ecti vely sen t
as the tests proceed.
• The Test Software pr ovides t ha t RF pa th losse s ca n be det ermined and a ccommod ated.

About the Test System
Chapter 1, Product Description
About the Test Sy stem
When the Test Software is used with the HP 8921 A Test Set and the various other
equipment, the combined system is called the Test System. The following items
make up the Test System:
• HP 11807B Option 040 Motorola AMPS/NAMPS Cell Site Test Software.
• HP 8921A Cell Site Test Set.
• Accessories:
• HP 83202A Option 040 Base Station Accessory Kit.
or
• Other switch and in terconn ect arrangements.
In addition, it would be helpful to have available the RF Tools in the HP
11807A,E Option 100 System Support Tests software package. The Option 100
software package offers a range of tests that may be used as adjuncts to those in
the Test Software.
Note that the following thre e tests that were in previous versions of the Test
Software w ere rem o ved fo r this version (B.01.00):
• VSWR Swept Return Loss.
• VSWR Discret e Channel Return Loss.
• VS W R vs D ist an ce (cabl e f au l t)
Product Description
Chapter 1
These tests are now included the RF Tools section of Option 100 software
package.
This system performs tests that determine the quality of the RF and audio
performance of several types of Motorola AMPS and AMPS/NAMPS cellular
base stations. Most of the measuremen t methods and specific ations use d for these
tests are derived from Electronic Industri es Association st andards and procedures
recommended by Motorola.

Chapter 1, Product Description
Testable C el l Site Eq uipment
Testable Cell Site Equipment
The Test System allows you to test Motorola HDII, HDII/NAMPS, and LD Base
Stations. The firmware revision of the bas e station to be tested must be 4.3.2.1 or
higher.
Specific equipment that you can te st includes voice transceivers, scan receivers,
signaling transc eivers, combiners, power amplifiers, and universal refere nc e
distribution modul es. The Test Software includes major adjustment procedures.

Using the Test Software
Chapter 1, Product Description
Using the Test Software
IMPORTANT
CAUTION:
This Test Software can be used during routine cell site verification and after the
installation or repair of cell site equipment. Base stations can be tested while in
the In-Service Optimiz at ion Mode or in the Manual Mode. The Manual Mode
must be used for some of the TESTs. There are instances in which it may be
advantageous to choose one of these modes over the other.
Before you connect the Test Set to a base station, you should underst and the potential
results of your act ions. Dropped calls, accidental modification of base stati on calibration
data, and other undesirable effects can occur.
The next two sections will get you started learning to use the Test Software. The
first of the two, “Getting Started”, contains steps to follow if you have not run
Test Software on a Test Set. The second of the two, “Learning to Use the Test
Software”, describes steps that you should follow in continuing to learn to use the
Test Software.

Firmware D ifferences
Firmware Differences
Firmware revision A.14.00 in the HP 8921A,D Cell Site Test Set introduced
several enha ncements to the TESTS menus. Wit h th e enhance ments were cha nges
to the menu structure used in the TESTS (Main Menu) screen and its sub-screens.
This manual is written for instruments with firmware revision A.14.00 and
higher. To assist users with instruments with older firmware, this section
summarizes the change s and shows the corr espondenc e between revis ion A.14 .00
screens and those of the earlier versions.

NOTE: If you are unsure of the firmware revision of your unit, press and release the SHIFT key
then press the DUPLEX key. A configuration screen will be displayed and the firmware
revision is sho wn in the upper right of the screen. Contact Hewlett-Packard at

Using the TESTS
Menu Comparison
NOTE: The information in * and ** are for use rs of Test Sets with firmware revisions below
A.14.00. Please dis regard this materia l if your Test Set has a firmware revi sion of A.14.00
or higher.
The next two figur es show the TESTS (Main Menu) sc reens for the latest TESTS
menu (figure 1 ) and the TESTS menu used in older firmware revisions
(figure 2 ). The illustrations are intended to help you find the corresponding
functions if you are working with older firmware revisions.
To use the comparison, follow these steps:
1. When you enc ounter a procedure or diagram referring to a TESTS (Main Menu) field
selection or name that d oes n ot appe ar on your T ESTS (Ma in Menu) (or ma y a ppear i n
a different location on the display), refer back to these figures.
2. Loo k for t he sel ection desc ript ion or na me in figure 1 and no te the corres ponding l etter .
3. Look for the same letter in figure 2 and note whic h field (or sub-menu) is used in the
older firmware to access the screen or field.
4. Once in the sub- menus, the old a nd new scree ns are very similar a nd you shoul d be able
to use the docu me ntation as-is.
