• Test? (yes/no) specifies whether you want to test the UUT at this channel, for
multiple channel testing only. (If testing a single channel using the System
Information Screen, only the selected channel is tested regardless of the setting
in the Test? field). If set to “No” then the UUT will not be tested at that channel, but
you may retain the channel information in the table for later use. If set to “Yes” then the
channel will be used as defined by settings of Prime? and All Chans? fields.
• Prime? (yes/no) specifies which channels are “prime”. Select “Yes” if you want to
test the UUT at this channel on all the tests in the procedure. Select No if you want to
test the UUT at this channel on just a subset of tests, which are design ated by se lecting

Saving a Test Procedure
A Test Procedure is a collection of channel information, test parameters, testing
order, and pass/fail limits saved in a file that customizes the test software to a
specific application. You may save the file to a memory card or disk. When you
save a procedure you will be saving chann el information, t est parameter s, pass/fai l
limits, and testing order, plus a library that contains the names of all test
parameter s, pass/fail limits, and test s that are resident in the sof t ware. The library
file comes from the software and cannot be modified. The library file will be
automatically saved on the card or disk that is being used to store the new test
procedure.
The following example shows how to save a new procedure to a memory card.

Before you begin testing, you must load the software into the test set memory. To
load the software, you must first select the location to load from (in this case, it
will be
Card) and a procedure filename. Your card comes pre-programmed with
at least one procedure. The actual software program does not get loaded into the
test set memory until k1 (
Run Test) is selected. It will take approximately two
minutes for the software program to be loaded at that time.
The software memory card can be removed after the pr ogram is loade d into the
HP 8920A,D memory. The program will remain in memory after a power-down/
power-up cycle, unless it is manually deleted or a new program is loaded.
Loading a Software Upgrade, FW below rev A.12.04 only
If you have purchased a software upgrade from the factory and are loading it for
the first time, you must clear the old revision software from the test set memory
before running the new revision software. If you do not, the new re vision will not
be loaded, and the old revision will be used. This is for FW below revision
A.12.04 only. For firm ware revi sion A.12.04 and ab ove, th e test set will check for
differences in the code, and automatically load the most updated version.
The easiest way to clear the old revision software is to load a different software
program. The LIST_OPTS progra m that is sto red in int ernal ROM can be used for
this purpose.

Customizing Testing
The HP 11807A,E Software may need some customizing before it performs in a
way that is necessary fo r your t esting nee ds. Because of the diver sity of ind ividual
testing needs, the HP 11807A,E Software has been designed so that changes may
be easily made from the HP 8920A,D fr ont panel. You may store the se changes on
an SRAM card so that you may skip these steps in the future. See

• enter the channel receive frequency in MHz
• TX frequency
• enter the channel transmit frequency in MHz
• Test? (yes/no) specifies whether you want to test the UUT at this channel, for

in the Test? field). If set to “No” then the UUT will not be tested at that channel, but
you may retain the channel information in the table for later use. If set to “Yes” then the
channel will be used as defined by settings of Prime? and All Chans? fields.
• Prime? (yes/no) specifies which channels are “prime”. Select “Yes” if you want to
test the UUT at this channel on all the tests in the procedure. Select No if you want to
test the UUT at this channel on just a subset of tests, which are design ated by se lecting

tests are run is not impor tant.
This chapter describes each test and the associated parameters, pass/fail limits,
and external equipment that are required. When you first load a test procedure or
create a new test seq uence, ref er to this section to understand what para meters and
pass/fail limits are required for each test.
The tests are derived from the following industry standards:

Factory-Defined Procedures
Your HP 11807A,E software memory card comes with some procedures already
stored on it. Although many of the default parameters and pass/fail limits may be
correct for your radio, you should review and edit them before testing; especially
the General (GN) parameter s. The defa ult chann el freq uencie s will almo st always
be different from your radio’s programmed channels (since there are several
hundred possible channels).
The three factory-defined procedures are -
MANUAL
This is a single test, test 22 - RT manual test, described later in this chapter. This
test allows you to make several continuous receiver and transmitter
measurements, providing a quick functional test of one or more radios.

Introduction
Shared Parameters
Many parameters are us ed in more than on e test . For exampl e, all trans mit ter t ests
use parameter TX user/s ystem key UUT to determine how the transmitter is keyed
during tests.
Once you have entered the correct parameter value, the same value should work
with all tests that use that parameter.
Prefixes and Abbreviations: GN, RT, RX, TX, Trunked, Conv
All tests, parameters, and pass/fail li mits are prefixed by a two-letter code
representing when they are used. For example, the parameter RX audio load
impedance is used for receiver tests.
• GN: General - used to identify a group of parameters that are associated with sign aling
information or the given system selected on the radio.
• RT: Receiver/Transmitter - used to identify parameters that may be used for both
receiver and transmitter tests, and tests which make both receiver and transmitter
measurements.
• RX: Receiver - used to identify tests, parameters, and pass/fail limits used only for
receiver tests.
• TX: Transmitter - used to identify tests, parameters , and pass/fail limits used only for
transmitter tests.
Trunked/Conventional Channel References
Many tests, parameters, and pass/fail limits are unique to trunked channel testing,
and are identified by the term trunked. Example, parameter RT trunk ed sign aling
high speed deviation.
Other tests, parameters, and pass/fail limits are unique to conventional channel
testing, and are identified by the term conv. Example, parameter RX conv sque lc h
blocking.
If the name of a test, param eter, or pass/fail limit does not contain trunked or
conv, it is used for both trunked and conventional channel tests.
98
General (GN) Parameters
Before any radio tests ar e perf ormed, you must indic ate what chan nel you want to
test, and enter your radio’s pre-programmed information (area number, home
channel, squelch type, squelch code, and so forth). This information can be
provided using either of two methods:
• Entering the information on the System Information screen at the start of each
test.
• Entering the information in parameters with the GN prefix. On Rev. A.00.04 or greater,
entries of 1, 2, or 3 all s pecified trunk test ing; h owever, each entry specifies a slightly
different method of sending the trucked data to the mobile after the mobile has trunked
to a channel other than the home channel.

0 = Convention: Tests conventional FM radios.
1 = Trunk: The free channel data is set to 0. (0 is send when there are no other
channels available in the system)
3 = Trunk:The free channel data is set to the present trunked channel.
Parameter AA use GN value from [0=sys info 1=parm] allows you to set which
method to use.
Using the System Information Screen
If parameter AA use GN value from [0=sys info 1=parm] is set to 0=sys, you ar e
prompted to select the type of radio to test (trunked or conventional) and to enter
information on the
System Information screen each time you begin testing.
Use the System Information Screen if:
• you are testing different systems on the same radio with the same test sequence, for
example, trunked and conventional channels.
• you are testing several radios that are pre-programmed with different information, but
share the same channel assignments.
Using General Parameters
If parameter AA use GN value from [0=sys info 1=parm] is set to 1, the System
Information
screen is not displayed and you are not prompted to choose the
radio type. The software now get s t he ra di o inf or mati on fr om the GN parame ter s,
and testing begins almost immediately after you press
Run Test.
Use the General Parameters if:
• You are repeatedly running the same test(s) on a radio, or when running the same test
on several radios that were pre-programmed with the same information.

Introduction
Testing Multiple Channels
Multiple channel testing is initiated by us ing either of the following methods:
• To use the System Information Screen, set parameter AA use GN value from 0=sys info
1=parm] to 0=sys info.
• For a trunked system: set the working channel number = 0
• For a conventional system: set the conventional channel number = 0
• To use the Parameter table, set parameter AA use GN value from 0=sys info 1=parm]
to 1=parm.
• For a trunked system: set parameter GN choose radio type [0=conv 1=trunked] to
1=trunked. Then set parameter GN trunked working chan # [0 or 1-20; 0=all ch]
to 0=all ch.
• For a conventional system: set parameter GN choose radio type [0=conv
1=trunked] to 0=conv. Then set parameter GN conv chan # [0=all chans or 2150] to 0=all chans.
NOTE: Once a multiple channel sequence is started, all selected conventional and trunked channels
will be tested.
