TEST PROCEDURES
Testing a SONY CM-Mx300/CM-Bx200 (Analog Only) on a
HP8920B
The following pages illustrate how to set up and perform
basic Analog Cellular tests on a SONY CM-Cx300CM-Bx200
Handset. The step-by-step instructions are for those
unfamiliar with the SONY CM-Mx300/CM-Bx200 Handset
or with a HP8920B Radio Test Set. The tests discussed are
general tests that can be used to determine if the Handset is
operating properly. This does not reflect all of the tests
needed to fully test cellular specification compliance.
Getting Started
1.
Turn on the Hewlett Packard HP8920B Radio Test Set
making sure that the memory card with the EIA-800
software is installed in the card drive, and wait for it to
go through its initialization routine.
2.
Press the “SHIFT” + “CANCEL” + “TESTS” keys on the
front panel of the HP8920B to access the Test Screen. See
Figure 1 for a picture of the Test Screen.
3.
Select the field under “Location” and change the setting
to “card” if it is not already on that setting.
4.
Select the field under “Procedure” and change the setting to
“MANUAL” if it is not already set on that setting. Make sure
the file name “Na_CELL” is displayed under the field
“Library.”
5.
Select the field under “Customized Test Function” and
change the setting in the “Test Parameter.”
6.
Find “CP control channel.” Change the setting to the
Handset’s active NAM, “1
st
Paging Channel” value. See
“Service Programming SONY’s CM-Mx300/CM-Bx200
Handset” for more information.
7.
Find CP SID number. Change the setting to the
Handset’s active NAM, “HOME SYSTEM ID” value. See
“Service Programming Sony’s CM-Mx300/CM-Bx200
Handset” for more information.
8.
Find “RT external pad and cable loss.” Change the
setting to reflect the Test Jig and cable loss between the
Handset and the HP8920B.
9.
Press the “TESTS” key on the front panel of the HP8920B
to return to the Test Screen.
10.
Press the “K1” soft key on the front panel of the
HP8920B to execute the “Run Test” command. Wait for
the test to be loaded from the card. Once the test is done
loading you will see a call processing flowchart with the
title at the top of the display: “TESTS (IBASIC
Controller).”
11.
Insert the Standard Test Jig Cable between the Audio
Break-Out Box connector and the base of the Standard
Test Jig as shown in Figure 2.
12.
Insert the Handset into the Test Jig as shown in Figure 3.
13.
Connect the Audio Break-Out Box and the Test Jig to the
power supply and then to the HP8920B as shown in
Figure 4.
14.
Press the “POWER” key on the Handset and wait for
the Handset to power up. After the Handset has
detected the signal from the HP8920B, it will sense
that it is in its Home System and you will see the RSSI
indicator display a strong signal. If the roaming
indicator “R” comes on, then the settings in the
HP8920B may be wrong.
Power Level Measurements
15.
Press the “K2” soft key on the front panel of the
HP8920B to execute the “Register” command. The
HP8920B display will show the Handset’s telephone
number and ESN if the test was a success. Registering
will take a few seconds. While the Handset is
registering, the call-processing flowchart on the
HP8920B screen will highlight the word
“REGISTRATION.”
16.
Once the Handset has registered to the HP8920B,
press the “K1” soft key on the front panel of the
HP8920B to execute “Page” command.
17.
Press the “SEND” key on the Handset when it starts
ringing. This will answer the call. The HP8920B
display screen will highlight the flowchart word
“VOICE CH” once the call connection has been
established.
18.
Once the talk timer on the Handset starts
incrementing the elapsed seconds, press the
“CANCEL” key on the front panel of the HP8920B.
Then select the “RF GEN” setting from the “To
Screen.” The display screen on the HP8920B will
change but the call will remain in process. See Figure
5.
19.
Change the units of power on the setting “TX Power”
to “dBm.” Note the Handset’s transmitted power level
and frequency error. They should be within
specification limits.
20.
To change the Handset’s transmitted power level,
press the “PREV” + “K2” keys on the front panel on
the HP8920B. This will return you to the call
processing flowchart screen and will continue the call.
Press the “K4” soft key to execute the “Chng Pwr”
command.
21.
Enter the desired power level (from 0 to 7). Press the
“ENTER” key on the front panel of the HP8920B. The
new power level number will be displayed on the call
processing screen.
22.
Repeat step 19 to see the new transmitted power level
from the Handset.
23.
Repeat steps 18, and 21 through 23 to check the
Handset’s transmitted power level settings.
24.
When you are done checking the Handset's RF power
output level and the “RF GENERATOR” screen is
present, press the “PREV” + “K2” keys on the front
panel of the HP8920B. This will return you to the call
processing flowchart and continue the call.
