For
Automated High Speed Measurement of RF Transmission / Reception Characteristic
Test and Call Processing Test of W-CDMA Mobile Terminals conforming
to 3GPP Standards
Anritsu
Corporation (President: Akira Shiomi) announced that it is accepting
orders from September1, 2002 for its new ME7876A Mobile Communication
Test System. The system enables the automated testing of the RF[*1]
transmission/reception characteristic and call processing of mobile
terminals conforming to W-CDMA, one of 3rd generation mobile phone systems,
performed in a batch at high speed. Also, measurement parameters for
testing and test result data can be easily administrated.
The use of this system shortens the acquisition time of W-CDMA test
methods and instrument control methods, which dramatically improves
the efficiency of W-CDMA mobile terminal development and manufacturing
line configuration.
This system can be utilized for wide range of applications from characteristic
evaluation in R&D to characteristic inspection in manufacturing
line and characteristic evaluation test in maintenance of W-CDMA mobile
terminals.
[Development
Background]
The 3rd generation mobile phone system targeting at worldwide standard,
W-CDMA system, has domestically started its trial service from May 2001
and the actual service has been started from October 1. Accordingly,
W-CDMA mobile terminal developers require the automation in production/inspection
line of mobile terminals and automated test system configuration in
maintenance site for efficiency.
Furthermore, under the expectation of mobile terminals equipped with
new functions to be developed one after another, capital investment
and test process with good efficiency is a key issue for manufacturers
and carriers. Especially in manufacturing line and inspection/maintenance
line, the measuring instruments with high-speed processing and excellent
cost performance are strongly requested for more efficient line configuration.
To
meet these requests, Anritsu provides the optimum solution for efficient
development/manufacturing line and inspection/maintenance line configuration
of mobile terminals by releasing the ME7876A Mobile Communication Test
System, which was produced by know-how cultivated in the past system
development.
At the same time, Anritsu aims to provide the total test solution for
domestic and overseas W-CDMA mobile terminal development with our Signalling
Tester, Digital Mobile Radio Transmitter Tester and Digital Modulation
Signal Generator, etc. which are now available in the market.
For future, Anritsu is also planning to provide the test system solution
to totally support 3GPP standards TS34.121.
[Product
Outline]
ME7876A Mobile Communication Test System is composed of MT8820A Radio
Communication Analyzer (Anritsu) and the dedicated software. This test
system achieves RF transmission/reception test and call processing test
of W-CDMA mobile terminals conforming to 3GPP standards performed at
high speed on a single instrument.
The
dedicated software programmed on the basis of Windows2000 can easily
administrate measurement parameters for testing and test result data.
Also, this dedicated software handles all the operations ranging from
each setup for measurement to pass/fail evaluation of test results and
data administration. Thus, the use of this system shortens the acquisition
time of W-CDMA test methods and instrument control methods, which dramatically
improves the efficiency of W-CDMA mobile terminal development and manufacturing
line configuration.
In addition to various tests performable in communication (loop-back
state) with W-CDMA mobile terminals to be tested, current consumption
of W-CDMA mobile terminals can be tested with DC Power 2303 (KEYTHLEY).
MT8820A
Radio Communication Analyzer is the measuring instrument that can perform
high-speed RF transmission/reception test and call processing test of
W-CDMA mobile terminals conforming to 3GPP standards on a single instrument.
It achieves the batch measurement of major RF transmission test items
at the fastest measurement speed in the world, approx. less than 0.2sec.
[Main
Functions and Performance]
* Test methods freely selectable for each user and test data administration
Various tests can be selected such as automated batch measurement for
all test items, manual measurement for selected items and step measurement
for each item.
Also, transmission measurement easily performs the performance distribution
evaluation and statistical administration of mobile terminals to be
tested with /Avg./Max./Min. value display. Furthermore, html or CSV
format is selectable for measurement data save format.
* Test parameter setup and administration simplified by excellent operability
The dedicated software helps to rearrange test procedures and to alter
test parameters easily. Also, each altered operation parameter for testing
can be saved in files and read out when necessary.
* Operation screens with excellent visibility
Software main operation screen enables simple visual confirmation. For
instance, waveforms of measured characteristics, real-time test status
information during test, and evaluation results after testing all items
are displayed on an entire PC screen for at-a-glance confirmation.
* Software customizing
By making most of our know-how gained in the past system development,
the functions with strong request from users are equipped as standard
software functions. Also, the modularization of various measuring instrument
drivers enables the structure that allows instruments to be added or
altered easily. Thus the system can be configured (customized) according
to each user’s request.
* Functions are equipped for high-speed batch measurement of RF transmission/reception
characteristic and call processing test conforming to 3GPP standards
in communication with W-CDMA mobile terminals to be tested.
* Batch measurement of major RF transmission test items
Measurement items:
Transmission Power, Frequency Error, Occupied Bandwidth, Spectrum Emission
Mask,
Adjacent Channel Leakage Power Ratio, Vector Error, Peak Code Domain
Error
* Measurement of major RF reception test items in communication state
(loop-back state)
Measurement items:
Reference Sensitivity Level, Maximum Input Level, etc.
- The measurement in HARIKIRI[*2] is also available.
[Target
Markets and Applications]
