For Performing Area Tests and Maintenance of W-CDMA and GSM Base Stations
For Performing Area Tests and Maintenance of W-CDMA and GSM Base Stations
The ML8740A Area Scanner is a scanner for performing driving tests for optimizing base station service areas.
Because of its excellent hardware performance, it can be used to for accurate area-coverage tests even in severe
measurement environments with high interference because it can obtain radio wave carrier characteristics with
high reliability.
When used in combination with the Two Carrier Measurement Function and GSM Measurement Software options,
either two W-CDMA base stations on different frequencies or a W-CDMA and GSM base station can be measured
simultaneously.
The data collection efficiency for drive testing is greatly improved compared to earlier products.
Furthermore, installing the BCH Demodulation Software option permits confirmation of cell traffic data and base
station settings, offering support for discovering base stations with insufficient traffic capacity, and preventing
configuration errors.
Correlation with GPS Positioning Data
When the GPS receiver is connected, measurement data is
recorded with GPS positioning data (latitude and longitude).
Simultaneous W-CDMA and GSM Measurement
Installing the optional ML8740A-001 Two Carrier
Measurement Function and the MX874002A GSM
Measurement software enables simultaneous W-CDMA and
GSM measurement. The data collection efficiency for drive
testing is greatly improved.
Checking broadcast information by BCH
demodulation
For W-CDMA measurement, the W-CDMA base station
BCH data can be obtained via the MX874001A application
software without using the UE. Since the uplink
interference power corresponding to the measured CPICH
value is displayed in real time, cell traffic data can be
checked. And since all SIBs (System Information Blocks)
are supported, it is possible to check whether the base
station parameters are set as designed.
Simultaneous Measurement of Two Carrier
Frequencies and Diversity function
By using the ML8740A-001 Two Carrier Measurement
Function option, two carrier frequencies can be measured
simultaneously.
In addition, the W-CDMA transmission diversity format
RSCP of the CPICH can be measured by using the
diversity function.
Specific distance measurement using car speed
pulses
When a car speed pulse is used as an external trigger,
measurements can be performed at specific distances.
The measurement period can be designated by the pulse
count or distance when measuring using the external
trigger.
High-speed and High-accuracy Area Analysis
RSCP, Ec/No, and SIR can be measured at 30 cm intervals
(using specified base station and single-channel measurements) while traveling at 100 km/h in a monitoring vehicle
to provide fast and accurate area analysis.
5-hour Battery Operation
In the standard configuration, the lithium-ion battery pack
provides 5 hours of operation and a spare battery pack
solves even long-term measurement problems.
High-speed Search with SCH
When SCH search is selected in unspecified base station
mode, CPICH can be searched at high speed using the
same SCH search method as a UE. As one measurement
example, 10 channels are searched for 4 sec on average
and then the measurement is started.

High Interference Resistance
The ML8740A is ideal for designing optimized area coverage because its high hardware performance enables it to
obtain the characteristics of radio-wave carriers with high reliability even in areas with high interference, such as in
cities.
The ML8740A has a very wide level measurement range and obtain true levels with almost no error, unlike
scanners with an inadequate measurement range, which give average levels that are larger than the true levels.

Time
When designing an area using a scanner with an inadequate measurement range, errors occur because the
coverage seems wider than the true area coverage, resulting in the likelihood of an incomplete area design with
some parts having no coverage.
Today’s market requires a scanner like the ML8740A with high-level accuracy supporting exact area design.

Standard Measurement Functions
Unspecified Base Stations (W-CDMA)
Spectrum Monitor
Receiving CPICH channels are searched for and RSCP,
Ec/No, and SIR are measured for a maximum of 32 channels. The search method can be either the same SCH
method used by the UE or the Primary CPICH (P-CPICH)
method, which searches up to 512 types of P-CPIC in
sequence. Moreover, by using the hybrid measurement
function for measuring the searched CPICH and preset
scrambling code CPICH, known channels can be measured
while discovering and measuring other receiving channels.
This function performs in-band spectrum analysis to check
for interference waveforms. Either 4, 10, 30, or 60 MHz can
be selected.
CW Measurement
Non-modulated signals can be measured with a resolution
bandwidth of 15 kHz.
The minimum measurement period is 10 ms. The average
and median values are output to a connected PC along with
the measurement time and GPS positioning data.
Specified Base Station (W-CDMA)
A maximum of 32 P-CPICH and Secondary CPICH (SCPICH) channels can be specified and RSCP, Ec/No, and
SIR can be measured in the same way as unspecified base
stations.
Fixed Distance Measurement using Car Speed Pulse
When the speed pulse from an automobile is used as an
input trigger, measurement data can be obtained at fixed
distance intervals. When the previous speed pulse
generation interval is calibrated using the external trigger
calibration function, the required distance interval for the
measurement cycle can be set directly instead of setting the
pulse count.
Delay Profile Output (W-CDMA)
This function measures the delay profile of the selected
channel to confirm the multipath delay time and relative
level.
Finger Output (W-CDMA)
This function outputs the measurement results for each
selected channel path (finger). When the ML8740A-001
option is installed, the RSCP of up to 12 paths can be
evaluated simultaneously.
