TM506 Support of Option Globetrotter Express HSUPA World Support of Samsung SGH T819 External antenna solution can now be offered for new or existing Sony Ericsson Z750i terminals FAB 801 8764 External antenna for Z750 New FAB 801 8765 External antenna for Z750 Retrofit Note This is a hardware modification and will always require external antenna to be connected Both packages will include the external antenna For more information contact your closest TEMS Support office Known Bugs and Limitations PC Application Related General Installation When running multiple installations different versions of TEMS Investigation on the same machine each installation needs to be put in its own directory If the installation program encounters an existing installation it will automatically suggest a different directory for the new installation If you have mistakenly installed one product version on top of another uninstall all applications and then reinstall each application to a unique directory The application start up time may be prolonged if slow network shares are mounted on the machine General Vista Data Collection Aero Glass should be turned off for performance reasons User Access Control needs to be turned off to allow IP trace It may also need to be disabled for other reasons depending on its configuration Error dialog about writing in Windows registry appears when starting GeoSet Manager gst files can ho
4. The maximum database size in RAN Tuning is 2 GB To avoid long processing times in RAN Tuning tool the selected cell files clusters should match as closely as possible the area where the selected logfiles were recorded The route in the Map window is moved when opening a slave map The Map window does not have any tooltips for its toolbar buttons In the Map window data is displayed differently depending on which of the plotted routes is stepped through No default map is loaded in Route Analysis Map window The replay function in Route Analysis often executes very slowly Manually stepping through the route with the keyboard arrow keys can be faster The cache in Route Analysis should be cleared when a new release is installed to avoid misleading results How to do this is described in the Route Analysis User s Manual section 5 5 Clearing the Logfile Cache The spider cursor in the Route Analysis map does not show values for CDMA and EV DO related data Processing logfiles with Python scripts from the Converter tool does not work A workaround is to run the scripts from the Windows Command Prompt Phone Related Sony Ericsson K800 K790 Z750 The driver software for the memory stick needs to be installed on the PC to avoid problems when connecting a phone that is turned off If the K790 K800 has a memory stick do as follows when first connecting the phone Insert the USB cable Wait for drivers to install Unplug and ins
5. previous versions of Route Analysis will crash the Route Analysis application Only workspaces from this version will load The legend in the Map window flickers when items are selected deselected Whenever a checkbox on the Legend tab is checked or unchecked the contents of that window pane are redrawn Changing the presentation in a slave map window sometimes adds an offset to the plot in the master window from which the slave was created An easy workaround is to close the slave refresh the master and open a new slave The spider cursor does not show at the outset in the Map window nor does it appear when selecting objects directly on the map However when a sample is selected in a different presentation window e g a line chart or a message window the spider cursor does appear around the corresponding point of the route Events in the MID MIF files generated by the RAN Tuning tool may sometimes be associated with the wrong MS DC device For example a RAS Dial event from DC1 may be given as originating from MS2 in the MID MIF files UE Event Plot Care should be taken when comparing for example events in the RAN Tuning report with events shown during replay in Data Collection RAN Tuning calculates event statistics only on complete calls and data sessions Calls and data sessions that are set up before the logfile recording is started or end after the logfile recording is stopped are not used for calculating event statistics

8. single frequency measurement When scanning four frequencies the sample rate is decreased to only one measurement per frequency over a two second period which means that it no longer makes any sense to choose the Sub data mode It is then better to choose the Full data mode and also get the synchronization channel measurements The PCTel scanners may sometimes report many scan drop messages The scanner uses this message to tell the host how many scan data messages were dropped and not delivered through the data link Automatic scan data is dropped when the scanner is scanning faster than the data can be delivered through the data link causing the pipeline to overfill GPS Related While in dead reckoning mode Garmin Street Pilot 2650 labels its calculated positions as invalid in the PC interface yet presents the positions on its display without any such indication The positions calculated by dead reckoning are indeed mostly useful and enable TEMS Investigation to plot the route reasonably correctly when GPS coverage is temporarily lost To make use of the invalid positions you need to turn on an option in the GPS window properties see the Data Collection User s Manual section 20 1 The events GPS Connected and GPS Disconnected are intended for drive testing and are generated only during recording They do not appear during replay and post processing The positioning capabilities of the USB GPS KRE 105 074 may no
