4202R Mobile Service Tester |
Willtek Secures Railway Safety |
|
Based on the Willtek 4200,
the Willtek 4202R Mobile Service Tester is dedicated to new features
and frequency bands introduced by GSM-R, the railway communication
system based on GSM. The Willtek 4202R is the first GSM-R test
instrument for service applications, and its small size and low weight
make it the ideal choice to test and repair applications requiring
mobility.
Proper Performance Helps Emergency Situations
The
Willtek 4202R allows the simulation of group calls (VGCS) at various
priority levels. This includes emergency calls based on group calls to
verify not only the performance of the cab radios, but also of
peripherals such as optical and acoustical alarms. These tests ensure
proper performance of the radio system and help prevent disaster in
emergency cases. |
|
|
Highlights:
- Support of GSM-R specific call features, such as Voice Group Call Service (VGCS) and emergency calls based on VGCS.
- Support of specific parameters, like Group ID and call priority.
- Optional battery pack available for true mobile operation.
|
The 4202R enables the usage of different Group IDs and call priorities to simulate standard group calls or emergency calls.
During the “listener” mode the 4202R generates a 1 kHz
sine tone to verify that the phone is actually on the correct channel
(since the phone is not transmitting during “listener” mode this is the
only way to verify proper behavior)
During the “talker” mode the 4202R measures the RF coming from the phone, in that way verifying proper performance of the phone.
After an emergency call the 4202R supports the reception of status messages coming from the phone.
Applications
Service/Installation of GSM-R radios
The 4202R is specifically tailored to railway applications. The
4202R can be used during installation of cab radios, as well as for
repair and final test of GSM-R terminals. The 4202R can optionally be
battery-powered so that it is truly mobile which simplifies the use on
an engine.
These features enable railway organisations not only to test their
GSM-R terminals, but also allow the verification of important
peripherals, such as indicator lights or horns for incoming emergency
calls.
