About the 2201R Mobile Tester
The Cobham 2201R Mobile Service Tester is designed to test the features and frequency bands introduced by
GSM-R, the railway communication system based on GSM. The specific design of the 2201R’s RF front end allows
direct connection to GSM-R device types including the high powered Power Class 2 cab radios.
The 2201R features 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 cab radios but also of peripherals, such as optical and
acoustical alarms. These tests ensure proper performance of the overall radio system and help to verify the safety
function in an emergency.
About remote control of the 2201R Mobile Tester
Cobham provides a PC-based software, the 7310 Lector and Scriptor family of test automation programs. This
software already includes standard test sequences for remote control of the 2201R Mobile Tester. In addition, 7315
Scriptor includes a menu-driven test script editor that allows you to modify existing test sequences or generate your
own ones.
For remote control through Lector or Scriptor, please refer to the 2201R Mobile Tester User Guide (part no.
47090/322) and to the 7310 Lector and Scriptor User Guide (part no. 47090/223).
If these remote control capabilities are not sufficient for your purposes or if you want to integrate the 2201R Mobile
Tester into a larger test setup with remote control of various devices, this manual helps you to set up the system and
to write your own remote control software.
