Racal Instruments 6113E

The Racal Instruments Wireless Solutions (RIWS) 6113 Digital Radio Test Set provides a wide range of test and measurement functions to enable fast manual or automatic testing of GSM850, GSM900, GSM1800 or GSM1900 Base Transceiver Stations (BTSs). Applications includes installation and commissioning, routine maintenance, fault diagnosis and final unit product testing. The Base Station On-Air Service System (BOSS) allows live RF network traffic monitoring and analyzing. It can set up calls for receiver testing. A sensitive measuring receiver option permits operation remote from the antenna. · Comprehensive Test of Transmitter and Receiver · Easy to use, fully integrated, soft key driven BTS test set · Support for GSM850, GSM900, GSM1800 and GSM1900 · Comprehensive test of transmitter and receiver · Options to control all major BTS types · Manual and fully automatic testing · Test sequences for full customization · Optimized for installation and commissioning, routine maintenance, fault diagnosis and production testing · A-bis interface for full BTS control and bit error ratio (BER) measurements · Two PC Card slots for data storage, field upgrades and software enhancements A-BIS INTERFACE In order to perform comprehensive, “real environment”, stand-alone testing of a base station, the test set must be capable of controlling the BTS. The 6113 is unique in its ability to measure RF transmissions as well as connecting to the BTS via the A-bis interface. Through the use of the specific BTS manufacturers’ Operation & Maintenance (O&M) commands, the 6113 is able to emulate the Base Station Controller (BSC) and take complete control of the BTS. This is accomplished automatically without the need for user intervention. The A-bis interface also allows the user to make Bit Error Ratio (BER) measurements on both the receiver and transmitter, as specified in GSM rec 11-20/11-21. The 6113 A-bis interface also permits a wide variety of other test functions to be performed that could not otherwise be done. The A-bis interface of the 6113 supports a bi-directional communications and control link at either 2.048 Mbit/s (CEPT standard) or 1.544 Mbit/s (US T1) standard. With one traffic channel and two signaling channels of either 16 or 64 kbit/s, the 6113 accommodates the fact that the mapping of traffic and signaling channels are manufacturer specific.
