AT A GLANCE The R&S®Series4200 represents the latest generation of stationary radios for air traffic control. Possible applications range from small airport emergency systems requiring only a few radio channels to countrywide communications systems with several hundred radio channels. Equipment for the VHF and UHF frequency ranges The R&S®Series4200 is available in six versions. Rohde & Schwarz offers trans eivers, transmitters and c c ompact receivers for the VHF frequency range (112 MHz to 156 MHz) and the UHF frequency range (225 MHz to 400 MHz), ensuring the communications with all types...

Up to seven VoIP sessions can be established to the r eceiver or transmitter, allowing multiple VCS or emote r audio units to access the radio simultaneously. The adio r can be connected to a maximum of two VoIP voice recorders. One of the highlights of the R&S®Series4200 is the r eceiver's ability to detect simultaneous transmissions and alert air traffic controllers. Simultaneous transmissions most often occur on radio channels with high traffic v olume and can present a safety risk. frequency range from 112 MHz to 156 MHz ►► UHF frequency range from 225 MHz to 400 MHz ►► Output power of 50 W...

EASY TO USE EVEN N CHALLENGING I ENVIRONMENTS Particularly in the civil sector, air traffic control laces very demanding requirements on the radios p used. The VHF radios are operated under conditions involving significant RF interference. High-quality communications are required even in the presence of strong interference. Of course, the radios themselves should generate as little interference as ossible. p Demanding system requirements of civil air traffic control are met or exceeded Adjacent-channel power better than required by ETSI standard The transmitters and receivers of the R&S®Series4200...

MAINTENANCE-FREE OPERATION The radios of the R&S®Series4200 are designed for maintenance-free operation. They adapt automatically to the current ambient conditions and offer different functions for remote monitoring and remote control. This nearly eliminates the need to perform on-site maintenance work on the radios. Extensive self-test routines Easy remote switching when using redundant radios Extensive monitoring routines (continuous built-in tests, CBIT) run in the background to keep the user always i nformed about the status of the equipment. More than 80 parameters are monitored and any...

STRAIGHTFORWARD OPERATION AND CONFIGURATION The radios of the R&S®Series4200 offer many diverse functions that help ensure straightforward, secure and error-free operation. PC based tools with graphical user interface Warning messages in case of unauthorized local operation The radios are configured using the service PC's graphical user interface in conjunction with the R&S®ZS4200 service and maintenance tool. There is no need to open the radio, e.g. to make configuration settings using DIP switches or jumpers. Different configurations can be created on the PC for subsequent on-site loading into...

FLEXIBILITY FOR SYSTEM INTEGRATION The radios of the R&S®Series4200 provide lexibility when connected to a voice communications ystem f s (VCS) and a management system. Software pgrades ensure future viability of the radios. u Adaptation of in-band signaling for PTT and squelch to existing voice communications systems Flexibility in management system selection The in-band signaling for PTT and squelch can be adapted to existing voice communications systems (VCS), making it unnecessary to reconfigure or exchange any of the VCS components. The radios of the R&S®Series4200 can be controlled and...

R&S®RCMS II remote control and monitoring system for the R&S®Series4200 radios. The radios also support the SNMP MIB as defined by E UROCAE in ED-137B part 5, which can be used in p arallel with the R&S®Series4200 MIB. The SNMP MIB, unlike the basic MIB from EUROCAE, allows the setting of all parameters. Seamless transition from analog to digital voice transmission in the ground segment In many countries, analog connections for linking the r adio sites will soon no longer be available. In these cases, the voice signal will be transmitted digitally over 2 Mbit/s connections. The R&S®Series4200...
