PARK AIR ELECTRONICS T6R VHF RECEIVERDescriptionDigital Multimode ReceiverPARK AIR ELECTRONICSFEATURESAnalogue and Digital programmable modulation modesAM voice with 25 kHz and 8.33 kHz channel spacingAM-MSK for Mode 1 (ACARS) D8PSK for Mode 2 (CSMA) and Mode 3 (TDMA)Exceptional dynamic range and co-location performance Compact 2U high rack mounting packageClass leading RF performanceStatic and dynamic BITThe T6 Series represent the latest generation of Park Air ATCradios which are designed for professional applications in airportand en-route centres. The T6 Series fulfils both analogue (AM)modulation and the future digital (D8PSK) modes, which arebeing planned by ICAO. The T6 Series makes extensive use ofadvanced DSP (digital signal processing) technology to enable thetransition from analogue to digital modulation modes to be madevia software upgrade. Investment in radio systems is thereby pro-tected against obsolescence as new digital modulation waveformsare introduced. The T6R operates in the VHF aviation band and provides both25KHz and 8.33KHz channel spacing. A 100 channel memory isincorporated for recall of pre-set frequency and operating modesin multichannel applications. All demodulation is implemented using DSP algorithms, whichprovide consistent long term performance. D8PSK digital modula-tion waveforms require high performance demodulators toensure reliable synchronisation and low BER (bit error rate) atlow signal levels. The T6R employs specially developed algo-rithms allied to high performance RF circuitry to ensure optimumperformance in this critical area. Control of receiver operating parameters can be effected locallyusing a menu driven front panel LCD or remotely via serial portson the rear panel. All receiver adjustments are under softwarecontrol and can be accessed externally avoiding any necessity toremove covers during the operational life of the equipment.Should software updates be required to support new modulationmodes in the future, these can be simply effected via a front paneldiagnostic port or remotely via rear panel serial ports.The T6R has comprehensive BIT which monitors both static(supplies etc) and dynamic (S+N/N, etc) parameters. A noveltechnique provides an accurate assessment of receiver sensitivityusing BIT. Results can be viewed on the front panel LCD and aresummarised via READY and ALARM indicators. All BIT data isavailable for remote monitoring via the serial ports and receiverscan be readily networked for remote monitoring using PAEMARC or similar systems.The receiver is a compact 2U 19” rack mounted unit. Power canbe 110/220 VAC or 24/28 VDC, with automatic switching to DCin the event of an AC failure. Both inputs are fully filtered andprotected.
