Static and dynamic BIT
The T6 Series represent the latest generation of Park Air ATC
radios which are designed for professional applications in airport
and en-route centres. The T6 Series fulfils both analogue (AM)
modulation and the future digital (D8PSK) modes, which are
being planned by ICAO. The T6 Series makes extensive use of
advanced DSP (digital signal processing) technology to enable the
transition from analogue to digital modulation modes to be made
via software upgrade. Investment in radio systems is thereby pro-
tected against obsolescence as new digital modulation waveforms
are introduced.
The T6R operates in the VHF aviation band and provides both
25KHz and 8.33KHz channel spacing. A 100 channel memory is
incorporated for recall of pre-set frequency and operating modes
in multichannel applications.
All demodulation is implemented using DSP algorithms, which
provide consistent long term performance. D8PSK digital modula-
tion waveforms require high performance demodulators to
ensure reliable synchronisation and low BER (bit error rate) at
low signal levels. The T6R employs specially developed algo-
rithms allied to high performance RF circuitry to ensure optimum
performance in this critical area.
Control of receiver operating parameters can be effected locally
using a menu driven front panel LCD or remotely via serial ports
on the rear panel. All receiver adjustments are under software
control and can be accessed externally avoiding any necessity to
remove covers during the operational life of the equipment.
Should software updates be required to support new modulation
modes in the future, these can be simply effected via a front panel
diagnostic 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 novel
technique provides an accurate assessment of receiver sensitivity
using BIT. Results can be viewed on the front panel LCD and are
summarised via READY and ALARM indicators. All BIT data is
available for remote monitoring via the serial ports and receivers
can be readily networked for remote monitoring using PAE
MARC or similar systems.
The receiver is a compact 2U 19” rack mounted unit. Power can
be 110/220 VAC or 24/28 VDC, with automatic switching to DC
in the event of an AC failure. Both inputs are fully filtered and
protected.
