4T2-Rack
The 4T2-Rack transmitter monitoring instrument is the latest generation of terrestrial DVB measurement systems, combining comprehensive real-time monitoring of RF-parameters, and of up to two transport stream sources at the same time.
The system utilises ABC's unique hybrid demodulator technology, resulting in better than 40dB MER values without the need for calibration.
Level, and frequency readings, constellation, CCDF, Impulse Response, and Spectrum displays are processed by the 4T2 RF-Analyser application.
The MPEG-2 Transport Stream is demodulated by a state-of-the-art demodulator chip-set. Base-band information is streamed into the system main memory and converted to IP-data using the XTASI hardware-module and software server-application.
The 4T2-Rack has the capability to run two 4T2 Content-Analyser instances in parallel to simultaneously monitor the MPEG transport stream fed into the transmitter, and the one demodulated from the RF output.
Remote Control is achieved by implementing the DVB-SNMP interface to ensure seamless operation with third party network management software. The instruments are prepared to be integrated into a network with a Gbit-ethernet interface. Relay contacts are available for local alarming.
Comprehensive alarm and warning logs are available. The system is highly configurable and can be adjusted to be kept up to date to meet future measurement, and monitoring requirements.
