Rohde & Schwarz has introduced a new UHF medium-power transmitter with an output power from 400 W to 600 W. The R&S TMU9compact allows broadcast network operators to reduce operating costs drastically. It supports the DVB-T2, DVB-T, ISDB-TB and ATSC digital TV standards, making it compatible with networks around the globe.
The R&S TMU9compact provides extensive functionality in compact package. This has been achieved through numerous innovations and R&S's consistent focus on the features essential for broadcasting. The transmitter offers outstanding efficiency, reliability and signal quality. It is scalable and can adapt to a variety of requirements. For example, it can be operated as a single transmitter containing only an exciter and an amplifier, or it can be configured as a well-equipped transmitter system including system control, rack, GPS infrastructure, exhaust air kit and other components.
The unique Multiband Doherty technology, developed by R&S has been integrated in this device. It is through this technology that the medium-power transmitter is able to achieve an energy efficiency of up to 35 percent. This increase in efficiency results in a 50% reduction of energy costs when compared with other transmitters in its class.
Professional TV networks benefit from maximized on-air time. They makes this possible primarily through their high product quality, through options such as the integrated exciter backup battery, and innovative redundancy concepts. The R&S TMU9compact transmitter offers the highest availability and reliability in its class.
It can be easily integrated into a variety of setups with the option of operating it as a desktop transmitter or one that is integrated into a 19" rack. There are only a few requirement that exist with respect to the surrounding setup, which further minimizes infrastructure costs. As a single-drive transmitter with integrated DVB-S/S2 signal feed, it requires minimal space, i.e. 3 units for 400 W and 4.5 units for 600 W output power. Heat dissipation is kept to a minimum.
The R&S TMU9compact minimizes service effort. Errors occur only rarely due to the transmitter’s high reliability. The transmitter is nevertheless well equipped to handle errors that do occur. Its intelligent fault diagnostics can be remotely initiated, and faults are efficiently eliminated. The transmitter can be brought back on air quickly and easily. Its modular design makes it possible for customers to replace and repair most components on their own. It uses adaptive precorrection (ADE) to achieve optimal signal quality and efficiency for the set output power and frequency. Another attractive feature: the currently set Doherty band is always visible on the amplifier display, even if no power is applied. Therefore, if a replacement amplifier is needed, it does not have to be switched on, nor does its housing need to be opened.
This medium-power transmitter with output power from 400 W to 600 W is now available in single and backup-drive configurations as well as in passive standby and N+1 configurations. It enhances the R&S Tx9 transmitter generation and is optimized to cover the power range between low-power transmitters and rack-based medium-power transmitters. Like all other transmitters from the R&S Tx9 generation, it can be delivered at short notice, even if ordered in large quantities.
