4 R&S TMU9 - Main benefits Efficient Up to 42%, highest power efficiency on the market Powerfu Output power that meets your TPO requirements Affordabe Top-edge technoogy transmitter at a price you can afford Aways on the Air Redundancy is the key in the TMU9 design for a reiabe transmitter 25 June 2013 TMU9 4

5 R&S TMU9 - Main components Main system components R&S TCE900 Exciter R&S PMU901 - Ampifier R&S TCE900 R&S TDU900 Power Combiner Power Combiner R&S ZR900Z10 - Main Distribution R&S PMU901 R&S TDU900 (optiona) Touch Dispay R&S ZR900Z10 25 June 2013 TMU9 5

6 R&S TCE900 Exciter R&S TCE900 incorporates Exciter and System Contro unit Standard adaptive digita equaization Remote contro, secure web browser, SNMP monitoring SMPTE310, ASI and IP inputs ATSC Mobie DTV (A/153) ready [Option] A/110b SFN ready [Option] Interna GPS reference [Option] Less Spare parts: Usage of one base unit for exciter and contro Less maintenance 25 June 2013 TMU9 6

7 R&S PMU901 Ampifier Efficient Ampifier Layout Power density of 570 W per ampifier 6 fina stage transistors Redundant Fans 1 singe phase power suppy 3 kw, passivy cooed Dust fiter 2nd power suppy for 1+1 redundancy (option) Enhanced efficiency mode Doherty (option) 25 June 2013 TMU9 7

8 Smart Doherty ampifier technoogy Ampifier consists of a base unit and one Tunit The base unit is aways broadband The Tunit defines operation mode: Norma mode Ave. 25% efficiency Doherty mode Ave. 40% efficiency, band seective Each Tunit can be used in norma mode in case of channe change 25 June 2013 TMU9 8

9 How Much Money Can You $ave? An exampe: Transmitter output power: 2 kw Lifetime of transmitter: 15 years Assumed energy cost: $0.10 /kwh Average transmitter R&S TMU9 with Doherty option Efficiency 20% 40% Energy costs $131,400 $65,700 Energy cost savings over 15 years: $65,700 Energy cost savings per year: ~$4, June 2013 TMU9 9

10 1:1 Power Suppy Redundancy AC in PSU 1 Haf Fu Power PSU 2 Haf Power Driver stage/fina stage/acb/fans/ Fu 1:1 power suppy redundancy, no power drop in case of PSU faiure Hot puggabe Low maintenance costs due to higher MTBF 25 June 2013 TMU9 10

11 Power Combiner Integrated 6 in 1 concept: 1. Couping unit 2. Input spitter 3. Harmonic Fiter (frequency band seective) 4. Lightning protection 5. Measuring coupers 6. Absorbing resistor Low oss through integration of harmonic fiter and combiner in one device 25 June 2013 TMU9 11

12 Mains Distribution Boards 240V L1/L2/PE, grounded midpoint Space savings through compact ayout, ony 4 rack units High avaiabiity through Over-votage protection Monitoring of the over-votage avaiabe [option] Each unit in the rack has its own fuse 25 June 2013 TMU9 12

13 Option Exhaust Air Kit Exhaust air kit for guided air-out Mounted instead of rear door Pressure controed Two fans Temperature monitoring Air ducting adaptation to station ducting R&S TMU9, 3 x 1.14 kw, ducted air 25 June 2013 TMU9 13

14 Loca and Remote Contro Loca Contro via IP port Remote Contro via IP connectivity Loca Contro via TDU900 Touch screen Dispay Unit [Option] Retractabe to save space Remote contro via SNMP agent using your existing NMS [Option] Remote Contro via R&S BC- NETSTATE [Option with additiona software.
