Safety Instructions R&S® TMU9 Safety Instructions for Transmitter Systems and Equipment 2 Safety Instructions 2.1 Safety Instructions for Transmitter Systems and Equipment Compliance with safety regulations The safety regulations specified in this manual must always be complied with. The following points require special attention: ● Only qualified technicians are allowed to install and wire the electrical equipment.
Safety Instructions R&S® TMU9 General Safety Instructions on working with hazardous products (coolant) must be observed; see the section "Material Safety Data Sheets" under "EC Safety Data Sheet – Antifrogen". 2.2 General Safety Instructions This section contains general safety instructions applying to all products manufactured or sold by Rohde & Schwarz.
Safety Instructions R&S® TMU9 General Safety Instructions tions). Use of the product requires specialist knowledge and, in part, knowledge of the English language. It is therefore important to ensure that the product is operated only by specialist personnel and persons with the appropriate skills who have received detailed instruction in how to operate the product.
Safety Instructions R&S® TMU9 General Safety Instructions with non-associated products or non-associated documentation can lead to incorrect interpretation and thus result in injury and damage. Operating conditions, positions and locations The product should only be operated in the operating conditions, positions and locations specified by the manufacturer such that ventilation is not obstructed.
Safety Instructions R&S® TMU9 General Safety Instructions 3. Any deliberate interruption of the PE conductor (both along the feed line and at the product itself) is not permitted. This can result in a potential shock hazard at the product. If extension cables or multipoint connectors are used, it must be ensured that their safety is checked at regular intervals. 4.
Safety Instructions R&S® TMU9 General Safety Instructions 14. Every product must be protected against overvoltage (e.g. as a result of a lightning strike) by means of appropriate overvoltage protection. The operating personnel are otherwise at risk of electric shock. 15. Foreign objects must not be inserted into the openings of the housing. This can cause short circuits in the product and/or electric shocks, fire or injury. 16.
Safety Instructions R&S® TMU9 General Safety Instructions 6. In the event of fire, toxic substances (gases, fluids, etc.) can be discharged from the product and damage the health of personnel. If a fire occurs, appropriate measures must therefore be taken (e.g. breathing masks and protective clothing). 7. If a laser product is integrated in an Rohde & Schwarz product (e.g.

Cells or batteries must be recycled and must not be disposed of with residual waste. Rechargeable batteries or batteries containing lead, mercury or cadmium must be disposed of as special waste. Observe the country‑specific disposal and recycling regulations. Transport 1. The product can be extremely heavy.
Safety Instructions R&S® TMU9 Special Hazard Information 2.3 Special Hazard Information 2.3.1 Hazards from AC Supply Voltage All voltages of Urms > 30 V AC or U > 60 V DC must be regarded as constituting a shock hazard. When working with voltages that constitute a shock hazard, appropriate measures must be taken to prevent exposure to danger. Never work on live components. Work on live parts should only be performed in exceptional cases and only if special safety precautions are taken. 2.3.1.1 2.3.1.
Safety Instructions R&S® TMU9 Special Hazard Information ● Before opening any equipment or removing a particular cover, turn off the power supply and wait 5 minutes to ensure that capacitors have discharged sufficiently. ● Do not discharge capacitors by short‑circuiting them. 2.3.3 Hazards from RF Radiation 2.3.3.1 Obligation to Instruct Personnel ● The operator must train all personnel in the operation of this transmitter or instrument in line with EN60215 and/or IEC215.

Transmitter System R&S TMU9 R&S® TMU9 Design and Function R&S TMU9 3 Transmitter System R&S TMU9 3.1 Design and Function R&S TMU9 The TV transmitters of the R&S TMU9 transmitter family support the following standards. With DTV operation: ● DVB-T/H ● DVB‑T2 ● ATSC/ATSC Mobile ● ISDBTB This manual describes the TV transmitters of the R&S TMU9 transmitter family, which support the DVB-T/H, DVB-T2, ATSC and ISDBTB standards. 3.1.
Transmitter System R&S TMU9 R&S® TMU9 Design and Function R&S TMU9 In the following, different examples of transmitters with maximum configuration are displayed. Fig. 3-1: TMU 9 – Multi Tx single drive with six transmitters. System Manual 2600.5423.
Transmitter System R&S TMU9 R&S® TMU9 Design and Function R&S TMU9 Fig. 3-2: TMU9 – Multi Tx dual drive with five transmitters. 3.1.3 Redundancy Concepts Single transmitter (single drive) This simplest variant for medium-power transmitters consists of an exciter (R&S TCE900Exciter) and an output stage. The redundancy in this transmitter type is exclusively in the output stage, which can consist of n amplifiers (n = max. of 5 per rack). System Manual 2600.5423.
Transmitter System R&S TMU9 R&S® TMU9 Design and Function R&S TMU9 Fig. 3-3: Single Drive - block diagram. Dual drive This variant of a dual-drive transmitter consists of a transmitter control unit (R&S TCE900SystemControl), two exciters (R&S TCE900 exciter), an exciter switch, and an output stage. If one of the exciters fails, the transmitter control unit uses the exciter switch automatic to switch to the second exciter via moving the exciter switch.
Transmitter System R&S TMU9 R&S® TMU9 Design and Function R&S TMU9 Fig. 3-4: Dual Drive - block diagram Backup drive This variant of a dual-drive transmitter consists of 2 exciters (R&S TCE900 exciter) with various functions, an exciter switch, and an output stage. In contrast to the dual-drive solution, with the backup drive a TCE900-System Control is not necessary. By default, the program exciter (R&S TCE900 program exciter) is connected to the output stage and supplies the modulation signal.
Transmitter System R&S TMU9 R&S® TMU9 Design and Function R&S TMU9 Fig. 3-5: Backup drive – block diagram. 3.1.4 Applications MultiTx transmitters can be combined with any kind of redundancy. Consequently, however, the possible maximum number of transmitters in a rack decreases.
Transmitter System R&S TMU9 R&S® TMU9 Design and Function R&S TMU9 Up to 6 single transmitters can be integrated for each rack. Up to 5 dual drives can be installed for each rack. MultiTx transmitters each with 2 amplifiers / Tx Up to 3 single transmitters can be integrated for each rack. Up to 3 dual drives can be installed for each rack. Fig. 3-6: MultiTx transmitters, each with 2 amplifiers per transmitter.

X203B Messages 19 to 24 and 78 are applied to X203A. Messages 28 to 33 and 79 are applied to X203B. NO contacts are available for message 19 to 24 and 28 to 33; all others have DT contacts.
Transmitter System R&S TMU9 R&S® TMU9 Design and Function R&S TMU9 The designation of the connector pin indicates the respective half of the tandem connector. Example: Command 1 is applied to connector X101, pin 1A. The command can be input at connector pin 1 of connector 101A. Command Inputs All command inputs are operated via optocouplers with a floating supply voltage that is generated on the module. A command input becomes active by means of a connection to the common command line.
Transmitter System R&S TMU9 R&S® TMU9 Design and Function R&S TMU9 Single Transmitter and Standby System In a single transmitter, the remote control interface is directly connected to the TCE900 SysCtrl via the CAN bus plug X1. The X11 socket remains free. In standby systems, the CAN bus is connected to further n+1 modules via X11. 3.1.5.
