Chapter 1 Safety Instructions Safety Instructions for Transmitter Systems and Instruments ATTENTION! The safety instructions provided in this manual must be complied with! Pay special attention to the following points:  Only skilled personnel may perform electrical installation and electrical connection tasks.
Page 21: General Safety Instructions
Chapter 1 Safety Instructions General Safety Instructions This section contains general safety instructions that apply to all products manufactured or distributed by Rohde & Schwarz. In accordance with IEC 215 and EN 60215, transmitters and their auxiliary equipment must be operated only under the responsibility of skilled personnel. The EN 60215 standard ("Safety requirements for radio transmitting equipment") defines the minimum requirements for skilled electrical personnel.
Page 22: Special Danger Warnings
Chapter 1 Safety Instructions Special Danger Warnings Hazards due to AC Supply Voltage There is a risk of electric shock with any V > 30 V AC or V > 60 V DC voltage. Appropri- ate measures must be taken to prevent exposure to any danger when working with voltages that bear the risk of electric shock.
Page 23: Rf Hazards
Chapter 1 Safety Instructions  If you need to measure low-impedance voltages, during repair work for example, exer- cise the same caution as when measuring operating voltages that bear the risk of elec- tric shock. Wear protective clothing if necessary. ...

Antes de la puesta en marcha del producto se deberá comprobar siempre que la tensión preseleccionada en el producto coincida con la de la red de alimentación eléctrica.
Page 34 Informaciones elementales de seguridad 12. Si un producto se instala en un lugar fijo, se deberá primero conectar el conductor de protección fijo con el conductor de protección del producto antes de hacer cualquier otra conexión. La instalación y la conexión deberán ser efectuadas por un electricista especializado. 13.
Page 35 Informaciones elementales de seguridad 5. Ciertos productos, como p. ej. las instalaciones de radiocomunicación RF, pueden a causa de su función natural, emitir una radiación electromagnética aumentada. Deben tomarse todas las medidas necesarias para la protección de las mujeres embarazadas. También las personas con marcapasos pueden correr peligro a causa de la radiación electromagnética.

Chapter 5 Operating 1.5.1.3 Testing SNMP Communications SNMP communications is properly set up if you have loaded the MIBs in your program and you are using the correct IP address of the transmitter and the correct community. For que- ries and settings you must set the SNMP version in your manager; the transmitters detect the used protocol automatically.

Chapter 5 Operating Introduction to Manual Precorrection Factory set precorrection curves v. manual precorrection The transmitter equipment includes factory preset precorrection curves covering every fre- quency range and all dynamic ranges. The appropriate precorrection curve is automatically loaded in each case, so as a rule manual precorrection is not needed. In certain cases the precorrection can be further optimized by manual precorrection.

Page 147 Chapter 5 Operating Fig. 16 Basic structure of an operating field Each operating field consists of graphics areas and functional areas. The graphics areas are used to display the set characteristics. Here, you can interactively modify, reset or redraw the characteristics. You can also set a default characteristic. Using a contextual menu, you can access additional functions as well as a navigator for fine ad- justment.
Page 148: Graphic Areas
Chapter 5 Operating 5.2.2 Graphic Areas The graphics area basically consists of display and drawing levels. In many operating fields, the drawing level is not necessary. Display level (blue characteristic) In the display level, the characteristic that is currently set in the precorrector is displayed. If the precorrector function is switched off, a note to this effect will appear in the diagram.
Page 149 Chapter 5 Operating Fig. 17 Contextual menu for the precorrector GUI The contextual menu appears if you click on a vacant point of the drawing plane with the right mouse button. You can use the contextual menu to call up the navigator window for making fine settings.
Page 150 Chapter 5 Operating 3. Point to the right margin of the diagram with the mouse and set the last point. Input mode will be terminated and you can now edit the curve as required (see the sec- tion "Editing the characteristic"). Loading an existing characteristic curve Instead of creating a characteristic curve from scratch, you can load existing curves into the drawing level and edit them as required.

Chapter 5 Operating Graphics area 2: Modeling of the group delay The Linear Groupdelay diagram (in graphics area 2) has a coordinate system for display- ing and editing the characteristic for the amplitude frequency response. The x axis is used to display the frequency f in MHz relative to the carrier or to the center frequency.

Chapter 5 Operating Fig. 20 The Nonlinear operating window 5.4.1 Main Function The Corr > On/Off switch can be used to turn the entire nonlinear precorrection on or off. 5.4.2 Nonlinear Precorrection For manual precorrection, you model the amplitude and phase characteristics in the draw- ing level and then write them to the precorrection memory.
