Product overheating can cause electric shock, fire and/or serious personal injury or even death.

Electrical safety

If the information on electrical safety is not observed either at all or to the extent necessary, electric shock, fire and/or serious personal injury or death may occur.

1. Prior to switching on the product, always ensure that the nominal voltage setting on the product matches the nominal voltage of the AC supply network. If a different voltage is to be set, the power fuse of the product may have to be changed accordingly.

2. In the case of products of safety class I with movable power cord and connector, operation is permitted only on sockets with a protective conductor contact and protective conductor.

3. Intentionally breaking the protective conductor either in the feed line or in the product itself is not permitted. Doing so can result in the danger of an electric shock from the product. If extension cords or connector strips are implemented, they must be checked on a regular basis to ensure that they are safe to use.

4. If there is no power switch for disconnecting the product from the AC supply network, or if the power switch is not suitable for this purpose, use the plug of the connecting cable to disconnect the product from the AC supply network. In such cases, always ensure that the power plug is easily reachable and accessible at all times. For example, if the power plug is the disconnecting device, the length of the connecting cable must not exceed 3 m. Functional or electronic switches are not suitable for providing disconnection from the AC supply network. If products without power switches are integrated into racks or systems, the disconnecting device must be provided at the system level.

5. Never use the product if the power cable is damaged. Check the power cables on a regular basis to ensure that they are in proper operating condition. By taking appropriate safety measures and carefully laying the power cable, ensure that the cable cannot be damaged and that no one can be hurt by, for example, tripping over the cable or suffering an electric shock.

asic Safety Instructions

6. The product may be operated only from TN/TT supply networks fuse-protected with max. 16 A (higher fuse only after consulting with the Rohde & Schwarz group of companies).

7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the socket provided for this purpose. Otherwise, sparks that result in fire and/or injuries may occur.

8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric

hocks.

9. For measurements in circuits with voltages V

> 30 V, suitable measures (e.g. appropriate

rms

measuring equipment, fuse protection, current limiting, electrical separation, insulation) should be taken to avoid any hazards.

10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial computers, comply with the IEC60950-1/EN60950-1 or IEC61010-1/EN 61010-1 standards that apply in each case.

11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the product.

12. If a product is to be permanently installed, the connection between the protective conductor terminal on site and the product's protective conductor must be made first before any other connection is made. The product may be installed and connected only by a licensed electrician.

13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective devices, the supply circuit must be fuse-protected in such a way that anyone who has access to the product, as well as the product itself, is adequately protected from injury or damage.

14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the product. Otherwise, the person operating the product will be exposed to the danger of an electric shock.

15. Any object that is not designed to be placed in the openings of the housing must not be used for this purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries.

16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and operating positions", item 1). Therefore, the equipment must be protected against penetration by liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product itself may be damaged, which can also lead to personal injury.

17. Never use the product under conditions in which condensation has formed or can form in or on the product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water increases the risk of electric shock.

18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such as alcohol, acetone or diluents for cellulose lacquers.

Operation

1. Operating the products requires special training and intense concentration. Make sure that persons who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries or material damage may occur. It is the responsibility of the employer/operator to select suitable personnel for operating the products.

To set the number of acquisitions, press the ACQUISITION key and enter "Nx Single".

FORCE

If the acquisition is running in normal mode and no valid trigger occurs, forcing the trigger provokes an immediate single acquisition. Thus you can confirm that a signal is available and use the waveform display to determine how to trigger on it.

MODE

Toggles the trigger mode between Auto and Normal. The trigger mode determines the behaviour of the instrument if no trigger occurs. The current setting is shown in the information bar.

LEVEL

The rotary knob changes the trigger treshold voltage for all trigger types that require a trigger level.

Turn clockwise to move the trigger level up. At zero-crossing, the knob shortly snaps in and the setting is kept constant to simplify the zero-setting. Press the knob to set the level to 50% of the signal amplitude.

R&S®RTM

Instrument Setup

Adjusting Passive Probes

Recommendation on performing the self-alignment:

when putting the instrument into operation for the first time

●

once a week

●

when major temperature changes occur (> 5°)

●

Warm-up the instrument

Make sure that the instrument has been running and warming up before you start the self-alignment. The minimum warm-up time is indicated in the data sheet.

1. Remove all signal lines from the channel and external inputs.

2. Press SETUP > "Self Alignment".

3. Press "Start" to start the internal alignment.

6.3 Adjusting Passive Probes

R&S RTM-ZP10 passive probes are already pre-compensated to the R&S RTM frontend characteristcs, and a compensation procedure is not required.

If you use other passive probes, the R&S RTM allows you to compensate it when it is connected to the instrument the first time. Compensation matches the probe cable capacitance to the oscilloscope input capacitance to assure good amplitude accuracy from DC to upper bandwidth limit frequencies. A poorly compensated probe reduces the performance of the probe-oscilloscope system and introduces measurement errors resulting in distorted waveforms and inaccurate results.

Two connector pins are located on the front panel. The right pin is on ground level. The left pin supplies a square wave signal for the adjustment. You can choose between two frequencies for usual low frequency compensation and additional high frequency compensation. The rise time does not differ between the settings.

1. Connect the BNC connector of the probe to input CH1.

2. Connect the probe's ground connector to the right compensation pin, and the tip with the left pin.

3. Select SETUP > "Probe Adjust".

4. Select the frequency for the adjustment signal by pressing the corresponding softkey. The following frequencies are available:

● 1kHz: A square wave with a frequency of f = 1 kHz is generated at the probe

compensation pin. Use this setting to adjust the LF band of the probe.

● 1MHz: A square wave with a frequency of f = 1 MHz is generated at the probe

compensation pin. Use this setting to adjust the HF band of the probe.

R&S®RTM

Instrument Setup

Adjusting Passive Probes

● Automatic: A square wave is generated at the probe compensation pin. The

frequency of the square wave depends on the defined time base. If the time base becomes too small to display the 1 kHz wave, it is automatically switched to a 1 MHz wave. It is recommended that you do not use this setting for probe compensation.

5. Press AUTOSET.

A square wave appears on the display.

6. Adjust the compensation trimmer of the probe to optimum square wave response. For details, refer to the documentation of your probe.

Maintenance

Cleaning

7 Maintenance

The instrument does not need a periodic maintenance. Only the cleaning of the instrument is essential.

To protect the front panel and to transport the instrument to another workplace safely and easily, two accessories are provided:

● Soft case (R&S RTM-Z3, order number 1305.0289.02)

● Front cover (R&S RTM-Z1, order number 1305.0272.02)

Follow the instructions in the service manual and the safety instructions when exchanging modules or ordering spares. The order no. for spare parts is included in the service manual. The service manual includes further information particularly on troubleshooting, repair, exchange of modules and alignment.

The addresses of Rohde & Schwarz support centers can be found at http://www.cus-

tomersupport.rohde-schwarz.com. A list of all service centers is available via http:// www.services.rohde-schwarz.com.

7.1 Cleaning

The outside of the instrument can be cleaned sufficiently using a soft, lint-free dust cloth. Make sure that the fan openings are not obstructed.

Shock hazard

Before cleaning the instrument, make sure that the instrument is switched off and disconnected from all power supplies.

Instrument damage caused by cleaning agents

Cleaning agents contain substances that may damage the instrument, e.g. cleaning agents that contain a solvent may damage the front panel labeling or plastic parts.

Maintenance

Storing and Packing

Risk of instrument damage due to obstructed fans

If the instrument is operated in dusty areas, the fans may become obstructed by dust or other particles in the process of time. Make sure to check and, if necessary, clean the fans regularly to ensure they operate properly at all times. If the instrument is run with obstructed fans for a longer period, it may become overheated which may cause damage.

7.2 Storing and Packing

The storage temperature range of the instrument is given in the data sheet. If the instrument is to be stored for a longer period of time, it must be protected against dust.

Repack the instrument as it was originally packed when transporting or shipping. The two protective foam plastic parts prevent the control elements and connectors from being damaged. The antistatic packing foil avoids any undesired electrostatic charging to occur.

If you do not use the original packaging, use a sturdy cardboard box of suitable size and provide for sufficient padding to prevent the instrument from slipping inside the package. Wrap antistatic packing foil around the instrument to protect it from electrostatic charging.

7.3 Replacing the Fuses

The instrument is protected by a two fuses, located on the rear panel between the main power switch and AC power supply.

Type of fuses: Size 5x20 mm, 250 V~, T 2 A (slow-blow), IEC 127 Bl. III

Shock hazard

Before replacing a fuse, make sure that the instrument is switched off and disconnected from all power supplies.

Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of the same type and rating.

1. Pull the fuse holder out of its slot on the rear panel.

2. Exchange the two fuses.

3. Insert the fuse holder carefully back in its slot until it is latched.
