Risk of injury when stacking instruments
A stack of instruments can tilt over and cause injury if not stacked correctly. Further-
more, the instruments at the bottom of the stack can be damaged due to the load
imposed by the instruments on top.
Observe the following instructions when stacking instruments:
●Never stack more than three instruments. If you need to stack more than three
instruments, install them in a rack.
●The overall load imposed on the lowest instrument must not exceed 500 N.
●It is best if all instruments have the same dimensions (width and length).
If you need to stack smaller instruments on the top, the overall load imposed on the
lowest instrument must not exceed 250 N.
●If the instruments have foldable feet, fold them in completely.
2.2.2 Rackmounting
The instrument can be installed in a rack using a rack adapter kit. The order number is
given in the data sheet. The installation instructions are part of the adapter kit.
Risk of instrument damage due to insufficient airflow in a rack
If you mount several instruments in a rack, you need an efficient ventilation concept to
ensure that the instruments do not overheat. Insufficient airflow for a longer period can
disturb the operation and even cause damage.

Risk of injury
Connect the oscilloscope to an outlet that has a ground contact.
If grounding is not ensured by the mains system, ground the oscilloscope using the
protective earth conductor on the front panel and an appropriate cable.
Do not use an isolating transformer to connect the oscilloscope to the AC power sup-
ply.
2.3.1 Powering On and Off
The R&S RTO can be used with different AC power voltages and adapts itself automat-
ically to it.
The nominal ranges are:
●100 V to 240 V AC at 50 Hz to 60 Hz and 400 Hz
●max. 5.5 A to 2.3 A
●max. 450 W
To power on
1. Connect the power cable to the AC power connector on the rear panel of the
R&S RTO.
2. Connect the power cable to the socket outlet.
3. Switch the main power switch at the rear of the instrument to position I.
The power key on the front panel lights up.
Before you start measurements, be sure to comply with the warm-up phase specified
in the data sheet.
If you leave the main power switch on, the instrument is in standby mode. To discon-
nect from power supply, power off the instrument. Powering off is only required if the
instrument must be disconnected from all power supplies.
To power off
1. If the instrument is running and the [Power] key is green, press the [Power] key on
the front panel to shut down the instrument.

R&S®RTO2000
15Getting Started 1332.9719.02 ─ 08
Risk of losing data
If you switch off the running instrument using the rear panel switch or by disconnecting
the power cord, the instrument loses its current settings. Furthermore, program data
can be lost.
Press the POWER key first to shut down the application properly.
Powering off also interrupts the power supply of the OCXO (option OCXO Reference
Frequency, R&S RTO-B4).
2.3.2 Starting Up and Shutting Down
The [Power] key is located in the bottom left corner of the front panel.
To start up the instrument
1. Make sure that the R&S RTO is connected to the AC power supply and the main
power switch on the rear panel is in position I.
2. Press the [Power] key on the front panel.
The instrument performs a system check, boots the Windows operating system,
and then starts the R&S RTO firmware.
The [Power] key turns green and the illuminated keys on the front panel light up. If
the previous session was terminated regularly, the oscilloscope uses the last set-
tings.
To shut down the instrument
► Press the [Power] key on the front panel.
All current settings are saved, and the software shuts down. The standby power
only supplies the power switch circuits and the optional oven quartz (OCXO, option
R&S RTO-B4).
Now it is safe to power off the instrument.
The "Exit" function in the "File" menu shuts down only the firmware application. To shut
down the instrument completely, also shut down the operating system in the "Start"
menu, or use the [Power] key.
2.3.3 EMI Suppression
Electromagnetic Interference (EMI) may affect the measurement results.
To suppress generated Electromagnetic Interference:
●Use suitable shielded cables of high quality. For example use double-shielded RF
and LAN cables.
Starting the Instrument

Preparing for Use
R&S®RTO2000

●Connecting USB Devices........................................................................................16
●Connecting an External Monitor..............................................................................17
2.4.1 Connecting USB Devices
The USB interfaces on the front and rear panels allow you to connect USB devices
directly to the instrument. The number of USB connectors can be increased by using
USB hubs. Due to the large number of available USB devices, there is almost no limit
to the expansions that are possible with the R&S RTO.
The following USB devices can be useful, for example:
●USB flash drives to save screenshots and measurement results, and for easy
installation of firmware applications
●Keyboard and/or mouse to simplify the operation and the entry of data, comments,
filenames, etc.
●Printer to print measurement results and screenshots
You can connect or disconnect all USB devices during operation of the instrument.
Installing USB devices on R&S RTO is easy under the Windows operating system,
because all USB devices are plug&play. After a device is connected to the USB inter-
face, Windows automatically searches for a suitable device driver.
If the operating system does not find a suitable driver, it prompts you to specify a direc-
tory that contains the driver software. If the driver software is on a storage media, con-
nect the appropriate drive to the instrument before proceeding. If the instrument is inte-
grated in a network, you can also install driver data stored in a network directory.
When a USB device is disconnected from the R&S RTO, Windows immediately detects
the change in hardware configuration and deactivates the corresponding driver.
The properties of external USB devices are configured in the operating system, not in
the R&S RTO software. It is recommended that you use mouse and keyboard to
access and modify the settings of the Windows operating system. To access Windows,
press the Windows key on the external keyboard, or select "File" > "Minimize Applica-
tion" on the R&S RTO menu.

Instrument damage caused by cleaning agents
Cleaning agents contain substances such as solvents (thinners, acetone, etc.), acids,
bases, or other substances. Solvents can damage the front panel labeling, plastic
parts, or screens, for example.
Never use cleaning agents to clean the outside of the instrument. Use a soft, dry, lint-
free dust cloth instead.
3.1.1 Input Connectors
The R&S RTO has two or four channel inputs to connect the input signals using active
and passive probes.
The input connectors are provided with a special Rohde & Schwarz active probe inter-
face, and they are BNC compatible. Thus, the instrument can automatically detect pas-
sive probes with standard BNC connector and active Rohde & Schwarz probes having
the Rohde & Schwarz probe interface.
The input impedance is selectable, the values are 50 Ω and 1 MΩ.
Risk of electrical shock or fire
Voltages higher than 30 V RMS or 42 V peak or 60 V DC are regarded as hazardous
contact voltages. When working with hazardous contact voltages, use appropriate pro-
tective measures to preclude direct contact with the measurement setup:
●Use only insulated voltage probes, test leads and adapters.
●Do not touch voltages higher than 30 V RMS or 42 V peak or 60 V DC.
