Connecting external devices
Installing USB devices on R&S RTE is easy under the Windows operating system, because all USB devices are plug&play. After a device is connected to the
USB interface, Windows automatically searches for a suitable device driver.
If the operating system does not find a suitable driver, it prompts you to specify a
directory that contains the driver software. If the driver software is on a storage
media, connect the appropriate drive to the instrument before proceeding. If the
instrument is integrated in a network, you can also install driver data stored in a
network directory.
When a USB device is disconnected from the R&S RTE, Windows immediately
detects the change in hardware configuration and deactivates the corresponding
driver.

TRIGGER OUTPUT
The SMA connector for external trigger output is used to provide the internal trigger signal of the oscilloscope to trigger other instruments for synchronized measurements.
When a trigger occurs, the R&S RTE creates a pulse of 5 V with a source impedance of 50 Ω and delivers it to the external trigger output. The instrument can
also send the pulse on mask test violation or violation of measurement limits and
margins.
If the connector is terminated with 50 Ω, the signal level is 2.5 V (50 mA). With
1 MΩ termination, the level is 5 V. A short-circuit of the connector to ground creates current of 100 mA.
To enable the trigger out signal, select "Trigger" menu > "Ctrl/Action". Here you
also adjust polarity, delay, and length of the pulse. The default is a positive pulse
of 100 ns. The minimum delay is 800 ns.

6.1 Displaying a basic signal
Displaying the input from a signal channel is simple and straightforward. Furthermore, you get to know some basic trigger functions. The R&S RTE provides wideranging trigger functions to find various signal anomalies, which are described in
the instrument help and in the "User Manual".
1. Press the [PRESET] key on the front panel (in the [SETUP] area on the left).
2. Connect the probe to the input connector [CH 1].

Connect the probe's ground connector to the right compensation pin , and
the tip to the left pin .
The instrument recognizes the probe, and a signal is displayed in the diagram.
3. Press the [AUTOSET] key on the front panel (in the [SETUP] area on the left).
Autoset finds appropriate horizontal and vertical scales and trigger conditions
to present a stable square waveform. The trigger is set to edge trigger on rising edge with auto trigger mode.

7 Operating the instrument
There are three ways to operate the R&S RTE.
Manual operation
Use the touchscreen, keys and rotary knobs, or an optional mouse and/or keyboard. The principles of manual operation are explained in this section.
Remote control
Create programs to automatize repeating settings, tests, and measurements. The
instrument is connected to a computer that runs the program.
This way of operation is described in the user manual, chapter "Remote Control
Commands".
Remote operation
The remote desktop connection of Windows can be used for instrument control
and file transfer. Even on computers with non-Windows operating systems, a
remote desktop connection is possible using RDP applications.
For details, refer to the user manual, chapter "Remote Desktop Connection".
Remote monitoring and control of the instrument from a connected computer is
also possible with a standard web browser and a LAN connection.
For details, refer to the user manual, chapter "Web Control".
Alternatively, you can use Virtual Network Computing (VNC), which requires
installation of the VNC server on the R&S RTE. Installation and configuration are
described in the application note "Remote Monitoring and Control of the
R&S RTE with a Web Browser", available on the Rohde & Schwarz internet site.
7.1 Means of manual interaction
The R&S RTE provides the following means of manual interaction, which you can
use alternatively or complementary:
●
Touchscreen:
80Getting Started 1326.1026.02 ─ 10
R&S®RTE
Using the touchscreen is the direct interaction way. Use your finger to place
waveforms on the screen, mark areas for zoom and histograms, set parameters in dialog boxes, enter data, and much more. The control elements and
actions on the screen are based on common concepts, and you will easily
become familiar with the user interface.
Tapping the screen works like clicking mouse buttons:
– Tap = click: Selects a parameter or provokes an action.
– Double-tap = double-click has the same effect as touch and hold = right-
click: Opens the on-screen keyboard or keypad, or a specific editor if available
●
Function keys and rotary knobs:
The front panel provides nearly all functions and controls to operate the instrument in the classic ways, without touchscreen. As an exception, the signal bar
cannot be used with front panel controls.
●
Optional mouse and/or keyboard:
These devices work conform to Windows standards. The navigation keys on
the front panel correspond to the keys on the keyboard.

By default, the diagram name contains the diagram number and the short names
of the waveforms shown inside. To change the diagram name, touch and hold the
tab name. The on-screen keyboard opens to enter the new name. Names must
be unique.
To arrange the diagrams on the screen, the Rohde & Schwarz SmartGrid function
helps you to find the target place simply and quickly. For details, see Chapter 7.5,
"Rohde & Schwarz smartgrid", on page 91. You can also adjust the diagram size
by dragging the diagram border.
Grid (2)
The grid shows the vertical and horizontal divisions. The division lines are labeled
with the correspondent values. The grid labels have the color of the waveform to
which they belong. If several waveforms are shown in one diagram, the grid has
the color of the selected waveform.
Signal bar (3)
The signal bar is the control center for all enabled waveforms. On the top, the
horizontal and trigger labels show the main timebase and trigger settings. If you
tap a label, the relevant dialog box opens with the tab used at last.

Trigger position and trigger level (4, 5)
The blue markers show the horizontal position of the trigger and the vertical trigger level. You can touch and move the trigger markers in the diagram to set the
positions. The trigger point is the zero point of the diagram.
The trigger position can be moved outside the diagram. A red trigger position
marker indicates that the trigger position is not visible.
Reference point (6)
The reference point marks the rescaling center. If you modify the time scale, the
reference point remains fixed on the screen, and the scale is stretched or compressed to both sides of the reference point.
You can define the position of the reference point (HORIZONTAL), and its time
distance from the trigger point of the diagram (POSITION / REF POINT).

Zoom diagram and zoom area (7, 8)
Zoomed waveforms are shown in separate zoom diagrams, in addition to the
waveform diagrams. On the original waveform diagram, a rectangle indicates the
zoomed section of the waveform - this is the zoom area. You can modify the
zoom area by dragging the rectangle as a whole, and by dragging its edges. To
toggle between these modes, tap the zoom area. You can also set exact positions.
The frames of the zoom area and of the associated zoom diagram have the same
color, different zooms are marked with different colors. So it is easy to assign
zoom area and zoom diagram.
As for waveform diagrams, you can change the name of the zoom diagram. A
zoom in a zoom and coupled zooms are also possible.
All zooming possibilities are described in detail in the User Manual, chapter
"Zoom".

in two logic probes (pods) with 8 channels each.
88Getting Started 1326.1026.02 ─ 10
R&S®RTE
Waveform handling
The R&S RTE can show and analyze many waveforms. To handle this multitude
while keeping track of it, the R&S RTE provides intelligent support:
●
The color system helps to distinguish the waveforms. The color of the vertical
rotary knobs indicates the signal that is focused (selected). The color of each
waveform can be changed, the color of its signal icon and of the illuminated
keys is adjusted to the new color. Alternatively, a color table can be assigned
to a waveform.
Settings: [DISPLAY] > "Signal Colors / Persistence" tab.
●
Waveforms can be minimized to signal icons showing a small real-time signal
view. Thus, more space in the diagram area is available without switching off
waveforms.
●
Diagrams are displayed on tabs – you can arrange them side by side or one
above the other. To change the diagram name, double-tap the tab name.
Operating the instrument
Working with waveforms
●
The Rohde & Schwarz SmartGrid function helps to arrange the diagrams.
Waveform states
Depending on its place on the screen and the effect of settings, a waveform has
one of the following states:
●
Off
●
Active:
The waveform is shown in a diagram
●
Selected:
One of the active waveforms that has the focus. In each diagram, one of the
assigned waveforms is selected – it appears "on top" in the diagram, and the
grid labels have the color of the selected waveform. Some of the toolbar functions, like cursor and histogram measurements are performed on the selected
waveform. All waveform-specific settings are applied to the selected waveform
of the selected diagram.
The vertical [POSITION / OFFSET] and the [SCALE] knobs are illuminated
with the color of the selected waveform.
In Figure 7-1, "Ch1" is the selected waveform: The frame of the diagram and
the signal icon are highlighted.
●
Minimized:
