BNC inputs (6, 7)
The R&S RTC1000 has two channel inputs (6) to connect the input signals. The exter­nal trigger input (7) is used to control the measurement by an external signal. The trig­ger level can be set from -5 V to 5 V.
The input impedance of all BNC inputs is 1 MΩ.
Risk of electrical shock - maximum input voltages
The maximum input voltage on channel inputs must not exceed 200 V (peak) and 150 V (RMS).
For the external trigger input, the maximum input voltage is 100 V (peak) and 70 V (RMS).
Transient overvoltages must not exceed 200 V (peak).
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 protective 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.
Risk of injury and instrument damage
The instrument is not rated for any measurement category. When measuring in circuits with transient overvoltages of category II, III or IV circuits, make sure that no such overvoltages reach the R&S RTC1000 input. Therefore, use only probes that comply with DIN EN 61010-031. When measuring in category II, III or IV circuits, always insert a probe that appropriately reduces the voltage so that no transient overvoltages higher than 200 V (peak) are applied to the instrument. For detailed information, refer to the documentation and safety information of the probe manufacturer.
Explanation: According to section AA.2.4 of EN 61010-2-030, measuring circuits with­out any measurement category are intended for measurements on circuits which are not directly connected to the mains.
Logic probe (9)
The connector for logic channels can be used if the Mixed Signal Option R&S RTCB1 is installed. The option provides a logical probe with 8 digital channels (D0 to D7).
The maximum input voltage is 40 V (peak) at 100 kΩ input impedance. The maximum input frequency for a signal with the minimum input voltage swing and medium hystere­sis of 800 mV (Vpp) is 300 MHz.

4.3 Operating Concept

The general operating concept is based on a few key principals, recurring with various settings and functions:
Keys work in one of these ways:
The key opens a soft menu when pressed once. It closes the soft menu when
pressed a second time.
The key activates a specific function. Pressing this key a second time deacti-
vates the function.

Signal Display
Depending on the requirements, the [Universal] knob in the Cursor/Menu section either selects a value, or navigates through menus. The COARSE/FINE key tog­gles between fine and coarse resolution of the [Universal] knob.
The "MENU OFF" key below the softkeys closes the current menu, or switches to the next higher level.
The effect of channel keys depends on the state of the selected waveform:
Activate the channel if the channel is off.
Selects the channel if the channel is on and the other channel is selected.
Switches off the channel if it is selected.
If a channel is selected, its key is illuminated. If a channel is on but not
selected, you see the signal on the display, and its key does not light up.
The menus include some navigation elements and usage principles.
Press the softkey to select or toggle a value. The selected value is marked in blue.
Some functions must be activated and require value selection. Pressing the softkey toggles between "OFF" and the last set value. Use the [Universal] knob to change the value.
A round arrow in the softkey indicates that the value is set with the [Universal] knob.
A small triangle on the bottom right of a softkey indicates an additional menu level.
If additional menu pages are available, the lowest softkey navigates through the menu pages. The current page is shown in the soft menu.

4.4 Integrated Help

The integrated help shows explanatory text about the selected function. The text in the help window is dynamically updated when you select another function.
1. To activate the integrated help, press the [HELP] key in the General section.
The help window opens, and the [HELP] key lights up.
2. If you no longer need help, press [HELP] again.

4.5 Signal Display

This chapter describes the display of signals and the available display modes.

VIRTUAL SCREEN
See Chapter 4.5.2, "Virtual Screen", on page 27.
DOTS ONLY
If enabled, only the acquired data points are shown. The data points are not connected by lines. If disabled, interpolated data points are also shown, and the waveform is a continuous line.
INVERSE BRIGHTN.
Iinverts the brightness of the displayed signals points. Normally, frequently captured dots are displayed more brightly than rare dots. If inverted, rare events are displayed with higher brightness. To capture rare events in a signal, this setting can be used in combination with persistence.
FALSE COLORS
Converts the brightness level of the displayed signal points to a color scale, ranging from blue, magenta, red and yellow to white. Due to the higher contrast, you can see signal details easily. This setting applies to all signals.
GRID
Sets the display of the grid: "LINES", "RETICLE", or "OFF".
INFO WINDOW
Info windows are small windows that appear on the screen depending on the current application. You can change the format of information windows:
"TRANSPARENCY"
Use the Universal knob to or the [KEYPAD] to change the value from 0% to 100%.

4.5.2 Virtual Screen

Normally, the grid of the R&S RTC1000 has 8 vertical divisions. It has also a virtual range of 20 divisions. These virtual divisions can be used entirely by the optional digital channels D0 to D7, the mathematical channels and the references signals. The analog channels can use up to ±10 divisions from the center. This allows a simple and clear display of many waveforms
Figure 4-2 illustrates the functionality of the virtual screen. The scroll bar next to the
grid indicates the position of the 8 visible divisions within the available 20 divisions. .
If activated and the vertical position is changed, the value of the verti­cal position is shown at the zero line.
If activated, the information on the acquisition status is shown. In nor­mal trigger mode, if the trigger condition is fulfilled, the information window shows a progress display for the post-trigger and pre-trigger. If the trigger condition is not met, the information window shows the time since the last trigger event ("Trig?"). In automatic trigger mode, no information is shown.
1. Press the [DISPLAY] key in the General section.
2. Activate "VIRTUAL SCREEN".
A scrollbar is shown to the right of the grid.
3. To activate or deactivate the scrollbar, press the [ SCROLL BAR] key.
The scrollbar is shown in blue if it is active.
4. If the scrollbar is active, use the Universal knob to move the display window within
the 20 divisions of the virtual screen.

4.5.3 Signal Intensity and Persistence

To change the intensity of the waveforms:
1. Press the [INTENS/PERSIST] key in the Cursor/Menu section until it lights up in
white.
2. Turn the Universal knob to change the intensity of the signal display from 0% to
100%.
To access further intensity and persistence settings:
1. If the [INTENS/PERSIST] key is illuminated in white, press this key again.
2. Use the menu functions to adjust the settings.
The following settings are available:
TRACE, GRID, BACKLIGHT
Use the Universal knob to adjust the waveform intensities, grid intensity, and the back­lighting.
PERSISTENCE
Persistence defines how subsequent captured waveforms are shown simultaneously. Older waveforms are displayed in darker color (they fade), and newer waveforms are displayed in lighter color. Thus, signals points occurring more frequently are displayed in lighter color. The display is similar to that of an analog oscilloscope

General Instrument Settings
Figure 4-3: Persistence function
"MANUAL"
"AUTOMATIC"
"OFF"
"BACK­GROUND"
You can set a duration of 50 ms to infinite by using the [universal] knob or the [KEYPAD] key. If a finite duration is selected, new signals are written on top of one another. The most recent captures are dis­played more brightly than older signals. For example, if 300 ms is selected, the display of the waveform becomes darker in 50 ms inter­vals and is erased after 300 ms.
The instrument sets the optimal persistence time.
Persistence is deactivated.
When enabled, older waveforms do not disappear entirely after the set persistence time. Instead, waveforms are displayed in the back­ground with low brightness. This display is useful for the analysis of peak values in signals, for example.
