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.

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:

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

"MANUAL"
"AUTOMATIC"

"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.
