EXT TRIGGER INPUT
The female connector for external trigger input is used to control the measurement with
an external signal. The input impedance is 1 MΩ for instrument with < 1 GHz band-
width. On instruments with 1 GHz bandwidth, the input impedance is selectable, the
values are 50 Ω and 1 MΩ. The trigger level can be set from -5 V to 5 V. The maximum
input voltage is 150 V peak.
TRIGGER OUPUT
The BNC connector for external trigger ouput is used to provide the internal trigger sig-
nal of the oscilloscope to trigger other instruments for synchronized measurements.
When a trigger occurs, the R&S RTM creates a pulse of 5 V with a source impedance
of 50 Ω and delivers it to the external trigger output.
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.
By default, the trigger output is off. To enable the trigger out signal, select SETUP >
"Trigger Output" > "Output". Here you can adjust also the polarity and the length of the
pulse. The default is a positive pulse of 1 μs.
GBIP Interface (Option RTM-B10)
Interface for remote control with GBIP. The option replaces the LAN / USB type B inter-
face module on the rear panel. Thus, remote control is possible either with LAN con-
nection, or with GBIP.
3.3 Right Panel
At the right side of the instrument you find the connectors for digital probes, POD 1 and
POD 2. The hardware module and digital probe come with the Mixed Signal Option
R&S RTM-B1. The module provides connectors for two logical probes with 8 digital
channels each (D0 to D7 and D8 to D15).
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 of 500 mV (V
pp
) is
400 MHz.
