The AC main power switch also interrupts the power supply of the OCXO.
When you power up the instrument, be sure to comply with the warm-up phase speci-
fied in the data sheet before you start measurements.

USB Device
USB 3.0 interface of type B (device USB), to be used for remote control of the instru-
ment.
USB
Two USB type A connectors that comply with standard USB 3.1 gen 1. They are used
to connect devices like keyboard, mouse and flash drive to store and reload instrument
settings and measurement data.
Note:
Electromagnetic interference (EMI) can affect the measurement results. To avoid
any impact, do not use USB connecting cables exceeding 1
m.
LAN
8-pin RJ-45 connector used to connect the instrument to a Local Area Network (LAN).
It supports up to 1000 Mbit/s (10/100/1000BASE-T Ethernet).
HDMI
HDMI Version 2.0 connector for an external monitor or projector. The monitor shows
the complete content of the instrument's screen.

DisplayPort
DisplayPort connector for an external monitor or projector. It supports Disp+
version 1.3.
Ext Trigger In
The BNC connector for external trigger input is used to control the measurement by an
external signal. The input impedance can be selected in the trigger configuration, the
values are 50
Ω
and 1
M
Ω
. The trigger level can be set from -5
V to 5
V. The maximum
input voltage is 30
V
RMS at 1
M
Ω
input impedance and 7
V
RMS at 50
Ω
input impe-
dance.
Trigger Out
The BNC 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
RTO6 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
M
Ω
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 the "Trigger out" action for the trigger or test.
You can adjust polarity and length of the pulse. The default is a positive pulse of
100
ns. The delay is 800
ns.
