Quick Start Guide
2.9 Back Panel
On the rear panel there are the main power switch [1], the
receptacle for interface modules [2] (USB / RS-232, USB/
Ethernet, IEEE-488), the DVI-D connector [4] for the con-
nection of external monitors / projectors, the BNC connec-
tor for the AUX OUT [5] (selected channel for triggering)
and the external trigger [6]. With two-channel models this
connectorislocatedonthefrontpanel.Youcanalsond
an additional USB port [3].
2.9.1 DVI Connector
The rear panel of the oscilloscope includes a standard DVI-
D connector to connect external monitors and projectors.
The DVI-D connector can only send digital signals. This
means it is impossible to connect monitors or beamers
via their analog inputs. The R&S®HMO3000 series yields
a DVI signal with VGA resolution (640x480). This design
enables connectivity with all standard TFT monitors. Mo-
dernatscreensextrapolatethesignal,allowingusers
to see a full screen. Beamers can also be connected to
the R&S®HMO3000 series. Ideal beamers in this case are
those designed to be connected to computers / note-
books as these are also able to process a 640x480 pixel
resolution.

The connection to current HDTVs via HDMI adapter can be prob-
lematically. The most television sets expect an HDTV signal of at
least 720p as input signal.
3 Quick Start Guide
The following chapter is an introduction to the most
important R&S®HMO3000 series features and settings al-
lowing you to use the instrument promptly. The integrated
calibrator signal output is used as the signal source which
meansthattherststepswillnotrequireanyadditional
instruments.
3.1 Setting up and turning the instrument on
To optimally set up the instrument, position the handle so
that the display will be inclined slightly upwards. Plug the
power cord into the rear panel connector
1
on the front
panel. The display appears after a few seconds, and the
oscilloscope is ready for operation. Press the AUTOSET
key

until a beep. This will reset the most important os-
cilloscope settings to their default settings.
3.2 Connection of a probe and signal capture
Take one of the provided probes and remove the protective
cap from the tip. Apply the probe compensation box to the
BNC connector for channel 1 and turn it to the right until it
latches into place. On the right hand side of the screen, you
will see the short menu for channel 1.
Press the soft menu key to the right of each menu item to
