The keys
37 38 39
on this control
panel area HORIZONTAL allow to
shift the trigger position horizon-
tally, either step-by-step or using
the smaller one of the knobs. The
backlighted key
39
controls the run
or stop modes; the key will light
up red in stop mode. The key
40
activates the zoom function, the key
44
the selection of the acquisition
modes, the key
42
the access to the
time base menus. The knob
43
allows
to adjust the time base speed.
To the left of the control panel there
are the soft keys
2
which control the
menu functions.
2.3 Screen
The HMO is equipped with a 6.5“
(16.5 cm) LED backlighted colour TFT
display with VGA resolution (640 x 480
pixels). In normal mode (no menus
shown) there are 12 divisions in X
direction. If menus are shown, this
will be reduced to 10 divisions. On
the left of the screen area little arrows [1] indicate the refe-
rence potentials of the channels. The line above the graticule
contains status and settings information such as the time base
speed, the trigger delay and other trigger conditions, the actual
sampling rate, and the acquisition mode [2]. On the right of
the graticule a short menu is shown which contains the most
important settings of the channel actually being displayed; these
may be selected using the soft keys [3]. Below the graticule,
measurement results of parameters and cursors, the settings
of the activated vertical channels, of the reference signal, and
of the mathematically derived curves [4] are shown. Within the
graticule, the signals of the selected channels are displayed.
Normally, 8 vertical divisions are shown; it can be virtually ex-
tended to 20 divisions which can be displayed using the SCROLL
BAR knob

2.4 Rearview
On the rear panel there are the mains connector [1], the re-
ceptacle for the interface modules [2] (USB / RS-232, Ethernet,
IEEE-488), the standard DVI connector [3] for the connection
of external monitors and projectors, the BNC connector for
the Y output [4](of the channel selected for triggering) and the
external trigger input [5]. With the two-channel models this
connector is located on the front panel.

2.5 Options
The HMO series instruments offer some options which allow you
to extend the areas of application considerably. The following
interface modules are available and may be installed by the
customer in the rear receptacle:
– HO740 (IEEE-4888, GPIB, galvanically isolated)
– HO730 (combination of Ethernet and USB with integrated
web server)
All HMO series instruments are prepared for mixed-
signal operation and have the appropriate connectors on the
front panel. Each of these connectors can be connected to an
8-channel logic probe HO3508, hence a maximum of 16 logic
channels is possible. Further options are the passive 500 MHz
Slimline 10:1 probes of the type HZ355, passive 1000:1 probes
with up to 4000 V of the type HZO20, active 10:1 probes with
<1 pF input capacity of the type HZO30, active difference am-
plier probes HZ100, HZ109 and HZ115 with up to 1000 Vrms
and 40 MHz, the current probes HZO50 and HZO51 with up to
100 KHz bandwidth and up to 1000 A, the 19“ rack-mount set
HZ46 and the type HZ99 transport bag for the protection of the
instruments.
2.6 Generalconceptofinstrumentoperation
HAMEG oscilloscopes are renowned for easy operation, based
on a few basic principles which repeat with the diverse settings
and functions.
– Such keys which do not open a soft menu (e.g. Quickview)
switch a function on, pushing the key again will switch the
function off.
