General information regarding the CE marking
HAMEG instruments fulll the regulations of the EMC directive. The
conformity test made by HAMEG is based on the actual generic- and
product standards. In cases where different limit values are applicable,
HAMEG applies the severer standard. For emission the limits for
residential, commercial and light industry are applied. Regarding the
immunity (susceptibility) the limits for industrial environment have
been used.
The measuring- and data lines of the instrument have much inuence
on emission and immunity and therefore on meeting the acceptance
limits. For different applications the lines and/or cables used may
be different. For measurement operation the following hints and
conditions regarding emission and immunity should be observed:
1. Data cables
For the connection between instrument interfaces and external devices,
(computer, printer etc.) sufciently screened cables must be used.
Without a special instruction in the manual for a reduced cable length,
the maximum cable length of a dataline must be less than 3 meters and
not be used outside buildings. If an interface has several connectors
only one connector must have a connection to a cable.
Basically interconnections must have a double screening. For IEEE-bus
purposes the double screened cable HZ72 from HAMEG is suitable.
2. Signal cables
Basically test leads for signal interconnection between test point and
instrument should be as short as possible. Without instruction in the
manual for a shorter length, signal lines must be less than 3 meters
and not be used outside buildings.
Signal lines must screened (coaxial cable - RG58/U). A proper ground
connection is required. In combination with signal generators double
screened cables (RG223/U, RG214/U) must be used.
3. Inuence on measuring instruments
Under the presence of strong high frequency electric or magnetic
elds, even with careful setup of the measuring equipment, inuence
of such signals is unavoidable.
This will not cause damage or put the instrument out of operation. Small
deviations of the measuring value (reading) exceeding the instruments
specications may result from such conditions in individual cases.
4. RF immunity of oscilloscopes.
4.1 Electromagnetic RF eld
The inuence of electric and magnetic RF elds may become visible
(e.g. RF superimposed), if the eld intensity is high. In most cases
the coupling into the oscilloscope takes place via the device under
test, mains/line supply, test leads, control cables and/or radiation.
The device under test as well as the oscilloscope may be effected by
such elds.
Although the interior of the oscilloscope is screened by the cabinet,
direct radiation can occur via the CRT gap. As the bandwidth of
each amplier stage is higher than the total –3dB bandwidth of the
oscilloscope, the inuence of RF elds of even higher frequencies
may be noticeable.
4.2 Electrical fast transients / electrostatic discharge
Electrical fast transient signals (burst) may be coupled into the
oscilloscope directly via the mains/line supply, or indirectly via test
leads and/or control cables. Due to the high trigger and input sensitivity
of the oscilloscopes, such normally high signals may effect the trigger
unit and/or may become visible on the TFT, which is unavoidable. These
effects can also be caused by direct or indirect electrostatic discharge.

1 Installation and safety instructions
1.1 Setting up the instrument
handle can be set into
different positions:
A and B = carrying
C = horizontal operating
F = handle removal
G = operating using the feet‘s, batch use and for shipping in
original packaging
Attention!
When changing the handle position, the instrument
must be placed so that it cannot fall (e.g. placed on
a table). Then the handle locking knobs must be
simultaneously pulled outwards and rotated to the
required position. Without pulling the locking knobs
they will latch in into the next locking position.
Removal/tting of the handle: The handle can be removed in
position F, pulling the side parts outside the housing. Adding
the handle works vice versa.
1.2 Safety
electrical measuring, control and laboratory instruments and
was manufactured and tested accordingly. It left the factory in
In order to maintain this condition and to ensure safe opera-
tion the user is required to observe the warnings and other
all measuring terminals are connected to safety ground of the
mains. All accessible metal parts were tested against the mains
with 2200VDC. The instrument conforms to safety class I. The
oscilloscope may only be operated from mains outlets with a
safety ground connector. The mains plug has to be installed
prior to connecting any signals. It is prohibited to separate the

safety ground connection. If suspected that safe operation may
not be guaranteed do not use the instrument any more and lock
it away in a secure place.
Safe operation may be endangered if any of the following was
noticed:
– in case of visible damage.
– in case loose parts were noticed
– if it does not function any more.
– after prolonged storage under unfavourable conditions (e.g.
like in the open or in moist atmosphere).

1.3 Correct operation
Please note: This instrument is only destined for use by perso-
nnel well instructed and familiar with the dangers of electrical
measurements. For safety reasons the oscilloscope may only
be operated from mains outlets with safety ground connector.
It is prohibited to separate the safety ground connection. The
plug must be inserted prior to connecting any signals.
The oscilloscope is destined for operation in industrial, business,
manufacturing, and domestic sites.
1.4 Ambient conditions
Operating ambient temperature: +5 °C to +40 °C. During trans-
port or storage the temperature may be –20 °C to +70°C. Please
note that after exposure to such temperatures or in case of
condensation, proper time must be allowed until the instrument
has reached the permissible temperature, and until the con-
densation has evaporated before it may be turned on! Ordinarily
this will be the case after 2 hours. The oscilloscope is destined
for use in clean and dry environments. Do not operate in dusty
or chemically aggressive atmosphere or if there is danger of
explosion. The any operating position may be used, however,
requires the horizontal or inclined position.
Do not obstruct the ventilation holes!
are average values.
1.5 Warranty and repair
Prior to leaving the factory, each instrument is burnt in for 10
hours. By intermittent operation during this period almost all
defects are detected. Following the burn in, each instrument is
in all operating modes; the test gear is calibrated to national
standards.
The warranty standards applicable are those of the country
in which the instrument was sold. Reclamations should be
directed to the dealer.
Only valid in EU countries

1.6 Maintenance
Clean the outer case using a dust brush at regular intervals.
Dirt can be removed from housing, handle, all metal and plastic
parts using a cloth moistened with water and 1 % detergent.
Greasy dirt may be removed with benzene (petroleum ether) or
alcohol. Thereafter wipe the surfaces with a dry cloth. Plastic
parts should be treated with a suitable antistatic solution. No
agents as they may adversely affect the plastic or lacquered
surfaces.
1.7 CAT I
This oscilloscope is destined for measurements in circuits not
connected to the mains or only indirectly. Direct measure-
ments, i.e. with a galvanic connection to circuits corresponding
to the categories II, III, or IV are prohibited! The measuring
circuits are considered not connected to the mains if a suitable
-
surements on the mains are also possible if suitable probes
The measurement category of such probes must be checked
and observed. The measurement categories were derived
corresponding to the distance from the power station and the
transients hence to be expected. Transients are short, very fast
voltage or current excursions which may be periodic or not.
Measurement CAT IV: Measurements close to the power station,
e.g. on electricity meters
Measurement CAT III: Measurements in the interior of buildings
(power distribution installations, mains outlets, motors which
are permanently installed).
Measurement CAT II: Measurements in circuits directly con-
nected to the mains (household appliances, power tools etc).
contain circuit breakers or fuses.
1.8 Mains voltage
The instrument has a wide range power supply from 105 to
voltage selector.
The line fuse is accessible on the rear panel and part of the line
input connector. Prior to exchanging a fuse, the line cord must
undamaged. It can be taken out using a screwdriver put into the
slot. The fuse can be pushed out of its holder and exchanged.
The holder with the new fuse can then be pushed back in place
against the spring. It is prohibited to ”repair“ blown fuses or to
bridge the fuse. Any damages incurred by such measures will
void the warranty.

In the Fig. 2.8 there are two basic soft menu elements for choosing
to press the soft key beside and the element is active (shown as
blue color). A second kind of selecting is shown on the lower two
menu entries. Pressing the respective soft key toggles between
the two choices, again the active selection is marked blue.
The menus are used as shown in Fig. 2.9 if they concern func-
tions which have either to be switched on or where values have
to set. The choice is between OFF and the value presented. The
round arrow in the right corner of the menu window points to
the universal knob which is to be used for selecting the value.
If there is a lower menu level, this will be indicated by a small
triangle in the right lower corner of the respective menu point.
If there are further pages on the same level, the lowest menu
point will be used for navigation. It shows the number of menu
pages on this level as well as the activated number of pages.

gnition of the attenuation ratio or just a cable is connected to
the instrument, the attenuation factor can be set manually in
the extended menu. This is possible for x 1, x 10, x 100 x 1000
5 Horizontal System (Time Base)
As well as time base settings, the
horizontal system comprises the
selection of the trigger position, the
zoom functions and the available
modes of signal capture and the
control for the marker function.
The knobs are used for the adjust-
ment of the time base speed and the
trigger position. The signal capture
modes are selected in the respec-
tive menus. There is a key provided
for activating the zoom function.
5.1 Capturing modes RUN and STOP
The capturing modes can be selected with the key RUN/STOP.
In RUN mode signals will be continuously captured; depending
on the trigger conditions selected, and displayed, erasing the
previously captured ones. If it is desired to store and further
analyze a signal and to prevent it being overwritten, capture

must be stopped by pushing the RUN/STOP key. While in STOP
mode capture is disabled and the key will light up red.
5.2 Time base adjustments
The large knob in the section of the control
panel is used for the selection of the time base speed. The
time base speed is displayed in the upper left hand corner
above the graticule. (e.g. „TB:500 ns“) To the right there is
the display of the trigger time position with respect to the
normal position. The normal trigger position is in the center
of the graticule such that 50 % of the signal display is before
and 50 % is after this trigger position. The X POSITION knob
allows continuous adjustment of the X position. The available
maximum values depend on the time base setting. By pushing
reference posi-
tion. The arrow keys
37
allow you to change the X position
divisions in the respective direction. If
marker function is chosen the arrow keys together with the
marker. The key opens a menu which allows you to
set the X position to its minimum and maximum positions or
chose the marker function by just a key touch. In addition,
there is a submenu NUMER.INPUT which allows entry of an
arbitrary X position.
5.3 Capture modes
this opens a display menu which offers the 5 basic modes of
capture:
– Normal:
In this mode the signals are captured and displayed.
– Roll:
This is a mode especially useful for very slow signals: the
signal „rolls“ slowly untriggered from right to left over the
– Envelope:
In this mode the signal will be displayed as in NORMAL, but
its minimum and maximum excursions will also be displa-
yed such that, with time, an envelope of the signal will be
displayed.
– Average:
Functions only with repetitive signals. The universal knob in
the section of the front panel is used to set
the number of signal periods for averaging, this is possible
in powers of 2 from 2 to 256.
Please note: Averaging reduces the bandwidth.
– Smoothing:
In this mode continuous averaging is used which allows in-
crease of the vertical resolution at the expense of bandwidth
reduction.
The second menu page is accessed by pushing the soft key next
to the menu „Page 1/2“, here, extended functions are available:
– RANDOM SAMPL:
For very fast signals displayed with the fastest sweep speeds
it can be advantageous to switch the instrument to Random
Sampling mode; in this mode very many signal periods are
used to generate a high resolution picture, provided the
signal does not change its shape. This is equivalent to a
sampling rate of max. 25GSa/s. The oscilloscope will not
automatically enter this mode, however, it is possible to
19
Subject to change without notice
select automatic switching to Random sampling >20 ns/
div..The mode can be disabled by pushing the soft key.
– PEAK DETECT:
At very slow sweep speeds fast signal details will not be
visible. By selecting this mode peaks will be detected. This
function can be switched on or off in the menu, it is also
possible to select automatic switching in.
All the preceding functions are normally off. The lowest item in
the soft menu allows you to select the preferred signal capturing
repetition rate, there are 3 options:
– MAX. REP RATE:
In this mode an optimum combination of sampling rate and
memory length used will be selected automatically such that
the signal capturing rate will be maximized.
– MAX. SAMPL. RATE:
In this mode the maximum possible sampling rate will be
used.
– AUTOMATIC:
This mode is the standard mode: the instrument always
selects the optimum combination of capturing and sampling
rates (full memory length used).
5.4 ZOOM function
memory depth of 2 MB per
channel, this allows you to record long complex signals which
can be analyzed in detail with the ZOOM function. Push the ZOOM
key to activate this function. The screen will be partitioned into
two graticule areas: the top one displays the whole time base
window; the lower one displays the zoomed portion of it. The
zoomed portion will be indicated in the upper display by two
blue cursors. With multi channel displays all channels will be
zoomed by the same factor and on the same portion.
In Fig. 5.2 a signal was recorded for 12ms, the zoom window
is shown with a time scale of 100µs/div. The time base speed
display in the left upper corner is shown with a grey background,
the zoom time base display is shown in white. This means
that the large knob in the horizontal menu is now available
for changing the zoom factor. This knob also features a push
contact; if the knob is pushed, the time base display will change
to white, and the zoom time base display to grey: now the knob
is available for changing the time base setting. This allows you
to change time base settings without leaving the zoom mode.
By pressing the knob again, the cursors limiting the zoom area
will be shown pronounced in white, now the knob will also allow
to change the zoom area. The position of the zoomed area can
now be shifted with the small knob in the horizontal area of the
front panel over the whole signal. If pushing the large knob as
time base setting and not
the zoom factor, the small knob regains the function of shifting
the trigger position so the relationship of pre to post trigger
record can be changed.

Now the curve can be shifted with the position control knob, the
marker set will go along. If another interesting point is found,
another marker may be set after the point has been shifted to
the graticule center. By this method up to 8 interesting points
of a curve may be marked. By pressing one of the arrow buttons
the next marker left or right of the center will be shifted to the
center. In order to erase a marker, shift it to the center and
erased by pressing the respective soft menu key.
By centering the markers with the arrow buttons a comparison
of signal portions marked in the ZOOM mode is possible, simply
and very fast.

– SOURCE: opens the menu for the selection of the trigger
source.
– FILTER: opens the menu for the selected trigger type in
order to select the exact trigger conditions.
Additional keys are provided for the selection of the trigger
6.1 Trigger modes Auto, Normal, Single

of the status line top center above the graticule the type selected
will open and offer the available options.
trigger signal coupling can be selected:
DC: The trigger signal is used with its dc content.
AC: The
HF: The
The trigger level is no longer adjustable. This mode
should only be used with very high frequency signals.
LOW PASS: The low pass
NOISE RED.: The low
frequency interference.
The coupling modes low pass and noise reduction can not be
simultaneously selected, but they can be used with DC or AC
coupling.
