SAFETY PRECAUTIONS
•
Carefully read these operating instructions completely
before operating this instrument. This is necessary to
avoid damage to it, as well as for user-safety.
Check that your mains supply voltage corresponds to
that given on the type plate fixed to the instrument.
Install the instrument so that the on/off switch and the
•
•
mains connecting plug are easily accessible. Do not
cover the ventilation slots.
Take care that no liquids or objects enter in through the
ventilation slots.
Only use the instrument in dry rooms in which there is no
risk of explosion.
Do not start up this instrument in case of visible signs of
damage to it or to the line cord.
Only use the instrument for the purpose for which it was
designed.
2 PURPOSE AND CHARACTERISTICS
The function generator can be used in student experiments,
practicals and demonstration experiments with three
selectable signal waveforms (sine, rectangular, triangular).
The frequency range extends from 0.1 Hz to 100 kHz.
The signal amplitude at the output can be adjusted up to a
peak value of Upp ≈ 20 V.
Application examples:
Producing sounds with a loudspeaker (e.g. Sound Head
03524.00).
- Measuring the frequency response of amplifiers and
filters.
Periodic excitation of oscillation circuits to obtain
oscillograph signals of damped oscillations.
Measuring alternating current impedances of coils and
capacitors.
Elementary experiments in spectral analysis.

.3 DESCRIPTION
4
The unit is accommodated in an impact resistant plastic
housing. A retractable carrying handle is recessed into the
sides of the unit. The handles can be folded down so that the
function generator is placed in a sloped position. Four rubber
feet ensure that the unit stands firm and they also enable the
unit to be stacked with units of a similar design, the rubber
feet being located in the cup-shaped depressions on the
lower unit to stop the upper one slipping.
The unit is connected to the AC mains with the supplied
connecting lead which is inserted into the equipment
connection plug on the back panel. A fuse holder is located in
the upper part of the plug and it can only be opened when the
plug is withdrawn and by using a screwdriver or similar tool;
replacement miniature fuse 5 mm x 20 mm, see type plate.
The “Amplitude” control knob should always be turned fully to
the left (≈ 0 V) before switching on the unit. This prevents
surprise effects (e.g. loud loudspeaker sound pressures
when testing amplifiers).
The function generator is ready for operation immediately
after switching on. However, with precision measurements a
warm-up period of about 15 min. should be allowed.
The mains switch for switching on the unit is situated in the
immediate vicinity of the equipment connection plug at the
back of the unit. All other functional elements and controls
can be found on the front panel.
1
BNC output
BNC connector for providing the voltage signal in all
three signal waveforms. With a load resistance
Rl = 50 Ω, the maximum amplitude of the distortion-free
output voltage is at least Upp = 10 V.
2
4 mm output sockets
The 4 mm sockets are wired in parallel to the BNC
socket. The 4 mm sockets are subject to the same
conditions as the BNC output.
3
„Offset“ control knob
A variable offset voltage of between –10 V and +10 V
can be added to the selected signal amplitude using the
offset control knob.
4
„Amplitude“ control knob
For continuous voltage adjustment up to an open-circuit
voltage of Upp < 20 V.
5
„Signal waveform“ step switch
For selecting from three time functions.
~ position : sine wave voltage
position : triangular voltage
position : rectangular wave voltage
6
„Fine frequency“ control knob
With a scale from 1... 10, for the continuous adjustment
of the frequency within the step ranges, cf. (7). The
frequency in Hz is the product of the set scale value
and the decade value set with (7).
Example:
7
3
Scale value = 8, step 10
3
Frequency f = 8 Hz x 10 = 8 kHz
HANDLING
The signal waveform is selected with the step switch (5).
The frequency selection is made with the step switch (7) and
the control knob (6). The accuracy of adjustment is about
10%. A check can be made with a frequency meter (e.g.
Electronic Digital Counter, 4 decade, 13600.93 or a similar
instrument).

NOTES ON OPERATION
This high-quality instrument fulfils all of the technical
requirements that are compiled in current EC guidelines. The
characteristics of this product qualify it for the CE mark.
This instrument is only to be put into operation under
specialist supervision in a controlled electromagnetic
environment in research, educational and training facilities
(schools, universities, institutes and laboratories).
This means that in such an environment, no mobile phones
etc. are to be used in the immediate vicinity. The individual
connecting leads are each not to be longer than 2 m.
The instrument can be so influenced by electrostatic charges
and other electromagnetic phenomena that it no longer
functions within the given technical specifications. The
following measures reduce or do away with disturbances:
Avoid fitted carpets; ensure potential equalization; carry out
experiments on a conductive, earthed surface, use screened
cables, do not operate high-frequency emitters (radios,
mobile phones) in the immediate vicinity. Following a
blackout failure, operate the on/off switch for a reset.
When the instrument is connected to a test object, the
permissible interfering radiation may be exceeded. The
operator must take all necessary precautions here to ensure
that proper functioning of other instruments in the vicinity is
not impaired.
