1 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 www.phywe.de, © All rights reserved 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 U pp

≈ 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

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 A fuse holder is located in the upper part of the plug and it can only be opened when the plug is withdrawn and by using a screwdriver or similar tool; replacement miniature fuse 5 mm x 20 mm, see type plate.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 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

R l

= 50 Ω , the maximum amplitude of the distortion-free output voltage is at least U pp

= 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 U pp

< 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: Scale value = 8, step 10

3

Frequency f = 8 Hz x 10

3

= 8 kHz

7 “Coarse frequency” step switch

For setting the decade factor for the scale value selected with the control knob (6). The starting value of the range is stated for each switching stage as a decade value.

There are a selection of six frequency ranges:

0.1 Hz... 1 Hz

1 Hz... 10 Hz

10 Hz...100 Hz

100 Hz...1000 Hz

1 kHz... 10 kHz

10 kHz...100 kHz

4 HANDLING

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 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).

5 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.
