INTRODUCTION
The PM 5131 function generator is an instrument designed for applications extending from the educational
to the general purpose area.
5
It produces sinewave, triangular and squarewave output signals, the frequencies of which are adjustable in three
logarithmical sub-ranges from 0.1 Hz to 2 MHz. The frequency vernier allows the frequency setting to be
varied from -20 % to +20 %.
The output voltage is continuously adjustable up to 30 Vpp and can be attenuated in steps of 10 dB down to
60 dB.
A continuously adjustable output voltage can be selected separately or whenever used as d.c. offset voltage
added to the selected output signal.
The generator provides a more than 3 decade sweep facility with adjustable sweep range and a variable sweep
time from 10 to 150 secondes. For instance it is possible to cover the audio frequency range of 20 Hz to
20kHz in one continuous sweep. Moreover external sweep and frequency modulation can be performed.
For TTL applications a separate output is available.
The ergonomic design of the controls and sockets serves for convenient operating the instrument.

TECHNICAL DATA
General information:
On delivery from the factory, the instrument complies with the safety regulations of measuring and control
equipment. The information and warnings contained in this instruction manual must be followed by the user
to ensure safe operation and to maintain the instrument in a safe condition.
Only data with indicated tolerances or limits are guaranteed; data without tolerances are given only for
guidance.
All specifications will be met after a warm-up time of 30 min. when keeping the instrument in a constant
mounting position.
Inaccuracies (absolute or in %) relate to the indicated reference value.
