Information
                                    The LF Synthesizer PM 5190 is a versatile high performance
signal Generator. It produces three wave forms, namely sine
wave, square wave or triangular wave form in the frequency
range from 1mHz to 2MHz.
The instrument is designed for most professional
applications, where a stable signal source is asked for, for
development laboratories, including calibration purposes and
advanced educational programs.
The frequency settings of the Synthesizer are highly
accurate due to X-tal controlled generation. All basic
signal parameters, i.e. frequency, amplitude, dc offset and
wave form are set via keyboard in the local mode of
operation. In addition all these parameters are remotely
programmable via the built-in IEC bus Interface. In local as
well as in remote operational mode these parameters are
indicated by a bright seven segment LED display in
combination with dimension and wave form LED 1s.
A microprocessor represents the central data processing and
Control Unit of the instrument. It accepts input data from
the keyboard or via IEC bus. After diagnosting and
processing these data it stimulates the various functional
units of the instrument for proper response via assigned I/O
ports. In case of incompatible settings the microprocessor
initiates the LED display flashing.
A rub-out facility allows fast alteration or correction of
keyboard input data.
The inherent signal generation technique of the instrument
is called direct digital signal synthesis:
Succeeding digital samples of the signal are computated by a
fast processing TTL circuitry and converted to analogue.
This technique effects extreme fast responding on alternate
frequency settings.
Remote data programming is organized according to the
international standard "Interface System for Programmable
Measuring Apparatus", called IEC bus. So via the built-in
IEC bus Interface the PM 5190 cooperates with all Philips
and non-Philips IEC bus instruments.
The dc output voltage may be selected separately or whenever
used as dc offset voltage added to the output signal.
The Generator provides external amplitude modulation facility.
For TTL circuitry testing and stimulating a separate TTL
output is available.
All these facilities are built into a compact portable
housing. The clearly designed frontpanel and the simplicity
of keyboard input as well serve for convenient operating the
instrument.
