Information

The Generator SPN is a programmable Synthesizer whose sinewave output signal features a wide level range and low distortion. It is suitable both for use in computer-controlled test assemblies (photo below) and for manual operation. Due to its attractive price and remote-control capability via the IEC bus, the SPN finds a wide field of use in production, service, research and development. Since the SPN combines latest technology and modern circuit design, it is able to comply with the most exacting requirements in measurements, e.g. in acoustics and hifi technology. There is also a large number of other fields in which accurate frequencies are required, for instance in telemetry and physics or in mechanical control processes. In addition, the outputs of two SPN generators can be connected in parallel for measuring non-linear distortions. Frequency Modern Synthesizer technology ensures highly accurate, crystal-referenced output frequencies from 1 Hz to 1.3 MHz with a frequency setting time of only 50 ms. The short setting time is important in computer-controlled test systems with a high measuring rate or for the generation of tone sequences such as those required for measurements on selective calling equipment. The frequency entered via the keyboard is read out on the display in five digits (smallest resolution: 0.1 Hz) with a floating decimal point. The frequency can be varied quasi-continuously using a rotary knob. The SPN offers another convenient way of frequency variation by frequency jumps with selectable step size and by calling up the standard octave and third-octave sequences. Logarithmic frequency variation is possible by entering a multiplication or division factor between 1.00 and 2.00. Reference-frequency input/output For external control (TTL levels), a frequency of 1 MHz is available at the reference-frequency connector. A frequency of 1 MHz may be applied for synchronization to an external reference source. Output level (sine wave output) Adjustable between 0.1 mV and 10 V with smallest resolution of 0.01 mV (depending on output impedance selected). The output level is read out in three digits with a floating decimal point on the level display (in mV, dBV or dBm). The output level entered can also be varied quasi-continuously or in steps, and it can be converted from one unit into another simply at the push of a key. The maximum output EMF is 10 Vrms. Distortion is as low as 0.03% in the frequency range from 50 Hz to 100 kHz, so that the SPN fulfils the most demanding requirements of the audio-frequency range.
