Designed for education
In our development team we include experienced physics
teachers. This ensures that the technical perfection goes hand in hand with usefulness.
For basic use, you just operate two large buttons: One for
frequency – one for amplitude. That’s it.
If you want to change waveform or to utilise the new step and sweep modes, the display keeps you updated on the status of the generator.
Unique frequency control
The frequency is set by a speed sensitive button. Turn slowly to set the display’s last digit. Turn faster, and the response accelerates softly. We have designed this function to work intuitively in practical experiments with common physics equipment.
Drives speaker, vibrator etc. directly
The built-in 10 W power amplifier drives effortlessly powerconsuming appliances as e.g. a vibrator. The amplifier can deliver more than 1 A for all frequencies between 0.001 Hz and 100 kHz and is directly coupled to the generator part - no switches or external cables complicates use.
Step mode
In many applications you need to study a physical system at a fundamental frequency and at different multiples of this frequency. The special step feature makes this task a breeze.
Sweep mode
The generator can sweep through a frequency range in order to discover eventual resonances. You decide the frequency range and the speed. You have the choice between a linear sweep (fixed number of Hz per time) and a logarithmic sweep (fixed number of octaves per time).
Advanced Features
The generator connects to your PC through a standard USB cable and acts as a USB memory stick.
Custom defined waveforms (e.g. created by means of a spreadsheet) can be saved to the generator.
Sequences of settings can be programmed for automatic execution.
