This has to be the best signal/function generator available for educational use! Developed in conjunction with physics teachers and designed specifically for education, this unit provides all the functionality you need for physics teaching. really useful feature for those less familiar with using signal generators is that for basic use, you just operate two buttons: One for frequency and one for amplitude that's it! There is, of course, far more sophistication for those who require it. If you want to change waveform or to utilise the step and sweep modes, the display keeps you updated on the status of the generator. Unique frequency control: The frequency is set by speed sensitive button. Turn slowly to set the display's last digit, turn faster and the response accelerates designed to work intuitively in practical experiments. Drives speakers, vibration generator etc. directly: The built-in 10 power amplifier effortlessly drives power appliances e.g. vibration generator. The amplifier can deliver more than amp for all frequencies between 0.001 Hz and 100 kHz. Step mode: In many applications you need to study physical system at fundamental frequency and at different multiples of that frequency. The special step feature makes this task incredibly easy. Once the fundamental frequency has been determined (e.g. of spring connected to vibration generator), other harmonics (or overtones) can be demonstrated by simply pressing button, which changes the frequency to progressive multiples of the fundamental frequency. Sweep mode: The generator can sweep through frequency range in order to discover eventual resonances. You decide the frequency range and the speed. You have the choice between linear sweep (fixed number of Hz per unit time) and logarithmic sweep (fixed number of octaves per unit time). Advanced Features: The generator connects to your PC through standard USB cable and acts as USB flash drive. Custom defined waveforms (e.g. created by means of spreadsheet) can be saved to the generator. Sequences of settings can be programmed for automatic execution.
