Signal Generators

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.

A high-quality simple-to-use student signal generator with a range of applications. Operated with just three buttons: Waveform, Frequency and Amplitude. There is a single output, provided with 4 mm safety sockets. The output can easily drive a speaker or vibrator with ample amplitude for resonance and diffraction experiments. The frequency range extends well beyond the audible range. The lowest frequencies are suitable for ""slow motion AC"" experiments. Unique frequency control The frequency is set with a speed-sensitive button. If you turn slowly, the last digit of the display is set. Turning faster, the response accelerates smoothly. The generator covers the six decades from 0.05 Hz to 50.00 kHz in a single range. The frequency is stable within 0.005 % Three waveforms The generator provides sine, triangle, or square wave signals. Distortion of the sine wave is less than 0.25 % in the audible range (20 Hz - 20 kHz) and remains below 1 % throughout the frequency range (0.05 Hz - 50 kHz). Built-in power amplifier The signal amplitude is continuously adjustable from 0 V to a peak voltage of 7.5 V (15 V p-p; 5.3 V RMS). More than 1 A peak current can be supplied. The output is overload protected. Supplied with 12 V power adapter.

This signal generator and amplifier provides sine, square or triangular waveforms. Frequency selection is by a switched range and continuously variable fine adjustment control. The frequency is displayed on an LED display. All connections are via pairs of labelled 4 mm sockets with one of each pair connected to earth. An illuminated on/off switch is mounted on the rear panel adjacent to a fused IEC mains inlet. Enclosed in a robust metal case with a durable powder coated finish. Signal Generator Mode: •Waveforms - Sine, Square & Triangular, sinewave distortion 1% on all ranges, square wave rise time 1 µs approx. •Frequency Range - 0.1 Hz to 100 kHz in six ranges, accuracy ±5% on all ranges •Voltage Output - 0 to 10 V (peak to peak), continuously variable across all ranges & waveforms •4 Ω Output - Power output of 4 W over entire frequency & waveforms, will drive loudspeaker or other suitable devices •600Ω Output - Provides attenuation settings: x 1, x 0.1 & x 0.01, all ±5% Amplifier Mode: •Performance - Voltage gain 0 to 100, Input impedance 1 MΩ, Max. input 200 mV (pk to pk), Output spec. same as above •Frequency Response - Frequency response 1 Hz to 100 kHz (-3 dB bandwidth)

Sine and square wave generator. Frequency range 5 Hz to 50 kHz in four switched ranges plus a fine control. Accuracy typically ±10%. The output amplitude is continuously variable from zero to maximum 8 V peak to peak with maximum output power 1 W into 8 ohms. The output is taken from two 4 mm sockets mounted on the front panel. An illuminated on/off switch is mounted on the rear panel adjacent to a fused IEC mains inlet. Enclosed in a robust metal case with a durable powder coated finish.
