Antennas/BalunsThis application note is designed to help the reader understand how balun transformers can be used in today’s RF/Microwave communication applications.

Software/OscilloscopeFreeware windows oscilloscope uses the sound card's input to measure signals. This means that the quality of the scope depends on the quality of your sound card. The scope automatically uses the highest sample frequency available at the input that you select

Software/Signal GeneratorFreeware windows Wave Generator use the sound card's output as sine wave output. A built in sweep algorithm is used by audio hackers to measure frequency repsonses of their amplifiers

Software/Signal GeneratorSweepGen turns a PC into an Audio Oscillator and Sweep Generator which can be used for testing audio or educational purposes. In conjunction with audio test instruments, you can make frequency response plots. SweepGen uses the sound card in your PC to produce sinewaves

Software/Signal GeneratorThis Test Tone Generator (TTG) turns your PC into a function generator and enables you to demonstrate, test and tune sound systems, create sound effects and a whole range of other uses to suit your needs. It can also be used for educational purposes.

Software/Signal GeneratorGenerating of up to eight independent oscillatory processes per each channel with separate frequency, initial phase and amplitude controls.

Software/Signal GeneratorSigJenny turns your PC into a flexible and powerful audio signal generator for free. It can create multiple waveforms, sweep, fire single or repeating tone bursts. You can save your sound as a wav file, display a frequency response, use SigJenny a bit like an oscilloscope, and do a very good impression of a police car!
