I did some bench tests with a DAC, an audio amp (NOT the one in the schematic) and a 6V 2.5VA to 240V 50/60Hz transformer. It is 5ms long and would, at the maximum rate, equal 200Hz. News: Message from Admin:I have set a new Logo for the forum and my Youtube channel. Is this approach going to work, or am I heading in completly the wrong direction?Īs a bare minumum I need to reproduce the following waveform. Login with username, password and session length.

The equipment needs to be portable so it will run from a battery.

This tutorial includes descriptions of signal generator terminology and specifications. Each tutorial in this series, will teach you a specific topic of common measurement applications, by explaining the theory and giving practical examples. The primary coils go through a relay so they can be disconnected from the equipment's output terminal. This tutorial is part of the National Instruments Signal Generator Tutorial series. It can create multiple waveforms, sweep, fire single or repeating tone. I've based it around a 3 watt fully differential audio amplifier driven by two 12 bit DACs (an MCU will control the two DACs.) The amplifier output drives the secondary coil of a transformer - currently 6V secondary and 240V primary 50/60Hz. SigJenny turns your PC into a flexible and powerful audio signal generator for free.
The pulses are of a fixed length, but are sent at a variable frequency (So there are gaps between pulses for anything below max frequency.įor Example: A sawtooth wave where the wave length is 2.5 milliseconds, and one complete wave may be sent anywhere from once every second to 400 times a second. I need to generate various bipolar pulses with a peak no load voltage of around 120V, but at very low power - around 3 watts maximum. This schematic is as far as I've got and I wanted to sanity check the basic approach before I continue as I'm used to working on low voltage DC stuff.ĮDITED because I completly mischaracterised the nature of the wave forms: Choose from the different themes and styles. I'm trying to design a high voltage AC signal generator for some lab experiments. With VEEDs audio waveform generator, you can add stunning sound waves to your videos in just one click.
