Author Topic: Audio Oscillator Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 05-24-2003 06:23 PM                    Can someone point me to (or display here) a schematic for a simple, adjustable audio oscillator? What I want is one where I can do a frequency sweep. I built a very simple one with a 555 chip, a couple of caps and resistors and pots but I'm not happy with the non sinusoidal output (I added an output cap to smooth it but still). The simpler the better.  |  IP: Logged Jon Bartow Master Film Handler Posts: 287 From: Massachusetts Registered: Nov 1999 posted 05-24-2003 07:50 PM                     http://sound.westhost.com/project22.htm  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-25-2003 10:31 AM                     The best oscillator I have used is the Loftec (now sold by goldline) it has a constant amplitude output a db meter and frequency counter. Also it can used to calculate impedance as well to build something similar isn't worth the time considering its low cost  |  IP: Logged Jean-Michel Grin Expert Film Handler Posts: 222 From: Geneva & Lausanne, Switzerland Registered: Jul 2002 posted 05-26-2003 12:23 PM                        For me the best hand-held audio oscillator is made by Neutrik , Minirator MR1 You find here an affordable audio generator: -Pink noise -White noise -Audio sine or square from 20 Hz to 20 kHz -Polarity test -Auto sweep (timing adjustable) -Balanced XLR and unbalanced phono output Check the following link: http://www.nt-instruments.com/X0-ASP-pLngCateId_217-pIntLevel_4-X1-default.htm For me this is a great tool; every tech should have one Bye,  |  IP: Logged
