diyAudio Forums Archive > Top > Amplifiers > Solid State Help Choosing Test Equipment - Click HERE for Original Thread hifileslie I have got the bug and am heavily into building and modifying transistor and chip amps but have no real test equipment to help me. I have just purchased a used oscilloscope, but need a signal source. I have seen function generators and audio oscillators for sale. Is the oscillator a simplified function generator? Will either do the job? If the price is right which should I go for? tschrama Build your own oscilator..:cool: it's not that hard.. search the forum... less than 0.01% is easely possible... gr, Thijs lgreen You could think about getting a tektronix TM mainframe, there are versions with 3, 4 and 6 plug in slots. Here is a 3 slot version. http://cgi.ebay.com/ws/eBayISAPI.dl...8&category=1504 Then add a FG501 or FG501a function generator. I would get a FG rather than an oscillator, since it makes different waveforms (square, triangle, sine). http://cgi.ebay.com/ws/eBayISAPI.dl...&category=25405 And you would have 2 spots left for something else, maybe a power supply? http://cgi.ebay.com/ws/eBayISAPI.dl...&category=32720 Maybe a DMM? http://cgi.ebay.com/ws/eBayISAPI.dl...&category=25412 Here is a link to someone I have found helpful in obtaining test equipment for a good price, just send him an email. http://www.dilette.com/Main/ebay/ebaylist.htm (Looks like I cited to the same guy's auctions, I don't know him and just cited those to illustrate the different models available, no idea if he is good or not.)
