TENMA - 72-455A - AUDIO SIGNAL GENERATOR, FREQUENCY, 1MHZ 5 5 1 1
Low Dollar Quality The product description does not give much of this information, which you probably want to know: It's actually 120 / 240 volts, with an external voltage select switch, it comes with a 240 V mains plug, but you can plug a 120 V standard mains cable into it easily, and that's what I had to do, here in USA. Internally, There is plenty of separation between power supply, circuit, output...and the individual sections are shielded and carefully positioned. In otherwords, it's low noise, low distortion, high immunity to external interference or noise. The frequency adjustment is a calibrated analog dial, old school. Of course, it's just an audio generator, high quality as you will find at low price. It's not a super expensive unit and good for an audio bench tech or experimenter. February 20, 2011
