Welcome to my ebay store! You will find your favorite products. Pass by do not miss.thank you! Product Detail 1KHz sine wave signal source The use of "Wien bridge" oscillation circuit, on-board voltage regulator with a 9V, incandescent light bulbs so steady output amplitude, frequency stability, low distortion, but also to facilitate the production of other frequency source. To reduce distortion, ensure product quality, the oscillation circuit resistance and capacitance are selected pairing, can rest assured installation. Both for audio test signal source bridge to be used as a signal source coupled regenerative power amplifier circuit production, more extensive use. Add a Schmitt trigger, you can output a square wave signal. ( --- welcome you to buy it in ayanhu81's ebay shop --- ) Common audio test signal frequency is 100Hz, 1KHz and 10KHz, corresponding respectively to the capacitor 0.1uF, 0.01uF, 10nF. Easy to use via a double-pole three-throw rocker switch can do the conversion. Demanding buyers do the best three of the board, a board one frequency, respectively, and adjust the waveform output level, so no interference, more stable and reliable. Input voltage: 9-15VDC 20mA Output voltage: 1KHz 1V ( --- welcome you to buy it in ayanhu81's ebay shop --- ) PCB color: Green new version PCB Size: 47×34mm FIG. 2 potentiometers are "waveform adjustment" and "output level adjustment." When adjusting the waveform, the best output waveform with an oscilloscope display, this adjustment is more accurate.
