Build your own adjustable signal source and explore five waveform types across a 5Hz–400kHz frequency range.
-
Waveform options: You can output sine, triangle, square, and forward or reverse sawtooth waves, with an adjustable 2–95% duty cycle.
-
Adjustable output: Set frequency and amplitude; at 12V, the output amplitude range is 0.1V–11VPP, with a DC bias range of -7.5V to 7.5V.
-
Signal details: You get 1% low-distortion sine wave, 0.1% triangular-wave linearity, and 50ppm/°C low temperature drift; supply voltage is 12–15V.
-
Kit and size: The ICL8038 and high-speed op amp circuit uses through-hole components on FR4 and acrylic. You receive the DIY kit and English manual; the board measures about 7.8 × 5cm, and the finished unit about 8.7 × 6 × 1.7cm.
