Buying advice

When choosing a function generator, consider the frequency range, number of channels, waveform types (e.g., sine, square, arbitrary), and modulation capabilities. For professional use, prioritize signal accuracy and build quality; for hobbyists, budget-friendly options like FeelTech offer good value. Ensure the product is listed under 'Industrial & Scientific > Test, Measure & Inspect' on Amazon to confirm it's a genuine test equipment item.
