Buying advice

Consider the frequency range and number of channels you need. For general lab use, choose a well-known brand like BK Precision or Rigol for reliability. For budget-conscious projects, FeelElec or Koolertron offer good features at low cost. If you need high precision and advanced waveforms, look for arbitrary waveform generators with higher sample rates. Always verify that the product is listed under 'Industrial & Scientific > Test, Measure & Inspect' to ensure it meets your professional needs.
