A standard function generator produces basic waveforms like sine, square, and triangle. An Arbitrary Waveform Generator (AWG) allows you to define custom, complex signal shapes using software.
Function Generators Component Intelligence
Select the right signal source for your circuit characterization and validation needs.
What are Function Generators components?
Function generators provide precise electrical waveforms for testing and validating electronic circuits. Key selection criteria include frequency range, waveform types (sine, square, ramp, pulse), output impedance, and whether the unit supports arbitrary waveform generation (AWG).
How to Choose Function Generators Components
Focus on the signal integrity and flexibility required for your specific test bench application.
Frequency Range
Ensure the generator covers your highest required frequency with sufficient headroom for harmonic testing.
Waveform Versatility
Determine if standard functions suffice or if you require an Arbitrary Waveform Generator (AWG) for custom signal profiles.
Output Impedance
Match the generator output impedance (typically 50Ω) to your device under test to prevent signal reflections.
Sample Rate & Resolution
For digital or complex signals, higher sample rates and vertical bit resolution are critical for signal fidelity.
Connectivity
Check for USB, LAN, or GPIB interfaces if you need to automate test sequences via PC software.
