Function Signal Generator Series
A function signal generator produces simple, repeatable waveforms. At its core are an electronic oscillator and circuitry that create periodic waveforms. Modern instruments typically use digital signal processing (DSP) to synthesize the waveform and a digital-to-analog converter (DAC) to output a highly stable analog signal. Common outputs include sine, sawtooth, pulse, square, and triangle; an arbitrary waveform generator (AWG) can create user-defined waveforms. For oscillators operating at audio and above (> 20 kHz), typical modulation features include AM, FM, and PM to provide diverse test stimuli.
Quick notes
- Charge/discharge shaping: Traditional generators often shape waveforms via capacitor charge/discharge; capacitor stability directly affects waveform stability.
- Temperature effects: Capacitance varies with ambient temperature and is inversely related to output frequency, so warm-up may cause a short-term frequency dip. Designs often use DC fans to speed thermal equilibrium for better stability.
- Typical features: Basic outputs include sine, square, and triangle. Many models add AM/FM, as well as Sweep and Burst modes—useful for wireless and general communications experiments.
Applications
Function/AWG instruments provide standard or critical reference signals and are widely used in:
- Electronic circuit characterization and fault analysis
- Prototype testing in physics/electronics
- Production QC and line checks
- Audio and wireless (AM/FM/PM) education and measurement
- Radar/pulse system testing and embedded control simulation
For example, an arbitrary waveform function generator (e.g., UTG-2062A, ~15 MHz class) can build multi-segment sequences for real-world test conditions.
