Equipment - Function Generators

1. Overview

Function generators are electronic test equipment that generate precise AC signals with adjustable frequency, amplitude, and waveform. They play a critical role in designing, testing, and repairing electronic circuits by simulating real-world signal conditions. These instruments enable engineers to verify circuit behavior under controlled parameters, making them indispensable in R&D, manufacturing, and educational settings.

2. Major Types and Functional Classification

Type	Functional Features	Application Examples
Arbitrary Waveform Generators (AWG)	Custom waveform creation, high-resolution signal editing	Radar simulation, communication protocol testing
Signal Generators	Standard waveforms (sine, square, triangle), frequency sweeping	Component characterization, impedance measurement
Function Generators	Basic waveforms with variable duty cycle and offset	Educational labs, sensor testing
RFG Generators	High-frequency signal generation (GHz range)	Wireless communication testing, aerospace applications

3. Structure and Components

Typical function generators consist of:

Digital signal processor (DSP) for waveform generation
DAC (Digital-to-Analog Converter) module
Amplification and attenuation circuits
Control interface (knobs, touchscreen, or software)
BNC output ports with 50 impedance matching
Power supply unit with voltage regulation

4. Key Technical Specifications

Parameter	Importance
Frequency range: 1 Hz - 1GHz	Determines application versatility
Output amplitude: -20dBm to +30dBm	Enables testing under various power levels
Waveform resolution: 12-16 bits	Affects signal fidelity
