What Is an RF Signal Generator?
An RF signal generator is a test instrument used to produce known RF or microwave signals for testing receivers, transmitters, amplifiers, components, and complete communication systems. These instruments help teams evaluate frequency response, output level, modulation performance, signal quality, and system behavior.
RF signal generators are commonly used in aerospace and defense, wireless communications, semiconductor testing, electronics manufacturing, research, production test, and field service environments. Because signal generators often serve as the reference stimulus in RF testing, regular calibration helps confirm that output frequency, power level, modulation performance, and signal purity remain accurate, traceable, and within specification.
Common RF Signal Generator Types
SIMCO supports calibration for common RF signal generators and related signal sources, including:
- RF and microwave signal generators used for RF system testing and validation
- Analog RF signal generators used for standard continuous-wave and modulated signal output
- Vector signal generators, or VSGs, used for complex digital modulation and communication signal testing
- Arbitrary waveform generators used for RF applications requiring custom or complex signal creation
- Synthesizers and RF sources used for stable, precise frequency generation
- Signal source modules used in automated or modular test systems
- Function generators used for test signal generation
- Modulation sources and generator options supporting AM, FM, PM, pulse, I/Q, digital modulation, and phase noise applications
- Frequency references and high-stability options used for precision timing and frequency control

Why RF Signal Generator Calibration Matters
RF signal generators can drift over time due to component aging, thermal effects, frequent use, handling, environmental conditions, or normal operation. If a generator’s output frequency, power level, modulation accuracy, or spectral purity drifts outside specification, test results based on that signal may no longer be reliable.
Calibration helps support:
- Signal accuracy: Confirms frequency, output level, modulation, and related RF performance remain within required tolerances.
- Reliable RF testing: Helps ensure receivers, transmitters, amplifiers, components, and communication systems are tested with accurate and repeatable signal sources.
- Compliance and audit readiness: Provides traceable documentation for quality systems, customer requirements, and regulated environments.
- Risk reduction: Helps reduce false test results, failed validation, incorrect troubleshooting decisions, rework, and quality escapes.
