Signal generators (also referred to as ‘signal gens’) and analysers are indispensable instruments for creating, modifying and meticulously evaluating electronic signals across a multitude of industries. These sophisticated tools empower engineers and technicians to design, rigorously test and efficiently troubleshoot electronic circuits and complex systems with exceptional precision and reliability.
A signal generator is capable of producing a diverse range of waveforms with highly controlled frequencies, amplitude and intricate modulation capabilities. When paired with a spectrum or signal analyser, these instruments form powerful combinations, adept at thoroughly characterising signal performance, ensuring signal integrity and validating compliance for a wide array of demanding applications.
Types of Signal Generators
There are many kinds of signal generators and analysers available, including:
Frequency Counters
Frequency counters are used for measuring frequency in several oscillations/pulses per second for a periodic electronic signal. Typical test subjects include transmitter carriers, oscillators in a circuit, signals on a line or any component through which the frequency of a steady repetitive signal can be tracked.
Waveform generators and accessories are used to inject waveforms into a Device Under Test (DUT) for tracking and analysis testing. Arbitrary Waveform Generators (AWGs) can generate a broad range of arbitrarily defined signals, unlike function generators which offer a limited set of standard waveforms. Common accessories include various options for memory and bandwidth upgrades.
Function Generators
Function generators are essential tools for creating electronic signals in a variety of waveforms for testing and analysis. They provide periodic waveforms with controllable frequency ranges and amplitude outputs, offering a standard set of signal shapes for common testing scenarios, unlike Arbitrary Waveform Generators (AWGs) which can produce custom waveforms.
Pulse Generators
Pulse generators are specialised instruments used to inject precise pulse signals, which can be digital, analogue or a combination of both, into Devices Under Test (DUTs) for various testing purposes. Certain advanced pulse generators also incorporate digital delay generation capabilities, enabling them to precisely time and trigger external components like lasers and optical modulators using a stimulus or clock signal.
Spectrum Analysers and Accessories
Spectrum analysers are essential tools for analysing the frequency spectrum of radio frequency (RF) and audio signals, enabling engineers to effectively test and diagnose the performance of electronic circuits and systems. These instruments display the signal amplitude as a function of frequency, providing valuable insights into signal characteristics. Common accessories like probes for signal measurement and antennas for receiving radiated signals enhance the functionality and application scope of spectrum analysers.
Benefits of Signal Generator Analysers
Signal generator analysers offer significant advantages for engineers and technicians working with electronic signals. Here are some key benefits:
Precise Signal Verification
A signal measurement device within a signal generator analyser allows for accurate verification of the generated signal output, ensuring the signal meets the required specifications for frequency, amplitude and modulation.
Comprehensive Signal Analysis
These instruments often combine signal generation equipment with analysis capabilities, enabling users to characterise signal purity, measure harmonics and assess signal fidelity in one integrated unit.
Efficient Testing and Troubleshooting
By generating a test signal and immediately analysing its characteristics, a signal generator analyser streamlines testing procedures and aids in quickly identifying and resolving signal-related issues.
Versatile Signal Generation
A quality signal generator can produce a wide variety of waveforms and modulations, and when coupled with analysis, allows users to confirm the accuracy of these diverse signal types
Cost and Space Savings
Combining generation and analysis functions into a single instrument can reduce the need for multiple standalone devices, leading to potential cost savings and a more efficient use of lab space when you buy signal generators.
How do Signal Generator Analysers Work?
Signal generator analysers function by integrating two key capabilities: precise signal creation and comprehensive signal analysis. The signal generator component employs digital synthesis techniques to produce a wide array of waveforms with accurate control over frequency and amplitude. This generated signal output is then seamlessly routed within the instrument to the analyser section, which uses Digital Signal Processing (DSP) to measure parameters like frequency, modulation and distortion.
In industrial settings, these tools are vital for testing communication systems, calibrating equipment and troubleshooting electronic issues, ensuring the performance of everything from wireless devices to aerospace systems.
Applications of Signal Generator Analysers
Signal generator analysers are indispensable tools across various technology-driven industries. Here are some key application areas:
Telecommunications
In telecommunications, signal generator analysers are crucial for testing and verifying the performance of communication networks and devices. They are used to generate and analyse signals for cellular networks, Wi-Fi systems and satellite communications, ensuring signal integrity and quality for reliable data transmission and voice calls.
Electronics Manufacturing
During the manufacturing of electronic components and devices, the signal measurement capabilities within these instruments are vital for quality control. They help verify the output and performance of oscillators, amplifiers and other circuits, ensuring that products meet stringent specifications before they reach the market.
Research and Development
For engineers and scientists in R&D, a precision signal generator combined with analysis features is essential for characterising new electronic components, testing novel communication techniques and troubleshooting experimental setups. They provide the flexibility and accuracy needed to explore and validate cutting-edge technologies.
How to Choose the Right Signal Generator Analyser?
Selecting the ideal signal generator analyser requires careful consideration of your specific application requirements. Some key factors to evaluate include:
- Frequency Range: Ensure the instrument's frequency signal generator and analysis capabilities cover the necessary minimum and maximum frequencies for your testing.
- Signal Accuracy and Purity: Assess the required precision in signal generation, considering frequency accuracy, amplitude flatness and harmonic distortion for reliable measurements.
- Bandwidth: Verify that both the generation and analysis bandwidth are sufficient for the types of signals and measurements you'll be performing.
- Power Output: Consider the required output power of the signal generator for your testing needs. Certain applications, such as amplifier testing or simulating strong signals, may necessitate a signal generator with higher electrical output capabilities.
- Compatibility: Ensure compatible interfaces (GPIB, USB, Ethernet) for seamless integration. For high-speed networked setups, prioritise Gigabit Ethernet and high-bandwidth cabling like Cat 7 cables to maximise performance.
