Signal Generator for Accurate Testing & Measurement

Signal generators play a crucial role in various major industries, such as electronics and telecommunications. But whatever your project or industry, you should strive to obtain a signal generator that’s durable, dependable and can accommodate digital and analog systems.

At Auscom Computers & Controls, we offer reliable and high-quality signal generators that you can use for your projects — whether it’s for testing, designing or troubleshooting.

Digital signal generators

Digital signal generators produce signals using digital circuits and software algorithms. Our digital signal generator can produce precise waveforms, frequencies and timing with high accuracy and stability. Such devices can also provide modulation, distortion and noise functions, so you can use them in digital system design, communication systems and radio frequency testing.

The advantages of digital signal generators include:

  • They produce high-precision signals using a combination of digital-to-analog converters (DACs) and direct digital synthesizers (DDS).
  • They store waveforms and settings in memory, making it easy to recall and reuse them.
  • They create complex and arbitrary waveforms that are difficult or impossible to do with analog signal generators.

Analog signal generators

Analog signal generators produce signals using analog circuits such as oscillators, filters and amplifiers. Our analog signal generators can produce all the industry standard signals such as current (0-20ma, 4-20ma), voltage (0-5v, 0-10v) and resistance (PT100, PT1000, Thermistor, etc).

The advantages of analog signal generators include:

  • They are simpler in design and lower in cost compared to digital signal generators.
  • They provide a broad range of signals with good frequency resolution and stability.
  • Their output can be adjusted using manual or automatic controls, allowing the operator to fine-tune the signal to match specific requirements.

Analog vs Digital — Which should you choose?

When deciding what kind of signal generator to use, it’s important to consider the specific needs of your application. If you require precise waveform generation and frequency accuracy for testing and developing digital systems, an oscilloscope with signal generator would be the best option. On the other hand, if you are looking for a simpler and more cost-effective solution for audio and radio frequency testing, an analog signal generator like our Analog 0-5V 0-10V 4-20mA Signal Generator Rechargeable Battery Pocket Simulator may be the way to go.

It’s also worth noting that there are hybrid signal generators that combine the features of both digital and analog signal generators. These can be a great choice for those who require a balance of precision and simplicity in their testing and measurements. Overall, the right choice will depend on the specific requirements of your electronics and telecommunications project.

How accurate is an analog signal generator?

It depends on the design and quality of its components. Analog signal generators typically have good frequency resolution and stability.

How accurate is a digital signal generator in terms of frequency and phase?

Digital signal generators are highly accurate in terms of frequency and phase, as they use direct digital synthesizers (DDS) and digital-to-analog converters (DACs) to generate signals. They can produce complex and arbitrary waveforms that are difficult or impossible to create with analog signal generators.

What kind of maintenance and calibration is required for signal generators?

Signal generators require regular maintenance and calibration to ensure accuracy and reliability. This includes periodic cleaning and inspection of the internal components, as well as calibration of the output signal using an external reference signal or calibrated instrument.

How do I troubleshoot common issues with my signal generator?

When troubleshooting your signal generator, you should first check the power source and connections to ensure they are functioning properly. You should also check the settings and controls to make sure they are set correctly. If you’ve purchased your signal generator from us, don’t hesitate to send us a message so that we can assist you.
