Logic Analyzer for signal analysis and efficient debugging in development projects

What a logic analyzer does

With a logic analyzer, you can simultaneously record several signals from electronic circuits that are located in a device as an embedded system or are part of a production system, for example.

Using test leads and test clips, you connect the logic analyzer to the respective inputs of the device under test; the measuring devices offer at least eight channels for this. The device then records the signals and displays them visually; for trigger measurements, the logic analyzer triggers the desired digital events beforehand.

Logic analyzers display the results of the recording in different ways and there are various functions:

- Time analysis (asynchronous measurement)
- Status analysis (synchronous measurement)
- Protocol analysis with insight into the system level (protocols such as SPI, UART, etc.)

Wide range of applications for logic analyzers

Logic analyzers are particularly useful for hardware development, software testing and targeted troubleshooting.

In practice, these measuring devices have proven themselves in numerous areas of application. For example, users use logic analyzers to check the functionality of an Arduino microcontroller.

Important areas of application are

• Function check
• Firmware troubleshooting
• Reverse engineering
• Protocol decoding

The right logic analyzer for your purpose

The technical features of a logic analyzer largely determine how precisely, comprehensively and flexibly digital and analogue signals can be recorded and interpreted. The sampling rate determines the maximum signal frequency that can still be recorded correctly, and the number of inputs determines how many signal sources can be monitored simultaneously. A high memory depth enables the recording of longer signal sequences in order to track even complex processes or sporadically occurring error states.

Saleae Logic 8: Sufficient for medium requirements

• Analysing I²C or SPI signals at moderate clock frequencies
• Identification of timing problems in simple control systems
• Monitoring of digital signal sequences at medium speed

The Saleae Logic 8 has eight inputs and can therefore record up to eight signals simultaneously. Thanks to its moderate digital sampling rate, it is designed for medium signal speedsand can therefore reliably cover typical applications in the field of digital circuits. The analogue sampling rate is also designed more for basic applications, but is sufficient to display basic signal curves. The large number of possible digital and analogue samples also ensures long-term recording so that events extending over time can be easily analyzed.

Saleae Logic Pro 8: Greater precision for more demanding scenarios

• Analysing signals at higher SPI bus clock rates or fast UART connections
• Detailed characterisation of analogue oscillations or transient phenomena
• Debugging of systems in which multiple components such as microcontrollers, sensor arrays and external memories work together

With the Saleae Logic Pro 8, the significantly increased sampling rate in both the digital and analogue range ensures a finer temporal resolution. This means that even rapidly changing signals and higher frequencies can be captured, which go beyond the capabilities of the standard model. Although the eight input channels remain unchanged, the improved performance values enable more demanding measurement scenarios in which more exact detailed analyzes, signal progressions and more precise evaluations are required. The high memory depth ensures longer-lasting measurements without loss of information.

Saleae Logic Pro 16: More flexibility for complex projects

• Analysing parallel buses with many data and address lines
• Multi-signal monitoring in highly integrated systems
• Long-term recordings in critical applications

With its 16 inputs and high sampling rates, the Saleae Logic Pro 16 is particularly versatile. Particularly complex circuits with numerous data, address and control signals can be comprehensively recorded here. It records many signals simultaneously and makes it possible to analyze the interaction of different components in detail. Complex error patterns or interactions can thus be better understood. Thanks to the enormous memory depth, detailed measurement data can be collected even over long periods of time and then thoroughly analyzed.

Frequently asked questions about our logic analyzers

Here we answer some frequently asked questions about our range of logic analyzers. Please feel free to contact us personally if you would like further advice.

What is a logic analyzer?

This is a measuring device that can record and visualise one or more signals from electronic circuits. It is used for tasks such as functional testing and debugging.

What kind of signals does a logic analyzer detect?

Logic analyzers record digital signals and, with the appropriate equipment, analogue signals too. This applies, for example, to the models from the brand manufacturer Saleae.

What types of logic analyzers are there?

These measuring devices can be divided into modular, portable and PC-based logic analyzers. The PC-based logic analyzer, which can be connected to a PC, notebook or tablet via USB, is particularly popular. You benefit from low acquisition costs and at the same time utilise the powerful memory of your computer.

What specifications should a logic analyzer meet?

Check whether the features and performance values match your requirements profile. For example, the number of channels, the maximum sampling rate and the maximum digital and analogue bandwidth deserve a look.

What is the difference between an oscilloscope and a logic analyzer?

Logic analyzers usually have significantly more channels, allowing you to carry out more complex measurements.
