What is A Logic Analyzer?
Logic analyzers are the testing devices that are broadly utilized for evaluating complex logic circuits. They convert the received data into protocol decodes, timing diagrams, state machine traces. Logic analyzers are also very effective in correlating assembly language with the source-level software.
Advanced triggering capabilities of logic analyzers allow its users to perceive and analyze timing relationships between different digital signals. Though, oscilloscopes can carry out many of the operations of a logic analyzer but unable to manage the relative timing of an enormous number of signals.
Essentially, logic analyzers display the traces of several digital signals at a time in order for the users to easily monitor and investigate. They generally come with a variety of configurations from traditional to the smarter ones which possess a high level of flexibility and processing capacity.
They are typically designed for monitoring about 32 to 200+ channels simultaneously. Handling such a big line of digital signals enables them to track and find faults in much more complex systems. The horizontal time axis, as well as the vertical axis, are used for indicating low and high states on the display screen.
Digital signals are entered from different channels and transformed into the low or high state for advanced processing. Although various variants of these test devices are available in the market, they are broadly classified into three categories: Modular Logic Analyzers, Portable Logic Analyzers & PC-based Logic Analyzers.
They are especially attractive and useful for analyzing logic with many controllers like Raspberry Pi, Arduino, Peripheral Interface Controller (PIC), Mixed-signal processor (MAP), etc. Logic analyzers provide a comprehensive view of data movement and processing operations within many embedded systems at a time.
Buying Guide to Logic Analyzer
Since a wide range of logic analyzers are currently available in the market, how do you know which one is the best and right to align with your requirements? There is a lot of technical specification that need to be considered. While buying a logic analyzer following points should be kept in mind:
1. Type of Logic Analyzer
You have to decide which kind of logic analyzer are looking for? They came in three different types, portable, modular, and PC-based. Each type has a certain set of advantages and disadvantages worth considering.
- Portable logic analyzers are large boxes similar to an oscilloscope. They generally consist of a screen with various buttons and knobs. This usually does not require a separate computer.
- Modular type logic analyzers can be rack-mounted. They require a separate computer with specific software for collecting and analyzing data.
- PC-based are similar to modular analyzers that require a host computer to capture the visualization of waveforms.
2. Number of Channels
There is a technical specification that needs to check out. The most basic and important need is to figure out the number of channels available on the logic analyzer. Channel is an input line for receiving a digital signal. The number of channels varies from 8,16,32, 34, and so on. A large number of input channels enable you to debug parallel communication busses.
3. Sample Rate
The sample rate is the second most important consideration. It determines the shortest amount of time in which your analyzer can effectively measure different readings from captured signals. For example, if your device has a sample rate of 50 MS/s, it means it can sample a signal 50,000,000 times per second. A good rule of thumb is that you need a sample rate of digital signal 4 times faster than its frequency.
To help you understand what the sample rate is, you could read our article about ADC (Analog to Digital Converter). Read the “sampling rate” sub-title.
You need to examine the bandwidth of the logic analyzer. It shows the maximum level of frequency that a logic analyzer can handle.
5. Other Factors to Consider
Other factors like triggering, protocol, over-voltage protection, differential signals, output capability, ease of use, and support are also needed to be considered thoroughly.
Buying the best logic analyzer can be dismaying, but hopefully, this guide will help you to navigate some important technical specifications. When you are looking for a logic analyzer, search for different brands across different platforms. Compare the specifications, price, and most importantly certification of different logic analyzers. This process helps you to choose the most effective and cost-effective logic analyzer.
Conclusion: Which One that We Recommend
In this article, we listed the ten best logic analyzers along with their specs, pros, and cons. Each device is thoroughly investigated to get the best ones. The number of channels, sampling rate, bandwidth, and various other aspects has been discussed. In our opinion, Digital Discovery Digilent 471-033 logic analyzer is the best logic analyzer of all. The main reason behind considering this device is that it provides a maximum sampling rate of 800 MS/s across 32 input channels. It is very accurate and provides five modes of operation. But what logic analyzer you want to buy completely depends upon your choice and requirements.
