Logic analyzers are better alternatives to oscilloscopes—they can accurately measure data on a bus and develop relationships. Sometimes, when the circuit demands testing for different lines, the best logic analyzer can help you decode and present meaningful information that will make your design process a breeze. Also, in the parametric stage of circuitry, a logic analyzer will allow you to time the signals while triggering patterns simultaneously, making it the most appropriate tool, by far!
Most logic analyzers come with two scopes of functions—timing and stating. But since these devices are not made equal, knowing whether to choose a timing analyzer over a stating analyzer or a device that combines both can be an uphill task.
Your being here is a justification that you need help with the overall choosing process. Congratulations! You’re on the right path to landing the best analyzer that meets all the needs you desire. Stay through to the end as we’re also going to reveal our final verdict based on each product’s features, pros, and cons that rack our list.

Factors to Consider When Purchasing a Logic Analyzer
With various logic analyzers in the market, it can be challenging to choose which one is the best and suits your requirements. While buying a logic analyzer, keep in mind these factors to avoid any confusion. They include:
- Type of logic analyzer
Logic analyzers come in 3 different types, including portable, modular, and PC-based. For portable logic analyzers, consist of a screen with various buttons and knobs. They don’t require a separate computer. Modular logic analyzers are rack-mounted. They need a different computer with specific software for collecting and analyzing data. PC- based are similar to modular analyzers as they require a host computer to analyze the visualization of waveforms.
- Number of channels
You need to check the number of channels available on the logic analyzer. The number of channels varies from 8, 16, 32, and more. A large number of input channels enables you to debug parallel communication busses. Also, consider the sample rate as it determines the amount of time your analyzer can effectively measure different readings from captured signals.
- Easy to use and portable
When buying a logic analyzer, choose one that can operate without an engineer’s help. Also, select an analyzer compact and lightweight to allow you to carry it to remote areas.
- Check sample rate and bandwidth.
You should check the sample rate and bandwidth of the logic analyzer before purchasing one. If the device’s sample rate is operating faster than bandwidth, it can be challenging to record the signal. Make sure you choose a logic analyzer with both a faster sample rate and bandwidth.
- Software features
Before purchasing a logic analyzer, check the software features and how each component is compatible with the analyzer to ensure accurate signal measurement.
- Data compression function
You should consider a model with a compression function since it can record the signals for hours without interruption. For devices without compression function, it can only record up to 5 seconds at 200Ms/s sampling rates.
HitLego is perfect when looking for a starting device. It’s packed in a compatible body with highly-operational functions, making it ideal for hobbyists. It also works perfectly for small projects that do not include complex decoding and testing.
QiXin racks the top list when looking for a highly portable device that supports multiple functions that include complex projects. It offers nothing short of value for bucks when looking for the best Logic Analyzer for Adruino FPGA and ARM circuitry. However, you’re not limited to choice since the Keeyees has you covered as an alternative. This device, too, performs the same functions as the QiXin, only that you’ll have to part with extra cash when buying. Otherwise, the two devices are our best recommendation anytime.
