Frequently Asked Questions:

Question: What does a logic analyzer measure?

Answer: Logic analyzers record the sequence of digital logic signals and display them over time. They do not measure analog voltage characteristics, but digital signals with fixed defined states, for example High/Low, 0/1 (CMOS, TTL or other levels as well as undefined states and Z/high impedance state of a digital line). Since digital signals often occur in groups such as buses, logic analyzers typically have multiple parallel inputs, typically 8, 16, and more. Decoding and analyzing protocols is another essential function of logic analyzers, which are used for testing, analysis and troubleshooting of digital circuits, data transmission interfaces and data buses. If, on the other hand, the qualitative course of a signal is of interest in detail, oscilloscopes are used.

Question: What is "mixed-signal logic analysis" of the Saleae logic analyzers?

Answer: Common logic analyzers have digital-only channels (see above). Saleae logic analyzers are mixed-signal devices. Their channels are freely switchable for digital (logic analyzer) or analog acquisition ("simple oscilloscope"). Thus, only one of these convenient, compact logic analyzers is needed to analyze mixed circuits. The max. sample rate of Saleae Pro instruments for digital signals is 500 MS/s (4 channels) or 100 MS/s (16 channels), the max. analog sample rate is 50 MS/s (3 channels) or 6.25 MS/s (16 channels) with 12 bit resolution.

Question: Saleae mixed-signal logic analyzer or MSO - when do I use which instrument?

Answer: It depends on where the focus of your analysis is. With Saleae logic analyzers, the application focus is on logic functions:

  • Common logic levels and protocols supported.
  • Ideal for digital logic analysis.
  • Ideal for analysis of circuits where, for example, digital signals from a microcontroller interact with standard analog signals in the range 0...5 V or -10...+10 V.
  • If flexibility of the channels is required: With the MSO the channels are fixed (for example 2 or 4 analog inputs with BNC and 8 or 16 logic channels), with the Saleae devices the 8 or 16 channels are freely switchable.

The Saleae devices are less suitable, if the oscilloscope function is in the foreground. Then you should choose a MSO:

  • Detailed analysis of signal integrity.
  • Analysis of analog signals with high bandwidth.
  • Display of small voltage (less than 10 mVpeak-to-peak) at high resolution.
  • Range of the analog signal to be measured is outside the -10...+10 V range of the Logic Pro family.
  • In addition, many oscilloscopes offer extensive functions such as math, statistics, automatic measurement and trigger functions as standard.

Question: Are the logic clips included with Saleae logic analyzers?

Answer: Yes, the test leads and logic clips are included, as well as a carrying case, USB 3.0 cable, and quick start guide. Software (for Windows, Mac and Linux) and detailed manual are available via download from the manufacturer's website. Logic clips and test lead sets are also available as accessories, for example as spare parts.

Question: Which operating systems does the Saleae software support?

Answer: Currently (as of April 2021) supported are Windows 8 and 10, Mac OSX 10.14 Mojave+ and Linux Ubuntu 16.04+ 64 bit et al. Our support team will be happy to inform you about the current status.
