The Logic 4 is a logic analyzer with a well thought out and user friendly PC software which makes digital measurement very fun. Just plug in via USB and go.
The digital capture rate is 12 MSa/s on every channel. Because of the streaming and the USB 3 interface to the PC, the memory depth is unlimited. The logics also show analog signals because all digital channels are captured simultaneously with the A/D converter. The analog capturing is with 6 MS/s slower than the digital capturing, but it provides an insight in analog signal behaviour. The bandwidth of the analog capturing is 600 kHz (-3db). But the signal is already attenuated at this point.
The Saleae logic analyzer are perfect for the mobile use because of the hand pocket size.

As of October 2022, Saleae has released a new hardware revision of the analysers, starting with Logic Pro 8, which requires the latest version of Logic 2 software. This newer revision of the hardware cannot work with the old Logic 1.x software.
