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.
