The capabilities of a logic analyzer differ from oscilloscope capabilities. The most obvious difference between these of the two instruments is the number of channels (inputs). Oscilloscopes have up to four signal inputs, logic analyzers have from 34 to 136 channels, where each channel passes one digital signal.
A logic analyzer measures and analyzes signals in a different way than an oscilloscope. A logic analyzer does not measure the analog signal in detail, but instead determines the threshold levels of the logic signal. When you connect a logic analyzer to a digital circuit, you are only dealing with the logic state of the signal.
