I、 Overview
1、 Basic knowledge
Logic analyzer is the instrument that collects and displays the digital signal from the
devices under test. It is mainly used for timing judgement an analysis. Unlike the oscilloscope
with many voltage grades, It has only two grades(Logic one and Logic zero). .After the
reference voltage is set, the logic analyzer could decide from the test signal that the signal
above the reference voltage is logic one, and the signal below is logic zero. The digital
waveform is formed with 1 and 0. Compared with the oscilloscope, when testing and
measuring the digital systems like MCU, ARM, FPGA and DSP, the logic analyzer could
provide better accuracy, much more data and more complicated measuring methods.
For example, if you are sampling a signal with the logic analyzer, the sample rate of
which is 1Mhz, and the reference voltage is set to 1.5V, the logic analyzer would compare the
current voltage with 1.5V. The signal above 1.5V would be high level(logic 1), and the signal
below 1.5V would be low level(logic 0). Thus we get a sample point, and then we could link
all these points(logic 1 and logic 0) to get a waveform, in which the user could see and analyze
the timing of the signal, logic errors and the relation between each other.
The figure below shows how the logic analyzer samples the signal:
