logic analyzer

Overview

The beggar’s version of the isolation logic analyzer
uses the domestic digital isolation chip CA-IS3740HW for isolation. Although it cannot use analog channels, it greatly improves the security of the equipment. After the
test
logic analyzer was welded, I did not have a suitable instrument under test. In order to verify the effect of the logic analyzer, I tested myself. The effect is as follows: two wires, one ground wire, and one connected to the CLK of the test chip. pin. (Please ignore the power chip. I bought the ADJ version of the power chip, so I can only add a feedback network by myself). It can be seen that the effect of the logic analyzer is still good, and you can have fun playing with it.
