Plug And Debug With ScanaQuad SQ200 Logic Analyzer and Signal Generator

The ScanaQuad 200 by Ikalogic is a high-performance 4-channel logic analyzer and digital pattern generator. It is designed to be the best companion of a hobbyist when working on serial protocols like UART, SPI, I2C, 1-Wire, USB, I2S, CAN, LIN, RS232, RS485, and more. With the ScanaQuad 200 Logic Analyzer, you can capture signals, you can play them back, and you can even program genuine test signals using ScanaStudio software and generate them.

Being able to capture and generate logic patterns simultaneously with a single tool, it is quite useful while testing and debugging logic signals. Now, you can achieve these same features with modern function generators and oscilloscopes. But unfortunately, these devices usually carries a price that puts them out of reach of those who only need them occasionally. So, the ScanaQuad is the best and the cheapest solution for hobbyists.
The sampling frequency of the ScanaQuad SQ200 is minimum 10KHz and maximum 200MHz, with 50MHz of input bandwidth. It has a stunning sampling resolution of ±5ns only. SQ200 is capable of handling ±15V input signal in continuous signal mode and the ±50V input signal in 10ms pulse mode.  The function of the four ports of this logic analyzer can be defined by the user with the help of the ScanaStudio software. The user can also control pulse width and duty cycle of the output signal. Complex data sequences may be programmed to simulate several communication protocols using JavaScript. ScanaQuad SQ200 comes with predefined sets of various protocol decoders. This logic analyzer even allows users to create their own protocol decoders.
The following table shows the input characteristics of SQ200:

Input resistance (Fixed) 1MΩ
