Company Overview

Micsig (麦科信) is a Chinese oscilloscope and probe manufacturer headquartered in Shenzhen, best known for its tablet-style oscilloscopes and isolated-channel instruments. The company pairs modern UI design with practical isolation technology for power-electronics measurement, offering an attractive route to multi-channel floating measurements at accessible prices.

History

Micsig was founded by experienced instrument engineers who saw two underserved needs: portable oscilloscopes with tablet-grade usability, and true channel-to-channel isolation for power-electronics and EMC work. Its tablet oscilloscopes created a new product category, and its isolated portable series (TO series) brought four-channel galvanic isolation to engineers testing inverters, drives and switched-mode supplies in the field.

Strengths

The brand combines hardware isolation with software polish: capacitive touch operation, long battery life and compact form factor make field diagnosis genuinely practical. The isolation architecture withstands significant common-mode voltages, and the probe range (high-voltage differential, current probes) is matched to the instruments. Firmware updates and technical support are responsive.
