Overview
The Testec TT-MX 312 is a professional-grade passive oscilloscope probe for accurate signal measurement in mid-frequency applications. Part of Testec's MX series, this probe offers switchable x1 (10MHz) and x10 (250MHz) attenuation modes, making it ideal for engineers working with low-voltage precision circuits and higher-voltage systems up to 400V CAT II. Its adjustable compensation range (8–25pF) ensures compatibility with most oscilloscope inputs, while the 1.2m shielded cable minimises noise interference.
Compared to the lower-bandwidth TT-LX 312 (150MHz) and the higher-spec TT-HX 312 (350MHz), the TT-MX 312 strikes an optimal balance for general-purpose debugging. Key safety features include 1500V transient overvoltage protection and full compliance with EN 61010-031 safety standards. The ergonomic 5mm tip with spring-loaded accessories enables secure connections to SMD components, while the CE-certified design meets rigorous EU EMC and RoHS III directives.
For engineers requiring reliable performance without active probe complexity, the TT-MX 312 delivers exceptional value through its durable construction, ±2% DC accuracy, and Pollution Degree 2 certification for stable operation in industrial environments.
