TESTEC TT-SI 8000 Series Active Differential Probes

Overview

The Testec TT-SI 8000 Series Active Differential Probe enables precise measurement of voltage differences between two non-grounded points, critical for analysing high-voltage circuits in power electronics, motor drives, and switch-mode power supplies. With bandwidths up to 200MHz and selectable attenuation ratios (e.g., 1:10/1:100 or 1:100/1:1000), it ensures minimal signal distortion while handling differential voltages up to 7000V (DC + peak AC).

Key features include a high common-mode rejection ratio (CMRR >80dB at DC), which eliminates noise interference in electrically noisy environments. Compliant with IEC 61010-031:2015 safety standards, it supports CAT III 600V and CAT II 1000V applications, providing robust protection for users and equipment. The integrated overrange alarm (audible and visual) prevents damage during voltage spikes, while USB-powered operation enhances portability.

Engineers benefit from its low input capacitance (2pF differential), reduced circuit loading, and compatibility with oscilloscopes from all major manufacturers. Included are accessories, such as insulated BNC cables, grabbers, and alligator clips, as well as a streamlined setup for diverse measurement scenarios. The TT-SI 8000 Series combines safety, precision, and versatility for professionals requiring reliability in high-voltage environments.
