The Testec TT-SI 7005 and 7002 active differential probes enable safe, accurate voltage measurements between two non-ground-referenced points in electronic circuits - critical for power electronics, motor drives, and inverter applications. These IEC 61010-031-certified tools feature:
Key technical advantages: The 7005 model (60MHz bandwidth @ x10 attenuation) excels in high-frequency applications like switch-mode power supply analysis, while the 7002 handles higher voltages (±700V DC+AC peak) for industrial equipment testing. Their differential measurement capability eliminates ground loop errors common in single-ended probes, essential when working with floating systems.
Unique attenuation flexibility: The 7005's x1/x5/x10 and 7002's x20/x50/x200 ranges let engineers optimise signal resolution while maintaining input protection. The auto-scaling compensation (1MΩ/50Ω input compatibility) ensures accurate vertical scaling without manual calculations - a time-saving benefit when analysing complex waveforms.
With 80dB CMRR at 60Hz, these probes effectively reject common-mode noise in electrically noisy environments. The included silicone-insulated test leads and CAT III safety rating make them ideal for working on three-phase systems or variable frequency drives where isolation is critical.
