Overview
The Testec TT-CC 990 is a professional-grade AC/DC current probe designed for precise measurement of both alternating and direct currents in high-frequency applications. Part of the TT-CC series, this probe delivers a bandwidth of DC to 1.5 MHz, making it ideal for analysing fast transient currents in power electronics, motor drives, and switch-mode power supplies.
With two switchable sensitivity ranges (1 V/A and 100 mV/A), the TT-CC 990 measures currents from 4 A to 40 A peak, ensuring versatility across low- and high-current circuits. Its split-core design allows non-invasive clamping onto conductors up to 10.3 mm in diameter, eliminating the need to break circuits during testing. The probe is CAT III 300 V / CAT II 600 V rated, providing robust protection in industrial environments.
Included with the probe are a BNC-to-BNC coaxial cable, a BNC-to-banana plug adapter, and a 9 V alkaline battery or AC power supply for extended use. Engineers will appreciate its 0.23 µs rise time and ±3% DC accuracy, enabling detailed analysis of current waveforms in demanding applications like inverter testing or transient load analysis.
As part of the TT-CC series, the 990 model stands out for its ultra-high bandwidth, outperforming competitors like the Hioki CT6846A (100 kHz) and Tektronix TCP0030A (120 MHz but lower current capacity). For engineers requiring reliable, high-frequency current measurements without compromising safety or precision, the TT-CC 990 is an indispensable tool.
The TT-CC family of AC/DC current probes enable oscilloscope instruments to display AC, DC, and AC+DC current measurements up to 100 amps peak (TT-CC-220) and frequencies up to 1.5 MHz (TT-CC-990). Using supplied BNC to banana plug adapter the current probes will work with most modern Digital Multimeters (DMM).
The Current Probe is powered from an internal 9V Alkaline battery or an external AC Adapter (included)
