T&M SSDN/SDN Coaxial High-Frequency Precision Shunts for Double Pulse

Model：T&M SSDN/SDN Country of Origin：USA

Category：Non-inductive coaxial shunt

Overview：

T&M's CRV high-frequency wideband current shunts are the industry's leading low-inductance, high-speed, wideband current shunts, with resistance values ranging from 0.5 Ω to 10 µΩ and a frequency range from DC to 2 GHz. They can measure pulse currents as fast as the picosecond (ps) level, with resistance accuracy options of 4%, 2%, 1%, and 0.2%.

Functions & Configuration

T&M's CRV high-frequency wideband current shunts are the industry leader in low-inductance, high-speed, wideband current sensing, with resistance values from 0.5 Ω down to 10 µΩ, frequency coverage from DC to 2 GHz, pulse current measurement down to the picosecond (ps) range, and resistance tolerances selectable from 4%, 2%, 1% to 0.2%. These CRV shunts are primarily used in military and high-end industrial applications, including current measurement in missile launch systems, space shuttles, satellite communications, spacecraft, warships, nuclear submarines, and other advanced equipment.

The CRV high-frequency wideband shunt family comprises 29 series. Dimensions, power ratings, and the available resistance and bandwidth ranges for each series are shown below:
