T&M SDN-001 high-frequency non-inductive coaxial shunt 0.001 Ω high-precision resistor current probe 2 watt

T&M CVR high-frequency non-inductive resistor, designed for monitoring pulse generator systems, extremely high peak power and current input generated by steady-state current loads, and transient current monitoring. In recent years, with the rapid development of power semiconductors and wide-bandgap devices, evaluation of device dynamic performance (double-pulse) requires high-precision capture of current waveforms during overall turn-on and turn-off transitions while minimizing the insertion loss of the probe itself.  

Key features:

• GHz measurement bandwidth, picosecond-level measurement delay;

• Patented technology, extremely low inductance;

• Monitors continuous signals (W) or high-energy pulses (J);

• 0.2% ultra-high resistance accuracy;

• Maximum power dissipation of 2–3 W per unit;

• Universal BNC connector
