The Tektronix TDP1000 is a high-voltage differential probe designed for precise measurement of differential signals in high-speed digital, power electronics, and automotive applications. With 1 GHz bandwidth, selectable attenuation (10x, 50x, 100x), and maximum differential voltage ratings up to ±1000 V, it delivers accurate characterization of switching waveforms, gate drive signals, and high-speed interconnects. The probe’s high input impedance (1 MΩ || 1.5 pF) minimizes circuit loading, while strong common-mode rejection (100:1 at 100 MHz, 30:1 at 1 GHz) ensures measurement integrity in noisy environments.
