DP3003 300MHz High Voltage Differential Probe

The DP3003 is a premium 300MHz differential probe from Micsig's DP Series high voltage probe collection, engineered for high-voltage differential voltage measurement and fast transient measurement in advanced power electronics testing applications. As a high-performance high voltage differential probe with universal oscilloscope compatibility via BNC standard interface, this Micsig oscilloscope probe features dual voltage range selection between 100X attenuation ratio and 1000X attenuation ratio, supporting 300V max input differential voltage and 3000V max input differential voltage respectively. Boasting an impressive 1.2ns typical rise time and 1.5ns maximum rise time, the DP3003 delivers exceptional high speed signal precision with excellent frequency response flatness across its full 300MHz bandwidth. The low loading effect design with 30MΩ differential input impedance and only 0.8pF differential input capacitance achieves significant circuit loading minimization, ensuring accurate measurements without disturbing high-voltage circuits under test. With robust common mode rejection performance including 80dB DC CMRR, 60dB CMRR at 100kHz, and 26dB CMRR at 100MHz, this probe provides reliable non-grounded measurement capability for high common mode measurement scenarios. The ultra low noise floor performance with 400mVrms noise at 100X and 480mVrms noise at 1000X maintains usable weak signal detection capability even at maximum attenuation settings. The integrated bandwidth limiting function enables high frequency interference filtering and high frequency noise reduction, optimized for power device switching test and high frequency signal analysis. Convenient operational features include auto zero calibration, overload warning function, and range memory function for streamlined testing efficiency. Type-C communication port enables programmable test probe functionality for seamless automated test system integration. With 50Ω output impedance and optimized signal noise ratio enhancement, the DP3003 delivers superior waveform definition improvement for high-voltage floating measurements, wide-bandgap semiconductor testing, and high-frequency power converter development.
