DP3000 High Voltage Differential Probe

The DP3000 is a robust high voltage differential probe from Micsig's DP Series high voltage probe lineup, designed for demanding differential voltage measurement and high voltage circuit testing applications up to 3000V. As a versatile oscilloscope differential probe with multi-brand oscilloscope compatible performance via standard BNC output interface, this Micsig oscilloscope probe provides dual range switching between 100X attenuation ratio and 1000X attenuation ratio, supporting 300V max input differential voltage and 3000V max input differential voltage respectively. Featuring a 3.5ns maximum rise time across its 100MHz bandwidth, the DP3000 delivers reliable amplitude frequency flatness with excellent differential signal precision for high-voltage power electronics measurements. The high impedance low capacitance design with 30MΩ differential input impedance and only 0.8pF differential input capacitance achieves significant signal loading effect minimization, preserving circuit integrity during critical high-voltage measurements. With strong high CMRR measurement capability including 80dB DC CMRR, 60dB CMRR at 100kHz, and 26dB CMRR at 100MHz, this probe serves as a dependable floating measurement solution for high common mode voltage testing in industrial power systems. Low noise floor measurement performance with 100mVrms noise at 100X and 500mVrms noise at 1000X provides solid small signal detection sensitivity even at high attenuation levels. The integrated 5MHz bandwidth limit function enables high frequency noise filtering and high frequency noise suppression, optimized for FET switching frequency measurement and power supply testing applications. Practical operational features include one-button zero calibration, overload alarm function, and range power-off memory for improved testing workflow efficiency. Type-C data communication supports command based programming for seamless automated testing system integration. With 1MΩ output impedance, 3.2ns delay time at 1000X, and optimized signal to noise ratio improvement, the DP3000 delivers consistent waveform clarity enhancement and measurement accuracy improvement for high-voltage floating measurements, industrial power converter design, and medium-voltage power electronics development.
