DP1503 300MHz High Voltage Differential Probe

The DP1503 is a high-performance 300MHz high voltage probe from Micsig's DP Series differential probe family, engineered for precision differential voltage measurement and high speed signal accuracy in demanding power electronics applications. As a professional oscilloscope differential probe with wide brand oscilloscope compatibility via standard BNC output interface, this Micsig high voltage probe offers dual range switching between 50X attenuation ratio and 500X attenuation ratio, supporting 150V max input differential voltage and 1500V max input differential voltage respectively. Featuring an exceptional 1.2ns typical rise time and 1.5ns maximum rise time, the DP1503 delivers fast rise time measurement capability with excellent amplitude frequency flatness across its full 300MHz bandwidth. The high impedance low capacitance design with 13.2MΩ differential input impedance and only 1pF differential input capacitance provides significant signal loading effect reduction, ensuring minimal circuit disturbance during high frequency signal measurement. With robust high common mode rejection performance including 80dB DC CMRR, 60dB CMRR at 100kHz, and 26dB CMRR at 100MHz, this probe serves as a reliable floating measurement solution for high common mode voltage testing scenarios. Low noise floor measurement performance with 180mVrms noise at 50X and 205mVrms noise at 500X delivers outstanding small signal detection sensitivity. The integrated 5MHz bandwidth limit function enables high frequency noise filtering and high frequency noise suppression, making it ideal for FET switching frequency testing and power supply testing. Convenient operational features include one-button zero calibration, overload alarm function, and range power-off memory for enhanced testing efficiency. Type-C data communication supports command based programming for seamless automated testing system integration. With 50Ω output impedance and optimized signal to noise ratio optimization, the DP1503 delivers superior waveform clarity improvement for high-voltage floating measurements, power converter design, and high-frequency power electronics development.
