DP1502 High Voltage Differential Probe

The DP1502 is a professional high voltage differential probe from Micsig's DP Series probe lineup, designed for precision differential voltage measurement and high voltage floating measurement applications. As a versatile oscilloscope probe compatible with most oscilloscope brands via standard BNC interface, this Micsig differential probe delivers 200MHz bandwidth with dual voltage range selection of 50X attenuation ratio and 500X attenuation ratio, supporting 150V max input differential voltage and 1500V max input differential voltage respectively. Featuring a 1.8ns typical rise time and 2.2ns maximum rise time, the DP1502 captures fast transients with exceptional amplitude frequency performance and differential signal accuracy. The high-resistance, low-capacitance design with 13.2MΩ input impedance and 1.8pF differential input capacitance minimizes signal loading effect reduction, ensuring accurate measurements without distorting the circuit under test. With high common mode rejection capability including 80dB DC CMRR, 60dB CMRR at 100kHz, and 26dB CMRR at 100MHz, this probe excels at common mode voltage measurement in noisy environments. Low noise floor performance with 50mVrms noise at 50X and 190mVrms noise at 500X provides excellent small signal measurement sensitivity. The integrated 5MHz bandwidth limit function enables high frequency noise filtering and high frequency noise suppression, ideal for FET switching frequency measurement in power supply testing applications. Practical features include one-button calibration with auto zero calibration, overload alarm protection, and range power-off memory for improved workflow efficiency. The Type-C interface probe supports command control and programming control probe functionality for automated testing systems. With 1MΩ output impedance and excellent signal to noise ratio improvement, the DP1502 delivers waveform clarity improvement and measurement accuracy enhancement for high voltage testing, power electronics design, and floating measurement scenarios.
