DP3000 - 100MHz high voltage differential probe

Description

The differential probe based on advanced SigOFIT technology by Micsig is a modern tool featuring very low noise levels, excellent amplitude and frequency characteristics at high voltages, and leading common-mode signal rejection capabilities. These features allow users to easily perform high-frequency and high-voltage signal testing. The probe has a bandwidth limitation to 5 MHz, which effectively eliminates high-frequency interference during switching frequency measurements in most switch-mode power supplies. Additionally, the zero-point calibration function enables quick and easy zeroing of the probe. It also supports dual measurement ranges, improving the signal-to-noise ratio and allowing adaptation to a wide variety of testing requirements. A standard BNC connector ensures compatibility with virtually any oscilloscope, while USB power supply eliminates the need for additional power sources.

Additional features such as an overvoltage alarm with flashing LED and buzzer alert enable the user to quickly respond to potential issues. The DP probe also stands out with its compact and sleek design, significantly smaller than traditional differential probes. Furthermore, it offers excellent bandwidth flatness and amplitude fluctuation below 0.5 dB within half the bandwidth range, even at high frequencies, ensuring high measurement precision. High input impedance and low input capacitance minimize loading effects, greatly improving the accuracy of differential signal measurements.

The probe is highly versatile and can be used for AC voltage measurements, high-voltage insulation testing, switch-mode power supply design, and power converter development. It is a flexible and practical tool suitable for both electronics labs and industrial environments.
