Micsig DP3005 - 500MHz High Voltage Differential Probe

Description

The differential probe based on Micsig’s advanced SigOFIT technology is a modern tool characterized by very low noise levels, excellent amplitude and frequency characteristics at high voltages, and superior common-mode signal rejection. These features allow users to easily test high-frequency and high-voltage signals. Additionally, the zero-point calibration function enables instant zeroing of the probe. The probe also offers dual measurement range capability, which improves the signal-to-noise ratio and allows it to adapt to various testing requirements. A standard BNC connector ensures compatibility with any oscilloscope, and power supplied via USB eliminates the need for external power sources.

Additional features, such as an overvoltage alarm with a flashing LED and a buzzer warning when the range is exceeded, allow the user to respond quickly to potential issues. The DP probe also features a compact and aesthetically pleasing design, significantly smaller than traditional differential probes. Furthermore, it provides excellent bandwidth uniformity, with amplitude fluctuation below 0.5 dB across half the bandwidth—even at high frequencies—ensuring high measurement accuracy. High input impedance and low capacitance minimize loading effects, which significantly improves differential signal measurement accuracy.

The probe can be widely used for AC voltage measurements, high-voltage insulation testing, switching power supply design, and power converter diagnostics. It is a versatile and flexible tool, useful both in electronics workshops and industrial environments.
