DP701 - 150MHz high voltage differential probe

Description

The differential probe based on Micsig's advanced SigOFIT technology is a modern tool that is characterized by a very low noise level, excellent amplitude and frequency characteristics at high voltage and an advanced ability to reject common-mode signals. Thanks to these features, users can easily test high-frequency and voltage signals. The probe has a bandwidth limit of 5 MHz, which effectively eliminates high-frequency noise when measuring transistor switching frequencies in most switching power supplies. Additionally, the zero point calibration function allows you to zero the probe instantly. The probe also offers dual-range capability, improving signal-to-noise ratio and adapting to a variety of test requirements. The standard BNC connector allows operation with any oscilloscope, and the power supply from the USB port eliminates the need for additional power sources.

Additional features, such as an overvoltage alarm with a flashing LED and an out-of-range alarm, allow the user to quickly respond to possible problems. The DP probe also stands out for its compact and aesthetic design, much smaller than traditional differential probes. Moreover, it is characterized by excellent bandwidth uniformity, with amplitude fluctuations below 0.5 dB in the half-band range, even in the case of high frequencies, which guarantees high measurement precision. High input impedance and low capacitance minimize the loading effect, which greatly improves the accuracy of differential signal measurement.

The probe can be widely used for AC voltage measurements, high voltage insulation measurements, and the design of switching power supplies and power converters. It is a versatile and flexible tool useful both in an electronics workshop and in an industrial environment.
