The DP6000B Series High-Voltage Differential Probe is a high-voltage differential probe with floating measurement capability. Its maximum bandwidth reaches up to 300MHz, which meets the needs of most test systems. A variety of measurement ranges are available, and its differential measurement voltage range satisfies the requirements of most test circuits. If an offset phenomenon occurs after long-term use of the probe, users can enter the test mode, adjust the offset, and achieve zero adjustment; equipped with electronic touch-sensitive buttons, it has a longer service life. It features a selectable 5MHz bandwidth limitation function; the 5MHz frequency bandwidth meets the measurement needs of FETs' switching frequency in most switching power supplies and can filter out higher-frequency noise and interference. It is equipped with an audio-visual alarm function, and the sound alarm can be manually turned off, featuring a more user-friendly design. The USB power supply interface enables more convenient and flexible use. The probe is equipped with a standard BNC output interface and can be used with oscilloscopes from any manufacturer (requiring the oscilloscope's input impedance to be set to 1MΩ; when 50Ω is selected, the attenuation ratio will be doubled) to measure the waveform of the tested circuit. The auto-save function prevents users from repeated operations after power failure. The probe has excellent common-mode noise rejection capability, and the input end has high input impedance and low capacitance, enabling accurate and high-speed measurement of differential voltage signals. It can be widely used in the R&D, debugging or maintenance of switching power supplies, frequency converters, electronic ballasts, variable-frequency home appliances and other electrical power devices.
