MEASTEK MDP4700B High Voltage Differential Probe 7000V 100MHz Oscilloscope Probe
Key Features:
1. This series of high-voltage differential probes adopts an integrated design without any buttons, with a longer service life and a more user-friendly design;
2. The probe is equipped with a standard BNC output interface and can be used with any manufacturer's oscilloscope. (The input impedance of the oscilloscope is required to be set to 1MΩ; when 50Ω is selected, the attenuation factor will be doubled) to measure the waveform of the circuit under test;
3. The high-voltage differential probe has an automatic save function to prevent users from repeating operations after power failure.
4. The probe has good common-mode noise suppression capability, and the input end has a higher input impedance and lower capacitance, which can accurately and quickly measure differential voltage signals.
5. It can be widely used in the research and development, debugging or maintenance of switching power supplies, inverter electronic ballasts, inverter home appliances and other electrical power devices.
