The GDP-025 25 MHz High Voltage Differential Probe provides 25M Hz bandwidth enabling users to safely make high-voltage measurements on floating circuit test. GDP series high-voltage differential probe converts floating signals to low-voltage ground referenced signals that can be displayed safely and easily on any ground referenced oscilloscope. The GDP-025 differential probe offer user selectable attenuation settings that make it highly versatile, allowing it to be used for a broad range of applications. The probe comes with probe tip accessories for use with both small or large components in tight places. Also provide over-range indicator which alerts the user when the probe input exceeds the dynamic range of the probe. +/-2 Percent accuracy. greater than or equal to +/-7V Output. 50ohm Output impedance. External 9VDC power supply.
