LeCroy PP021-2 - 2 Pack of 500 MHz Passive Probe, 2.5mm, 10:1, 10 MOhm

Passive probes are the standard probe provided with most oscilloscopes. Typical passive probes provide a 10:1 attenuation and feature a high input resistance of 10 MΩ. This high input resistance means that passive probes are the ideal tool for low frequency signals since circuit loading at these frequencies is minimized. Passive probes are designed to handle voltages of at least 400V, some as high as 600V. Teledyne LeCroy passive probes feature an attenuation sense pin which tells the oscilloscope to scale the waveforms automatically requiring no user input.

Each passive probe is recommended for a certain oscilloscope, using the right passive probe with the right oscilloscope means that the probe will be properly compensated across the entire bandwidth. Using probes with a different oscilloscope will only let you compensate for low frequencies.

The Teledyne LeCroy PP021 is a passive high impedance voltage oscilloscope probe designed and calibrated for use with general purpose oscilloscopes having an input impedance of 1 MΩ and can be compensated for use with instruments having an input capacitance between 14 to 25 pF. It is compatible with oscilloscopes that automatically detect probe attenuation and adjust their readout accordingly.
