Teledyne LeCroy PP005A - 10:1 500 MHz 10 MOhms Passive Probe

The PP005A is a high impedance passive probe with a range of probing accessories. The micro-fine tip of all PP005A probes is spring-loaded, reducing the chance of "skipping" the circuit once contact is established. Mechanical pressure is therefore reduced and probe life is enhanced. The micro-fine tip contributes to contact stability, in addition to making it easier to reach tightly placed circuitry.

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.
