The P6501 is a passive high impedance oscilloscope probe designed and calibrated for use with instruments with an input impedance of 1MΩ in parallel with 13pF. Furthermore, the probe can compensate for instruments with input capacitances ranging from 8 to 20 pF. The P6501 is compatible with oscilloscopes with automatic probe recognition. The oscilloscope can then automatically detect the probe attenuation ratio and adjust the display range.
