The P6015 High Voltage Probe provides X1000 attenuation for oscilloscope measurements up to 40 kV peak. Voltage or duty cycle derating is necessary for RF voltages at frequencies over 100 kHz, or in temperatures above 25?C. The probe can be compensated for instruments with nominal input capacitance of 12 pF to 47 pF. Input Resistance: 100 Mohm Probe Capacitance: approx. 3 pF Probe Risetime: approx. 4 ns
