P6149
The Tektronix P6149 is a 10x voltage probe with a specified -3dB point of 50 MHz. The impedance at the tip is 10 megohms in parallel with 15.5 picofarads. The probe connects to the oscilloscope with a BNC connector, and the compensation range is 20 pF to 62 pF. The maximum input voltage is 500 V at DC, decreasing to about 25 V at 50 MHz.
