P6149
The Tektronix P6149 is a passive ×10 voltage probe with a specified -3 dB point of 50 MHz. The impedance at the tip is 10 MΩ in parallel with 15.5 pF.
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.
