The Probe 1:100 - HP-9258 is a low-input capacitance high voltage 1:100 oscilloscope probe with a bandwidth of 250 MHz designed and calibrated for use on scopes having an input impedance of 1 MOhm shunted by 20 pF. However, it may be compensated for use with oscilloscopes having an input capacitance of 10 - 35 pF.

The modular construction facilitates simple field replacement of the major parts.
