The Oscilloscope Probe 1:1-1:10 - HP-3250I is a 1:1-1:10 selectable passive high impedance oscilloscope probe with 250 MHz bandwidth (1:10) designed and calibrated for use on oscilloscopes having an input impedance of 1 MOhm shunted by 20 pF. However, it may be compensated for use with an oscilloscope having an input capacitance of 10 to 30 pF.

The oscilloscope probe incorporates a two position slide switch in the head which selects the attenuation of X1 or X10.

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