Input Impedance
The E5382A probes have an input impedance which varies with frequency, and
depends on which accessories are being used. The following schematic shows
the circuit model for the input impedance of the probe when using the ground
extender clip. This model is a simplified equivalent load of the measured input
impedance seen by the target.
