SPICE Models
If damped wire accessories or longer mid-BW resistors (for solder-in probe heads)
are used, they can be modeled by adding an RLC model in front of the appropriate
probe head model and zeroing out the damping resistor in the probe head model.
There is one SPICE schematic for the differential probe heads and one SPICE
schematic for the single-ended probe heads. The schematics have parameterized
R, L, and C values that are given in the SPICE deck for the specific probe head.
Additionally, an input impedance plot is given that shows the matching of the
measured data to the modeled data. Matching is generally very good up to the
specified BW of the probe head with the 7 GHz probe amp.
