500MHz, 100Kohms <1 pF at 100MHz industrial
The HP 1120A Active Probe is a 500MHz probe for probing high source impedance at high frequencies. This 1:1 active probe provides a probe tip impedance of 100 Kohms shunted by approximately 3 pF at 100MHz. When used with the 10:1 or 100:1 divider tips, the shunt capacitance is <1 pF at 100MHz.
