Keysight-Agilent 1120A/001

The 1120A Active Probe is a 500MHz probe for probing high source impedances 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. The 50-ohm output provides the optimum impedance match and measurement accuracy for oscilloscopes, spectrum analyzers, counters, and network analyzers with 50-ohm inputs. Power is supplied by instruments with probe power jacks or the 1122A probe power supply.
