The Agilent 1120A is a 1:1 active voltage probe which provides low input capacitance, high input impedance, high current gain and wide bandwidth. The probe has a probe-tip impedance of 100 kilohms shunted by less than 3 picofarads capacitance and also features very low drift and noise. When used with the voltage-divider tips, the input shunt capacitance is less than 1 picofarad.
The Agilent 1120A permits the operator to test high-frequency circuits without significant loading effects. High input impedance is maintained by a field-effect transistor (FET) circuit. Power for the probe is provided by Agilent HP Osciloscopes with probe power or with a probe power option, oscilloscope plug-in units with probe power, or Model 1816A remote sampler.
When operated with instruments having no probe power, the Model 1122A Probe Power Supply must be used as a power source.
