# 1120A Agilent Active Probe Used

**Features:**

-   Bandwidth: DC-coupled; DC to >500 MHz; AC-coupled: <1.5 kHz to >500 MHz 
-   Pulse response: Rise time <0.75ns; Perturbation: <+10% measured with 1 GHz sampler
-   Gain: Active probe 1:1 +/-5%
-   Dynamic range: +0.5V with +5V offset (DC)
-   DC offset Noise: approx. 2.5mV 
-   Input RC: 100k shunt capacitance is <3 pf at 100 MHz; with 10:1 or 100:1 dividers 
-   Shunt capacitance is <1pf at 100 MHz 
-   Maximum input: +80V

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.
