Keysight / Agilent 1123A Overview

The 1123A Active Probe is used for probing high source impedances at high frequencies. The probe should be used to apply input signals to the 1802A 100MHz plug-in. This X1 active probe has very low drift and noise and provides an input RC of 100 kohms and only 3.5 pF. Bandwidth: DC to > 220MHz (3 dB down) Gain is adjustable to X1 into 50-ohm load Output of ? 0.5 V peak Maximum input of ? 50 V (DC + peak AC) Output impedance of 50-ohms
