Sonic 4000 RF
About Sonic 4000 RF
The Sonic 4000 RF active probe offers best-in-class performance and is easy to use to make
in-circuit measurements. With the Sonic 4000 RF's 220 Hz to > 4 GHz bandwidth, high input im-
pedance, low noise and > ±8 V dynamic range makes it the ideal probe to use spectrum, network,
RF analyzers or other 50 Ω measurement system. The input capacitance of < 0.6 pF parallel 2 MΩ
between probe tip and probe reference (1 MΩ to the oscilloscope ground) provides the highest
impedance in its class to allow the probing of sensitive circuits without adversely loading the
circuit under test.
The high impedance probe tip reference connection is a key feature of the Sonic 4000 RF. Unlike
traditional single-ended, with their probe tip reference connected to earth ground that can dama-
ge the customer's circuit if it is accidentally connected to any non-ground test point, the Sonic
4000 RF probe tip reference impedance to earth ground is 1 MΩ. This feature allows for safe in-
circuit browsing of an energized circuit without the possibility for shorting the probe tip reference
connection directly to earth ground.

Loading Schematic
The Sonic 4000 RF active probe uses a PMK custom high speed FET input amplifier with active
cladding wave compensation to provide a superior high frequency response as well as a low noise
and low distortion to accurately measure the customer signals. The output signal of the probe has
no DC component, so it can be connected to DC sensitive measurement equipment.
