The Sonic® 4000 active probe offers best-in-class performance and is easy to use to make in-circuit measurements. With the Sonic® 4000's DC to > 4GHz bandwidth, high input impedance, low noise and ± 8V dynamic range makes it the ideal probe to use with any oscilloscope or other 50Ω measurement system. Sonic® 4000's ± 12V input offset capability extends the input voltage range of the probe. The input capacitance of <0.6pF parallel 2MΩ between probe tip and probe reference (1MΩ 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 "PMK Probe Control software" provides the ability for the user to control the probe remotely
via a computer, and provides the user with a graphical user interface. The software is free of charge, and included with PMK’s 2ch and 4ch power supplies, PS-02 and PS-03, which are required to power the probe. The PS-02 and PS-03 power supplies have a USB interface as well as an optional LAN interface.
