Input impedanceThe input impedance of a PicoScope is the impedance it presents to the oscilloscope probe, if one is used, or otherwise directly to the device under test. It is typically 1 MΩ in parallel with 10 to 15 pF. Some PicoScopes allow their their inputs to be individually switched to 50 Ω impedance, to allow proper termination of 50 Ω cables and sources.
