Digital channel signal fidelity: Probe impedance and grounding

When using the mixed-signal oscilloscope you may encounter problems that are
related to probing. These problems fall into two categories: probe loading and
probe grounding. Probe loading problems generally affect the device under test,
while probe grounding problems affect the accuracy of the data to the
measurement instrument. The design of the probes minimizes the first problem,
while the second is easily addressed by good probing practices.

Input Impedance

The logic probes are passive probes, which offer high input impedance and high
bandwidths. They usually provide some attenuation of the signal to the
oscilloscope, typically 20 dB.
