Input Impedance Profile: RCRC architecture is the best choice for signals with low source impedance and RC architecture is the best choice for measuring signals that transition to low power modes because it has lower loading.
Probe noise listed is the most common setup. Probe noise can vary with multiple factors such as attenuation ratio, probe head, and probe mode.
Measure differential, single-ended, and common mode signals.
Auto selected based on volts/division (all modes).
