What type of oscilloscope probes are typically used for amplitude signals?

The correct type of oscilloscope probes used for amplitude signals are passive probes. Passive probes are the most commonly used for measuring amplitude signals in electronic circuits, especially for general-purpose applications. They typically consist of a resistive divider network and do not have any amplification capabilities, making them ideal for capturing standard signal amplitudes without introducing significant loading effects or altering the signal characteristics.

Passive probes are versatile, cost-effective, and sufficient for a wide variety of situations where high frequency and low capacitance are not critical requirements. They effectively maintain a balance of performance for measuring voltage levels in signals, making them highly applicable for general testing.

In contrast, active probes incorporate amplification, which can be beneficial for high-frequency signals or when needing to measure very low-level signals without degrading the signal quality. However, they are typically used in more specialized scenarios rather than for routine amplitude measurements.

The other choices do not align with established oscilloscope probe terminology or function: "Insinuation probes" and "oscillation probes" are not recognized types of oscilloscope probes in this context. Thus, for typical amplitude signal applications, passive probes remain the standard choice.
