A brief comparison of the most commonly used high-impedance passive probes and active probes is as follows:
Active Probe vs Passive Probe
Low-resistance resistor divider probes have lower capacitive load (<1pf), higher bandwidth (>1.5GHz), and lower price, but the resistance load is very large, generally only 500ohm or 1Kohm, so it is only suitable for testing low sources Impedance circuits, or circuits that focus only on time parameter testing.
High-impedance passive probes with compensation are the most commonly used passive probes, and generally standard oscilloscope probes are such probes. The high-impedance passive probe with compensation has a high input resistance (generally more than 1Mohm), an adjustable compensation capacitor to match the input of the oscilloscope, and has a high dynamic range, which can test large-amplitude signals (tens of amplitudes). above), the price is also lower. But what is unknown is that the input capacitance is too large (generally more than 10pf) and the bandwidth is low (generally within 500MHz).
