Rigol RP1018H Oscilloscope 150 Mhz Passive High Voltage Probe

High voltage probe can prevent high voltage testers from subjecting to unexpected shocks when doing high voltage measurement work. Before using the high voltage probe, the operator must read and fully understand the safety rules. In addition, this high voltage probe only for the person who are trained, experienced, or otherwise qualified to recognize hazardous situations and who trained in the safety precautions that necessary to avoid possible injury when using such a device.

For digital oscilloscopes, the signal under test needs to be connected to the measurement channel via various oscilloscope probes or 50 ohm cables. The Probing is very important to making quality measurements. If the probe performance is not adequate or if you did not select the proper probe for your application, you will see distorted or misleading signals on your oscilloscope.

There are two kinds of probes, one is passive probe, another one is active probe. active probe requires power while passive probe does not. For general-purpose measurements(<600MHz), passive high-impedance resistor divider probes are good choices in general. For high-frequency applications (>600 MHz), active probes are the way to go. They cost more than passive probe and their input voltage is limited, but because of their significantly lower capacitive loading, they give you more accurate insight into fast signals.
