Fnirsi P4100 Probe Oscilloscope Probe 100:1 Attenuation

The Fnirsi P4100 Probe Oscilloscope Probe 100:1 Attenuation is a professional high-voltage measurement tool designed for accurate signal analysis in service centers, laboratories, and electronics workshops. Offering a 100:1 attenuation ratio and a 100 MHz bandwidth, this probe is engineered to handle varying voltage levels and ensure reliable performance during complex electrical diagnostics. Built with durable ABS plastic and featuring a 1.1-meter cable, it provides the necessary reach and resilience for everyday professional use.

Advantages

The Fnirsi P4100 oscilloscope probe delivers exceptional measurement precision through its high input resistance of 100 MΩ and extremely low input capacitance of 6 pF, minimizing circuit loading during testing. A short rise time of just 3.5 ns allows for the faithful reproduction of dynamic waveforms and rapid signal changes. Its robust housing ensures resistance to heavy use, while the wide compensation range of 10 pF to 35 pF supports stable and accurate signal capture across various testing environments.

Suitable for

• Measuring high-voltage circuits up to 1000 V DC + ACPP
• Professional laboratory research and electronic circuit development
• Repair and maintenance in electronics service shops
• Educational demonstrations in technical schools and universities
• General signal analysis and waveform diagnostics

When it may not be suitable

This probe may not be suitable for low-voltage measurements where high attenuation is unnecessary or where maximum signal sensitivity is required without a 100:1 reduction. It is also not designed for ultra-high-frequency applications exceeding the 100 MHz bandwidth limit.

How to use

Connect the Fnirsi P4100 probe to your compatible oscilloscope input channel. Adjust the compensation using the included screwdriver and the compensation range settings to match your oscilloscope input characteristics before taking measurements. Attach the appropriate test leads or positioning sleeves depending on the measurement point requirements. Ensure that the circuit under test does not exceed the maximum operating voltage limits before connecting the probe tip.

What to consider before purchase

• Verify that your oscilloscope is compatible with high-voltage probes and standard BNC connections
• Confirm that your typical measurement tasks require a 100:1 attenuation ratio
• Check that the 100 MHz bandwidth meets your frequency analysis requirements
• Ensure the maximum voltage of your circuits does not exceed 1000 V DC + ACPP

Usage recommendations: Always calibrate and compensate the probe with your oscilloscope before performing critical high-voltage measurements to ensure signal accuracy and operator safety.
