In the fields of power electronics, industrial automation, new energy (such as photovoltaic inverters, electric vehicle charging piles), and the R&D and testing of household appliances, engineers often face the challenge of high-voltage signal measurement. Traditional probes or improper measurement methods may not only lead to data distortion, but also bring huge potential safety risks. How to capture voltage signals up to hundreds or even thousands of volts safely, accurately and conveniently? Keysight N2870B passive high-voltage probe is the professional solution designed for this demand!

N2870B: A core tool specially designed for high-voltage measurement

As a classic passive probe with 100:1 attenuation ratio launched by Keysight Technologies, N2870B combines high performance, high safety and ease of use. It is your ideal partner to expand oscilloscope measurement capabilities and cope with high-voltage test scenarios.

Core Advantages for Professional Measurements:

1. Outstanding High Voltage Measurement Capability:

• Up to 1000V RMS / 1500V peak voltage measurement range (CAT I) meets the needs of most high voltage test applications.

• For industrial environments, it comes with CAT III 600V safety certification to ensure safe measurement in scenarios with high-energy transient risks such as power distribution systems, protecting the safety of personnel and equipment.

2. Accurate and Reliable Data Capture:

• With 100MHz bandwidth, it can clearly capture fast transients and details in high-voltage signals, ensuring waveform fidelity.

• 100:1 attenuation ratio effectively reduces the impact of high voltage on the oscilloscope input channel, while allowing the oscilloscope to use more sensitive range settings, improving measurement resolution and accuracy.

3. High input impedance (40 MΩ || 4 pF) significantly reduces the loading effect of the probe on the circuit under test, avoids interference with the true state of the measured signal, and delivers more accurate measurement results.

4. Rugged Design, Safety First:

• The design complies with strict CAT III 600V / CAT II 1000V safety standards, providing reliable electrical isolation and insulation protection.

• It is equipped with safety-grounded alligator clip and insulating sheath as standard, forcing users to establish a good ground connection and minimize the risk of electric shock.

• The rugged probe body and accessories are durable and adaptable to various working environments.

5. Plug-and-Play, Convenient and Efficient:

• Compatible with most oscilloscopes with bandwidth of 100MHz and above (requires standard BNC input interface).

• No external power required, plug-and-play, simple setup, greatly improving work efficiency.

• A variety of accessories (probe tip, hook, ground lead, insulating sheath, etc.) are included as standard to easily handle different connection scenarios.

6. Keysight Quality Assurance:

• Sourced from the global leader in the test and measurement industry, it delivers reliable quality and stable performance.

• We provide comprehensive calibration and after-sales service support.
