DATA SHEET N28xxA/B Passive Probes Introduction The Keysight N28xxA/B low-cost, general-purpose passive probes provide up to 500 MHz bandwidth and feature a high input resistance of 10 MΩ for low probe loading. These probes provide a 10:1 attenuation ratio except for the N2889A which provides a switch in the probe handle for switching the attenuation ratio between 1:1 and 10:1. The probes are compatible with Keysight InfiniiVision and Infiniium Series oscilloscopes with 1 MΩ BNC input. The N284xA Series passive probes are the frequency tuned versions of the N2862B/63B/89A/90A, offering more linear frequency response with Keysight oscilloscopes

Compensation Adjustments These probes can be adjusted for low-frequency and high-frequency compensation. For the best measurement results you should compensate your probe to match its characteristics to the oscilloscope. A poorly compensated probe can introduce measurement errors. Low-frequency compensation should be performed before performing high-frequency compensation. Low-frequency compensation 1. Connect the probe from the appropriate oscilloscope channel to the 1-kHz square wave source. 2. Press Autoscale. Adjust the oscilloscope to display two to three cycles of the waveform over two...
