The N2840/1/2/3A and N2853A series probes are high impedance low-cost passive probes that provide a 10:1 attenuation and feature a high input resistance of 10 MΩ. These probes can be adjusted for low-frequency and high-frequency compensation.
These probes are calibrated to work effectively with oscilloscopes that have an input impedance of 1MΩ shunted by 5 to 30 pF of input capacitance.
With the exception of the N2840A, these probes include probe ID capability that allows most oscilloscopes, such as Keysight’s InfiniiVision and Infiniium series, to detect the probe’s impedance and attenuation ratio.
