Introduction
The N2870A Series passive probe family sets new standards in high performance probing of up to 1.5 GHz
bandwidth. These general purpose probes and accessories offer high quality measurements at a very
reasonable price.
Faithful reproduction of signals
The N2870A Series passive probes offer DC to 35 MHz, 200 MHz, 350 MHz, 500 MHz and 1.5 GHz
bandwidths and various attenuation factors to address a wide range of measurement needs. For general
purpose probing, you can use the N2873A 500 MHz model, which provides superior 10 MΩ input resistance,
9.5 pF of low input capacitance and low-inductance ground connection. This keeps probe loading low
enough to achieve high signal integrity measurements. The 1.5 GHz passive probe offers even lower input
capacitance for measuring faster edges more accurately, making it a low-cost alternative to an active probe.
All N2870A Series probes come with the probe ID readout feature, allowing the probe to be automatically
recognized when connected to most Keysight Technologies, Inc. oscilloscopes.
