Keysight N2870A Series Passive Probes and Accessories Data Sheet
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.
03 | Keysight | N2870A Series Passive Probes and Accessories - Data Sheet Easy Access to Signals The compact design with a 2.5 mm probe tip diameter provides better visibility to the circuit under test than conventional 5 mm or 3.5 mm probe tips. This makes it easier to probe today’s fine pitched space ICs and components. In addition, the replaceable probe tip is spring loaded, keeping it from slipping off the device you are probing.
04 | Keysight | N2870A Series Passive Probes and Accessories - Data Sheet Variety of Connections Use the optional accessory kits to provide access to signals and components that are difficult to probe. Figure 4. The Keysight N2885A PCB adapter sockets are designed to solder into a printed circuit board (PCB) as test points to minimize ground inductance and maximize signal fidelity. This package contains 25 sockets. Figure 5.
05 | Keysight | N2870A Series Passive Probes and Accessories - Data Sheet Variety of Connections (Continued) Use the optional accessory kits to provide access to signals and components that are difficult to probe. Figure 6. With today’s miniature IC- and component-packaging techniques, probing can be a considerable challenge. Use 0.5 mm QFP IC clips with TQFP/PQFP packages with 0.5 mm lead pitch or greater, or use pico-hook clips made for connections over components or wires with leads up to 0.

An IC cap adapter and ground blade with optional N2786A two-leg probe positioner offers an ideal hands-free solution for short circuit-proof probing of a fine-pitch IC. The N2877A deluxe accessory kit and N2878A fine-pitch accessory kit contain one N2786A two-leg probe positioner.
