N2870A Series Passive Probes and Accessories

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...

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. All N2870A Series probes come installed with one spring-loaded probe tip and four spare probe tips (2 spring-loaded tips, and 2 rigid tips). Figure 2. Sharp probe tip makes it easy to probe today’s fine pitched components. To minimize...

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. Micro SMD clips were specially designed to provide fast and convenient hands-free probing of surface mount chip resistors or capacitors. This part is included in the N2877A and N2879A accessory kits.

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 0.04” diameter or smaller. Figure 7. The dual lead adapter allows you to easily connect the N2870A Series probe to a popular 0.1” pin header with 0.025” square pins. This dual...
