Page 4: Safety Information
(these apply to the accessories in the N2879A kit and the N2870A Series probes). Be aware that if you use this probe assembly in a manner not specified, the protection this product provides may be impaired. - Page 5 Accessory Details Accessory Details Below is information regarding some of the accessories in the N2879A Fine Pitch Accessory Kit. Replacing Rigid/Solid Probe Tips and Spring- Loaded Probe Tips These solid tips and spring-loaded tips are replaceable. To change the probe tip, use pliers to grip the tip and pull it straight out of its contact socket along the axis of the probe.
- Page 6 Accessory Details Short Ground Blade / Ground Spring The short ground blade is the best performing ground connection available with the N2870A Series due to its low inductance. To attach the ground blade, simply push it over the probe tip and continue pushing until the blade is inserted into the notch located on the probe barrel (as shown in the picture below - Note that the ground blade was placed over the tip and then an IC cap was placed over it as well in the picture).
- Page 7 Accessory Details Dual Adapter, 2.5 to 0.8 mm Sockets The dual lead adapter offers a convenient and reliable method to connect both the probe signal and ground to probe points on the board or other probe accessories. For example, this can used to connect to connector headers or to other accessories like the QFP clips or pico hooks (see the picture in the Pico Hook section of this manual).
- Page 8 Accessory Details Pico Hooks / QFP IC Clips You can use pico hooks or QFP IC clips to make connections to components or wires with leads that are 1.01 mm (0.04 inches) in diameter or smaller. With today’s miniature IC- and component-packaging techniques, the pico hooks or QFP IC clips can make probing challenging devices much easier.
- Page 9 Accessory Details The different colored IC caps correspond to different pitches (see diagram below to see how pitch is measured and refer to the table on page 3 to see what pitch each color corresponds to). The IC caps are compatible with both the rigid and spring loaded tips.
- Page 10 Accessory Details PCB Adapter Kit The PCB Adapter sockets are designed to solder into a printed circuit board (PCB) as test points to minimize ground inductance and maximize signal fidelity. Below is a picture showing one of these PCB sockets attached to a PCB. The recommended PCB layout is shown in the manual that accompanied your N2870A Series probe.
- Page 11 Accessory Details Micro-SMD Clip The micro-SMD clip is a spring loaded, two-pole test clip specially designed for SMD components. It features a gold-plated, hardened tip for testing circuits and has flat-nosed grips for individual components. Its balanced spring force enables you to test both large and small components.
