N2884A InfiniiMax differential fine-wire probing tip

Загрузить техническое описание

The N2884A InfiniiMax differential fine-wire probing tip is a high fidelity, high bandwidth solution for probing an active IC. It is targeted at R&D and test engineers using an oscilloscope for debugging and testing ICs. The N2884A provides an innovative differential probing approach that is unmatched by any competitors in the market.

Leveraging Keysight’s low-cost ZIF probe head technology, the N2884A is designed to offer you a flat frequency response over the entire 12 GHz bandwidth specification, which eliminates the distortion and loading that affect probes with in-band resonance. Unlike other market solutions which measure a voltage versus some ground far away from the probe point, the N2884A measures a voltage versus an adjacent local ground (or other node) on the DUT. This results in greater rejection of common mode noise and superior signal integrity in measurement.

The N2884A comes with a probe arm and a set of 5 probe tips. The probe arm is compatible with the Wentworth Laboratories micropositioner as shown in the picture. You can either order it directly from Wentworth Laboratories - www.wentworthlabs.com.

or you can order it from Keysight. If you order it through Keysight, you must order the following two parts:

• N2884-64702 (Wentworth 2026-90409 PVX 400-M: Manual Linear Manipulator Magnetic Base)
• N2884-64703 (Wentworth 5-00-4711 Short Nose Articulated Short Arm Front)
