DATA SHEE T N2750A/51A/52A InfiniiMode Differential Active Probes
Key Features Measurement Versatility Measurement versatility These probes integrate many of the features and characteristics needed for today’s general-purpose, high-speed differential probing - especially in digital system design, component design/ characterization, and differential serial bus measurements. The N2750A Series differential probes offer 2:1 and 10:1 dual attenuation settings, allowing them to be used for a broad range of applications.
Superb Usability InfiniiMode The N2750A Series probes come with new InfiniiMode operation modes. The InfiniiMode allows convenient measurements of differential, single-ended, and common mode signals with a single probe tip without reconnecting the probe to change the connection. The N2750A probe’s InfiniiMode provides the following modes of operation. –– A – B (differential) –– A – ground (single-ended A) –– B – ground (single-ended B) –– (A+B)/2 – ground (common mode) Figure 1.
Flexibility in probe use models is also a vital necessity. The probes come standard with three different types of exchangeable probe tips that allow for easy connections to the circuit under test. These probe tips enable you to access multiple signals on anything from header connectors to hard-to-reach, high-density circuitry. The probes are equipped with a white LED headlight to illuminate the circuit under test which will help you see where you are probing.
