Agilent/Keysight N2830A

The Agilent/Keysight N2830A is an InfiniiMax III+ Series probe amplifier engineered for signal acquisition and complex measurement analysis. Operating at 4 GHz bandwidth with 108.5 psec rise time, it delivers the low-loading characteristics and measurement flexibility demanded in precision test environments. InfiniiMode technology enables dynamic switching between differential, single-ended (A or B), and common mode configurations without physically altering probe connections - a significant advantage when probing complex circuits or conducting comparative measurements.
