– Key Features
Differential measurement capability with switchable 10:1 and 5:1 attenuation ratios accommodates both high-amplitude and low-level signals. The 50 kΩ differential input impedance and minimal 0.27 pF capacitive loading preserve signal integrity on sensitive test nodes. AutoProbe1 connectivity eliminates manual probe configuration on compatible Infiniium platforms.
– Typical Applications
High-speed digital protocol analysis, analog signal characterization in RF circuits, power integrity measurements, and mixed-signal debugging in complex integrated circuits.
