The InfiniiMax II Series 1168B 10 GHz probing system for Infiniium oscilloscopes provides full real-time bandwidth to 10 GHz. The award-winning InfiniiMax probing system supports even the most demanding mechanical access requirements without sacrificing performance.
With only 3.4:1 of attenuation ratio, the 1168A/69A provides the lowest probe noise floor among InfiniiMax probes, making it ideal for signal integrity measurements that require high sensitivity. The 1168A/69A probe system supports a wide variety of real-world applications with an extensive line up of probe heads and accessories. Unrivaled InfiniiMax probe accessories support browsing, solder-in, socketed, ZIF tip, QuickTip (magnetic tip), soft touch head and SMA head solutions with various options to choose from.
The 1168B is the RoHS compliant version of the 1168A. The 1168B is 100% form, fit, function and price equivalent to the 1168A.

Notes:
¹ Input Impedance Profile: RCRC architecture is the best choice for signals with low source impedance and RC architecture is the best choice for measuring signals that transition to low power modes because it has lower loading.
² Probe noise listed is the most common setup. Probe noise can vary with multiple factors such as attenuation ratio, probe head, and probe mode.
³ Measure differential, single-ended, and common mode signals.
⁴ Auto selected based on volts/division (all modes).
