Performance Characteristics

* Denotes Warranted Specifications, all others are typical. Specifications are valid after a 30-minute warm-up period, and ±10°C (models 54810A/15A/20A/25A) or
±5°C (models 54835A/45A) from firmware calibration temperature.

AutoProbe Interface

AutoProbe is an intelligent communication and power link between compatible probes and Infiniium scopes.
AutoProbe completely configures the scope for the attached probe. For instance, it identifies the probe type
and sets up the proper input impedance, attenuation ratio, probe power and offset range, as needed.
