Agilent Technologies Inc. (www.agilent.com) has unveiled a new software for its Infiniium 90000 X-Series and 90000A Series oscilloscopes, the PrecisionProbe software.
This new software provides the oscilloscope automatic characterization and correction capabilities, eliminating the need for external equipment. The analysis delivered by this new software significantly improves measurement margins allowing engineers to make accurate measurements.
Although great caution is taken to prevent channel loss in probing systems such as Agilent’s Infiniimax III, probes and cables are naturally lossy. Sometimes the loss is just enough to alter measurements, resulting to inconsistencies, at other times the loss is substantial. Moreover, phase characteristics and frequency response of probes can vary. Thus, each cable and probe must be accounted for and characterized to ensure the accurate representation of the signal.
With N2809A PrecisionProbe software, engineers can overcome these challenges by correcting probing issues such as magnitude flatness and phase linearity, instantly correcting for channel and cable insertion loss, compensating and characterizing for loss on channel paths without including additional equipment, matching frequency phase and response of each probe and cable on a circuit, and by characterizing probe impedance profiles.
PrecisionProbe offers not only skew correction and DC calibration, but AC calibration as well. It does not rely on externally produced s-parameter characterization files, which are usually generated from other devices such as vector network analyzers or time-domain reflectometers. Instead, the new software uses an integrated signal source on the oscilloscope to automatically produce the files.
