Recognizing and Reducing Data Acquisition Switching Transients - White Paper
Low impedance sources can produce large and fast current transients when switching; creating problems with adjacent channels, transients in the ground circuit that upset digital logic connected to the DUT, or causing the switch unit to reset or hang. This application note describes several techniques to reduce these switching transients.

Probing a Midpoint of a Transmission Line that is Not Load Terminated - White Paper
With the advent of variable on die termination (i.e. ODT) many systems like low power double data rate memory (LPDDR) have the ability to either terminate a line in its characteristic impedance for high speed operation or terminate it with an open for lower speed operation. Many times there is a desire to probe the transmission line to monitor the signals on the line. When the transmission line is terminated in close to its characteristic impedance, the signals can be readily observed. However, if the line is terminated in an impedance that is not close to the characteristic impedance then it may not be possible to accurately measure the signals.

Bandwidth Boosting Techniques for the Infiniimax Probe Amp and Probe Head - Application Note
Keysight InfiniiMax differential probes are DSP corrected to have a flat magnitude and phase response to provide the highest possible accuracy. The bandwidth chosen to correct to is typically around 3dB non-corrected bandwidth. Usually, extending the bandwidth much beyond that point will increase the noise floor, and if pushed even further, can cause unrealistic noise artifacts. However, the N5381A/B solder-in probe head in combination with the InfiniiMax 1169A/B probe amp is an excellent candidate for extending the bandwidth beyond the 3dB point because the N5381A/B is peaked past the normal 12 GHz bandwidth, and the peaking of the probe head can help compensate for the roll-off of the probe amp bandwidth.
