The company has also introduced an active termination adapter that provides ultra-low noise voltage termination to an ungrounded signal and QuickTip accessories for InfiniiMax I/II probes that will help engineers make fast and reliable measurements.
The InfiniiMax III+ probes work with all InfiniiMax III probe heads, including a wide range of soldering probe heads, a browser head, ZIF (zero insertion force) tips, SMA, 2.92 mm and 3.5 mm probe heads, and the QuickTip head. These probe solutions complement the new Infiniium V Series oscilloscopes with their revolutionary, industry-leading performance, accuracy, and ease of use.
Keysight's InfiniiMax III+ probes feature InfiniiMode technology, which greatly expands the probe's measurement capabilities to the point of being able to measure all components of a differential signal. With a single connection, engineers can configure the InfiniiMax III+ to measure the differential signal, single-ended A or B signals, and the common-mode component of a differential signal.
As with InfiniiMax III technology, the unique S-parameters of each InfiniiMax III+ probe amplifier are stored within the amplifier itself and used in conjunction with the S-parameters of the various probe heads. This further flattens the probe's magnitude and phase response for greater accuracy.
To date, most oscilloscopes with 50-ohm inputs are grounded. However, some communication system standards, such as HDMI 2.0, DisplayPort, and MIPI M-PHY Gear 3/4, require 50-ohm termination to a voltage rather than ground. The Keysight N7010A active termination adapter is a 30 GHz unipolar adapter that features a user-adjustable common termination voltage (VTERM) and extremely low-noise performance. The oscilloscope can internally control the termination voltage to maintain it between -4.0 V and +4.0 V. Using a low attenuation ratio setting (1.16:1), the adapter enables extremely low noise levels.
Soldering iron probe heads are commonly used to probe high-speed signals. Unfortunately, soldering iron probes are not the ideal solution when moving between multiple test points on a board. The QuickTip probe head for InfiniiMax I/II N2851A provides the industry's only quick on/off functionality when measuring multiple high-speed test points. The QuickTip design uses three small gold-plated magnets as contacts for the gold-plated steel buttons on the probe tip. Engineers can install multiple N2849A probe tips on a device under test, enabling fast and reliable multi-probe point measurements.
“Keysight believes we must innovate on multiple fronts to provide our customers with more insights,” said Dave Cipriani, vice president and general manager of Keysight’s Oscilloscopes and Protocols Division. “Simply advancing an announced specification doesn’t help them. That’s why Keysight is introducing a family of oscilloscopes and polling solutions today that offer new functionality while improving ease of use.”.
